基于流量特性的刹车系统卸压迟缓机理分析与研究

Analysis and Research on pressure relief delay mechanism of brake system based on flow characteristics

摘要

某产品在开展刹车系统调试工作过程中，出现了刹车压力下降慢的故障问题。为精准定位该故障的根源，本文通过设计并实施主系统管路上各关键附件回油流量的测量对比试验，全面且深入地分析了影响刹车压力下降慢的主要因素。针对性地制定了安装前系统清洗的具体要求以及初调试验的科学方法，为从根本上杜绝后续同类故障的发生提供了可靠的技术保障，也为该产品相关系统的故障排查与质量管控积累了宝贵经验。

Abstract

During the commissioning of the brake system of a product, the problem of slow brake pressure drop occurred. In order to accurately locate the root cause of the fault, this paper designs and implements the measurement and comparison test of the return oil flow of key accessories on the main system pipeline, and comprehensively and deeply analyzes the main factors affecting the slow decline of brake pressure. The specific requirements for system cleaning before installation and the scientific method of preliminary commissioning test were formulated, which provided reliable technical support for fundamentally eliminating the occurrence of similar subsequent failures, and also accumulated valuable experience for the troubleshooting and quality control of the product related systems.
