IS型单级单吸离心泵类型及操作方法

IS型单级单吸离心泵类型及操作方法IS(IR、IY）单单吸离心泵是按标准设计，通用化程度高。

IS型单单吸离心泵按用途可分为：IS：用于输送清水或物理化学性质类似于清水的介质，介质温度≤80℃IR：用于输送热水或者物理化学性质类似于清水的介质，介质温度≤150℃IY：用于输送不含固体颗粒，粘度小于120CST的无腐蚀油类产品，介质温度-20℃~250℃IS（IR、IY）单单吸离心泵为卧式安装，水平轴向吸入，向上径向吐出。

泵为悬架式结构，检修时不需拆卸进、出口管路，即可退出转子部件进行检修。

泵是通过普通弹性联轴器或加长弹性联轴器与电动机联结，泵的轴封采用软填料密封。

轴承为单列向心球轴承，采用润滑油润滑。

由电机通过连轴器与泵轴连接，带动叶轮旋转。

叶轮中的叶片迫使液体旋转，对液体做功，使其能量增加，液体在离心力的作用下，向叶轮四周甩出，通过泵体的涡形流道将速度能转换成压力能，当叶轮内的液体甩出后，叶轮内的压力低于进水管内压力，新的液体在压力差的作用下吸入叶轮，液体就连续不断的从泵内流出。

IS(IR、IY）单单吸离心泵操作使用IS型单单吸离心泵开车前的准备：1、检查轴承体储油室油位2、检查联轴器防护罩固定牢固3、关闭泵出口阀门因离心泵启动时，泵的出口管路内还没液体，因此还不存在管路阻力和提升高度阻力，在泵启动后，泵扬程很低，流量很大，此时泵电机（轴功率）输出很大，很容易超载，就会使泵的电机及线路损坏，因此启动时要关闭出口阀，才能使泵正常运行。

4、打开泵进口阀门有排空阀的打开排空阀，让液体充满整个泵腔，泵内气体排净后关闭排空阀，有冷却水的要打开冷却水开关。

IS型单单吸离心泵结构图IS(IR、IY）单级单吸离心泵开车：1、按下电源开关，当泵达到正常转速时，再缓慢打开（防止水锤现象）出口阀门在有压管路中，由于某种外界原因（如阀门突然启闭，断电）使水的流速发生突然变化，从而引起压强急剧升高降低的交替变化，这种水力现象称为水击或水锤。

IS单级单吸清水离心泵产品说明

IS单级单吸清水离心泵产品说明用途及特点IS、IR型泵是卧式单级单吸清水离心泵，用于工农业及城市、排水、消防供水等。

供吸送清水及物理化学性质类似水不含固体颗粒的液体。

它广泛适用于工农业及城市、排水、消防供水等。

IS、IR型泵系根据国际标准IS02858所规定的性能和尺寸设计，其技术标准均向国际标准靠拢，达到国际先进水平。

它是我国推广的节能泵类产品之一。

本泵结构简单，性能可靠，体积小，重量轻，抗汽蚀性能好，电耗低，使用维修方便。

IS、IR型泵通用性广，全系列共140种规格，但只用四种轴；同一规格的轴，轴承，轴封，能互换；全系列泵的悬架也只有四种。

泵转速分为2900和1450转／分两种。

性能如下：2900转／分1450转／分最大流量：240ｍ3／分400ｍ3／分最高总扬程：125ｍ55ｍ最高转速：3500转／分(用于60调波电源时，叶轮直径有所减少)最高工作温度：80℃允许吸入管路压力0.3MPa，泵的最高使用压力1.6MPa。

结构说明本泵为后开式，拆开泵盖和叶轮时不需拆卸吸水和排出管路。

悬架内装有两个滚珠轴承，用机器油或润滑脂润滑。

泵通过弹性联轴器由电动机直接驱动。

涡室、脚、进水法兰和出水法兰铸成一个整体。

结构图IS、IR型泵系根据国家标准ISO2858所规定的性能和尺寸设计的，主要由泵体（1）、泵盖（2）、叶轮（3）、轴（4）、密封环（5）、轴套及悬架轴承部件（12）等所组成。

