Problems solved by technology

[0005] However, the above-mentioned conventional way of testing the compressor needs to be carried out manually no matter the assembly of the pulley 84, the control of the start of each toggle switch 86, 88 or the judgment of the detected pressure value, so not only will the entire test procedure be too time-consuming and consuming Manpower, but also prone to errors due to personnel negligence

Abstract

The invention discloses a pressure measuring unit of a compressor, and the pressure measuring unit is used for driving the compressor to operate so as to carry out pressure measuring operation. The pressure measuring unit is respectively connected with the inlet end and outlet end of the compressor mainly by use of a positive pressure pipeline and a negative pressure pipeline, electromagnetic valves are respectively arranged in the positive pressure pipeline and the negative pressure pipeline, a control module controls the operation of the compressor and the startup time of the electromagnetic valves in the positive pressure pipeline and the negative pressure pipeline, thereby automatically carrying out positive pressure or negative pressure detection operation of the compressor. The pressure measuring unit provided by the invention can automatically carry out the positive pressure or negative pressure detection operation of the compressor, thereby achieving the effects of saving the labour cost, effectively shortening the testing time and greatly improving detection efficiency.

Description

technical field [0001] The invention relates to a pressure measuring device for a compressor, in particular to a pressure measuring device for a compressor which can automatically detect positive and negative pressures of a compressor. Background technique [0002] At present, after the general compressor is assembled, positive and negative pressure tests must be carried out to determine whether the output pressure of the compressor can reach the predetermined pressure value and whether there is any internal pressure leakage in the assembly. [0003] The usual way to detect the compressor is as follows: Figure 8 As shown, the compressor 81 to be tested is first placed on a workbench 82, and a pulley 84 that can be driven by a motor 83 is set on the transmission shaft of the compressor 81, thereby driving the compressor 81 to perform Test operation; when positive pressure detection is desired, one end of a positive pressure pipeline 85 is first connected to the output port 8...
