　　进口不锈钢气动执行器 工作原理 working principle

　　双作用Double acting

　　1.通过向端口B供气，向外部施加压力并向内驱动双活塞，使小齿轮在空气流动时顺时针转动从端口A排出 By supplying airto port B, pressure is applied externally and the double piston is driveninward, causing the pinion to rotate clockwise and discharge from port a as theair flows

　　2.通过向端口A供气，向中央腔室施加压力，迫使双活塞向外移动线性活塞力通过齿条传递到小齿轮，使小齿轮逆时针转动，同时空气从端口B排出By supplying airto Port A, pressure is applied to the center chamber and forces the dualpistons outward Linear piston force is transferred via gear racks to the piniongear, causing the pinion to turn counterclockwise while the air is beingexhausted from Port B

　　弹簧复位，单作用Spring return, single acting

　　1.当空气压力损失时，存储在压缩弹簧迫使活塞向内产生旋转运动，排气从端口A排出。这种“故障保护”该位置由弹簧力保持，直到重新施加气压端口A。Upon loss of airpressure, the stored energy in the compressed springs forces the pistonsinwards producing rotary motion with exhaust air exiting at Port A. This"fail safe" position is held by spring force until air pressurereapplied to Port A.

　　2.通过向端口A供应空气，将压力施加到中央腔室，迫使双活塞向外，将外部腔室中的弹簧压缩至产生逆时针旋转。排气口位于端口B。 By supplying air to Port A, pressure isapplied to the center chamber, forcing the dual pistons outward, compressingthe springs in the outside chambers to produce a counterclockwise rotation.Exhaust air exits at Port B

　　1.输出扭矩选择范围广 Wide selectionrange of output torque

　　CTW共有10种不同的规格尺寸的不锈钢气动执行器供选择，在5bar的情况下，扭矩输出范围为15Nm到3815Nm，其中300执行器的扭矩可达到3815Nm，是目前输出大扭矩的不锈钢气动执行器之一 CTW has 10 different sizes of stainless steelpneumatic actuators to choose from. Under the condition of 5bar, the torqueoutput range is 15nm to 3815nm, of which the torque of 300 actuators can reach3815nm. It is one of the stainless steel pneumatic actuators that output largetorque in the world at present.

　　2.优越的耐蚀性 Superiorcorrosion resistance

　　不锈钢气动执行器的所有金属部件及配件均选用不锈钢材料，其中缸体、端盖和活塞由不锈钢CF8（304）或CF8M（316）精铸而成，此外执行器的齿轮轴以及紧固件选用304SS或316SS不锈钢。不锈钢气动执行器具有十分优良的抗腐蚀性能，是大多数腐蚀性化学物质（如酸、碱），以及腐蚀性的工业环境，如海上作业、石油以及天然气平台、制药和食品行业中的理想选择 Allmetal parts and accessories of the stainless steel pneumatic actuator are madeof stainless steel. The cylinder body, end cover and piston are precision castfrom stainless steel CF8 (304) or CF8M (316). In addition, the gear shaft andfasteners of the actuator are made of 304SS or 316SS stainless steel. Stainlesssteel pneumatic actuator has excellent corrosion resistance, which is the bestchoice for most corrosive chemicals (such as acid and alkali) and corrosiveindustrial environments, such as offshore operations, oil and gas platforms,pharmaceutical and food industries

　　3.运行平稳，使用寿命长 Stable operationand long service life

　　CTW齿轮齿条式执行器运行平稳摩擦系数低，在2-10Bar的气源压力下可轻松实现100万次无故障运行 CTW rack and pinion actuator operatessmoothly with low friction coefficient, and can easily realize 1million troublefree operations under the air supply pressure of 2-10bar

　　4.灵活的行程调节 Flexible strokeadjustment

　　工作行程∶0~90度。行程末端的限位可调，其中A系列可单向调节，调节位置和范围0±5度或90±5度，AA系列可双向调节，调节位置和范围0±5 度和 90±5度 Working stroke:0~90 degrees. The limit at the end of the stroke is adjustable, in which aseries can be adjusted in one direction, with the adjustment position and rangeof 0 ± 5 degrees or 90 ± 5 degrees, and AA series can be adjusted in twodirections, with the adjustment position and range of 0 ± 5 degrees and 90 ± 5degrees.

　　5.适用于NAMUR以及ISO5211安装标准 Applicable toNAMUR and ISO5211 installation standards

　　CTW不锈钢执行器的安装连接尺寸采用国标准设计，可以直接与NAMUR标准的电磁阀，限位开关以及直接安装连接，底部的IS05211标准的阀门安装面能轻松实现与阀门的直接安装 The installation and connection dimension ofCTW stainless steel actuator adopts national standard design, which can bedirectly installed and connected with Namur standard solenoid valve, limitswitch and positioner. The is05211 standard valve installation surface at thebottom can easily realize direct installation with the valve

　　6.单作用执行器采用高性能弹簧 Single actingactuator adopts high-performance spring

　　采用弹筒预压缩结构设计，选用钢琴弹簧钢丝制造生产，不仅弹簧配置灵活，而且能确保单作用不锈钢执行器在失气复位的工矿条件下全扭矩运行20万次以上。Adopting the precompression structure design of the cartridge case and the production ofhigh-quality piano spring steel wire, not only the spring configuration isflexible, but also it can ensure that the single acting stainless steelactuator can operate at full torque for more than 200000 times under theindustrial and mining conditions of gas loss and reset.
