风机静压,全压,动压
风机静压、动压、全压、余压的概念[字号:大中小] 2014-08-09 阅读次数：19a. 静压(Pi)由于空气分子不规则运动而撞击于管壁上产生的压力称为静压。
计算时，以绝对真空为计算零点的静压称为绝对静压。
以大气压力为零点的静压称为相对静压。
空调中的空气静压均指相对静压。
静压是单位体积气体所具有的势能，是一种力，它的表现将气体压缩、对管壁施压。
管道内气体的绝对静压，可以是正压，高于周围的大气压；也可以是负压，低于周围的大气压。
b. 动压(Pb) 指空气流动时产生的压力，只要风管内空气流动就具有一定的动压。
动压是单位体积气体所具有的动能，也是一种力，它的表现是使管内气体改变速度，动压只作用在气体的流动方向恒为正值。
c. 全压(Pq)全压是静压和动压的代数和： Pq＝Pi十Pb 全压代表单位气体所具有的总能量。
若以大气压为计算的起点，它可以是正值，亦可以是负值。
d. 机外余压机外余压的概念一般来自厂商样本样本上所提供的机外余压一般是考虑机组本身的压力损失后所能提供的全压，关于机外余压到底是机外全压还是机外静压？可以理解为机外全压，写成机外静压是测试时通常把动压看为0。
可见，机外余压的概念并非一个标准性概念,但必然是考虑机组本身的压力损失后所能提供的全压二.静压是由于分子运动力产生的对壁面的压能，在流场内各点大小都一致；动压是因为流体动量形成的压能，仅在迎着来流方向存在。
这是一对理论范畴。
全压是静压和动压的总和，反应了流体的做功能力水平。
在流体流动过程中，扣除阻力损失后，静压和动压会相互转化。
并不是不变的。
机外余压是风机克服自身阻力损失后的全压值，即进出口全压差。
风机出口风速较高，动压也较大，静压相对较低；但像有的AHU出口马上就进入一个静压箱，则在静压箱内几乎所有的风机能都转化为静压了。
所以我们一般说的风机压头都是说全压，反应的是这台风机的做功能力。
说风机动压和静压都是相对场合的说法，有特定条件的。
风机基础知识
风机基础知识风机基础知识⽬录风机的定义 (2)风机的分类 (2)叶轮分类 (2)轴流风机 (2)离⼼风机 (2)混流风机 (3)⽤途分类 (3)公司系列分类 (3)连接⽅式分类 (4)安装位置分类 (5)风机的常⽤参数 (5)风机相似率及计算公式 (8)风机基本零部件的认知和关键质量指标 (9)风机配套 (17)风机旋向的认知 (18)常⽤单位的换算 (18)风机的选型注意点 (19)风机基础知识⼀、风机的定义风机是将旋转的机械能转换成流动空⽓总压增加⽽使空⽓连续运动的动⼒机械。
另外也可以说风机是将旋转的机械能转换成⽓体的动能和势能,并将⽓体输送出去的⼀种动⼒机械。
⼆、风机的分类a)叶轮分类根据⽓流运动的特点分类也就是根据叶轮形式来分类可以分为离⼼风机、轴流风机、混流风机。
（⼀）轴流风机轴流叶轮的进风⽅向和出风⽅向相同。
⼀般⽤于风量较⼤，风压较底的场合。
英飞产品中轴流风机有：RTA/RSA、WEX/WSP、IAS、IA T等。
英飞边墙轴流风机（WEX/WSP）风量⼤，压⼒低，噪⾳低，使⽤前掠型叶⽚。
管道轴流风机风量⼤，压⼒相对较⾼，⼀般使⽤CAD流场模拟技术优化设计的钢制叶⽚或进⼝“⼩旋风”叶轮。
（⼆）离⼼风机离⼼叶轮的进风⽅向和出风⽅向呈90°。
⼀般适⽤于较⾼压⼒，较⼤风量的场合。
英飞产品离⼼风机：CBD/CFD、BC系列、RTC、ISQ、CUS、RSC、ICC 等。
离⼼叶轮可分为前弯叶轮、后倾叶轮、后弯叶轮。
1、前弯叶轮：⽓流⽅向和叶⽚的线速度⽅向夹⾓为锐⾓。
特点：低转速，⼤风量，低静压（相对后倾，后弯叶轮），成型⼯艺简单，成本低。
前弯叶轮转速过⾼会造成电机过载，所以使⽤前弯叶轮的风机不允许空载运⾏。
2、后倾叶轮：⽓流⽅向和叶⽚的线速度⽅向的夹⾓为钝⾓，叶⽚为直板形式。
特点：⾼转速，转速范围宽，风量⼩，⾼静压，不过载，效率⾼。
（相对前弯叶轮做⽐较）3、后弯叶轮：⽓流⽅向和叶⽚的线速度⽅向的夹⾓为钝⾓，叶⽚为曲⾯形式。

If any items are missing, report shortages to your local representative to arrange for obtaining missing parts. Sometimes it is not possible that all items for the unit be shipped together due to availability of transportation and truck space. Confirmation of shipment(s) must be limited to only items on the bill of lading.HandlingG Direct DriveLift unit on to the roof utilizing hooks under the lip of the shroud. Evenly space the hooks around the shroud using a minimum of four lifting straps. Use a spreader bar to ensure the straps do not come in contact with the unit (see Figure 1).GB Belt DriveWhen lifting the unit on to the roof, use either the four lifting points on the drive frame or the two lifting points on the bearing plate if present (see Figure 2 for lifting points). Access to the drive frame is accomplished by removing the screws pointed out in Figure 3. The cover can then be removed and placed on a flat surface in an area protected from strong winds.When G/GB unit is on the roof, move fan to desired location using lifting points and fasten securely through mounting holes in base. Shims may be necessary depending upon roofing material thickness.The motor amperage and voltage ratings must be checked for compatibility to supply voltage prior to final electrical connection. For G/GB installations, the electrical supply should be routed through the conduit chase located between the curb cap and the bottom of the motor compartment. Wiring must conform to local and national codes.2Model G/GB Centrifugal Roof Exhaust FansStorageFans are protected against damage during shipment. If the unit cannot be installed and operated immediately, precautions need to be taken to prevent deterioration of the unit during storage. The user assumes responsibility of the fan and accessories while in storage. The manufacturer will not be responsible for damage during storage. These suggestions are provided solely as a convenience to the user.IndoorThe ideal environment for the storage of fans and accessories is indoors, above grade, in a low humidity atmosphere which is sealed to prevent the