液壓試驗(yàn)臺(tái)設(shè)計(jì)
摘要:液壓系統(tǒng)的組成、功能日益復(fù)雜，因而發(fā)生故障的機(jī)率也隨之增多。液壓系統(tǒng)的故障具有隱蔽性、變換性和誘發(fā)因素的多元性，所以在故障診斷和排除時(shí)，不但需要有熟練的技術(shù)人員，同時(shí)還要有完善的檢測(cè)設(shè)備。檢測(cè)液壓元件性能參數(shù)的試驗(yàn)設(shè)備多為性能單一的液壓試驗(yàn)臺(tái)。而且一般為液壓件生產(chǎn)廠家和研究所專用。從使用方面來(lái)看，一旦液壓系統(tǒng)發(fā)生故障，常常需檢測(cè)多種液壓元件的技術(shù)指標(biāo)，才能找出故障部位和根源，達(dá)到及時(shí)修理的目的。本文闡述了一種液壓試驗(yàn)臺(tái)的設(shè)計(jì)、工作原理及主要技術(shù)指標(biāo)。它綜合了液壓閥和液壓缸專用試驗(yàn)臺(tái)的性能，達(dá)到了一機(jī)多用的目的，該試驗(yàn)臺(tái)具有測(cè)試可靠、制造容易、維護(hù)方便、成本低廉等特點(diǎn)。

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.
