Air cylinder assembly with double-spring structure and using method thereof

Abstract

The invention provides an air cylinder assembly with a double-spring structure. The assembly comprises an air cylinder, an air cylinder sliding sheet, a main spring and a sliding sheet resistance reduction assembly, the main spring is placed in a spring groove, the air cylinder sliding sheet is arranged in an air cylinder sliding sheet groove in a sliding manner, and the sliding sheet resistance reduction assembly is arranged at the lower side of the main spring; the sliding sheet resistance reduction assembly is used for offsetting the resistance of the air cylinder sliding sheet compressingthe main spring downwards, a vent hole is formed between the spring groove and an air inlet in a penetrating manner, a cylinder is fixed to the lower side in the spring groove, a ventilation hole is formed at one side of the cylinder and aligned with one end of the vent hole, and the sliding inner side of a sliding cover is arranged at the inner wall side of the cylinder; and a small spring is mounted at the bottom of the sliding cover. By means of the air cylinder assembly, spring resistance borne by part of the air cylinder sliding sheet in the stage from the minimum compression position tothe maximum compression position of the springs can be offset, so that power is reduced, and the energy efficiency of a compressor is improved.

Description

technical field [0001] The invention relates to a cylinder assembly with a double spring structure and an application method thereof, belonging to the technical field of rotary compressors. Background technique [0002] The rotary compressor cylinder is generally driven by the motor through the crankshaft to swing the eccentric roller ring along the inner wall of the cylinder cavity. The sliding vane cooperates with the eccentric roller ring to reciprocate and swing in the sliding vane groove to complete the working cycle of gas suction, compression and discharge. Under the action of the spring force, the sliding plate is in close contact with the outer surface of the eccentric roller ring to form a dynamic seal, which divides the crescent-shaped space between the eccentric roller ring and the inner wall of the cylinder chamber into a low-pressure (suction) chamber and a high-pressure (compression) chamber. cavity. [0003] In the prior art, the resistance of the eccentric ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the resistance of the eccentric roller rotor during the operation of the compressor cylinder pump body from the minimum spring compression position to the maximum spring compression position includes refrigerant load, friction resistance and spring resistance, especially in the compression stage of the spring, the spring compression increase, so the spring resistance increases, which is one of the contributions to the input power of the compressor. Now there is an urgent need for a cylinder assembly with a double spring structure and its use method to solve the above problems