entry of blowing dust, rain or snow. Temperatures should be evenly maintained between 30° to 110°F (-1° to43°C) (wide temperature swings may cause condensationand “sweating” of metal parts). All accessories must be stored indoors in a clean, dry atmosphere.Remove any accumulations of dirt, water, ice or snow and wipe dry before moving to indoor storage. To avoid “sweating” of metal parts, allow cold parts to reach room temperature. To dry parts and packages, use a portable electric heater to get rid of any moisture buildup. Leave coverings loose to permit air circulation and to allow for periodic inspection.The unit should be stored at least 3½ inches (89 mm)off the floor on wooden blocks covered with moisture proof paper or polyethylene sheathing. Aisles between parts and along all walls should be provided to permit air circulation and space for inspection.OutdoorFans designed for outdoor applications may be stored outdoors, if absolutely necessary. Roads or aisles for portable cranes and hauling equipment are needed.The fan should be placed on a level surface to prevent water from leaking into the fan. The fan should be elevated on an adequate number of wooden blocks so that it is above water and snow levels and has enough blocking to prevent it from settling into soft ground. Locate parts far enough apart to permit air circulation, sunlight and space for periodic inspection. To minimize water accumulation, place all fan parts on blocking supports so that rain water will run off.Do not cover parts with plastic film or tarps as these cause condensation of moisture from the air passing through heating and cooling cycles.Fan wheels should be blocked to prevent spinning caused by strong winds.Inspection and MaintenanceDuring StorageWhile in storage, inspect fans once per month. Keep a record of inspection and maintenance performed.If moisture or dirt accumulations are found on parts,the source should be located and eliminated. At each inspection, rotate the wheel by hand ten to fifteen revolutions to distribute lubricant on motor. If paint deterioration begins, consideration should be given to touch-up or repainting. Fans with special coatings may require special techniques for touch-up or repair. Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur. Immediately remove the original rust preventive coating with petroleum solvent and clean with lint-free cloths. Polish any remaining rust from surface with crocus cloth or fine emery paper and oil. Do not destroy the continuity of the surfaces. Thoroughly wipe clean with Tectyl® 506 (Ashland Inc.) or the equivalent.For hard to reach internal surfaces or for occasional use, consider using Tectyl® 511M Rust Preventive,WD-40® or the equivalent.Removing From StorageAs fans are removed from storage to be installed in their final location, they should be protected and maintained in a similar fashion until the fan equipment goes into operation.3 Model G/GB Centrifugal Roof Exhaust FansInstallationTypical Roof Mounting Installation1. On the roof surface, cut an appropriate sized holeand follow manufacturer’s instructions on curbinstallation. Caulk and flash the curb to ensure awater tight seal.2. If unit is equipped with a backdraft damper, it shouldbe installed now.3. Remove motor cover. Access to the motorcompartment is accomplished by removing thescrews as shown in Figure 3.4. Only on GB Belt Drive fans. On the drive frame usethe lifting lugs to lift and place the unit on top of roofcurb. (Refer to Figure 2 on page 2).5. Secure fan to curb using a minimum of eight lagscrews, metal screws or the suitable fasteners.Shims may be required depending upon curbinstallation and roofing material.Note: Severe duty applications may requireadditional fasteners.6. Verify power line wiring is de-energized beforeconnecting fan motor to power source.7. Connect power supply wiring to the motor asindicated on the motor nameplate or terminal boxcover. Check the power source for compatibility withthe requirements of your equipment.8. Check fan wheel for free rotation, re-centerif necessary.9. Check all fasteners for tightness.10. Mount and wire safety disconnect switch undermotor cover. Wire control switches at ground level,refer to Figure 4.11.

