动力装置的工作原理及常见故障分析

WORKING PRINCIPLE OF HTE POWER UNIT AND FAILURE ANALYSIS

本文通过介绍动力装置的作用及特点,并详细分析柱塞泵及液压阀组在实现液压推靠器推收过程中的工作原理,同时结合近几年在使用过程中遇到的推收故障,对动力装置的装配及使用环境提出新要求,对柱塞泵及液压阀组不断改进,旨在提高液压推靠器在测井过程中的可靠性及安全性。

The paper introduces the functions and features of the power unit. The working principle of plunger pump and hydraulic valve in opening and closing of the hydraulic pusher are analyzed. New requirements for assembling the unit and using environment are proposed based on the faults happened during the usage in recent years.Continuous improvements have been made to the plunger pump and hydraulic valveto improve the reliability and safety of the hydraulic pusher during logging.
