3rd, engineering machinery engine is opened, hydraulic pump is started to work.
4th, the feedback kind and pressure pumped according to engineering machinery hydraulic, regulation relief valve open ball valve.Observation feedback oil
Road pressure gauge adjusts pressure reducing valve, sets hydraulic pump feedback pressure, hydraulic pump discharge is made to reach maximum pump discharge, is checked on flowmeter
Flow value, check hydraulic pump flow it is whether normal.
5th, working connection pressure gauge is observed, regulation relief valve pressure checks whether prexxure of the hydraulic pump output is normal.
Above example is to elaborate the basic principle and characteristic of the utility model, and the utility model is not by above-mentioned implementation
Example limitation, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes, these
Changes and modifications are both fallen in claimed the scope of the utility model.The utility model requires protection scope is by appended right
Claim and its equivalent thereof.