Always loosen tension enough to install belts withoutstretching, see Figure 9.9. For units with two groove pulleys, adjust so thetension is equal in both belts.10. If adjustments are made, it is very important to checkthe pulleys for proper alignment. Misaligned pulleys lead to excessive belt wear vibration, noise andpower loss, see Figure 10.Pre-Starting Checks1. Check all fasteners and set screws for tightness. Thewheel should rotate freely and be aligned as shown in Figure 7 below. 2. Wheel position is preset and the unit is test run at thefactory. Movement may occur during shipment and realignment may be necessary. 3. Only G unit - Centering height alignment can beaccomplished by loosening the set screws in the wheel and moving the wheel to the desired position. 4. Only GB unit - Centering can be accomplished byloosening the bolts holding the drive frame to the shock mounts and repositioning the drive frame. 5. Only GB unit - Wheel and inlet cone overlap can beadjusted by loosening the set screws in the wheel and moving the wheel to the desired position. 6. Only GB unit - Fan RPM should be checked andverified with a tachometer. 7. Check wheel rotation (viewing from the shaft side)by momentarily energizing the unit. Rotation should be clockwise as shown in Figure 8 and correspond to rotation decal on the unit. If wheel rotation is incorrect, reverse two of the wiring leads or check motor wiring for single phase.7Model G/GB Centrifugal Roof Exhaust FansInspectionInspection of the fan should be conducted at the first 30 minute and 24 hour intervals of satisfactory operation.30 Minute IntervalInspect bolts, setscrews and motor mounting bolts. Adjust and tighten as necessary.24 Hour IntervalCheck all internal components. On GB unit only, inspect belt alignment and tension. Adjust and tighten as necessary.Maintenance: G / GBInstallation and maintenance are to be performed only by qualified personnel who are familiar with local codes and regulations and who are experienced with this type of equipment.Motor maintenance is generally limited to cleaning and lubrication (where applicable). Cleaning should be limited to exterior surfaces only. Removing dust buildup onmotor housing ensures proper motor cooling.Greasing of motors is only intended when fittings are provided. Many fractional horsepower motors are permanently lubricated and should not be lubricated after installation. Motors supplied with grease fittings should be greased in accordance with manufacturers’ recommendations. Where motor temperatures do not exceed 104ºF (40ºC), the grease should be replaced after 2,000 hours of running time as a general rule.Wheels require very little attention when moving clean air. Occasionally, oil and dust may accumulate causing imbalance. When this occurs, the wheel and housing should be cleaned to ensure smooth and safe operation.All fasteners should be checked for tightness each time maintenance checks are performed prior to restarting unit.A proper maintenance program will help these unitsdeliver years of dependable service.11. Belt tension can be adjusted by loosening fourfasteners on the drive frame, see Figure 11. The motor plate slides on the slotted adjusting arms and drive frame angles in the same manner.12a. Sizes 071-161: Belts should be tensioned justenough to prevent slippage at full load.Note: Belts