The Designs of the Function and Structure of the New Hydraulic Cylinder Test-Bed

摘要

A new hydraulic test-bed of cylinder was designed and manufactured, which can perform hydraulic cylinder type test, factory test and the ultrahigh pressure test with 70Mpa. In addition, six hydraulic cylinders can be tested at the same time, and also the test-bed can simultaneously complete three types of test which are the routine test, high temperature test and ultrahigh pressure test. Besides, the new test-bed can achieve goals which are stepless and remote pressure control, multiple speed adjustment, proportional loading, automatic oil discharge, automatic control of oil temperature, noncontact measurement of hydraulic cylinder's stroke, and intelligent control of hydraulic system. In this paper, the performance and structure of the test-bed and the functions of hydraulic control system were described.