IS、IR型泵的泵体和录盖的部分，是从叶轮背面处剖分的，即通常所说的后开门结构形式。

其优点是检修方便，检修时不动泵体，吸入管路，排出管路和电动机，只需拆下加长联轴器的中间联接件，即可退出转子部件，进行检修。

泵的壳体（即泵体和泵盖）抅成泵的工作室、叶轮、轴和滚动轴承等为录的转子。

悬架轴承部件支承着泵的转子部件，滚动轴承承受泵的径向力和轴向力。

为了平衡泵的轴向力，大多数泵的叶轮前、后均设有密封环，并在叶轮后盖板上设有平衡孔，由于有些泵轴向力不大，叶轮背面未设密封环和平衡孔。

泵轴承承受叶轮的离心力和泵轴的轴向力，要求具有足够的强度和刚度。

4. 密封装置：用于确保泵体与泵轴之间的密封，防止液体泄漏。

常见的密封装置有填料密封和机械密封。

5. 电机：将旋转动力传递给泵轴，使叶轮高速旋转。

常见的电机类型有交流电动机和直流电动机。

工作原理离心泵的工作原理基于离心力的作用。

当电机带动泵轴旋转时，叶轮也开始旋转。

叶轮的高速旋转产生了离心力，使液体从进口被吸入泵体内部。

随着液体被吸入，泵体内的压力增加，液体被推入泵体出口，并通过管道输送到目标位置。

安装方法安装离心泵需要遵循以下步骤： 1. 准备工作：确定泵的安装位置，保证安装地面坚实平整。

检查电源电压和频率是否与泵匹配。

准备所需的工具和安装配件。

2. 安装泵体：将泵体放置在安装位置上，确保与管道连接口对齐。

使用螺栓将泵体固定在地面上。

3. 安装电机：将电机与泵轴连接，确保连接牢固。

将电机固定在合适的位置上，并与电源线连接。

4. 安装密封装置：根据泵的型号和密封装置的类型，选择适当的密封装置。

将密封装置安装在泵体和泵轴之间，确保密封良好。

5. 连接管道：使用管件和螺栓将泵的进口和出口与管道连接起来。

确保连接处密封良好，无泄漏。

6. 检查和测试：完成安装后，仔细检查所有连接处，确保没有松动。

接通电源，进行试运行，检查泵的工作是否正常。

文档编号:离心泵操作手册.DOC离心泵单元仿真培训系统操作说明书北京东方仿真技术有限责任公司二零零五年九月一.工艺流程说明1．离心泵工作原理基础在工业生产和国民经济的许多领域，常需对液体进行输送或加压，能完成此类任务的机械称为泵。

而其中靠离心作用的叫离心泵。

由于离心泵具有结构简单，性能稳定，检修方便，操作容易和适应性强等特点，在化工生产中应用十分广泛，据统计超过液体输送设备的80%。

所以，离心泵的操作是化工生产中的最基本的操作。

离心泵由吸入管，排出管和离心泵主体组成。

离心泵主体分为转动部分和固定部分。

转动部分由电机带动旋转，将能量传递给被输送的部分，主要包括叶轮和泵轴。

固定部分包括泵壳，导轮，密封装置等。

叶轮是离心泵中使液体接受外加能量的部件。

泵轴的作用是把电动机的能量传递给叶轮。

泵壳是通道截面积逐渐扩大的蜗形壳体，它将液体限定在一定的空间里，并将液体大部分动能转化为静压能。

导轮是一组与叶轮旋转方向相适应，且固定于泵壳上的叶片。

密封装置的作用是防止液体的泄漏或空气的倒吸入泵内。

启动灌满了被输送液体的离心泵后，在电机的作用下，泵轴带动叶轮一起旋转，叶轮的叶片推动其间的液体转动，在离心力的作用下，液体被甩向叶轮边缘并获得动能；在导轮的引领下沿流通截面积逐渐扩大的泵壳流向排出管，液体流速逐渐降低，而静压能增大。

排出管的增压液体经管路即可送往目的地。

与此同时，叶轮中心因为液体被甩出而形成一定的真空，因贮槽液面上方压强大于叶轮中心处，在压力差的作用下，液体不断从吸入管进入泵内，以填补被排出的液体位置。

因此，只要叶轮不断旋转，液体便不断的被吸入和排出。

由此，离心泵之所以能输送液体，主要是依靠高速旋转的叶轮。

离心泵的操作中有两种现象应当避免：气缚和气蚀。

气缚是指在启动泵前泵内没有灌满被输送的液体，或在运转过程中泵内渗入了空气，因为气体的密度小于液体，产生的离心力小，无法把空气甩出去，导致叶轮中心所形成的真空度不足以将液体吸入泵内，尽管此时叶轮在不停的旋转，却由于离心泵失去了自吸能力而无法输送液体，这种现象称为气缚。

