Problems solved by technology

Due to the limitation of its installation structure, the muffler on the compression assembly is canceled, which easily causes the deterioration of the noise of the compressor
At the same time, in the manufacturing process of the horizontal rotary compressor, the installation of the elastic snap ring and the internal gas guide mechanism must be completed before the rotor and the compression assembly are installed in the heat sleeve, which causes the horizontal rotary compressor to be unable to match the vertical rotary compressor. Compressors are fully shared on the same production line for production, resulting in an increase in manufacturing costs

Abstract

An internal gas guide mechanism for a horizontal rotary compressor comprises a shell consisting of a left shell, a main shell and a right shell; a motor assembly and a compression assembly are arranged in the shell; the motor assembly comprises a stator and a rotor; the compression assembly comprises a cylinder, a crankshaft connected with the motor assembly, a piston which is connected with the crankshaft, does eccentric rotation and is arranged in the cylinder, and a slip sheet of which the front end is pressed to the external circle of the piston; a main bearing and a secondary bearing for supporting the crankshaft are arranged on the upper and lower end faces of the cylinder; and the internal gas guide mechanism is arranged between the motor assembly and the cylinder, and is characterized in that the main bearing is provided with a muffler, the inside diameter of one end of the internal gas guide mechanism is connected with the outside diameter of a flange of the main bearing, and the muffler is arranged in a chamber enclosed by the internal gas guide mechanism, the main bearing, the stator and the rotor together. The internal gas guide mechanism of the horizontal rotary compressor has the characteristics of simple and reasonable structure, flexible operation, low manufacturing cost, convenient installation, high production efficiency and good reliability.

Description

technical field [0001] The invention relates to a horizontal rotary compressor, in particular to an internal gas guiding mechanism of the horizontal rotary compressor. Background technique [0002] US Patent No. 521191 proposes to use an internal gas guiding mechanism in a horizontal rotary compressor to guide the flow direction of gas inside the horizontal compressor. However, adding the internal gas guide mechanism during the manufacturing process of the compressor will increase the manufacturing cost and lead to a decrease in production efficiency. At the same time, due to the limitation of the installation space or the installation method, it may be necessary to cancel the interfering parts, such as the muffler, after adding the gas guiding mechanism, which will lead to deterioration in performance. [0003] figure 1 It is a specific structural diagram of the internal gas guiding mechanism used in the horizontal rotary compressor in the prior art. The shaft shaft of th...
