Background

The compressor is a heart of a refrigeration system, sucks low-temperature and low-pressure refrigerant gas from a gas suction pipe, drives a piston to compress the refrigerant gas through the operation of a motor, and discharges the high-temperature and high-pressure refrigerant gas to an exhaust pipe to provide power for a refrigeration cycle, so that the refrigeration cycle of compression → condensation → expansion → evaporation (heat absorption) is realized. The compressor generally consists of a shell, a motor, a frame, a piston, control equipment (starter and thermal protector) and a cooling system. The frame is used for installing and fixing the motor, the crankshaft and the piston, and the structural characteristics of the frame directly influence the installation of other parts and the working performance of the whole compressor. The bearing capacity and stability of the compressor greatly influence the service life of the compressor, the stability and reliability of the compressor, and the performance indexes of the compressor, such as energy efficiency, noise, vibration and the like.

The high-pressure cavity (noise damping cavity) of the frame plays a good stress buffering role on the exhaust resistance of the compressor during exhaust, so that the stress of the piston during high-speed operation is reduced, high-temperature and high-pressure gas can be uniformly exhausted, the turbulent impact of the gas caused by the exhaust of the compressor complete machine and the noise and vibration generated are reduced, however, the original frame adopts a single-stage or two-stage noise damping cavity (such as the compressor frame shown in application numbers CN201320251642.X and CN 201420314159.6), the volume of the cavity is small, and the fluid resistance is further increased by the factors, and the operation performance of the compressor is influenced.

Set up the lubricating oil circulation mouth and can make in the bent axle through-hole unnecessary lubricating oil can follow the outflow in the lubricating oil circulation mouth on the holding ring to unnecessary lubricating oil can lubricate bent axle through-hole outside region, has reduced the gathering inside bent axle through-hole simultaneously.

Preferably, the frame body is provided with an annular stop block surrounding the positioning ring and positioned outside the positioning ring.

Set up annular dog and can effectively block lubricating oil and spill over to the outside, can also play sealed effect simultaneously, promote the sealing performance of crankshaft through-hole department.

Preferably, the annular stop block is provided with two circular oil drainage holes which are symmetrically arranged along the central line of the rack body.

Preferably, the valve plate mounting seat is provided with two symmetrically arranged mounting holes.

Therefore, the utility model discloses following beneficial effect has:

(1) through the design that adopts tertiary amortization chamber, under the unchangeable condition of single amortization chamber volume, can promote holistic volume to reduce the flow resistance of fluid in compression process, promoted the compression efficiency, makeed the operating performance of compressor promote by a wide margin.

(2) The redundant lubricating oil in the crankshaft through hole can be discharged, the redundant lubricating oil can lubricate the area outside the crankshaft through hole, and meanwhile, the accumulation of the redundant lubricating oil in the crankshaft through hole is reduced.

(3) Effectively improve the sealing performance of the through hole of the crankshaft.