IS、ISR、ISY型泵安装使用说明书

IS、ISR、ISY型泵安装使用说明书一、结构说明1、IS型泵系列根据国际标准ISO2858所规定的性能和尺寸设计的，除泵体外，其余零件如泵盖、叶轮、轴、密封环、轴套及悬架体、滚动轴承等组成转子部件。

泵的转子部件用螺栓与泵体联接，检修时可取出整个部件，不需移动泵体和进、出水管路。

泵的壳体（即泵体和泵盖）构成泵的工作室。

为了平衡泵的轴向力，大多数泵的叶轮前、后均设有密封环，并在叶轮后盖板上设有平衡孔。

由于有些泵的轴向力不大，叶轮背面未设密封环和平衡孔，其轴向力则由滚动轴承承受。

2、泵的轴封结构（1）、泵的轴向软填料密封系统是由填料压盖、填料环和填料等组成，以防止进气或大量漏水。

泵的叶轮如有平衡孔，则装软填料的空腔与叶轮吸入口相通。

若叶轮入口处液体处于真空状态，则很容易沿着轴套表面进气，故在填料腔内装有填料环，通过泵盖的串水孔，将泵室压力水引至填料环进行密封。

为避免轴磨损，在轴通过填料腔的部位装有轴套保护。

轴套与轴之间装有O型密封圈，以防沿着配合表面进气或漏水。

（2）、泵的机械密封系统是由压盖、平垫、挡圈、短轴套和机械密封件等组成，属单端面非平衡型机械密封。

机械密封件的主要安装尺寸符合DIN24960标准。

图二注出了有关尺寸供用户更换时参考。

若用户更换的机械密封件的轴向尺寸较长、可减少S值或缩小短轴套的长度（当S=0）。

装机械密封的泵，泵盖的串水孔端部应装节流塞，使少量的水进入填料腔。

（3）、泵的橡胶油封系统多用于ISY型输油泵，是由填料压盖、普通型骨架式橡胶油封和封油环组成。

封油环内充满润滑脂，对轴套与油封间的运动起润滑作用。

采用橡胶油封时，泵盖上没有引导压力液体至填料腔的小孔。

3、ISR型热水泵的泵盖与悬架体之间增加一个冷却室盖，在冷却室盖和泵盖之间的空腔中通入冷却水，冷却轴封部位，以防止热量传入轴承。

在输送热水时，泵的进口压力不低于下表的规定，以免发生气蚀。

二、装配与拆卸泵在装配前应首先检查零件有无影响装配的缺陷，并擦拭干净，方可进行装配。

If the equipment is installed at a dangerous area, the relevant local anti-explosion rules, the equipment inspection qualification rules and the rules stipulated by the management organization responsible for approval must be abided by. The inspection certificate must be placed near the location where the pump set is running.3.2 The check-up prior to installationBased on the designated size stated in the installation diagram, all the necessary work must be well prepared. According to the standard, there must be sufficient strength to make the installation safe and reliable. Before the pump set is placed onto the foundation, the concrete foundation must be firm and the surface shall be very smooth and flat.3.3 The installation of the pump/pump set3.3.1 Installation (on-site)1) Before the installation, the concrete foundation must be very firm and the surface must be smooth and flat.2) Place the foot bolts into the foot holes on the base. Put the pump onto the foundation, make adjustment over the leveling with a gradimeter at the shaft end or outlet. The block must be placed next to foot bolts between the base and the foundation.3) After the leveling is adjusted, the foot bolts shall be grouted. After the mortar becomes solidified, the bolts shall be screwed down uniformly and then its leveling must be re-adjusted. Then the base shall be grouted.3.3.2 The installation of pump & motor with a common baseThe pump installation must be carried out by those well-trained personnel who have rich experience in installation.The installation form for the installation of pump and motor with a common base:1) Have a measure and keep a record of the pump location2) Put the pump set onto the foundation. Place the foot bolts into the base and make someadjustments. There shall be space of 4-5cm between the base and the foundation.3) Grout the foundation and make it solidified.4) Adjust the pump set accurately with the adjustment bolts and make alignment at thecoupling.5) Screw down the foot bolt uniformly.6) Grout the foundation. Have a re-checkup. If needed, the re-adjustment shall be carriedout(with washers)3.3.3 The adjustment of the pump & motorIt must be guaranteed that the pump and motor must be aligned accurately at the coupling. Even if the pump and motor are provided as a complete set, the alignment must be made if needed.Means: If the tolerance between the radial force and axial force does not exceed 0.1mm, in which case it is considered as well-aligned. The gauge shall be turned at an angle of 90 uniformly at both ends of the coupling for each time, which is to be tested with a noinus caliper or a micrometer caliper. All the readings must be uniform.Before the pump is being operated, the running data shall be checked up to be assured of the data marked on the nameplate. For instance, the working pressure, frequency, the temperature of the liquid transmitted, etc must be in line with the data in the contract and systematic data.3.3.4 The disassembly of the pump motor protective deviceFor those pumps of horizontal installation, it is unnecessary to remove the protective device, and so there is no protective device for this type of pump3.4 Pipe connectionATTENTION! Do not make the pump itself become the pipe support point. The suction pipe shall be displayed aslant upwards. The reverse-grouting pipe shall be laid aslant downwards. The pump inlet is required to be cut short, and the device NPSH must be exceeding the pump NPSH. A reliable support shall be set near the pump, without bearing any stress or anydistortion. Their weights can not apply any load onto the pump. For the short pipes, their nominal diameter shall be equal to the pump inlet and outlet nominal diameter at least. For the long pipes, the most economical diameter shall be decided based upon the specific conditions.Pay attention to the outlet and inlet additional load brought about by the following reasons: The weight of the filled pipe, the changes over the pipe length as a result of temperature rise, the counter-force resulting from the looseness of the slip joint, all of which