Problems solved by technology

However, the compressor in the prior art has large errors in oil pressure adjustment when the slide valve is adjusted; there is leakage in the oil circuit that pushes the slide valve to move, and the oil pressure in the oil piston cavity is unstable; oil pressure adjustment requires response time; The cleanliness of the road is not high, and the stuck action of the loading valve body fails, which leads to the problems of insufficient adjustment accuracy of the compressor, poor stability when the load is loaded, and long response time of the adjustment process.

Abstract

The invention relates to a slide valve adjustment mechanism and a screw compressor and an air-conditioning system using the same. The slide valve adjustment mechanism is provided with a slide valve, a connecting rod, a piston and an electric field driving part, wherein the electric field driving part includes an electric field generating device, an electric field The generating device includes a fixed electrode plate and a movable electrode plate, and the two electrode plates are arranged parallel to each other; the slide valve is connected to one end of the connecting rod, the other end of the connecting rod is connected to one end of the piston, and the other end of the piston is connected to the movable part of the electric field driving part. The electrode plates are fixed together; when the two plates are charged, a repulsive Coulomb force is formed between the plates. Under the action of the Coulomb force, the movable electrode plate drives the piston to move, and then drives the slide valve to move, realizing the rapid adjustment of the slide valve , the adjustment accuracy is greatly increased, it is easy to control efficiently, and the problem of frequent loading and unloading of the screw compressor caused by the unstable slide valve is avoided.

Description

technical field [0001] The invention relates to an adjusting mechanism, a compressor using the same, and an air-conditioning system, in particular to a sliding valve adjusting mechanism, a screw compressor using the same, and an air-conditioning system. Background technique [0002] With the development of air-conditioning technology, twin-screw compressors have been widely used in the field of commercial air-conditioning. However, the energy adjustment reliability of the fixed-frequency screw compressor is still a technical problem. The fixed-frequency screw compressor has problems such as insufficient adjustment accuracy, poor stability when the load is loaded, and long response time during the adjustment process. The adjustment is unstable, and the compressor cannot run stably under the set load, which affects the reliability of the entire air conditioning unit. [0003] At present, the energy adjustment method of the compressor is mainly through the oil in the oil tank ...
