Problems solved by technology

[0003] (1) The first flange 2' and the skirted first muffler 1' cannot be applied to the vertical compressor, which not only has poor versatility, but also increases the variety of materials
[0004] (2) Due to the increase of the first flange 2' ring car process, the process is complicated and the production cost is high

Embodiment 1

[0032] Such as figure 2 As shown, this embodiment proposes a preferred compressor. The compressor is a horizontal compressor, which includes a casing, a compression pump body and a motor arranged in the casing, and the motor consists of a stator fixed in the casing. And the rotor is rotatably arranged in the stator. The crankshaft of the compressor is fixed with the rotor and is driven to rotate by the rotor. The compression pump body is arranged on the left side of the motor. The compression pump body includes a first muffler 1, a first flange 2, a first cylinder 3, a diaphragm 4, a second cylinder 5, and a second flange 6 arranged along the crankshaft in sequence And the second silencer 7. The first flange 2 can seal the upper end of the first cylinder 3, and the second flange 6 can seal the lower end of the second cylinder 5 to avoid refrigerant leakage. The first muffler 1 and the second muffler 7 are used to eliminate the noise generated when the pump body is running.

Embodiment 2

[0039] Such as Figure 4 As shown, this embodiment further proposes a preferred compressor. The structure of the compressor is basically the same as the structure of the compressor described in the first embodiment. The difference is that the setting position of the baffle 8 is different.

[0040] The baffle 8 of this embodiment is sleeved outside the baffle 4, and the baffle 8 is closely connected with the second cylinder 5 to separate the compressor into two left and right cavities, and a gap is formed between the baffle 8 and the casing. Specifically, the inner end surface of the baffle 8 is provided with a positioning protrusion 83, and the second cylinder 5 is provided with a positioning hole 51 in an interference fit with the positioning protrusion 83 at a position opposite to the positioning protrusion 83. The baffle 8 is sleeved on the outside of the baffle 4 and closely fits with the second cylinder 5 through the positioning protrusion 83 and the positioning hole 51. At t...

Embodiment 3

[0043] Such as Figure 5 As shown, this embodiment further proposes a preferred compressor. The structure of the compressor is basically the same as that of the compressor described in the first embodiment. The difference is that the baffle 8 is set at a different position.

[0044] The baffle 8 of this embodiment is sleeved outside the baffle 4, and the baffle 8 is tightly connected with the first cylinder 3 to separate the compressor into two left and right cavities, and a gap is formed between the baffle 8 and the casing. Specifically, the inner end surface of the baffle 8 is provided with a positioning protrusion 83, and the first cylinder 3 is provided with a positioning hole 31 that is in interference fit with the positioning protrusion 83 at a position opposite to the positioning protrusion 83. The baffle 8 is sleeved on the outside of the baffle 4 and closely fits with the first cylinder 3 through the positioning protrusion 83 and the positioning hole 31. At the same time...

Abstract

The invention discloses a compressor, and relates to the technical field of compressors. The compressor comprises a shell, and a compression pump body arranged in the shell; and the compression pump body includes a first silencer, a first flange, a first cylinder, a separation plate, a second cylinder, a second flange and a second silencer arranged along a crankshaft in sequence. The compressor further comprises a baffle plate arranged in the shell for dividing the compressor into left and right two cavities; and a gap is formed between the baffle plate and the shell. The compressor is simple in structure, simplifies the process when providing stable oiling, and reduces the production cost.

Description

Technical field [0001] The present invention relates to the technical field of compressors, in particular to a compressor. Background technique [0002] Such as figure 1 As shown, an existing horizontal compressor includes a compression pump body, which includes a first muffler 1', a first flange 2', a first cylinder 3', and a partition 4'which are sequentially arranged along the crankshaft. , The second cylinder 5', the second flange 6'and the second muffler 7'. This type of horizontal compressor uses the pressure difference to oil the method specifically: using the narrow gap formed between the first muffler 1'with a skirt and the first flange 2'to cause a pressure difference between the left and right cavities of the compressor , That is, the pressure of the cavity on the side of the suction pipe (exhaust port) is less than the pressure of the cavity on the motor side, and finally stable oiling is realized. That is to say, this horizontal compressor needs to add the skirt of...
