供应油研液控单向阀参数,YUKEN选用方法
Site practice has proved that the hydraulic control check valve in
the use of maintenance process prone to problems, the following is a note.
现场实践证明，液控单向阀在使用维修过程中容易出现问题，以下是注意事项。
必须保证液控单向阀有足够的控制压力，**不允许控制压力失压。
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.
应注意控制压力是否满足反向开启的要求。如果液控单向阀的控制引自主系统时，
则要分析主系统压力的变化对控制油路压力的影响，以免出现液控单向阀的误动作。
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,
液控单向阀在液压系统中的位置或反向出油腔后的液流阻力（背压）大小，
合理选择液控单向阀的结构（简式或复式）及泄油方式（内泄或外泄）。
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
对于内泄式液控单向阀来说，当反向油出口压力超过一定值时，
液控部分将失去控制作用，故内泄式液控单向阀一般用于反向出油腔无背压或背压较小的场合；
