Variable frequency air conditioner compressor and pipeline vibration testing system and method thereof

Abstract

The invention relates to an air conditioner compressor and pipeline vibration testing technology. At present, a maximum value of compressor and pipeline system vibration when a variable frequency air conditioner is started, operated and stopped can not be effectively tested so that a variable frequency air conditioner pipeline system vibration level is difficult to accurately evaluated, and phenomena of misjudgement, missed sanction and the like are easy to generate. In order to solve the above problems, the invention provides a variable frequency air conditioner compressor and pipeline vibration testing system. The system comprises a compressor to be tested, a pipeline fixedly connected to the compressor, a vibration testing automation control apparatus, a first vibration sensor module, a second vibration sensor module, a vibration signal acquisition front end and a computer vibration signal automation processing apparatus. The vibration testing automation control apparatus is used to make a variable frequency compressor carry out repeated point-by-point frequency sweeping operation and starting and stopping operation so as to effectively test a vibration maximum value of the compressor and the pipeline. The system and the method have advantages that a testing process is automatic and testing efficiency is increased.

Description

technical field [0001] The invention relates to frequency conversion air conditioner technology, in particular to the technology of frequency conversion air conditioner compressor and pipeline vibration testing system. Background technique [0002] In the production or testing process of air-conditioning products, it is necessary to carry out vibration testing and objective evaluation on the piping system of outdoor units. It is necessary to test the maximum vibration value of the piping system of the compressor under the conditions of start-up, operation and shutdown of the inverter air conditioner, but there is currently no such An effective testing system for pipeline vibration of inverter air conditioner. In order to accurately evaluate the vibration level of the pipeline system of the inverter air conditioner and avoid misjudgments and missed judgments, how to more accurately test the maximum value of the vibration of the compressor pipeline system of the inverter air c...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a vibration testing system and method for the compressor and piping of an inverter air conditioner, which solves the problem that the maximum value of the vibration of the compressor and piping system cannot be effectively tested at present when the inverter air conditioner is in the state of starting, running and stopping, resulting in It is difficult to accurately evaluate the vibration level of the pipeline system of the inverter air conditioner, and it is prone to problems such as misjudgment and missed judgment
