A lot, design except pump itself, in addition to manufacture factor and some and pump use the choosing of related elements (such as shaft coupling, oil filter)
Also there is relation with operation during, trial run and run etc..The operation principle of hydraulic pump is the change that motion brings pump chamber, from
And compression fluid makes fluid have pressure energy.Prerequisite condition is exactly that pump chamber has sealed volume change.
Hydraulic pump can produce the change of temperature when breaking down, and Hydraulic pump fault testing agency structure common at present is answered
Miscellaneous, testing result is not directly perceived enough, causes inefficiency.
Utility model content
The purpose of this utility model is and a kind of Hydraulic pump fault proposed in order to solve shortcoming present in prior art
Testing agency.
