Problems solved by technology

The horizontal pump body is installed horizontally and horizontally. When the compressor is subjected to a strong longitudinal impact Fg, the inertial impact load of the cylinder overcomes the friction force Ff generated by the screw compression, and the original relative position between the cylinder and the upper and lower bearings will change, that is, the outer diameter of the roller is 341mm. Clearance fit with cylinder bore 331 becomes interference causing compressor to seize

Embodiment Construction

[0042] see in conjunction Figure 1 to Figure 16 As shown, according to the embodiment of the present invention, the pump body assembly includes a cylinder 3 and a first bearing 1 and a second bearing 2 arranged at both ends of the cylinder 3, the cylinder 3 and the first bearing 1 are integrally formed; and / or, the cylinder 3 It is integrally formed with the second bearing 2.

[0043] When the cylinder 3 and the first bearing 1 are integrally formed, there is no fit gap between the cylinder 3 and the first bearing 1 as a whole, so that the cylinder 3 and the first bearing 1 can be eliminated under the strong impact load of the pump body. Compressor jamming caused by relative displacement; when the cylinder 3 and the second bearing 2 are integrally formed, the cylinder 3 and the second bearing 2 can be formed as a whole without a fit gap, so the pump body can be eliminated. Under a strong impact load, the relative displacement between the cylinder 3 and the second bearing 2 c...

Abstract

The invention provides a pump body assembly, a casting die and a rotating compressor. The pump body assembly comprises an air cylinder (3), a first bearing (1) and a second bearing (2), wherein the first bearing (1) and the second bearing (2) are arranged at the two ends of the air cylinder (3). The air cylinder (3) and the first bearing (1) are integrally formed; and / or the air cylinder (3) and the second bearing (2) are integrally formed. According to the pump body assembly, changing of the relative positions of the air cylinder and the bearings can be effectively prevented, and the phenomenon that the compressor is stuck is avoided.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a pump body assembly, a casting mold and a rotary compressor. Background technique [0002] At present, horizontal rotary compressors are mostly used in household refrigerators, freezers, commercial refrigeration, and refrigeration equipment; they can also be used in room air conditioners and vehicle air conditioners, and can be used in a wide range of applications. [0003] The horizontal rotary compressor takes up less space in the height direction, which can greatly reduce the overall height of the unit, and has more advantages in application space. At the same time, the compressor is installed horizontally, with a low center of gravity and small vibration amplitude, which reduces the risk of vibration cracking of the piping of the unit, and the noise of the whole machine is small, which improves the reliability and experience of the product. [0004] like fi...
