compressor and cylinder

Abstract

The invention discloses a compressor and an air cylinder. The compressor comprises a compression mechanism. The compression mechanism comprises the air cylinder, an upper bearing, a lower bearing and a crankshaft. The upper bearing and the lower bearing are arranged on the two end faces of the air cylinder correspondingly. The crankshaft is arranged in the air cylinder in a penetrating mode and supported by the upper bearing and the lower bearing. The crankshaft is provided with an eccentric part which is sleeved with a piston. The air cylinder is made of a metal strip. The metal strip is selected and manufactured into the air cylinder, the weight of the air cylinder can be reduced, and the machining cost of the air cylinder can be lowered. In addition, the metal strip has the characteristics of high strength, high rigidity and high elasticity modulus, deformation of the air cylinder in the assembly process can be avoided further, and changes of the gap of a sliding sheet slot in the operating process of the compressor can be avoided; and accordingly, the strength of the air cylinder can be improved, and the performance of the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and a cylinder. Background technique [0002] The cylinder in the six parts of the rotary compressor pump body is generally made of solid casting, which is heavy and expensive. There is a draft angle in the inner circle of the blank, and there are many machining allowances. It needs rough machining, semi-finishing machining, and finishing machining. Process, processing labor costs are high. On the other hand, the existence of the slide groove of the cylinder weakens the overall strength of the cylinder to a large extent, so that the force of the compressor in the running state easily leads to poor clearance between the slide plate and the cylinder; the cylinder wall is affected by the gas torque and screw torque. Under the environment, it is easy to produce deformation, affect the centering clearance of the pump body, and affect the performance of the compressor...

On the other hand, the existence of the slide groove of the cylinder weakens the overall strength of the cylinder to a large extent, so that the force of the compressor in the running state easily leads to poor clearance between the slide plate and the cylinder; the cylinder wall is affected by the gas torque and screw torque. It is prone to deformation, affecting the centering clearance of the pump body and affecting the performance of the compressor.
