角行程氣動執行機構選型

 

氣動執行機構的選用Selection of pneumatic operation organ

 

 

類型:雙作用氣動執行器

要考慮安全系數,建議在正常扭矩上增加20% - 30%余量。

例如:這個閥門的扭矩需要l00Nm.則考慮安全系數的扭

矩應該是100 ( 1+30%) =130Nm,假如氣源壓力=0.5MPa,

根據上面的選型表,可以選擇這個最小型號為C110DA。

TypeDouble acting pneumatic actuator

To consider the safety factor,It is recommended torque on

the normal increase of 20% - 30% margin.
For example: This valve torque needs l00Nm. Then consider the safety factor of the torsional
Moment should be 100 (1 +30%) = 130Nm, if the gas supply pressure = 0.5MPa ,
Based on the above selection table, Ican choose the smallest model C110DA

單動作Single action :
輸出力矩有兩種There are two kinds of output torque ;
第一、壓縮空氣壓縮彈簧后所得。在這種情況下,氣源壓力推動活塞所產生的力減去彈簧壓縮后產生的反作用力,輸出力矩則從起點的最大值,逐漸遞減直至90°為最小值。
First,it is gained by compressing the spring resulting from compressing air.In such condition ,force created by pressure of air supply forcing pistons subtracts created by compressed spring,and output torque descends gradually from max.of jumping-off till 90°which is minimum.
第二;當失氣時彈簧的恢復力所得。在這種情況下,由于彈簧的逐漸伸長,輸出力矩從90°時的最大值,,遞減到0°時的最小值。
Second,it is gained by resting force of spring when air exhausts.In such condition,because of gradual elongation of spring,output torque descends from max.of 90°to minimum of 0°.
例;閥門力矩=80N.m; 可靠系數; (20%);氣源壓力=0.4Mpa

執行機構力矩=80×1.2=96N.m
查表,在0.4Mpa壓力下,被選用的單作用執行機構是C140SRK7
在氣源壓力的作用下,最小扭矩135N.m
彈簧復位時,最小扭矩;95.9N.m

 

 

彈簧Spring

氣壓Air pressure

For example; valve moment =80N.m
Confidence coefficient (20%)
Pressure of air supply =0.4Mpa
Torque of operation organ =80×1.2=96N.m
Refer to list,the selected single action operation organ is C140 SR K7
while under air source pressure,minimum torque is 135N.m
when the spring resets,minimum torque is 95.9N.m
