Abstract

Abstract: In order to solve the sealing reliability and selective design problems of the plungers and cylinder liners of oil-water separated plunger pump, a plunger sealing performance experimental device and the loading system were developed to simulate the actual operating conditions of the hydraulic plunger pump, and the dynamic balance design of the experimental device was carried out. The simulation model of the loading system for the experimental device was established, and then a reasonable loading method was determined through simulation and comparison. The loading test and stability test of the experimental device show that the operation of the experimental device is stable and reliable, and the volumetric efficiency is within a reasonable range.

Key words: plunger seal, hydraulic plunger pump, loading system, experimental device

摘要： 为解决油水分离式柱塞泵的柱塞与缸套的密封可靠性及选型设计问题，研制了模拟水压柱塞泵实际运行工况的柱塞密封性能实验装置及其加载系统，并对实验装置进行了动平衡设计。在建立实验装置加载系统的仿真模型后，通过仿真对比确定了合理的加载方式。该实验装置的加载实验和稳定性实验表明，实验装置运行稳定可靠，且容积效率在合理范围内。
