Abstract

The invention discloses a double-stage screw type air compressor which comprises a base. A motor is arranged on the base. The motor is provided with a frequency converter. An air compressor main engine is arranged at one end of the motor. An air filtering mechanism is arranged at the upper end of the air compressor main engine. An oil and gas separator is arranged on one side of the air compressormain engine. The air compressor main engine and the oil and gas separator are connected through an oil and gas mixing pipe. A minimum pressure valve is arranged on the top of the oil and gas separator. A heat exchanger is arranged on one side of the oil and gas separator. The heat exchanger and the minimum pressure valve are connected through an air pipe. The air filtering device comprises a first stage filtering device and a second stage filtering device. The first stage filtering device and the second stage filtering device are connected in series through a pipeline. The second stage filtering device is connected with the air compressor main engine. By arranging the first stage filtering device and the second stage filtering device, the air purification effect is improved, and the stability and the service life of the air compressor operating in a dirty environment are ensured.

Description

technical field [0001] The invention belongs to the technical field of air compressors, in particular to a two-stage screw air compressor. Background technique [0002] Air compressors are now widely used in many fields, and screw air compressors are volumetric compressors, which have the advantages of high reliability, convenient operation, stable power, and strong practicability. At present, air compressors are often used in places with dirty air. The existing air filter devices cannot clean the inhaled air, which shortens the life of the equipment and prolongs the maintenance time, which affects the construction efficiency. Contents of the invention [0003] The invention solves the shortcomings of the prior art and provides a two-stage air filter device, which improves the quality of intake air and ensures the normal service life of the air compressor. [0004] The technical solution adopted in the present invention is: a two-stage screw air compressor, including a ba...
