在上篇本文《選用兩臺品質的空油壓機，須得特別注意怎樣基本概念呢? 》，以及為同學們說明了怎樣購選空液壓機。但是選用單臺比較好的空壓力機 除本來產品及高質量(liang)關鍵因(yin)素外，還須得提前準備下文這3個枝(zhi)術性能。

挑(tiao)選空油壓機要特別留意的(de)3個高(gao)性能指(zhi)標設置：輸出水壓pc、吸氣的(de)流量qc、電機功率(lv)P。

1、空壓差(cha)機的讀取壓差(cha)pc

pc=p+∑△p

pc：空液(ye)壓(ya)機的打印(yin)輸出壓(ya)力值(zhi)

p：油路(lu)分配(pei)器(qi)來執行部件的是(shi)最高(gao)的在使用阻力(li)

∑△p：自動程(cheng)序的總重壓消耗。

通常狀態下(xia)狀態下(xia)，另∑△p=0.15~0.2MPa。

2、空油(you)壓機的(de)誤吸視頻流(liu)量qc

不(bu)設氣罐，qb=qmax

設氣罐，qb=qsa

qb：氣動體系(xi)體系(xi)提拱的流量數據

qmax：手(shou)動程序(xu)的極限耗氣量

qsa：液(ye)壓軟件系(xi)統的(de)平均的(de)耗氣(qi)量

空液壓機的吸氣數據流量，qc=kqb

qc：空液(ye)壓機(ji)的吸取到(dao)用(yong)戶流量

k：較正常數。主要來考慮手動(dong)元器件封裝、管插頭等處(chu)的漏損、手動(dong)系統耗(hao)氣量(liang)的估價偏差、數臺手動(dong)裝備有所差異時(shi)運(yun)行的根據率甚(shen)至展(zhan)現出新的手動(dong)裝備的已經性等基本(ben)要素(su)。大部分k=1.5~2.0.

3、空液壓機(ji)的電機(ji)功率P

p=(n+1)*k*p1*qc*(pc/p1)^{[(k-1)/[(n+1)*k]-1}/(k-1)*0.06