should have a slight bow on the slack side while running at full load (see Figure 12a).12b. Sizes 180-540: Belt tension should be adjusted toallow 1⁄64 in. (0.397 mm) of deflection per inch of belt span. For example, a 15 in. (381 mm) belt span should have 15⁄64 in. (0.234 mm) (or about 1⁄4 in. (6 mm)) ofdeflection with moderate thumb pressure at mid-point between pulleys (see Figure 12b).13. The adjustable motor pulley is factory set for theRPM specified. Speed can be increased by closing or decreased by opening the adjustable motor pulley.14. Any increase in speed represents a substantialincrease in the horsepower required by the unit.15. Motor amperage should always be checked to avoidserious damage to the motor when speed is varied.Operation: G / GB1. Before starting up or operating fan, check allfasteners for tightness. In particular, check the setscrews in wheel hub. 2. While in the OFF position or before connecting thefan to power, turn the fan wheel by hand to be sure it is not striking the venturi or any obstacle. 3. Start the fan and shut it off immediately to checkrotation of the wheel with directional arrow in the motor compartment. 4. When the fan is started, observe the operation andcheck for any unusual noises. 5. With the system in full operation and all ductworkattached, measure current input to the motor and compare with the nameplate rating to determine if the motor is operating under safe load conditions. 6. Keep inlets and approaches to fan clean and freefrom obstruction.Belt/Bearing Maintenance GB Unit1. Belts tend to stretch after a period of time.They should be checked periodically for wear and tightness. When replacing belts, use the same type as supplied with the unit. 2. Matched belts should always be used on units withmulti-groove pulleys. 3. For belt replacement, loosen the tensioning deviceenough to allow removal of the belt by hand. 4. Once installed, adjust belts as shown in“Pre-Starting Checks.”5. Shaft bearings can be classified in twogroups: relubricating and non-relubricating. All non-relubricating bearings on model GB fans are factory lubricated and require no further lubrication under normal use (between -20º to 180ºF (-29º to 82ºC) in a relatively clean environment). 6. On GB belt driven fans, the standard cast pillowblock bearings are factory lubricated and are provided with external grease fittings. Annual lubrication is recommended, or more frequently if needed (See Table 2). Do not over-grease. Use only one or two shots of lubricant with a hand gun. Maximum hand gun rating is 40 psi. Rotate bearings during lubrication where good safety practice11. During the first few months of operation, checkbearing setscrews periodically to ensure tightness.12. If unit is to be left idle for an extended period,remove belts and store in a cool, dry place to avoid premature belt failure.Recommended Relubrication Frequency in MonthsNOTE: If unusual environment conditions exist (extreme temperature, moisture or contaminants) more frequent lubrication is required.A good quality lithium base grease, conforming to NLGI Grade 2 consistency, such as those listed here may be used.9Model G/GB Centrifugal Roof Exhaust Fans10Model G/GB Centrifugal Roof Exhaust FansCurb Cap/GB Belt Drive Centrifugal Roof Exhaust FanShaft PulleyBearings11Model G/GB Centrifugal Roof Exhaust Fans12471558 • Model G/GB IOM, Rev. 3, October 2010 Copyright 2010 © Greenheck Fan Corp.Greenheck Catalog G/GB provides additional information describing the equipment, fan performance, available accessories, and specification data.®Phone:(715)359-6171•Fax:(715)355-2399•E-mail:*********************•Website: WarrantyAMCA Publication 410-96, Safety Practices for Users and Installers of Industrial and Commercial Fans, provides additional safety information.
