Precautions for china Hydraulic Stacked One-Way Valve
Field practice has proved that China Hydraulic Stacked One-Way Valve is prone to problems during use and maintenance. The following are the precautions.
Field practice has proved that China Hydraulic Stacked One-Way Valve is prone to problems during use and maintenance. The following are the precautions.
(1) It is necessary to ensure that the China Hydraulic Stacked One-Way Valve has sufficient control pressure, and it is absolutely not allowed to lose control pressure. Attention should be paid to whether the control pressure meets the requirements for reverse opening. If the control of China Hydraulic Stacked One-Way Valve is introduced from the main system, it is necessary to analyze the influence of the change of main system pressure on the pressure of the control oil circuit, so as to avoid the malfunction of China Hydraulic Stacked One-Way Valve.
(2) According to the position of China Hydraulic Stacked One-Way Valve in the hydraulic system or the size of fluid flow resistance (back pressure) behind the reverse oil outlet cavity, the structure of China Hydraulic Stacked One-Way Valve (simple or double) should be reasonably selected ) and oil leakage method (internal leakage or external leakage). For the internal leakage type china Hydraulic Stacked One-Way Valve, when the reverse oil outlet pressure exceeds a certain value, the hydraulic control part will lose control, so the internal leakage type china Hydraulic Stacked One-Way Valve is generally used for reverse outlet The oil chamber has no back pressure or the back pressure is small; while the external leakage type china Hydraulic Stacked One-Way Valve can be used in the occasion where the back pressure of the reverse oil outlet chamber is high, so as to reduce the minimum control pressure and save control power. If the system adopts the internal unloading type, the plunger cylinder will drop intermittently to generate vibration and noise.
