Description
Technical field
The utility model relates to a kind of oil-immersed pump, refers in particular to the coaxial oil-immersed pump of a kind of oil hydraulic-pump rotor and rotor, belongs to the oil-immersed pump technical field.
Background technique
Existing oil-immersed pump motor connects malalignment with oil pump, and mechanical power loss is big, produces a large amount of heats during work, and the oil pump noise is also big.
Summary of the invention
The purpose of this utility model provide a kind of have energy-conservation, noise is low, long service life, oil-immersed pump that mechanical loss is little.
The utility model provides a kind of oil-immersed pump, comprises the big lid of oil pump, the pump housing, sliding bearing, metallurgical powder rotor (inner and outer rotors), oil pump tegillum, motor stator, rotor, rotor axis of electric, socket head screw.The pump housing is provided with two chambeies, with the big chamber of oil pump Da Gai joint be the oil loading pump motor, be provided with oily passage in the big chamber; With the chamber of oil pump tegillum joint be the chamber of dress metallurgical powder rotor; Be provided with plain bearing bore and oil-through hole between big chamber and the loculus on the pump housing.Oil pump covers greatly and is provided with pressure regulator valve, is provided with the connector assembly joint, and oil pump covers in addition oil outlet interface greatly, the screw hole that is connected with the pump housing in addition, and oil pump covers the via hole that is connected with main frame in addition greatly.Pressure regulator valve is provided with pressure regulator valve filler opening and pressure regulator valve oil outlet.The oil pump tegillum is provided with inlet port.
This oil hydraulic-pump rotor of the technical program and rotor are coaxial, have therefore reduced the mechanical power loss of motor with oil pump connection malalignment; Also reduced the noise of oil pump; Therefore oil pump is energy-conservation.Simultaneously the oil of oil pump hyperbaric chamber flows directly in the chamber of pump housing dress motor, the heat that produces in the time of can taking away machine operation like this, two sliding bearings that also can lubrication motor; Therefore the electric current of motor can surpass 10% and uses, be equivalent to oil pump the long-term cooling motor of oil of confession; Sliding bearing is subjected to the oily pressure lubrication of oil pump hyperbaric chamber; So long service life.To sum up, this oil pump has energy-conservation, advantage such as noise is low, long service life, mechanical loss are little.
