Compressor test bench control system and control method

Abstract

The invention provides a compressor test bed control system. The control system comprises a PLC, a test bed pump pressure cover control module for controlling opening or closing of a test bed pump pressure cover according to instructions of the PLC, a segmented air pressure control device for segmented inflation or pressure maintenance or pressure relief of a tested compressor according to the instructions of the PLC, a compressor pressure detecting device for detecting and outputting testing data in the pressure detecting process of the detected compressor, a report generation module for receiving the testing data output by the compressor pressure detecting device and generating testing reports according to the testing data for storage, and a database generation module for generating databases and storing a serial number of the detected compressor and corresponding testing reports. The control system can automatically finish segmented pressure maintenance testing flow of the compressor, automatically generates the testing reports, and stores the testing reports in the databases.

Description

technical field [0001] The invention relates to an automatic control technology of a test system, in particular to a control system and a control method of a compressor test bench. Background technique [0002] At present, the control system of a company's YLC CO2 compressor test bench uses switches, buttons, intermediate relays, time relays, mechanical pressure gauges, etc. to control segmental pressurization: 0~48Bar, 48~96Bar, 96~129Bar, 129~138Bar , each stage of pressurization is selected by the selection button; before the start of pressurization, the on-site operator manually records the start detection time and pressure; The pressure time is controlled by a time relay; after the pressure holding is completed, the operator manually records the end time of the pressure holding and the end pressure of the holding pressure; manually fills in the pressure difference according to the recorded data, and judges whether the pressure difference is less than 3.5Bar and fills in...

AI Technical Summary

Problems solved by technology

[0003] The on-site operators of this control system need to manually select pressurization, pressure holding and data recording, which leads to low production efficiency, and there are loopholes of falsification in manual filling of data sheets (unqualified products are filled in with qualified products, and qualified data sheets are filled directly without testing, etc. ), which brings a lot of inconvenience to the production management of the enterprise; it is inconvenient to save the paper data sheet, which is not conducive to data comparison, summary and archiving; Only qualified signals can be used for test run detection) Since it is sent manually, only qualified signals can be sent but the corresponding barcode cannot be sent, and there is a certain randomness in sending signals, which will bring a lot of inconvenience to the subsequent test system
