Problems solved by technology

[0002] Compressor cylinders are generally made of solid castings, which are heavy and expensive. There is a draft angle in the inner circle of the blank, resulting in a large machining allowance, large material loss, and high labor costs.
On the other hand, the existence of the sliding vane groove of the cylinder greatly weakens the overall strength of the cylinder, which may lead to poor clearance between the sliding vane and the cylinder when the compressor is running; the cylinder wall is under the action of gas torque and screw torque. , prone to deformation, affecting the centering clearance of the pump body and affecting the performance of the compressor

Abstract

The invention provides a cylinder, a compressor, refrigeration equipment and a production process, and belongs to the technical field of compressors. The cylinder includes: a body; and an extending part which is connected with the body, and a welding seam being arranged between the extending part and the body. According to the technical scheme, the body and the extending part are connected in a welding mode, so that the body and the extending part can be made of steel. Compared with a casting product, the strength of the material of the cylinder formed by welding the steel is improved, and the strength and the rigidity of the cylinder are correspondingly improved. In the running state of the compressor, the condition that the gap between a sliding vane and the cylinder is poor can be improved, the cylinder wall is not prone to deformation due to high strength under the action of gas torque and screw torsion, the influence on a centering gap of a pump body is reduced, and the working performance of the compressor is improved.

Description

technical field [0001] The application belongs to the technical field of compressors, and in particular relates to a cylinder, a compressor, a refrigeration device and a production process. Background technique [0002] The cylinder of the compressor is generally made of solid casting, which is heavy and expensive. There is a draft angle in the inner circle of the blank, which leads to a large machining allowance, large material loss, and high labor costs. On the other hand, the existence of the sliding vane groove of the cylinder greatly weakens the overall strength of the cylinder, which may lead to poor clearance between the sliding vane and the cylinder when the compressor is running; the cylinder wall is under the action of gas torque and screw torque. , prone to deformation, affecting the centering clearance of the pump body and affecting the performance of the compressor. Contents of the invention [0003] Embodiments according to the present application aim to imp...
