Embodiment Construction

[0033] Hereinafter, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. According to these detailed descriptions, those skilled in the art can clearly understand the present application and can implement the present application. Without departing from the principle of the present application, the features in different embodiments can be combined to obtain new implementations, or some features in certain embodiments can be replaced to obtain other preferred implementations.

[0034] Diaphragm monitoring: Under normal working conditions and the cleanliness of the compressed gas, the service life of the metal diaphragm is about 3000 to 5000 hours. The greater life is achieved in continuous operation (24 hours), and the lower life is achieved in intermittent operation. The movement state and life of the diaphragm directly affect the working efficiency and service life of the diaphragm compressor. The diaphragm is...

Abstract

The invention belongs to the technical field of compressors, and particularly relates to a fault diagnosis instrument for a diaphragm compressor. An existing compressor fault monitoring device cannotcomprehensively monitor a diaphragm compressor and cannot timely obtain the operating parameters of the diaphragm compressor to perform health monitoring and fault diagnosis on the diaphragm compressor. The fault diagnosis instrument for the diaphragm compressor comprises a fault monitoring module, a signal acquisition module, a data processing module, a display interaction module and a power supply module which are sequentially connected. The fault monitoring module is connected with the power supply module, the signal acquisition module is connected with the power supply module, the data processing module is connected with the power supply module, and the display interaction module is connected with the power supply module. Operation state monitoring and fault diagnosis of the diaphragmcompressor are achieved.

Description

technical field [0001] The application belongs to the technical field of compressors, in particular to a diaphragm compressor fault diagnosis instrument. Background technique [0002] Diaphragm compressor is a special equipment for gas compression with no leakage in the compression cavity. Because of its good sealing performance, wide pressure range and large compression ratio, it is widely used in hydrogen refueling stations and petrochemical fields to compress and transport various high-purity gases, precious and rare gases, toxic and harmful gases and corrosive gases. . The diaphragm is the core component of the diaphragm compressor. The piston pushes the working oil in the oil chamber of the cylinder, and then pushes the diaphragm to reciprocate in the diaphragm chamber to change the working volume of the air chamber. With the cooperation of the suction and exhaust valves To achieve a leak-free periodic work process. In high-pressure compression diaphragm compressors,...
