Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The schematic diagram of the scroll compressor with axial air delivery adjustment of the present invention is as follows Figure 1 to Figure 4 shown. Including fixed scroll 1, exhaust pipe 3, exhaust pipe 4, casing 5, suction pipe 8, motor stator 9, motor rotor 10, main shaft 11, machine base 12, Oldham coupling ring 13, rotating scroll 14. Axial air volume adjustment mechanism.

[0019] The main shaft 11 is a crank shaft structure, and an eccentric oil passage is opened in the axial direction of the main shaft. One end of the main shaft 11 with the eccentric oil passage passes through the frame 12 and cooperates with the motor rotor 10. The eccentric crank pin of the main shaft and the rotating scroll 14 The shaft connecting groove on the outside of the chassis cooperates, the motor rotor 10 cooperates with the motor stator 9, and t...

Abstract

The invention provides a scroll compressor with axial displacement regulation in order to meet change requirements in refrigeration or heating demand, which can realize continuous micro regulation, reduce investment and save energy sources. In an axial displacement regulation mechanism, a rotating ring is sleeved outside an exhaust pipe, and the external surface of the rotating ring is provided with a push board slot and a tilted slot with a downward opening; the external surface of an exhaust connecting pipe and the internal surface of a fixed scroll exhaust hole are respectively provided with a guide slot, a butting rod is arranged in the guide slot, one end of the butting rod supports against the tilted edge in the tilted slot, and the other end supports against the fixed scroll; a baffle ring is sleeved outside the butting rod to baffle the butting rod and is fixedly connected with the fixed scroll, and a regulating spring is installed on a connecting face between the fixed scrolland a base; a piston spring is arranged between the piston and a cylinder bottom, one end of a push rod is connected with the piston, and the other end is connected with a push board; and one end of a high-pressure gas connecting pipe is connected with a gas inlet on a cylinder cover, and the other end is connected with the exhaust pipe through a regulating valve. The compressor of the invention realizes axial output displacement regulation and unloading start.

Description

technical field [0001] The invention relates to a scroll compressor with axial air delivery adjustment. Background technique [0002] The excellent performance of the scroll compressor makes it more and more widely used in refrigeration equipment. In order to meet the demand for refrigeration or heating, the air delivery volume provided by the compressor should adapt to the demand for refrigeration or heating load, and reduce energy consumption. The refrigeration compressor is required to have the function of adjusting the output air volume. At present, the method of adjusting the gas delivery volume of the scroll refrigeration compressor has high requirements on the performance of the motor and a large initial investment. With the increasingly tense energy sources, it is urgent to develop more energy-saving and environmentally friendly products with simple structure, convenient control, and investment savings to meet There is an increasing market demand, but there is no te...
