Problems solved by technology

[0002] When installing the stator of the current rotor compressor, it is necessary to heat the shell and perform thermal sleeve. After the thermal sleeve, the coaxiality of the stator and the shell and the pump body is not easy to ensure, which will affect the performance of the compressor to a certain extent. reduce the efficiency of the compressor
In addition, most ordinary rotor compressors are usually welded on the cylinder or the upper cylinder head. The heat of welding causes thermal deformation, which also has a certain impact on the coaxiality of the compressor, resulting in uneven gaps between the stator and rotor.

Embodiment 1

[0017] Such as figure 1 As shown, the structure of the rotor compressor with uniform stator and rotor clearance includes upper casing cover 1, stator 2, rotor 3, crankshaft 4, integrated frame 5, cylinder 6, piston 7, lower cylinder cover 8, lower casing The cover 9, the air intake connecting pipe 10, and the integrated frame 5 are formed by one-time casting by metal materials, such as cast iron (FC250). The upper part of the integrated frame 5 is connected and fixed with the upper shell cover 1 by laser welding, and the lower part is connected and fixed with the lower shell cover 9. The top of the integrated frame 5 is provided with an inner concave platform 11, and the inner concave platform 11 An inner concave platform plane 111 is provided, and the lower end of the stator 2 is fixedly connected to the inner concave platform plane 111 by bolts.

[0018] Due to the integrated processing of the upper cylinder head and the housing, the two are combined into an integrated fram...

Embodiment 2

[0020] see figure 1 , a rotor-type compressor structure with a uniform stator-rotor gap, wherein the upper part of the integrated frame 5 is connected and fixed with the upper casing cover 1 by adhesive, and its lower part is connected and fixed with the lower casing cover 9 by adhesive, and the lower end of the stator 2 The adhesive connection is fixed on the inner concave platform plane 111, and the rest of the structure is the same as that of Embodiment 1.

Abstract

The invention relates to a rotary compressor structure with an uniform stator and rotor clearance, which comprises a cover of an upper casing, a stator, a rotor, a crankshaft, a casing body, an upper cylinder cover, a cylinder, a piston, a lower cylinder cover, a cover of a lower casing and an air inlet connecting pipe; the upper cylinder cover and the casing body combine two into one, and enable one shot forming to an one-piece frame, an inner concave platform is provided at the top of the one-piece frame, an inner concave platform plane is provided with the inner concave platform, the lower part of the stator is fixed on the inner concave platform plane. Compared with the prior art, the rotary compressor structure has the advantages of uniform stator and rotor clearance, good coaxiality between coaxial parts and the like.

Description

technical field [0001] The invention relates to a rotor compressor, in particular to a rotor compressor structure with uniform stator and rotor gaps. Background technique [0002] When installing the stator of the current rotor compressor, it is necessary to heat the shell and perform thermal sleeve. After the thermal sleeve, the coaxiality of the stator and the shell and the pump body is not easy to ensure, which will affect the performance of the compressor to a certain extent. This reduces the efficiency of the compressor. In addition, most ordinary rotor compressors are usually welded on the cylinder or the upper cylinder head. The heat of welding causes thermal deformation, which also has a certain impact on the coaxiality of the compressor, resulting in uneven gaps between the stator and rotor. Contents of the invention [0003] The object of the present invention is to provide a rotor compressor structure with good coaxiality between the stator and the rotor and un...
