Embodiment

[0038] A diaphragm compressor automatic start-stop control system, which can realize one-key start and one-key stop, without manual operation of various valves, saving manpower and ensuring the efficient and stable operation of the system. In addition, the operation of the system designed according to the present invention can ensure that the inside of the compressor system always maintains a micro-positive pressure state, preventing seal failure and causing leakage; in the pre-operation stage of startup, the compressor can be in an no-load state, reducing the motor inrush current , to ensure the stable operation of the equipment and greatly improve the success rate of startup; the system is equipped with a bypass circuit, and the function of adjusting the compressor flow can be realized with the PLC control circuit.

[0039] Specifically, see figure 1 , A diaphragm compressor automatic start-stop control system designed by the present invention includes: a pneumatic ball valv...

Abstract

The invention relates to the technical field of diaphragm compressors, in particular to a fully automatic start-stop control system for diaphragm compressors. An automatic start-stop control system for a diaphragm compressor, comprising an intake pipeline, an interstage pipeline, and an exhaust pipeline; the intake pipeline and the exhaust pipeline are respectively connected with the intake end and the exhaust end of the diaphragm compressor , the interstage pipeline is set between the air chambers of the diaphragm compressors, and the diaphragm compressor is provided with oil spill pipelines at all levels; oil spill valves are set on the oil spill pipelines to ensure that the oil pressure in the oil chamber does not exceed the set value . The invention can realize the automatic control of the start and stop of the diaphragm compressor, and solve the problem that the control process of the diaphragm compressor is complicated and needs on-site manual control. At the same time, the system can also realize the micro-positive pressure protection of the gas circuit system to prevent the seals from failing due to negative pressure during the start-up phase, resulting in gas leakage; after the shutdown and unloading, the micro-positive pressure can prevent air leakage and compressed gas (such as hydrogen gas) ) to avoid safety accidents.

Description

technical field [0001] The invention relates to the technical field of diaphragm compressors, in particular to a fully automatic start-stop control system for diaphragm compressors. Background technique [0002] Diaphragm compressor is a special positive displacement compressor, which has the characteristics of good sealing performance, wide pressure range, large compression ratio, and no pollution of the compression medium. high-purity gases, precious rare gases, toxic and harmful gases and corrosive gases. [0003] The control of diaphragm compressors is relatively complicated. At present, most sites require manual operation of equipment. For multi-stage diaphragm compressors, two or more personnel are required to operate the equipment at the same time, which wastes manpower and material resources and cannot meet the requirements of automatic production control. In addition, most diaphragm compressors do not have professional operators on site, and it is easy to cause the...
