Described lubricating point filler opening is communicated with the lubricating point of bearing and compression chamber by passage.
Oil pump is delivered to lubricating point filler opening by oil pump outlet line the oil in oil storage tank, lubricating point filler opening is delivered to bearing and compression chamber by passage lubricant oil again, bearing and compression chamber to refrigeration helical-lobe compressor is lubricated, sealing and cooling, the lubricant oil that enters bearing and compression chamber is finally discharged from outlet pipe, after separation, lubricant oil falls in oil storage tank, lubricant oil in oil storage tank is taken away by oil pump again, forms thus a circulation.
The utility model adopts oil pump to be coaxially connected with male rotor, and the motor by refrigeration helical-lobe compressor drives simultaneously, has saved a motor configuring with oil pump.And oil pump is arranged in electric machine casing, even if exist, leak, the lubricant oil leaking out and refrigerant gas are sucked into the compression chamber of refrigeration helical-lobe compressor, and lubricant oil and refrigerant gas circulate all the time in system.The utility model has the advantages that and saved the operating cost of refrigeration helical-lobe compressor and improved system operation reliability and Security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Fig. 1 illustrates a mode of execution of the present utility model, comprises housing 3, oil pump 11 and is arranged on the interior intermeshing female rotor 4 of housing 3 and with the male rotor 5 of main shaft.One end of the main shaft of this male rotor 5 connects motor 7 and an extension 18 is set.The main shaft of described male rotor 5 is again as electric machine main shaft.Motor drives male rotor to rotate together with female rotor.
Described housing 3 one end arrange air-breathing lid foundry goods 8, and the other end arranges oil content barrel 1.The bottom of described air-breathing lid foundry goods 8 is provided with refrigerant gas import 11.Refrigerant gas enters through motor 7 from refrigerant gas import 11, motor 7 is carried out cooling, then enters the compression chamber that male rotor 5 and female rotor 4 form and compresses, and in compression process, from passage 17, sprays into lubricant oil.Refrigerant gas after overcompression and lubricant oil enter oil content barrel 1 by outlet pipe 14.One end of this outlet pipe 14 is connected with the exhaust end of compression chamber, and the other end is through oil content filter screen 2, and the outlet of described outlet pipe 14 is over against the sidewall of oil content barrel 1.The top of described oil content barrel 1 is provided with relief opening 15, and bottom is provided with oil storage tank 13.Described oil content filter screen 2 is radially arranged between the outlet and refrigerant gas relief opening 15 of outlet pipe 14.
Refrigerant gas after compressed and lubricant oil are discharged from outlet pipe 14, collide with the sidewall of oil content barrel 1, and gravitate parts of lubricating oil falls to the oil storage tank 13 of oil content barrel 1 bottom.Lubricant oil after first separation and mixture of refrigerant gases, through oil content filter screen 2, carry out separation for the second time, and the lubricant oil after separation falls to oil storage tank 13, and a small amount of lubricant oil of refrigerant gas band is discharged from relief opening 15.
