Problems solved by technology

Existing equipment using manual operation has low precision, and the pressure often exceeds the standard pressure requirements by a lot when the operator stops pressurizing, and the accuracy of the test results is poor; when using the existing test equipment for testing, the test personnel need to observe the whole process, Check for leaks, manual records, human subjectivity is strong, and there will be errors in the test results obtained by different test personnel; the existing test equipment is to manually record the test data and judge the test results, and manually fill in the test results. For the test The accuracy of the judgment of the results is poor; when the equipment is manually controlled, the test process requires the test personnel to observe the whole process, which takes up more test personnel

Abstract

The invention discloses a radar hydraulic cylinder air-tightness test method comprising a step of constructing an air-tightness test control device, a step of emptying a tested hydraulic cylinder and connecting the tested hydraulic cylinder to the air-tightness test control device, a step of putting the tested hydraulic cylinder in a water tank and injecting water into the tank, and a step of pressurizing the tested hydraulic cylinder through a gas path unit and observing the result. The beneficial effect lies in that pressure data can be collected and recorded automatically, the accuracy of test data is improved, the test process can be observed remotely, and the test time is reduced for test personnel.

Description

technical field [0001] The invention belongs to the technical field of airtight hydraulic testing of packaging containers, and relates to a method for testing the airtightness of a radar hydraulic cylinder. Background technique [0002] Whether there are cracks in the hydraulic oil storage container of a certain type of radar is related to the reliable operation of the radar equipment. The air tightness test is used to check whether the air tightness is good, so as to judge whether it has cracks. As the radar hydraulic oil storage container hydraulic cylinder airtight test equipment, the existing equipment is manually controlled, and the test data reading records rely on human sensory visual readings, and finally write the test report by hand, and make the test conclusion. Existing equipment using manual operation has low precision, and the pressure often exceeds the standard pressure requirements by a lot when the operator stops pressurizing, and the accuracy of the test re...
