Problems solved by technology

However, the gas sealing width between the inner diameter of the center hole of the intermediate partition plate and the outer diameter of the piston is relatively small in this structure, and it is not easy to seal. As a result, high-pressure gas leaks from the inner diameter of the piston to the inner diameter of the cylinder, directly reducing the work of the compressor. efficiency

Abstract

A rotary compressor, including a motor assembly and a compression assembly arranged in the compressor casing, the compression assembly includes two or more cylinders, a piston respectively arranged in each cylinder and a piston arranged in the slide groove of the cylinder Sliding vane, with two or more eccentric parts, eccentric crankshaft driving the piston movement, the compressor is connected with the valve device; the first sliding vane chamber of the first cylinder in the compressor is connected to the first pressure switching tube, and the second cylinder’s The second vane chamber is connected to the second pressure switch tube; the first pressure switch tube and the second pressure switch tube are respectively connected to the valve device, and the other end of the low pressure tube connected to the valve device is connected to the low pressure part of the compressor One end of the high-pressure pipe connected to the valve device and the other end connected to the high-pressure part of the compressor housing; the first and / or second pressure switching pipe accommodates one end of the slide spring. The invention has the characteristics of good sealing performance, low gas leakage rate, high working efficiency and wide application range.

Description

technical field [0001] The present invention relates to a rotary compressor. Background technique [0002] The rotary compressor is mainly composed of an eccentric crankshaft, a piston and a cylinder. The size and relative relationship of each component in the compressor shell is directly related to the leakage of the high-pressure gas inside from the high-pressure chamber to the low-pressure chamber. [0003] The intermediate partition of the existing rotary compressor is arranged between the two eccentric parts of the eccentric crankshaft, and its central aperture must be larger than the outer diameter of the eccentric part, otherwise, the intermediate partition cannot be installed between the two eccentric parts. However, the gas sealing width between the inner diameter of the center hole of the intermediate partition and the outer diameter of the piston is relatively small in this structure, and it is not easy to seal. As a result, high-pressure gas leaks from the inner ...
