Exhaust pipe and exhaust cavity assembly for rotor compressor

Abstract

The invention discloses an exhaust pipe and exhaust cavity assembly for a rotor compressor. An exhaust cavity comprises a first end cover and a second end cover which are fixedly connected, wherein a partition plate is fixed between the first end cover and the second end cover; a first cavity is formed by a space formed by the partition plate and the first end cover; a second cavity is formed by a space formed by the partition plate and the second end cover; a plurality of air inlet pipes are connected between the partition plate and the second end cover in a penetrating mode and communicated with the first cavity and the outside of the exhaust cavity; a plurality of vent holes are further formed in the partition plate; the air inlet end of the exhaust pipe penetrates through the first end cover and the partition plate; the air inlet end of the exhaust pipe is located in the second cavity; and the exhaust pipe is connected with a shell of the compressor in a penetrating mode. According to the exhaust pipe and exhaust cavity assembly, the operation exhaust noise of the compressor can be reduced, and the oil injection of the compressor can be reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to an exhaust pipe and an exhaust chamber assembly for a rotor compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The rotary compressor is one of the compressors. The rotary compressor is divided into two types, one is the fixed vane type, and the other is the sliding vane type. The rotor of the stator type rotary compressor is installed on the eccentric shaft, and the volume changes when it rotates, and the cylinder is separated by the stator. A v...

Problems solved by technology

[0003] With the improvement of living standards, people have higher and higher requirements for the use of compressors. Loud noise and compressor oil injection are the most difficult problems in the existing compressor technology, and the exhaust noise is the main noise source of the compressor. One of them, and the oil injection problem will cause the refrigeration system to not cool, the pipes will be blocked or even completely scrapped

[0004] China (CN111706510A) discloses a new rotor compressor with flexible connection and direct suction, which includes a casing, and a pump body is installed inside the casing through a plurality of elastic supports, and the pump body includes a cylinder assembly. A crankshaft is sleeved on the cylinder assembly, and a motor is sleeved above the crankshaft; the pump body also includes a swing or sliding rotor arranged in the cylinder assembly, and the rotor is sleeved with the crankshaft; the rotor The slide plate is connected with the cylinder assembly, and the rotor and the slide plate divide the inner cavity of the cylinder assembly into a low-pressure chamber and a high-pressure chamber; the low-pressure chamber is connected with a suction muffler chamber through an air intake passage, so The suction muffler chamber is connected to the shell suction pipe through a suction flexible connecting pipe; the high pressure chamber is connected to the exhaust muffler chamber through an exhaust passage, and the exhaust muffler chamber communicates with the inner cavity of the casing; Although there is a muffler, its specific structural plan has not been announced, nor has an exhaust cavity been set at the exhaust pipe in the casing to reduce noise and prevent fuel injection