can not exceed the certain value specified.If there is too much strength on the pipe or the strength value exceeds the allowable limit, then the pump leakage shall be brought about, in which case, the medium transmitted may float out into the air and so when it comes to transmitting hot medium, a person‟s lift may be threatened! Before the pipe is being installed, the inlet and outlet flange cover must be removed.3.4.1 Auxiliary pipesIf the auxiliary device is needed for the pump (for instance, cooling, heating, sealing, flushing and lubrication, etc), the connection shall be made according to the size and location marked on the assembly diagram or referring to the auxiliary pipe illustration. More information can be referred to the relevant chapter about the auxiliary pipes in the corresponding instruction manuals.The installation of these auxiliary pipes can facilitate the pump normal operation, which has significant meaning.3.4.2 Coupling guard coverThe pump can not be operated without the coupling guard cover so as to avoid accidents. If the customer does not need to install the guard cover for the delivery, the operator must install one.3.5 The final check-upPlease check up for another time whether the adjustment is right or not.The shaft can be turned over easily with hands( the coupling drives the shaft to rotate)Check on whether all the pipes are fixed firmly or not and whether they can be operated normally.3.0 The operation, start-up/turn-offPlease carry out the job as requested by the following to avoid the failures resulting from the non-conformance with the rules and regulations.4.1 The check-up prior to the operationThe followings shall be checked up before the pump is being started up:Whether the pump base and foundation are fixed firmly or notWhether the coupling and pump set is made adjustment or notWhether the pipe is connected as requested or notWhether the motor is installed in accordance with the use manual or notWhether the rotor can be turned over easily with hands ( at least one circle) or notWhether the coupling guard cover has been well installed or notWhether the operators know well possible failures and some relevant rules that they must conform to or notWhether the overload has been eliminatedWhether the shaft seal is installed according to the use manual or notIf the auxiliary devices have been provided, whether these devices are being installed according to the use manual or notWhether all these bearings have been well lubricated or notWhether the air in the pump has been discharged or not4.2 Shaft sealWhile the shaft seal is being installed, please refer to the chapter of “shaft seal” in the manual. If the pump is not being used for a long period of time, the measures in chapter of 4.6 shall be taken.4.3 Air dischargeBefore the pump is being operated, the air inside the pump and pipe must be discharged fully and then get it fed with the medium. While it is sucking upwards, the plug holes on the casing shall be applied for air discharge. While the pump is being fed, the air inside the pump also needs to be discharged fully.4.4 Operation4.4.1 Check-up on the pump rotation directionThe pump rotation direction must be right. If the rotation direction is wrong, the pump shall not reach its working point, and then the vibration and over-heating shall arise, and the pump set or shaft seal may also be damaged.The correct rotation direction: The pump rotor direction must be in line with the arrow marked on the pump casing.The motor rotation direction can be confirmed through the means of contacting start-up buttonThe pump is not allowed to run dry.If there is no check valve at the outlet, the outlet valve shall be closed. If there are check valves, the inlet valve shall be opened fully.Open all the auxiliary pipes (cooling, heating, sealing, flushing and lubrication oil), and the capacity shall also be checked on.After the steps introduced in the chapter two have been finished, the motor can be turned on. While the system begins to transmit the medium, the pressure rise can be seen from the pressure gauge, and then the outlet valve can be opened slowly.The outlet valve can be closed only when the pump is being started up or turned off, otherwise, the pump shall be damaged resulted from overheating.4.4.3 The pump working rangeAccording to the O-H characteristic curves, the capacity of Q can be adjusted automatically to be adapted to the head changes. The pump allowable working range is limited, which is caused by several reasons.1) The working limit: the low capacity part overloadedThis limit is shown as Qmin in the Q-H characteristic curve, or it can be illustrated as the lengthened line in the un-drawn characteristic curve, which is illustrated as follows.The pump is not allowed to be operated within the range of Q=0-Qmin. If it has been running within the range for a long period of time, the mechanical seal overload shall be enhanced so that the parts can not bear. But it is allowed to