Mud is a common type or plunger-type piston, driven by the motive power of the crankshaft rotary pump, crankshaft driven through the crosshead and then the plunger in the pump cylinder piston or reciprocating motion to do.

常用的 泥浆泵是活塞式或柱塞式的﹐由动力机带动泵的曲轴回转﹐曲轴通过十字头再带动活塞或柱塞在泵缸中做往復运动。

When plunger running, for the centrifugal inertial force brought by crankshaft and impact inertial force generated by repeated running of plunger piston, the high power vibration and noise appear.

柱塞泵在运转过程中，主要由于曲轴产生离心惯性力和柱塞来回运动产生惯性冲击力，会产生较大的振动和噪声。

In the present work,Cu nanoparticles with an average size of 20-50 nm were dispersed in diesel fuel oil . A injection pump plunger was in-situ repaired on a 12PSDB75 fuel injection pump by applying auto-reconditioning function of Cu nanoparticles. Mophologies and typicle element distributions of the plunger piston surface before and after repair were analyzed by scanning electron microscopy and energy dispersive X-ray spectroscopy.
