Abstract
The utility model discloses an unpowered oil-return device for a vapor compression cooling-water machine unit, which consists of two series pipelines connected in parallel; a first series pipeline consists of a solenoid valve and a restriction choke connected in series; a second series pipeline consists of a solenoid valve, an ejector and a hand valve connected in series; the solenoid valve inletsin the two series pipelines are communicated with an oil outlet of an oil separator formed at the outlet of a compressor in the vapor compression cooling-water machine unit through the pipelines; anoutlet of the restriction choke in the first series pipeline and an outlet of the hand valve in the first series pipeline are communicated with an inlet of the compressor and an outlet of a flooded evaporator through the pipelines; an ejecting port of the ejector in the second series pipeline is communicated with the flooded evaporator in the vapor compression cooling-water machine unit through aglobe valve. The utility model has a main advantage that the problem of insufficient oil supply of the compressor is effectively solved.
Description
Technical field
The utility model relates to the steam compression type handpiece Water Chilling Units, especially relates to the unpowered oil return apparatus that is used for the steam compression type handpiece Water Chilling Units.
Background technology
Existing steam compression type handpiece Water Chilling Units mainly is made up of compressor, condenser, expansion valve and evaporimeter.Because the chilled water of the evaporimeter of this unit is walked tube side, refrigerant is walked shell side, although the oil eliminator effect of system is fine, but still have the part compressor lubricant oil to escape and enter the refrigeration system from compressor with refrigerant, because it is lower to walk the refrigerant flow rate of shell side in the evaporimeter, compressor lubricant oil wherein can not be taken back compressor, cause compressor oil-supplying not enough and influence the normal operation of compressor.
The utility model content
The utility model purpose is to provide a kind of lubricating oil that compressor is discharged to send the unpowered oil return apparatus that is used for the steam compression type handpiece Water Chilling Units of compressor back to.
For achieving the above object, the utility model can be taked following technical proposals:
The unpowered oil return apparatus that is used for the steam compression type handpiece Water Chilling Units described in the utility model, it is made of two seriess pipe parallel with one another; Article one, series pipe is made of magnetic valve and flow controller series connection; The second series pipe is made of magnetic valve, injector and the series connection of hand valve; Magnetic valve import in two seriess pipe is connected by the oil eliminator oil-out that is positioned at the compressor outlet place in pipeline and the steam compression type handpiece Water Chilling Units; Article one, the hand valve outlet port in the flow controller in series pipe outlet, the second series pipe exports by pipeline and compressor inlet, flooded evaporator in the steam compression type handpiece Water Chilling Units and is connected; The ejecting port of injector is connected with flooded evaporator in the steam compression type handpiece Water Chilling Units by ball valve in the second series pipe.
Described injector is by the taper injection cavity that offers outlet and be arranged at its interior hollow cone tubular nozzle formation; The inlet seal of described nozzle extends outside the described taper injection cavity; Described ejecting port is opened in taper ejection cavity body sidewall.
The utility model advantage is by the flow controller in described article one series pipe the HTHP compressor lubricant oil of separating in the oil eliminator to be carried out sending suction side back to after the throttling step-down; Ejecting port by the injector in the described second series pipe is pumped to lubricating oil in the described flooded evaporator and low-temp low-pressure liquid refrigerants mixture in the injection cavity simultaneously, and the lubricating oil that enters with described jet hole, separates from oil eliminator evenly mixes the back and sends suction side back to from taper injection cavity outlet, thereby solved the problem of compressor oil-supplying deficiency effectively.
