Comprehensive Hydraulic tester for repairing or manufacturing pump/motor/ cylinder,

It tests hydraulic pumps (open, closed, double open pump), hydraulic motors (high speed) , and auxiliary test hydraulic cylinders and valves.

II. , Test Items:

1, displacement test: no-load pressure, discharge measurement.

2, volume efficiency test: the volume measurement efficiency under rated operating conditions,

3, power test: start power, rated power, overload power.

4, overload test: maximum displacement of hydraulic pump or motor (high speed), nominal speed, rated pressure of 110% or the maximum pressure of running for 1 minutes or less.

5, torque test: input torque of hydraulic pump, shaft end torque of hydraulic motor (reverse test)

6, external leakage test: in the above test, check the leakage. of the sealing parts.

7, Auxiliary test for hydraulic valve and hydraulic cylinder, etc..
