Guarantee, but cylinder body 4a and oil distribution casing 5a is not rigid connection after all, and since cylinder body 4a is with respect to oil distribution casing 5a high speed rotation fortune
It moves, the high pressure oil in rotary course in plunger hole 11a is simultaneously non-constant, but a continually changing process, adds cylinder body
The factors such as the machining accuracy error of 4a and oil distribution casing 5a influence, and often will appear showing for cylinder body 4a and oil distribution casing 5a offset disengagement
As this has resulted in plunger pump or piston motor volumetric efficiency reduces or even operational failure, the event of cylinder body oil distribution casing damage
Barrier.
