Abstract
The utility model belongs to a kind of helical-lobe compressor oil return apparatus of improvement.Problem to be solved is exactly that background technique exists: intermediate chamber pressure is lower, and before and after labyrinth seal, position pressure reduction is large, causes leakage rate larger; When working conditions of compressor changes, not in time, the oil level collected often can not have coupling in oil return, causes coupling to stir oil, causes vibration of compressor to strengthen and the problem of increasing power loss.Solving this technical problem adopted drip irrigation device is: the oil return after oil content filter core is again through the top inlet of throttle valve by pipeline UNICOM intermediate.Can be applicable to motor and have outside independent cooling, compressor inside has the semi-enclosed helical-lobe compressor of all kinds of labyrinth seal.
Description
Technical field: the utility model belongs to a kind of helical-lobe compressor oil return apparatus of improvement, be specially adapted to motor and have outside independent cooling, compressor inside has the semi-enclosed helical-lobe compressor of all kinds of labyrinth seal.
Background technique: the basic structure of existing helical-lobe compressor oil return apparatus of the same type is: flow through throttle valve from the gas mixture after oil content filter core and enter compressor air suction mouth by an independent pipeline, the intermediate inside connecting motor and compressor arranges the coupling connecting motor shaft and screw axis, between screw axis and body, labyrinth gland is set, screw axis screw connection rotor, body is arranged compressor air suction mouth, intermediate bottom outlet connects filter, pipeline visor and needle-valve and intakeport UNICOM by pipeline.The inner lubricant oil leaked by positions such as labyrinth seals of compressor, is collected in the bottom of intermediate, gets back to compressor air suction mouth through the pipeline be made up of filter, pipeline visor and needle-valve.Problem existing for this oil return apparatus is: intermediate chamber pressure is lower, and before and after labyrinth seal, position pressure reduction is large, causes leakage rate larger; When working conditions of compressor changes, not in time, the oil level collected often can not have coupling in oil return, causes coupling to stir oil, causes vibration of compressor to strengthen and increasing power loss.
Summary of the invention: the purpose of this utility model is exactly the helical-lobe compressor oil return apparatus proposing a kind of improvement, exists to solve background technique: intermediate chamber pressure is lower, and before and after labyrinth seal, position pressure reduction is large, causes leakage rate larger; When working conditions of compressor changes, not in time, the oil level collected often can not have coupling in oil return, causes coupling to stir oil, causes vibration of compressor to strengthen and the problem of increasing power loss.Solving this technical problem adopted technological scheme is: a kind of helical-lobe compressor oil return apparatus of improvement, the intermediate inside connecting motor and compressor arranges the coupling connecting motor shaft and screw axis, between screw axis and body, labyrinth gland is set, screw axis screw connection rotor, body is arranged compressor air suction mouth, intermediate bottom outlet connects filter, pipeline visor and needle-valve and intakeport UNICOM by pipeline, it is characterized in that the oil return after oil content filter core again through the top inlet of throttle valve by pipeline UNICOM intermediate.
The beneficial effect that the utility model is had compared with the prior art is: owing to adopting technique scheme, first the top inlet of intermediate is entered through the gas mixture of throttle valve, then flow out from the bottom outlet of intermediate, get back to compressor air suction mouth through the pipeline be made up of filter, pipeline visor and needle-valve etc.Like this, after entering intermediate from the gas mixture after oil content filter core, the internal pressure of intermediate can be increased, position, the front and back pressure reduction of labyrinth seal significantly be reduced, thus significantly can reduce the leakage rate of labyrinth seal; In addition because the gas mixture oil content after oil content filter core is little, after entering intermediate according to above-mentioned pipeline, effect because of gas pressure can control oil level bottom it and remain at bottom line, effectively avoid oil level to rise the hidden danger brought compressor operating, compressor operating is not existed to other adverse effect simultaneously.
Accompanying drawing illustrates: Fig. 1 is the utility model overall structure schematic diagram.
