HAWE比例調(diào)壓閥技術(shù)特性，哈威比例調(diào)壓閥材質(zhì)壽命
Pressure regulator can be said that the basic pressure relief valve, the working principle of the valve as follows:
High-pressure medium through a small hole into a relatively large cavity to achieve decompression,
In fact, by blocking the pressure, the diaphragm or piston on both sides of the mouth is the outlet,
主要作為執(zhí)行機(jī)構(gòu)的預(yù)調(diào)節(jié)閥,可達(dá)19bar 
此壓差＝PA-PR,并與比例電磁鐵的電流成比例變化.
通過(guò)出口A處的壓力PA可以操縱液壓執(zhí)行機(jī)構(gòu),并可實(shí)現(xiàn)對(duì)對(duì)變量泵,比例閥等的無(wú)級(jí)調(diào)節(jié).
比例電磁鐵的功率需求非常低,
樣本D78817/1,D7831/1或D7835中的EV型放大器以及D7845 FF 中的PLVC型可編程總線控制器可以作為控制裝置。
P口處允許進(jìn)口壓力(系統(tǒng)壓力)被限制在40bar,在較高壓力情況下,
為避免慣性時(shí)間后的調(diào)節(jié)不準(zhǔn)確以及切換跳躍,需將壓力預(yù)先降低至PP＝40bar。

 單閥訂貨實(shí)例;PM11-7-B0,6-G24/1
閥組訂貨實(shí)例;PMZ1A51-11/1-11/1-1-G24
One side is man-made pressure, and control the size of the stem and the diaphragm (piston) connected,
So as long as a fixed pressure, then the pressure of the outlet chamber will always be equal to this pressure,
This given pressure can be provided by a spring or air source or hydraulic source.
壓力差Pmax=19 bar
流量Qmax=2 lpm
概述
PM和PMZ型調(diào)壓閥為鋼制直動(dòng)式調(diào)壓閥,由閥體,調(diào)節(jié)閥心,閥套和比例電磁鐵構(gòu)成。
 它能將由P口處進(jìn)入的不穩(wěn)定的系統(tǒng)壓力在閥出口A處降低為一個(gè)較低的,恒定的壓力差。
調(diào)壓閥基本可以說(shuō)是減壓閥，減壓閥的工作原理如下：
高壓介質(zhì)通過(guò)一個(gè)小孔充到一個(gè)相對(duì)較大的腔里實(shí)現(xiàn)減壓，
This differential pressure = PA-PR,
and with the proportional electromagnet current proportional change.
The pressure PA at the outlet A can be operated by the hydraulic actuator and
the stepless adjustment of the variable pump, proportional valve, etc. can be achieved.
Proportional electromagnet power requirements are very low,
