Lubrication gear pump safety valve setting

Shenzhen ZF HYDRAULIC production of lubrication gear pump, lubrication gear pump is a low pressure gear pump. Part of the lubrication gear pump itself with a safety valve, the safety valve mainly plays a role in safety protection, because the structure is simple, open pressure is not accurate, large pulsation, can not be used as a precise safety valve. The setting of the safety valve full open pressure of the lubricating gear pump is generally as follows:

 

1, the rated pressure of lubrication gear pump is less than 0.6mpa, the safety valve opening pressure is rated pressure plus 0.25.

 

2, lubrication gear pump rated pressure is greater than or equal to 0.6MPa, the safety valve open pressure is 1.5 times the rated pressure.\
