The warranty period of the product is 1 year in service or 1.5 years after the product is delivered, whichever is first.Also, the product may have specified durability, running distance or replacement parts. Please consult your nearest sales branch.2. For any failure or damage reported within the warranty period which is clearly our responsibility,a replacement product or necessary parts will be provided.This limited warranty applies only to our product independently, and not to any other damage incurred due to the failure of the product.3. Prior to using SMC products, please read and understand the warranty terms and disclaimersnoted in the specified catalog for the particular products.Compliance Requirements1. The use of SMC products with production equipment for the manufacture of weapons of massdestruction(WMD) or any other weapon is strictly prohibited.2. The exports of SMC products or technology from one country to another are governed by therelevant security laws and regulation of the countries involved in the transaction. Prior to the shipment of a SMC product to another country, assure that all local rules governing that export are known and followed.CautionSMC products are not intended for use as instruments for legal metrology.Measurement instruments that SMC manufactures or sells have not been qualified by type approval tests relevant to the metrology (measurement) laws of each country.Therefore, SMC products cannot be used for business or certification ordained by the metrology (measurement) laws of each country.2. Specific Product PrecautionsWarning(1) Confirm the specifications.Do not operate at pressures, temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction. (Refer to the specifications.)Please contact SMC when using a fluid other than compressed air (including vacuum).We do not guarantee against any damage if the product is used outside of the specifications range.(2)Products mentioned in this catalog are not designed for use as stop valves with zero air leakage.A certain amount of leakage is allowed in the products specifications. Tightening the needle to reduce leakage to zero may result in equipment damage.(3)Do not disassemble the product or make anymodifications, including additional machining.Doing so may cause human injury and/or an accident.(4)The flow rate characteristics for eachproduct are representative values.The flow rate characteristics are characteristics of each individual product. Actual values may differ depending on the piping, circuitry, pressure conditions, etc. Also, depending on product specifications, there may be variations in the zero needle rotations position of the flow rate characteristics.(5)Check if that PTFE can be used in application.PTFE powder (Polytetrafluoroethylene resin) is included in the seal material for piping taper thread of male thread type. Confirm that the use of it will not cause any adverse effect on the system.Please contact SMC if the Safety Data Sheet (SDS) is required.Warning(1) Operation ManualInstall the products and operate it only after reading the operation manual carefully and understanding its contents. Also, keep the manual where it can be referred to as necessary.Warning(2)Ensure sufficient space for maintenance activities.When installing the products, allow access for maintenance.(3)Confirm that the lock nut is tightened.A loose lock nut may cause speed changes in the actuator.(4)Check the degree of rotation of the needlevalve.The Products in this catalog are retainer type so that the needle is not removed completely. Over rotation will cause damage.(5)Do not use tools such as pliers to rotate theknob.This can cause idle rotation of the knob or damage.(6) Confirm the air flow direction.Mounting backward is dangerous, because the speed adjustment needle will not work and the actuator may lurch suddenly.(7) Adjust the needle by opening the needle slowly after having closed it completely.Loose needle valves may cause unexpected sudden actuator lurching.When a needle valve is turned clockwise, it is closed and cylinder speed decreases. When a needle valve is turned counterclockwise, it is open and cylinder speed increases.(8)Do not apply excessive force or shock to the body or fittings with an impact tool. This can cause damage or air leakage.(9)Tighten threads with the proper tightening torque.When installing the products, follow the listed proper torque.