Embodiment approach 1

[0028] Such as figure 1 , figure 2 As shown, this embodiment provides an oil baffle 4 , including an oil baffle body 1 , a flange 2 is provided on one side of the oil baffle body 1 , and a blade structure 3 is provided on the flange 2 .

[0029] The oil baffle plate 4 is installed on the end of the motor rotor 5, especially suitable for being installed on the top of the motor rotor 5. It rotates at a high speed under the drive of the motor rotor 5, so that the radial direction of the motor rotor 5 forms a negative pressure chamber and accelerates the air flow. The rotating flow of the high-pressure gas, the refrigerated oil in the high-pressure gas is separated under the action of the centrifugal force, which reduces the oil content of the compressor exhaust, especially the cooperation of the flanging 2 and the blade structure 3 can increase the speed of the air rotation.

[0030] In this embodiment, the cross section of the blade structure 3 is arc-shaped. The arc-shaped b...

Embodiment approach 2

[0037] refer to image 3 , In this embodiment, another specific structure of the blade structure is provided. The blade structure 3 includes two folded edges arranged at an angle to each other. The two folded edges are respectively the first folded edge 8 and the second folded edge 9, wherein the length of the first folded edge 8 is greater than the length of the second folded edge 9, and the first folded edge 8 is a wind receiving surface. By using the longer folded edge as the wind-receiving surface, the contact area between the blade structure 3 and the airflow can be increased, and the wind resistance can also be effectively reduced.

[0038] In this embodiment, except that the specific shape of the blade structure 3 is different from that of the first embodiment, other structures and connections are the same as those of the first embodiment.

[0039] It should be noted that the specific structure of the blade structure 3 and the number of installations can be adjusted ac...

Abstract

The invention relates to the technical field of compressors, in particular to an oil baffle plate and a compressor adopting the same. The oil baffle plate comprises an oil baffle plate body, wherein a flange is arranged on one side of the oil baffle plate body; and a blade structure is arranged on the flange. Meanwhile, the invention further provides the compressor adopting the oil baffle plate. The oil baffle plate, provided by the invention, is driven by a motor rotor to rotate at a high speed, so that a negative-pressure cavity is formed in the radial direction of the motor rotor, the rotary flowing of air is accelerated, refrigerant oil in high-pressure gas is separated out under the effect of centrifugal force, the exhaust oil content of the compressor is reduced, in particular, the air rotating speed can be accelerated through matching between the flange and the blade structure, and the oil-gas separation effect is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil baffle and a compressor using the same. Background technique [0002] The compressor usually includes a closed shell, a compression pump body, a motor assembly, a crankshaft, a gas-liquid separator, a suction pipe and an exhaust pipe. The stator and rotor form the motor assembly of the compressor, and the compression pump body includes a cylinder, an upper flange, a lower flange and a roller fixed on the eccentric part of the crankshaft. When working, the rotor rotates inside the stator, and drives the rollers to roll eccentrically in the cylinder through the crankshaft. Under the action of the eccentric rolling of the rollers, the low-pressure refrigerant is sucked into the cylinder through the suction pipe and compressed until it reaches the pressure Only when the critical pressure is exceeded is it output to the heat exchange system through the exhaust pipe.
