1, minimum starting pressure is tested:
Under drive unit immunization with gD DNA vaccine, adjustment bleed pressure/hydraulic power source pressure of starting from scratch makes it slow increase, starts to hydraulic cylinder, and till angular transducer changes, record pressure peak now, is minimum starting pressure.
2, power output and push-pull effort is tested:

Suggestion setting 2 kinds of methods can be optional by operator, can need to choose suitable method according to operator like this.
3, resistance to pressure is tested:
Subjects is hydraulic cylinder, and method is established standards pressure, the standard dwell time, and setting maximum leakage amount, primer fluid potential source is forced into normal pressure, starts pressurize.
, hydraulic cylinder No leakage or within leakage rate (≤), and reach the dwell time, then automatically unloading, test is passed through.
(2), hydraulic cylinder leakage rate is greater than maximum leakage amount, and not to the dwell time, then automatically unloading, termination test.
(3), duration of test can consider that additive method detects leakage rate.
4, sealing is tested:
, hydraulic cylinder sealing, with the test of above-mentioned hydraulic cylinder resistance to pressure, be distinguished as test pressure difference.
, housing seal, test(ing) medium is gas, and pressure release is manual pressure release, and other try with reference to above-mentioned resistance to pressure side.
5, permanance and durability test is tested:
Setup parameter before experiment: nominal load; adjusted by topworks's frock or connect valve and load; stroke range (angular displacement; adjustable), journey time (adjustable), action frequency (can record; switch is once respectively a durability test); reach set action number of times, be considered as product qualified, auto stop also points out experiment to terminate.
