Description

Technical Field

[0001] The invention belongs to the technical field related to air compressors, and in particular relates to a screw-type twin compressor. Background Art

[0002] A twin-screw air compressor generally includes a compressor head fixed in a housing, an oil-gas cylinder connected to the exhaust port of the compressor head, an oil separator core fixed inside the oil-gas cylinder, an oil filter connected to the oil outlet of the oil-gas cylinder, and a radiator fixed between the oil filter and the compressor head. When the machine is running, the external air is compressed by the compressor head and mixed with the lubricating oil in the head to form an oil-gas mixture, which is then discharged into the oil-gas cylinder through the exhaust port of the head; under the action of the oil-gas cylinder, the oil-gas mixture is separated into compressed gas containing a small amount of oil and liquid lubricating oil. The compressed gas is filtered twice by the oil separator core inside the oil-gas cylinder and then discharged into the gas storage tank to supply gas to the factory, while the lubricating oil is filtered twice by the oil filter and cooled by the radiator before flowing back to the head.
