Abstract
The utility model discloses a screw compressor refrigerator oil injection device, which comprises a screw compressor body. A left oil injection hole and a right oil injection hole are respectively arranged on two sides of a female-male rotor cavity formed in the body; a left sprayer and a right sprayer are respectively arranged in the left oil injection hole and the right oil injection hole; the tail ends of the left sprayer and the right sprayer are respectively abutted to one end of a left supporting ring and one end of a right supporting ring; the other end of the left supporting ring and the other end of the right supporting ring are respectively abutted to a left sealing flange cover and a right sealing flange cover; and the left sealing flange cover and the right sealing flange cover are fixed onto the body. The screw compressor refrigerator oil injection device is capable of simultaneously injecting refrigerator oil into an element volume compression cavity formed by mutually meshing a female rotor and a male rotor from two sides of the body, and mixing the refrigerator oil with refrigerant gas more evenly. Besides, heat exchange is more sufficient, and the exhaust temperature of a compressor is reduced effectively.
Description
Technical field
The utility model relates to the accessory in the helical-lobe compressor, refers to a kind of helical-lobe compressor refrigerator oil injection apparatus particularly.
Background technique
In helical-lobe compressor, refrigeration working medium gas is inhaled in the formed element volume of a pair of intermeshing negative and positive rotor, carries out discharging after the closed compression, forms High Temperature High Pressure refrigeration working medium gas.According to the physical property of gas, compress that at the end the temperature of gas will be up to 150～200 ℃, if do not spray into cooling medium in compression chamber in gas compression processes, this high temperature all is unaffordable for component such as common compressor housing and bearings.Therefore, helical-lobe compressor must spray into an amount of refrigerator oil in compression chamber in compression process, to reduce the temperature of refrigerant vapour, compressor is normally moved.
In addition, the refrigerator oil that sprays into can form oil film on the tooth Surface of action of negative and positive rotor, the negative and positive rotor flank of tooth is spaced from each other, and the negative and positive rotor flank of tooth directly is not in contact with one another in engagement and transmission process, reduces the wearing and tearing of the flank of tooth.Simultaneously, the refrigerator oil that sprays into can also be filled the gap between rotor and the body hole, reduces gas leakage, absorbs the energy of gas random vibration, plays the effect that reduces pneumatic noise.
At present, existing helical-lobe compressor only has the refrigerator oil nozzle opening in the negative and positive rotor cavity one side design of body usually.In this case, the refrigerator oil that sprays in the compression chamber is too concentrated, can not evenly distribute in whole element volume, makes refrigerator oil fully not contact mixing with refrigeration working medium gas, thereby can not carry out heat exchange fully.Concerning large-scale compressor, the temperature of compressor air-discharging is still very high especially.
Summary of the invention
The purpose of this utility model will provide a kind of exactly can spray into refrigerator oil effectively in compressor, refrigerator oil and refrigeration working medium gas are evenly mixed and carry out the helical-lobe compressor refrigerator oil injection apparatus of sufficient heat exchange.
For achieving the above object, the helical-lobe compressor refrigerator oil injection apparatus that the utility model is designed, the body that comprises helical-lobe compressor, the negative and positive rotor cavity both sides that form in the described body offer left nozzle opening and right nozzle opening respectively, be respectively arranged with left shower nozzle and right shower nozzle in described left nozzle opening and the right nozzle opening, the tail end of described left shower nozzle and right shower nozzle respectively with an end butt of left supporting ring and right supporting ring, the other end of described left supporting ring and right supporting ring respectively with left sealing flange cover and right sealing flange cover butt, described left sealing flange cover and right sealing flange cover are fixed on the body.
As preferred version, described left nozzle opening and right nozzle opening are arranged symmetrically in the both sides of described negative and positive rotor cavity, so that the refrigerator oil equilibrium sprays into, guarantee that it evenly mixes with refrigeration working medium gas.
Further, described left nozzle opening and right nozzle opening are opened in the connection helical groove on the described negative and positive rotor cavity.Like this, refrigerator oil and refrigeration working medium gas mix and heat exchange more abundant, can effectively reduce the temperature of refrigerant vapour, guarantee that compressor normally moves.
Advantage of the present utility model is: designed helical-lobe compressor refrigerator oil injection apparatus can spray into refrigerator oil from the body both sides simultaneously in the negative and positive rotor is meshing with each other formed element volume compression chamber, refrigerator oil is more even with mixing of refrigeration working medium gas, heat exchange is more abundant thereby make, and then effectively reduces the delivery temperature of compressor.In addition, the equilibrium of refrigerator oil sprays into and can also play good lubrication to the negative and positive rotor, reduces the compressor internal leakage simultaneously, and reduces pneumatic noise.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Helical-lobe compressor refrigerator oil injection apparatus shown in the figure, the body 1 that comprises helical-lobe compressor, negative and positive rotor cavity 6 bilateral symmetry that form in the body 1 offer left nozzle opening a and right nozzle opening b, and left nozzle opening a and right nozzle opening b preferably are opened in the connection helical groove on the negative and positive rotor cavity 6.Be respectively arranged with left shower nozzle 2 and right shower nozzle 4 among left side nozzle opening a and the right nozzle opening b, the fine finishing spray-hole on left shower nozzle 2 and the right shower nozzle 4 can accurately be controlled the oil mass that sprays in the negative and positive rotor cavity 6.The tail end of a left side shower nozzle 2 and right shower nozzle 4 respectively with an end butt of left supporting ring 3 and right supporting ring 7, the other end of a left side supporting ring 3 and right supporting ring 7 respectively with left sealing flange cover 5 and right sealing flange cover 8 butts, left side sealing flange cover 5 and right sealing flange cover 8 are fixed on the body 1 by bolt assembly and gasket seal, can seal oil circuit effectively.During the utility model work, refrigerator oil enters left shower nozzle 2 and right shower nozzle 4 by oil circuit under the pressure of peripheral hardware injection system, and then evenly sprays into negative and positive rotor cavity 6 both sides, realizes the even distribution of refrigerator oil in whole element volume.
