供應(yīng)油研液控單向閥參數(shù),YUKEN選用方法
Site practice has proved that the hydraulic control check valve in
the use of maintenance process prone to problems, the following is a note.
現(xiàn)場實(shí)踐證明，液控單向閥在使用維修過程中容易出現(xiàn)問題，以下是注意事項(xiàng)。
必須保證液控單向閥有足夠的控制壓力，**不允許控制壓力失壓。
The hydraulic control part will lose control effect,
so the inside of the hydraulic control check valve is generally used for
reverse the oil chamber without back pressure or back pressure smaller occasions;
And the leak-type hydraulic control check valve can be used to reverse
the oil chamber back pressure higher occasions to reduce the minimum control pressure,
Save control power. If the system is used in the unloading type,
the plunger cylinder will intermittently descend to produce vibration and noise.
應(yīng)注意控制壓力是否滿足反向開啟的要求。如果液控單向閥的控制引自主系統(tǒng)時(shí)，
則要分析主系統(tǒng)壓力的變化對控制油路壓力的影響，以免出現(xiàn)液控單向閥的誤動(dòng)作。
the oil after the flow resistance (back pressure) size,
Reasonable choice of hydraulic control check valve structure (simple or double) and t
he way of drainage (internal leakage or leakage).
For the open-type hydraulic control check valve,
when the reverse oil outlet pressure exceeds a certain value,
液控單向閥在液壓系統(tǒng)中的位置或反向出油腔后的液流阻力（背壓）大小，
合理選擇液控單向閥的結(jié)構(gòu)（簡式或復(fù)式）及泄油方式（內(nèi)泄或外泄）。
the requirements for reverse opening. If the control of the hydraulic check valve is drawn from the main system,
It is necessary to analyze the main system pressure changes in the control of
the impact of oil pressure, in order to avoid the hydraulic control check valve malfunction.
Hydraulic control check valve in the hydraulic system position or reverse
對于內(nèi)泄式液控單向閥來說，當(dāng)反向油出口壓力超過一定值時(shí)，
液控部分將失去控制作用，故內(nèi)泄式液控單向閥一般用于反向出油腔無背壓或背壓較小的場合；
