An oil-cooled compressor with a flexible connection pipeline and its detection method

Abstract

The invention discloses an oil-cooled compressor with a flexible connection pipeline, which includes a flexible connection pipeline connected to the oil-cooled compressor. The flexible connection pipeline includes several pipelines and a flexible connection assembly for pipeline connection. The flexible connection assembly includes a flexible connection ring and a fixed pipe sleeved on the flexible connection ring, elastic flanges are provided at both ends of the flexible connection ring radially inward, and the fixed pipe includes a left half body and a The right half body, there is a gap between the left half body and the right half body, and the wedge-shaped blocks matched by the inclined plane are connected to the left half-body and the right half-body, and the position of the wedge-shaped block is adjusted to change the left half body. The adjustment assembly for the distance between the half body and the right half body, the two ends of the fixed pipe are provided with annular step surfaces that conflict with the ends of the flexible connecting ring, and the annular step surfaces are respectively arranged on the left half body and the right half body, Several pressure detection pieces are provided along the circumferential direction on the annular step surface.

Description

technical field [0001] The invention relates to an oil-cooled compressor with a flexible connection pipeline and a detection 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 co...

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 performance, reducing the overall reliability of the product, and it is difficult to detect oil leakage in time