pass the critical range just for an instant, for example, while the pump is being started up.2) Partial overload and the limit NPSH within the overload rangeThese two limits can be decided based on the relations between the NPSHR and NPSHA, which can be obtained through the following means:The intersection of NPSHR and NPSHA is projected onto the O-H characteristic curve, and these two points determine the working limit (indicating the part below the curve)The working limit of NPSH shall not be checked up while the pump is working under the designed working conditions. But if there is any change over the system, the NPSH value must be checked on. If needed, Sanlian company must be consulted for advice.Close the outlet valve. If there is any check valve at the outlet pipe, the outlet valve can be kept open so as to obtain a return pressure. While the pump is being turned off, the inlet valve shall not be closed. While the motor is being turned off, it must be guaranteed that the set can be turned off very smoothly. There shall be appropriate post-period of running time for the pump, during which period, the heating source must be turned off so that the medium transmitted can be cooling down completely to avoid any heat produced inside the pump. While the pump is not being used for a long period of time, the inlet valve must be closed.Close the auxiliary pipes. The sealing liquid lubrication must be applied even if it is in a state of turn-off.When it is being frozen or in disuse for a long period of time, the medium inside the pump and pipe must be eliminated to prevent it from frost cracking.4.5 Turn-off/storage/maintenanceEvery set of the pump goes through strict inspection when it is for delivery. When it comes to the pump storage, the following measures shall be taken.4.5.1 The storage of new pumpFor the new pump provided by Sanlian company, Sanlian has well prepared for its storage. In case the pump is being kept indoors according to the standard, the maximum storage time can reach 12 months. The pump shall be kept at a dry place.4.5.2 Measures taken in case of the long period of the disuse1) The pump shall be kept under the state of assembly, and the periodical check-up must becarried out. When the pump is in disuse for a long period of time, the pump shall be started up every 1 or 3 months (for about 5 minutes) to guarantee that the pump can be started up at any time to avoid any deposits from being produced at the inlet. Before the pump is operated, the operating status shall be checked up to guarantee that there is sufficient amount of liquid inside the pump to start up the pump.2) Remove the pump from the pipe and take a check-up according to the chapters from 5.1 to5.4. Apply protective agent onto the inner wall of the casing, especially, onto the impellergap. It shall be applied at the inlet and outlet, and then the inlet and outlet shall be covered (for example, with plastic cover or something similar)4.6 Running after storageThe pump shall be checked up and maintained as described in the chapter 5.1 and 5.2. Besides, please refer to the chapter of 4.1 “operation” and chapter 4.4.3 “working limit”. After the work mentioned above have been finished, all the safety protective devices shall bere-installed as requested before the pump set is to be started up and then put into operation.4.0 Maintenance5.1 Common regulationsPlease make sure that all the maintenance, check-up and installation must be carried out by those designated, qualified professionals who are fairly familiar with the manual.The periodical maintenance can avoid the expensive maintenance fee to make the pump free from any failures. Furthermore, the pump can be operated reliably at a very low cost of maintenance fee.All the work mentioned above must be carried out while the electricity has been cut off to prevent the pump set from being started up all of a sudden (death of danger)When the pump transmit hazardous liquids, it must be sterilized. After the medium has been discharged completely, there is no danger for people and the environment. Besides, some relevant rules must be abided by (death of danger)5.2 Maintenance/check-up5.2.1 Operation managementThe following points must be paid great attention to while the pump is being operated:The pump must be operated stably.The pump is not allowed to run dryTo avoid the medium temperature rise, the pump can not be operated for a long period of time while the outlet valve has been closed.While the ambient temperature reaches 30 (80F),the bearing temperature can not exceed 90 (194F), while the temperature is rising, the bearing temperature can not exceed 100 (212F).If there is any inlet valve, it can not be closed while the pump is being operated.Take a periodical check-up and start up the standby pumpCheck on whether the auxiliary pipe has been well connected.Check on the flexible components on the coupling. If there is abrasion, please have replacement immediately.If it is not the working