Oil-cooled compressor with multiple pipelines and control method

Abstract

The invention discloses an oil-cooled compressor with multiple pipelines and a control method. The oil-cooled compressor comprises a body and an oil cooling mechanism connected to the body. The oil cooling mechanism comprises at least two pipelines and flexible connecting assemblies for connecting the pipelines. Control valves are arranged on the pipelines. The flexible connecting assemblies comprise flexible connecting rings and fixing rings sleeving the flexible connecting rings. At least one clamping groove is formed in each of the two ends of the flexible connecting rings, elastic sealingrings are arranged in the clamping grooves in a cooperating manner, each fixing ring is composed of two spliced fixing semi-rings, elastic parts abut against the portions between the fixing semi-rings, and pressure detection parts are arranged in the elastic parts. The oil-cooled compressor further comprises a control module for receiving and recording pressure values of the pressure detection parts, and the control module controls switching on and off of the control valves.

Description

technical field [0001] The invention relates to an oil-cooled compressor with multiple pipelines and a control method. Background technique [0002] Compressors mainly provide raw power for industrial production, including air compressors, process compressors, refrigerant compressors, etc., which are used in industrial automation, traffic braking, energy chemical industry, refrigeration and air conditioning, etc., and are indispensable for modern industry equipment. The compressor will generate a lot of heat during operation. To ensure normal operation, a heat dissipation structure is required. Taking the screw compressor as an example, the screw compressor has air-cooled, water-cooled, oil-cooled and other structural forms. [0003] Due to the more uniform heat dissipation and high efficiency of oil cooling, oil cooling is mostly used when the operating environment temperature is high and the power is high. However, since the oil cooling structure directly contacts the com...

Problems solved by technology

[0003] Due to the more uniform heat dissipation and high efficiency of oil cooling, oil cooling is mostly used when the operating environment temperature is high and the power is high. However, since the oil cooling structure directly contacts the compressor, vibration will be transmitted, and the compressor will Larger vibrations will be generated, that is, the connecting pipes on the oil cooling heat dissipation structure will generate larger vibrations, which will make the compressor and the casing have larger noises, and the vibration will increase the possibility of oil leakage at the connection of the pipelines After the oil spill, the safety hazard cannot be found in time and the compressor cannot work normally, which greatly reduces the production efficiency
