Reciprocating compressor

Abstract

The present invention relates to reciprocating compressor. In the reciprocating compressor, in which the piston combined with rotor reciprocates linearly inside cylinder, the spring support stage has radial spring supporting parts for the front and back resonant springs and is easy to manufacture. The spring support stage has extending side spring installing part and the back frame has partially split part, so that the present invention has reduced back frame size, casing size and compressor size, decreased material cost, easy motor and compressor heat dissipation and raised compressor efficiency.

Description

technical field [0001] The invention relates to a compressor, in particular to a reciprocating compressor which is installed with double resonance springs and simplifies the structure of the spring support platform. Background technique [0002] Generally, a reciprocating compressor makes the piston reciprocate inside the cylinder to suck in, compress and discharge the gas. [0003] Such as figure 1 As shown, the prior art reciprocating compressor includes a frame assembly 20 that is elastically supported inside the casing 10; a reciprocating motor 30 that is fixed on the frame assembly 20 and generates a linear driving force; A compression assembly 40 that sucks and compresses fluid on the frame assembly 20; a resonant spring assembly that is combined between the frame assembly 20 and the rotor 33 of the reciprocating motor 30, and makes the rotor 33 and the piston 42 of the compression assembly 40 perform resonant motion 50. [0004] The frame assembly 20 is by one side...

Problems solved by technology

[0012] However, in the conventional reciprocating compressor as described above, the spring mounting portions 51A, 51B of the spring support base 51 are radially formed, and the front resonant spring 52 and the rear resonant spring 52 are arranged around the front and rear sides of each spring mounting portion 51A, 51B. Part resonance spring 53 is installed around the circumferential direction, which makes the structure of spring supporting platform 51 complicated and difficult to manufacture.

And, when assembling the rear frame 23, because the rear resonance springs 53 arranged at equal intervals around the circumferential direction of the rear frame are all supported, the volume of the rear frame 23 becomes larger, and the material cost increases. Also becomes larger, so that the volume of the compressor increases

Since the recessed part 23a of the rear frame 23 forms an integral structure, the heat generated by the motor mechanism part cannot be discharged, causing the motor to overheat or the suction gas to be heated, causing the problem of suction loss
