Description
Technical field
The utility model belongs to compressor accessory technical field, particularly relates to improved type compressor cylinder base.
Background technique
Compressor, being a kind of driven fluid machinery low-pressure gas being promoted to pressurized gas, is the heart of refrigeration system.It sucks the refrigerant gas of low-temp low-pressure from sucking pipe, after driving piston to compress it by motor rotation, the refrigerant gas of High Temperature High Pressure is discharged to outlet pipe, for refrigeration cycle provides power, thus realize the refrigeration cycle of compression → condensation (heat release) → expand → evaporate (heat absorption).Cylinder seat is a conventional accessory in compressor, and high-pressure refrigerant can through cylinder seat.At present, its passage for high-pressure refrigerant process of existing cylinder seat has the passage of multi-segment structure, then carry out noise reduction process, but existing noise-reducing structure majority is single noise reduction chamber, and secondly, gas is comparatively large, and erasure effect is poor and impracticable.
Such as, Chinese patent discloses hermetically sealed compressor, application number [200820067102.5], it has housing, is provided with spindle nose in the center of housing, spindle nose opens axis hole, be provided with cylinder head in the front side of housing, the both sides of cylinder head are furnished with air-breathing silencing cavity and exhaust noise silencing chamber, cylinder head have cylinder holes and suction port and exhaust port, it is characterized in that: housing and spindle nose adopt solid slab face to be integrally connected, and respectively have an oil leaking hole in both sides, solid slab face; The program can increase the intensity of cylinder block, can prevent refrigerator oil from entering motor gas-gap simultaneously, reduces power loss, and volume is little, reasonable in design, be convenient to processing and assembling, be conducive to reducing noise and vibration, be particularly suitable for improving stage clip structural formula cylinder block.
Although above-mentioned scheme has above plurality of advantages, above-mentioned scheme unresolved above-mentioned technical problem.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, good muffling effect and can reduce the improved type compressor cylinder base of gas.
For achieving the above object, the utility model have employed following technical proposal: this improved type compressor cylinder base comprises pedestal, pedestal is provided with refrigerant gas passage and the noise-reducing structure with refrigerant gas channel connection, this noise-reducing structure comprises at least one the outer ring hush pipe being arranged on pedestal one side, be provided with in outer ring hush pipe and there is circular hush pipe in the first noise reduction chamber, the second noise reduction chamber is formed between described outer ring hush pipe and interior circular hush pipe, described refrigerant gas passage outer end is in communication with the outside, the inner successively with the second noise reduction chamber and the first noise reduction chamber.
In above-mentioned improved type compressor cylinder base, the shaft axis of described outer ring hush pipe overlaps with the shaft axis of interior circular hush pipe and arranges.
In above-mentioned improved type compressor cylinder base, described outer ring hush pipe and pedestal are connected as a single entity structure; Described interior circular hush pipe and pedestal are connected as a single entity structure.
In above-mentioned improved type compressor cylinder base, described refrigerant gas passage comprise be arranged on pedestal and with the first through hole of the second noise reduction chamber, interior circular hush pipe is provided with can by the second through hole of the second noise reduction chamber and the first noise reduction chamber.
In above-mentioned improved type compressor cylinder base, the shaft axis of the first described through hole overlaps with the shaft axis of the second through hole.
Alternatively scheme, in above-mentioned improved type compressor cylinder base, the shaft axis of the first described through hole does not overlap with the shaft axis of the second through hole.
In above-mentioned improved type compressor cylinder base, the aperture of the first described through hole is greater than the aperture of the second through hole.
Compared with prior art, the advantage of this improved type compressor cylinder base is: 1, design is more reasonable, and being provided with two noise reduction chambers can improve erasure effect, that is, greatly reduce noise, secondly, also reduces the pulsation of air-flow, practical.2, structure is simple and be easy to manufacture.
