液压试验台设计

摘要:液压系统的组成、功能日益复杂，因而发生故障的机率也随之增多。液压系统的故障具有隐蔽性、变换性和诱发因素的多元性，所以在故障诊断和排除时，不但需要有熟练的技术人员，同时还要有完善的检测设备。检测液压元件性能参数的试验设备多为性能单一的液压试验台。而且一般为液压件生产厂家和研究所专用。从使用方面来看，一旦液压系统发生故障，常常需检测多种液压元件的技术指标，才能找出故障部位和根源，达到及时修理的目的。本文阐述了一种液压试验台的设计、工作原理及主要技术指标。它综合了液压阀和液压缸专用试验台的性能，达到了一机多用的目的，该试验台具有测试可靠、制造容易、维护方便、成本低廉等特点。

THE DESIGN OF HYDRAULIC TEST BENCH

Abstract:The components and functions of hydraulic system become more and more complex , and thus the probability of failure also increase. Hydraulic system failure with elusive, transformation-induced and inducing factor multiplicity, so in the fault diagnosis and rule out the possibility, not only the need for skilled personnel, but also have a well-developed testing equipment, most of the test equipments that used for detecting the performance parameters of hydraulic components are a single hydraulic test bed. And generally to hydraulic parts manufacturers and research institutes dedicated. From the perspective of using, once the hydraulic system failure, are often required to detect a wide range of hydraulic components of the technical indicators to identify the root causes of fault location and to achieve the purpose of timely repairs. In this paper we explain the design of one kind of hydraulic test bench, working principle and the main technical indicators. It combinated the performance of hydraulic valves and hydraulic cylinders dedicated test-bed, to become multiple use, the test bench with characteristics of test reliable, easy to manufacture, easy maintenance, low cost and so on.

Key words:hydraulic test stand; tank; hydraulic valve; hydraulic cylinder; forcing press
