Description
Technical field
The utility model relates to a kind of refrigeration plant, especially a kind of improved refrigeration compressor.
Background technique
Existing freezer refrigerating equipment all adopts refrigeration compressor.Existing refrigeration compressor exists energy consumption high, the shortcoming that refrigeration is not good.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of improved refrigeration compressor, can solve the deficiencies in the prior art, and compression efficiency is high, and good refrigeration effect is stable.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows: a kind of improved refrigeration compressor, comprise casing, in casing, be provided with one-level compression chamber and the two-stage compression chamber of series connection, in one-level compression chamber, be provided with piston, in two-stage compression chamber, be symmetrically arranged with two rotating eccentricity wheels, on one-level compression chamber, be provided with the first suction valve and first row air valve, on two-stage compression chamber, be provided with the second suction valve and second row air valve, between first row air valve and the second suction valve, by bellows, be connected; The bottom of one-level compression chamber is provided with fixing rod, and fixing rod is fixed on casing, between fixing rod and one-level compression chamber, is provided with elastic damping bar, and the width of elastic damping bar is less than the width of fixing rod; The two ends of the second compression chamber are provided with retaining ring, and retaining ring is fixed on casing by triangular supports.
As preferably, the side surface of described piston is tiltedly installed with several oil grooves.
As preferably, the side of described rotating eccentricity wheel is provided with balancing weight, and balancing weight is elliposoidal.
As preferably, the arranged outside of described bellows has thermal-protective coating.
The beneficial effect that adopts technique scheme to bring is: the utility model arranges two stage compression cavity by series connection, combines the advantage of reciprocating and rotary compression.To compress efficiency and improve 20%.Elastic damping bar can alleviate the resonance of one-level compression chamber, and fixing rod can be avoided rocking of one-level compression chamber.Two-stage compression chamber is owing to adopting the mode of rotary compression, and its scope of rocking is plane of rotation, by retaining ring, two-stage compression chamber can be connected in triangular supports securely, and triangular supports can be resisted the impact force of all directions, and intensity is high.The oil groove on piston side surface is for lube pistons, and balancing weight can reduce rotating eccentricity wheel bias when rotated and rock.Thermal-protective coating can avoid refrigerant to absorb heat in bellows, reduces energy consumption.
