Description
Technical field
The utility model relates to a kind of cold water or source pump centrifugal compressor gs-oil separator.
Background technology
Existing refrigeration air-conditioner, chemical industry, centrifugal cold water or source pump that industries such as medicine are generally used, be to make purer relatively refrigerant be used for the normal lubricated of kind of refrigeration cycle and guarantee bearing of compressor during its operation, the mixture of refrigerant and lubricating oil fully must be separated, the screen separator of installing on the centrifugal compressor for separating of the mixture of refrigerant and lubricating oil, usually cause a part of lubricating oil drop to enter the unit kind of refrigeration cycle with the refrigerant gas of discharging because separating effect is bad, after the lubricating oil drop of being walked by the refrigerant band of gas participates in kind of refrigeration cycle with refrigerant, seriously reduce compression and the heat exchange efficiency of unit, caused the operational efficiency of whole unit to reduce greatly.For obtaining better separating effect, conventional solution is thickness and the size that improves the precision of steel wire and strengthen steel wire, thereby the order number of steel wire is more and more, under the condition that guarantees the certain pressure loss, the size of steel wire is increasing, cause corresponding cost up, and be unfavorable for the integral arrangement of compressor.
The utility model content
The utility model purpose provides the gs-oil separator of a kind of fully separate compressors refrigerant and lubricating oil mixture.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cold water or source pump centrifugal compressor gs-oil separator, comprise airtight cylindrical shell, be arranged on the gas mixture import on the airtight cylindrical shell, the outlet of refrigerant gas, liquid lubricating oil outlet, described cylinder inboard wall is connected with deflection plate both sides, this deflection plate end face is connected with the cylindrical shell end face, between deflection plate bottom and the cylindrical shell bottom space that can make air-flow pass through and change direction is set, described gas mixture import and the outlet of refrigerant gas are installed in the top of cylindrical shell, and place the both sides of deflection plate respectively, described liquid lubricating oil outlet is positioned at the cylindrical shell foot.
Useful technique effect of the present utility model is: in the utility model, because in cylindrical shell, be provided with deflection plate, the deflection plate of flowing through after gas mixture enters cylindrical shell changes the flow direction, in cylindrical shell, form cyclone, wherein liquid lubricated oil droplet is then because gravity and action of centrifugal force are unrestrained behind cylinder inboard wall and bottom, discharged by liquid lubricating oil outlet, thereby realize separating of lubricating oil and refrigerant gas.This separator good separating effect has been given up parts such as screen pack, and is simple in structure, and easy accessibility is convenient to safeguard.

The specific embodiment
Arrive a kind of cold water shown in Figure 3 or source pump centrifugal compressor gs-oil separator as Fig. 1, comprise airtight cylindrical shell, be arranged on the gas mixture import 7 on the airtight cylindrical shell, refrigerant gas outlet 6, liquid lubricating oil outlet 5, described cylinder inboard wall is connected with a deflection plate 3 both sides, these deflection plate 3 end faces are connected with the cylindrical shell end face, between deflection plate 3 bottoms and the cylindrical shell bottom space that can make air-flow pass through and change direction is set, described gas mixture import 7 and refrigerant gas outlet 6 are installed in the top of cylindrical shell, and place the both sides of deflection plate 3 respectively, described liquid lubricating fluid outlet 5 is positioned at the cylindrical shell foot.Because in cylindrical shell, be provided with deflection plate 3, the deflection plate 3 of flowing through after gas mixture enters cylindrical shell changes the flow direction, in cylindrical shell, form cyclone, wherein liquid lubricated oil droplet is then because gravity and action of centrifugal force are unrestrained behind cylinder inboard wall and bottom, discharged by lubricating oil outlet, thereby realize separating of lubricating oil and refrigerant gas.This separator good separating effect has been given up parts such as screen pack, and is simple in structure, and easy accessibility is convenient to safeguard.
Described cylindrical shell is made up of upper cover plate 1, lower cover 4 and cylindrical shell body 2, described deflection plate 3 both sides and cylindrical shell body 2 sidewall seamless connectivities, deflection plate 3 end faces and upper cover plate 1 seamless connectivity, described liquid lubricating fluid outlet 5 is positioned on the lower cover 4, and described deflection plate 3 is at least one.In order to make separating effect better, gas mixture import 7 centers and deflection plate 3 are selected 30 degree for use overlooking the angular separation, and the outlet 6 of refrigerant gas and gas mixture import 7 are selected 90 degree for use at the angle of overlooking direction.Described deflection plate 3 arranges for the length limit, and the bottom is an inclined-plane, and minor face is near gas mixture import 7, and inclined-plane centre distance lower cover 4 highly is 0.8-1.2 times of cylindrical shell body 2 diameters.Deflection plate 3 length limits the pressure loss that can reduce gas is set, and this design better effects if that gas mixture is separated.
Arrive shown in Figure 3 as Fig. 1, be provided with a deflection plate 3 in the airtight cylindrical shell of being formed by upper cover plate 1, lower cover 4 and cylindrical shell body 2, in order to reduce the pressure loss of gas, deflection plate 3 arranges for the length limit, gas mixture import 7 and refrigerant gas outlet 6 all are located at cylindrical shell top, while gas mixture import 7 is overlooked the position that direction becomes 30 degree angles installations and is in close minor face with deflection plate 3, and refrigerant gas outlet 6 is installed in deflection plate 3 opposite sides also and gas mixture import 7 is 90 degree settings.Inclined-plane centre distance lower cover 4 is set simultaneously highly is 1 times of cylindrical shell body 2 diameters, when striking deflection plate, gas mixture forms cyclone, because deflection plate 3 both sides end faces and upper surface are tightly connected with cylindrical shell body 2 and upper cover plate 1 respectively, can make gas mixture gas can both pass through deflection plate 3 bottoms like this, guarantee separating effect.After gas enters cylindrical shell formation cyclone, liquid lubricating oil in the gas mixture is because gravity and action of centrifugal force are thrown to cylinder lateral wall and bottom, and via liquid lubricating oil outlet 5 discharges that are arranged on the lower cover 4, the refrigerant gas after the separation is then discharged by refrigerant gas outlet 6.
