Abstract

The invention discloses a double-screw air compressor, which includes: a compressor head, which is in connection with an air filter through an gas inflow control valve; an oil-gas separator, which is connected to the compressor head through a gas delivery pipe, and outputs compressed air through a minimum pressure valve; a first oil return pipeline, which includes a temperature control valve and an oil filter, and connects the oil-gas separator with a compression cavity of the compressor head; a second oil return pipeline, which comprises a filter and a throttling hole, and connects the oil-gas separator with a bearing cavity of compressor head; and a pneumatic control system, which forms a loop with the gas inflow control valve through a pressure regulating valve, the gas inlet front end of the pressure regulating valve is in connection with the oil-gas separator. With a good cooling effect and low noise, the double-screw air compressor has great power, geographical adaptability, and is economical and reliable. Finally, the load matching characteristic of a drilling machine is greatly optimized.

Description

technical field [0001] The invention relates to a power mechanical device, in particular to a twin-screw air compressor used in a complete set of drilling rigs. Background technique [0002] With the development of industry, compressors are used more and more. The twin-screw air compressor for complete drilling rig is a kind of mechanical equipment specially used for drilling rig. Compared with general screw compressors, twin-screw air compressors for complete sets of drilling rigs must not only meet the air supply volume and pressure, but also need to consider that the compressor is dedicated to supporting the drilling rig. Its power source and transmission The device and its control unit are provided by the drilling rig. The compressor should be easily installed and connected to the drilling rig. However, the working conditions of the drilling rig are relatively complicated. It is required that the air volume adjustment system of the compressor can automatically adjust th...