(10)For installation/removal, please tighten the hexagonal width across flats of Body B (AS1400-M3: joint) with an appropriate spanner.Do not apply torque at other points as the product may be damaged. For AS22*0～AS42*0, the Body A can be rotated after installation.Design/ SelectionMountingMountingCaution(1) Tightening methodThe proper tightening torques of the fitting are as shown in the table below. As a guide, tighten by hand, then turn it two or three turns with a wrench. Pay attention not to over tighten the product. Check the dimensions of each product for the hexagon width across flats.(2)The proper tightening torques for hexagonlock nuts are shown in the table below. For standard installation, turn 15 to 30゜using a tool after fastening by hand.Pay attention not to over tighten the product. Check the dimensions for each product for the width across flats.Caution(1)Refer to the Fittings & Tubing Precautions for handing One-touch fittings.(2) Preparation before pipingBefore piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe.(3)Winding of sealant tapeWhen screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealing material do not get inside the pipe. Also, when the sealant tape is used, leave approx. 1 thread ridges exposed at the end of the threads.Warning(1) Type of fluidsPlease consult with SMC when using the product in applications other than compressed air.(2) When there is a large amount of drainage Compressed air containing a large amount of drainage can cause the malfunction of pneumatic equipment. An air dryer or water separator should be installed upstream from filters.(3) Drain flushingIf condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow and allow the condensation to enter the compressed air lines. This causes the malfunction of pneumatic equipment.If the drain bowl is difficult to check and remove, the installation of a drain bowl with an auto drain option is recommended.For compressed air quality, refer to SMC catalog "Compressed Air Purification System".(4) Use clean airDo not use compressed air that contains chemicals, synthetic oils that include organic solvents, salt, corrosive gases, etc., as it can cause damage or malfunction.Caution(1) Install an air filter.Install an air filter upstream near the valve. Select an air filter with a filtration size of 5μm or smaller.(2)Take measures to ensure air quality, such as by installing an aftercooler, air dryer, or water separator.Compressed air that contains a large amount of drainage can cause the malfunction of pneumatic equipment, such as flow control equipment. Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air dryer, or water separator.(3) Ensure that the fluid and ambient temperatures are within the specified range. If the fluid temperature is 5℃ or less, the moisture in the circuit could freeze, causing damage to the seals or leading to equipment malfunction. Therefore, take appropriate measures to prevent freezing.For compressed air quality, refer to SMC catalog "Compressed Air Purification System".Air SupplyPiping MountingOperating environmentWarning(1) Do not use in an atmosphere containing corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these.Refer to each construction drawing for information on the materials of flow control equipment.(2) Do not expose the product to direct sunlightfor an extended period of time.(3) Do not use in a place subject to heavy vibration and/or shock.(4) Do not mount the product in locations where it is exposed to radiant heat.MaintenanceWarning(1)Perform maintenance and inspection according to the procedures indicated in the operation manual.If handled improperly, malfunction or damage of machinery and equipment may occur.(2) Maintenance workIf handled improperly, compressed air can be dangerous.Assembly, handling, repair and element replacement of pneumatic systems should be performed by a knowledgeable and experienced person.(3) Drain flushingRemove drainage from air filters regularly. (4) Removal of equipment, andsupply/exhaust of compressed airBefore components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc.Then, Cut the supply pressure and electric power, and exhaust all compressed air from the system using the residual pressure release function.When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent sudden movement.3.

