Abstract

The invention relates to a proportional valve and servo valve testing table. The table comprises an oil tank and a test valve group, wherein the oil tank is provided with an oil outlet pipe. The oil outlet pipe from the oil tank to the test valve group is sequentially provided with an oil pump, an oil filter, a pressure gage and an energy accumulator; the test valve group comprises a flow measuring device, a first three-way ball valve, a second three-way valve and a two-way ball valve; the three ports of the first three-way ball valve are separately connected with an oil outlet of the oil outlet pipe, one of the end of the flow measuring device, and an oil inlet of an oil return pipe; the three ports of the second three-way ball valve are separately connected with an oil outlet of the oiloutlet pipe, the other end of the flow measuring device and the oil inlet of the oil return pipe; the joint of the first three-way ball valve and the oil return pipe is arranged above the two-way ballvalve; and the oil outlet of the oil return pipe is connected with the oil tank. According to the table, most of the hydraulic oil in the testing process is supplied by the energy accumulator, so that the motor capacity is greatly reduced, and the problem of equipment noise is also completely solved.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a test bench for a proportional valve and a servo valve. Background technique [0002] In line with the needs of industrial control automation and intelligence, hydraulic proportional valves and servo valves, as key components of hydraulic automation and intelligence, are more and more widely used in the industrial field. How to effectively and quickly test proportional valves and servo valves and how to save energy , Improving production efficiency and reducing costs are particularly important and urgent. [0003] The traditional proportional valve and servo valve test bench test methods have the following problems: serious energy consumption, high noise, and serious heat generation. Contents of the invention [0004] In order to solve the above problems, the object of the present invention is to provide a test bench for proportional valves and servo valves. [0...
