A driving shaft of the electric motor is sequentially connected with the bearing, a low-pressure compression pump, an air exhaust hood, a middle-pressure compression pump, an air exhaust hood, a high-pressure compression pump and another air exhaust hood. The air exhaust pipe of the low-pressure compression pump is connected with the air suction pipe of the middle-pressure compression pump. The air exhaust pipe of the middle-pressure compression pump is connected with the air suction pipe of the high-pressure compression pump. Compared with the publicly known compressor, the utility model saves the energy of 50 %. One energy-saving refrigerating compressor of one match has same refrigerating amount with the publicly known refrigeration compressor of two matches in the same time. The utility model adopts the three-stage compression method, and the utility model is easily started.
Description
The utility model relates to a kind of refrigeration compressor.
Known refrigeration compressor as reciprocal compressor, is to be connected with the piston of cylinder interior by a motor drivening rod, has air-breathing door, exhaust valve to be connected with sucking pipe respectively on the cylinder; As rotary compressor, it is that a motor drives a compressed pneumatic pump.Though they can reach the purpose that the refrigerant vapor compression of low-temp low-pressure is become the refrigerant vapour of High Temperature High Pressure.But, make that the mechanical energy on the motor can not have been caused the energy loss of quite a few by good utilization because they all are disposable compressions.These compressors are the single stage compression mode that adopts all, make its refrigerating efficiency very low, have caused very big energy waste virtually.
The purpose of this utility model is the energy-conservation refrigeration compressor that will provide a kind of refrigerating efficiency high.
The purpose of this utility model is achieved in that and connects motor in casing, bearing, low pressure compressor pump, exhaust hood, middle pressure compressor pump, exhaust hood, high pressure compressed pump and exhaust hood are linked in sequence on the drive axle of motor, press the sucking pipe of compressor pump during the outlet pipe of low pressure compressor pump connects, the outlet pipe of middle pressure compressor pump connects the sucking pipe of high pressure compressed pump.
The utility model is compared the energy-conservation refrigeration compressor that can save energy 50%, with known compressor identical with known 2 refrigerating capacity of refrigeration compressor in the identical time.Owing to adopted low pressure, middle pressure and three grades of compress modes of high pressure, the period of exhaust of three cylinders to differ 120 degree angles again successively, so be easy to start than known compressor.

Low pressure compressor pump: low-pressure cylinder (9) internal diameter 45mm, low pressure rotary-piston (10) diameter 37.6mm, low pressure rotary-piston (10) thickness 58.24mm.
The middle compressor pump of pressing: middle air cylinder (12) internal diameter 45mm, middle pressure rotary-piston (13) diameter 37.6mm, middle pressure rotary-piston (13) thickness 17.76mm.
High pressure compressed pump: high pressure cylinder (15) internal diameter 30.6mm, high-pressure rotary piston (16) diameter 25.568mm, high-pressure rotary piston (16) thickness 17.76mm.
Differ 120 degree between low pressure rotary-piston (10), middle pressure rotary-piston (13) and the high-pressure rotary piston (16).
At first the stator of motor is fixed on the right-hand member of casing (2), install bearing (8) left, load onto rotor (6), install low-pressure cylinder (9) more left, low pressure rotary-piston (10) is fixed on above the transmission shaft (5), load onto slide plate (29), low pressure exhaust cover (11), again left and then low pressure exhaust cover (11) install middle air cylinder (12), middle pressure rotary-piston (13) also is fixed on the transmission shaft (5), load onto slide plate (29), middle pressure gas hood (14), install high pressure cylinder (15) more left, with high-pressure rotary piston (16) equally also is to be fixed on the transmission shaft (5), load onto high pressure gas cover (17), load onto fuel feeding spring (18) at the high order end of transmission shaft (5).Fix each component, errorlessly on inspection just can weld each outlet pipe, casing.Then low pressure buffer chamber (19) one ends are welded on the low pressure air suction pipe, end with middle pressure buffer cell (23) is welded on the low pressure exhaust pipe (21), press on the sucking pipe (22) during the other end is welded in, use high-pressure buffer chamber (25) to be welded between middle pressure tracheae (24) and the high pressure sucking pipe (26) again.On low pressure air suction pipe (20), on the low pressure exhaust pipe (21), on the middle pressure tracheae (24), a barometer is installed respectively on the high-pressure exhaust pipe (27) in addition, is convenient to detect, errorless on inspection after, the lubricant oil of just can annotating just can be installed in test-run a machine on the chiller plant.
The logical power supply of going up, this moment, the motor coil energising produced rotating magnetic field, made rotor (6) running, and transmission shaft (5) is the rotary-piston running of each air pump of interlock and then, and the refrigerant vapour of low-temp low-pressure is compressed.Refrigerant vapour is earlier by after the compression of low pressure compressor pump, press buffer cell (23) to send into the middle compressor pump of pressing in the warp, carry out second level compression, pass through high-pressure buffer chamber (25) again and send into the high pressure compressed pump, carry out third level compression, refrigerant vapour through after three grades of compressions has just become high temperature, the refrigerant vapour of high pressure.
At ambient temperature, after running after a while, be connected on the barometer on the sucking pipe of low pressure compressor pump, pressure is between 0.2～0.5 kilogram/cm2, the pressure of showing on the low pressure air pump discharge pipe is about 4.5 kilograms/cm2, in the gauge pressure of pressure tracheae end be about 12 kilograms/cm2, if the pressure of high-pressure exhaust pipe table be about 22 kilograms/cm2 the indicated pressure ramp of each barometer within the scope of above-mentioned air pressure, just working properly.