不锈钢网常见规格及技术参数

不锈钢丝网常用丝号、丝径对照表不锈钢网常见规格及技术参数:不锈钢丝网目数、丝径、孔径互算公式：目数＝25.4÷（孔径mm+丝径mm)孔径mm＝25.4÷目数-丝径mm丝径mm＝25.4÷目数-孔径mm什么叫目数目数和毫米属于不同的量纲，所以直接比较没有意义。

“目数”是丝网的规格单位，是指1 英寸（25.4毫米）的长度上，有多少个孔目。

而毫米就是一个简单的长度单位。

由于丝网制作有相应的技术标准，不同大小的目数的丝网有规定的金属丝的直径，所以简单的说出不同目数的丝网，每一个孔不算金属丝的实际毫米数，不是行业内的人，是说不出来的。

目前国际上通用的是泰勒标准筛，所谓的多少目是指在每英寸（一个规定的单位长度 2.54厘米）的长度上有多少筛孔，如果有100个孔，就是100目筛，孔数越多，孔眼也就越小。

但由于制作材料不同，比如有不锈钢筛、尼龙筛、铜筛等，它们的粗细不同，所以同是100目筛地话，大小实际上也有区别什么叫丝径1毫米＝100 丝（道）“丝”是机械工人对0.01 毫米的俗称，有上海技术传承的工人说“丝”，在北方就把0.01 毫米说成“道”的多，这两种说法在行业内都明白。

丝也叫道,不是单位制中的丝米。

习惯上所称的丝即忽米,1丝=0.01毫米=0.00001米=10微米什么是开孔率开孔率是指筛面的有效面积，也就是指筛面上筛孔的面积总和与筛面总面积的比值，开孔率越高，处理能力越大，筛分效率越高。

线径－－就是线材的直径；经线－－所有的纵向编织线；纬线－－所有的横向编织线；目数－－1英寸长度内网孔的个数；密度－－1厘米长度内网孔的个数网孔－－两经丝或两纬丝之间的距离公差－－综平角时，综片处的经线与公差线的垂直距离（MM）公线－－过前后胸果（罗拉）的连线上公差－－综平时综片处的经线高于公差线下公差－－低于公差线叫下公差零公差－－与公差线重合叫零公差综角－－综框开口后，上综与下综的距离平角－－（变角时间）－－综平时，钢筘距长纬点的距离各种丝网的网重及成本计算公式不锈钢网计算公式：网重KG =1/2×丝径×丝径×目数×长×宽价格核算=1/2×丝径×丝径×目数×长×宽×丝价+工时费+流通费电焊网重量计算公式：1寸*1寸丝径*丝径*宽*长÷2=KG1寸*1/2 丝径*丝径*宽*长÷4*3=KG1/2*1/2 丝径*丝径*宽*长=KG1/3*1/3 丝径*丝径*宽*长*3*0.48=KG1/4*1/4 丝径*丝径*宽*长*2= KG3/4*3/4 丝径*丝径*宽*长÷3*2=KG3/8*3/8 丝径*丝径*宽*长*1.35=KG5/8*5/8 丝径*丝径*宽*长÷5*8÷2=KG2寸*4寸丝径*丝径*宽*长÷4*0.75=KG铜网重量计算公式：丝径*丝径*目数*宽*长÷2*1.07=KG席形网计算公式：纬丝径*纬丝径*纬目数*宽*长÷4+经丝径*经丝径*经目数*长*宽÷4=KG轧花网重量计算公式：2.54÷（丝径+孔径）=目数然后按照不锈钢网的计算方式计算，另外加2%~5%~9%弯曲度既为重量床面网的计算方法：平米重（kg）=丝径×丝径×(穿条根数×螺距)成本(元)=平米重×长×宽×丝价+穿条价脚踏网的计算方法：每块网重=丝径×丝径×(2.54÷孔径) ×6.28+边米长×0.35 (此公式为保守算法)养猪网计算方法：平米重（kg）=1/4×丝径×丝径×[25.4÷（长孔+丝径）+25.4÷（宽孔+丝径）]烧烤网计算方法：销售价：筛网价+铁皮边价（一般为1元）+加工费+流通费输送带网计算方法：平米重（kg）=丝径×丝径×[25.4÷（1/2螺距+丝径）] ÷4×125%+穿条重（注：此算法为保守算法）石油震动筛网计算方法：不锈钢网价+塑料平网价+压边费造纸网计算方法：网重（kg）=1/2 ×丝径×丝径×目数×长×矿筛网价格计算方法：（背宽+0.6）2×[2.54÷（缝+背）] ×0.25=重量×丝价+各种费用黑丝布成本计算方法：1/2×丝径×丝径×目数×丝价+工时费+流通费分样筛成本计算方法：网价（筛底）+框价+盖价+各种费用铁窗纱计算方法：网重（kg）=1/2×丝径×丝径×目数×长×宽成本（元）=网重×丝价+工时费+流通费铝合金窗纱计算方法：网重（kg）=1/2×丝径×丝径×目数×0.3×长×宽成本（元）=网重×丝价+工时费+流通费塑料窗纱计算方法：网重（kg）=丝径×丝径×目数×长×宽÷2÷6。
