Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the sliding plate and the roller are not tightly fitted due to the spring falling off in the compressor in the prior art, thereby causing a crosstalk between the compression chamber and the suction chamber. In the case of gas, the defect of the cooling capacity of the compressor is reduced, so as to provide a compressor pump body assembly

Embodiment approach 1

[0028] Such as Figure 1-5 As shown, the present invention provides a compressor pump body assembly, including a crankshaft 1, a cylinder 4, an upper flange 2, a lower flange 5, a roller 7 and a sliding vane 8, and it also includes a (located below the lower flange 5 and sleeved on the tail of the short shaft of the crankshaft 1) and a sheave structure 6 that rotates with the crankshaft 1, the sheave structure 6 corresponds to the sliding plate 8 is provided with a guide groove 62, and the sliding piece 8 protruding from the cylinder along the axial direction of the crankshaft 1 is provided with a device inserted into the guide groove 62 and driven by the guide groove 62 to make the slide piece 8. A guide rod 81 that reciprocates in the cylinder 4.

[0029] By adding a sheave structure at the lower end of the crankshaft, the sheave structure can be rotated together with the crankshaft, and a guide groove is set on it, a guide rod is set on the slide plate and the guide rod is...

Embodiment approach 2

[0040] Such as Figure 6-7 As shown, this embodiment is a corresponding modification made on the basis of Embodiment 1, and the difference from Embodiment 1 is only that the sheave structure 6 is a circular stepped structure whose center protrudes downward. This can effectively ensure that the bending moment of the sliding vane guide rod is small and ensure its reliability, which is an optimized design of the sheave structure.

Abstract

The invention provides a pump body assembly of a compressor. The pump body assembly comprises a crankshaft (1), a rotor (7), an air cylinder (4) and a slip sheet (8), and further comprises a grooved wheel structure (4) which is arranged at the lower end of the crankshaft (1) and rotates with the crankshaft (1), wherein the position, corresponding to the slip sheet (8), on the grooved wheel structure (4) is provided with a guide slot (62); and a guide rod (81), which is inserted into the guide slot (62) and driven by the guide slot (62) for enabling the slip sheet (8) to be in reciprocating motion in the air cylinder (4), is arranged on the slip sheet (8). By virtue of the pump body assembly of the compressor provided by the invention, a novel pump body assembly of the compressor is provided, so that mounting of an original spring is effectively cancelled, and therefore, the occurrence of refrigerating capacity decline of the compressor due to a blow-by phenomenon between a compression cavity and a gas absorption cavity when the compressor slip sheet and a roller are not tightly fitted because of spring dropping is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning, and in particular relates to a pump body assembly of a compressor. Background technique [0002] In the prior art, in order to ensure the normal operation of the rolling rotor compressor, it is necessary to ensure the bonding state between the sliding vanes and the rollers, so as to prevent the low refrigeration capacity of the compressor caused by the cross-gas between the compression chamber and the suction chamber. occur. At present, in the design and production process of the pump body, rolling rotor compressor manufacturers use interference fit to make the pump spring closely match the cylinder spring hole, fix the pump spring in the cylinder spring hole, thereby compressing the sliding vane, so that the sliding vane and the roller Fit to ensure the normal operation of the compressor, but during the actual operation of the compressor, the spring often falls off, c...