medium that is applied for sealing, cooling or lubrication oil, it must be guaranteed that the applied liquid pressure must be 1.0---2.0 bar higher than the inlet pressure. If the packing seal is applied for the pump, the fact that several drops of water dribble is allowed at the packing box during the operation. Press lightly the packing gland until there are little drops of water dribbling.5.2.2 The maintenance over the shaft sealFor the shaft seal for HS(V) pump, it can be provided of its own (or it can be provided from outside according to the working conditions). Prior to the start-up, the valves on the shaft seal water pipe shall be opened. After the start-up, the sealing condition of the shaft seal shall be watched on, and make adjustment over the shaft seal water volume and water pressure.The drop leakage shall be appropriate for the packing seal. Otherwise, the packing gland needs to be pressed tight. If there is still large volume of leakage after it has been adjusted to the maximum limit, the packing shall be replaced. For the mechanical seal, the pump needs to be turned over with hands to see whether the turn is easy and smooth. After the continuous running, the leakage volume shall not exceed 5ml/h, otherwise, it shall be stopped for a check on the shaft seal.5.2.3 The maintenance of bearingIt is unnecessary to maintain the deep groove ball bearing fro grease lubrication. If the thin oil lubrication bearing is applied, the chapter of “thin oil lubrication bearing” in the bearing use manual can be referred to for maintenance.5.3 DisassemblyPrior to the disassembly, please make sure that the pump shall not start running all of a sudden and the inlet valve and outlet valve must be closed. The pump must be cooled down to the ambient temperature. The pump must be discharged completely. The pressure must be released.The disassembly and re-assembly must be carried out in accordance with the relevant sectional view.5.3.1 Common regulations & suggestionsThe maintenance must be carried out by these professionals, and the original spare parts must be applied. The safety rules must be abided by. The operations relating to the electricity must be carried out according to the instructions and regulations made by some relevant motor plants.The disassembly and re-assembly must be carried out in accordance with the relevant overall installation diagram. Please look at the attachments for the overall installation diagram and some other relevant information. The disassembly can be carried out as described in the overall installation diagram.If there is any failure, please contact our sanlian service department.5.3.2 Disassembly preparationPlease refer to the chapter of “coupling” in the use manual. Without removing the inlet and outlet pipe or re-adjusting the pump location, the whole rotor part can be removed.The rotor part can be removed according to the following sequences:1) Close the inlet and outlet valve, let loose the water discharge plug and air discharge plugto get the pump well discharged.2) Remove all the auxiliary pipes on the pump3) Remove the coupling guard cover.4) Let loose and remove the seal cover.5) Let loose the flange screw, separate the pump casing from the pump cover with a cover-offscrew, lift the pump cover with a crane and place it at a sate location, in which case the maintenance can be carried out and the internal part of pump can be disassembled.6) If the thin oil lubrication is applied for the bearing, the thin oil shall be discharged.7) Remove the connection bolts between the bearing body and the bearing bracket. Let loosethe nuts and connection bolts of the non-drive bearing cover.8) Exit the bearing body from the channel. Lift the rotor out of the casing and place it at a safelocation for further disassembly.9) Remove the bearing body on the non-drive bearing10) Let loose and remove the round nut.11) Remove the deep groove ball bearing from the shaft, the shaft sleeve includes.12) Remove the bearing gland.13) Remove the v-ring from the shaft sleeve14) Remove the seal body15) Remove the shaft sleeve16) There is space between the impeller and the shaft, so normally the impeller can beremoved easily. If it can not be removed, a plastic hammer shall be applied to knock lightly at the impeller hub.17) Remove the other shaft sleeve and shaft seal18) Remove the pump coupling19) Remove the bearing body20) Let loose the flexible deflector and exit the deep groove bearing5.4 Re-assemblyThe re-assembly can be carried out counter to the disassembly process, and the overall installation diagram various part list can be referred to.The assembly and disassembly of the shaft seal, bearing, casing, and impeller seal ring must be carried out in accordance with the specified assembly technique or installation instruction, and the chapter of 5.5.1 and 5.5.2 must be referred to. If the thin oil lubrication bearing is applied for the pump, the chapter of “thin oil lubrication bearing” must be referred to.。
