Embodiment 1

[0029] Such as Figure 1-2 As shown, the present embodiment provides a slide valve adjustment mechanism, which is set in the screw compressor, and adjusts the movement of the slide valve 1 through the force of the electric field to realize loading or unloading of the load in the screw compressor.

[0030] The slide valve adjustment mechanism includes a slide valve 1, a connecting rod 2, a piston 3, and an electric field driving part 5. The electric field driving part 5 includes an electric field generating device, which includes a fixed electrode plate 52 and a movable electrode plate 53, two electrode plates Parallel relative setting;

[0031] The slide valve 1 is connected with one end of the connecting rod 2, the other end of the connecting rod 2 is connected with one end of the piston 3, and the other end of the piston 3 is fixed with the movable electrode plate 51 of the electric field driving part 5;

[0032] When the two plates are charged, a repulsive Coulomb force is...

Embodiment 2

[0045] This embodiment provides a screw compressor, which adopts the adjustment mechanism of the slide valve 1 provided in Embodiment 1.

[0046] Preferably, a compression chamber and a slide valve adjustment chamber are formed in the screw compressor, and the compression chamber and the slide valve adjustment chamber are separated by a partition 9, and the electric field driving part 5 is arranged in the slide valve adjustment chamber in the screw compressor housing, The slide valve 1 is arranged in the compression chamber, one end of the connecting rod 2 is connected with the slide valve 1 , and the other end is connected with the piston 3 through the partition 9 .

[0047] The screw compressor provided in this embodiment changes the way of loading and unloading the slide valve in the prior art, and replaces the oil pressure force with the electric field force between electric charges to push the slide valve 1 to move, the adjustment accuracy is greatly increased, and it is e...

Embodiment 3

[0049] This embodiment provides an air conditioning system, which adopts the slide valve adjustment mechanism provided in Embodiment 1 and / or the screw compressor provided in Embodiment 2. Utilize the interaction force between charges to realize the movement of the slide valve 1 and complete the stepless adjustment of the compressor load, making the adjustment more precise, avoiding the waste of lubricating oil during the adjustment process of the slide valve in the existing screw compressor, and saving energy , the stability is higher, and the response speed of loading and unloading is greatly improved.

[0050] In summary, the present invention provides a slide valve adjustment mechanism and a screw compressor and an air-conditioning system using the same, by setting the slide valve 1, the connecting rod 2, the piston 3 and the electric field drive part 5 in the slide valve adjustment mechanism, wherein the electric field The driving part 5 includes an electric field generat...

Abstract

The invention relates to a slide valve regulation mechanism, and a screw compressor and an air-conditioning system comprising the same. The slide valve regulation mechanism is provided with a slide valve, a connecting rod, a piston and an electric field driving part, wherein the electric field driving part comprises an electric field generation device; the electric field generation device comprises a fixed electrode plate and a movable electrode plate, and the fixed electrode plate and the movable electrode plate are oppositely arranged in parallel; the slide valve is connected with one end ofthe connecting rod, the other end of the connecting rod is connected with one end of the piston, and the other end of the piston is fixed to the movable electrode plate of the electric field drivingpart; when the two electrode plates are charged, repellent coulomb force is formed between the electrode plates; and under the action of the coulomb force, the movable electrode plate drives the piston to move and then drives the slide valve to move, so that the slide valve is adjusted quickly, the regulation precision is greatly improved, and high-efficiency control is easy. The situation that ascrew compressor is frequently loaded and unloaded due to instability of a 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 ...
