Description
Technical field
The utility model relates to a kind of gear pump more particularly to a kind of gear pumps with collecting function Yu oil-control function；
Belong to gear mechanism field.
Background technique
Now, gear pump is that swept volume changes and movement is to convey liquid by being formed by between pumping cylinder and meshing gear
Or it is allowed to the drum pump being pressurized, and two enclosure spaces are formed by two gears, the pump housing and front and rear covers, it is interior by drawing liquid into
The volume in the space of portion's gear engagement side is squeezed into liquid in pipeline from becoming smaller greatly, and suction chamber and discharge chamber are by two
The path of contact of gear separates.The pressure of the outlet of gear pump depends entirely on the size of resistance at pump discharge, existing
Gear pump and causes it that cannot control oil liquid flow well, and will cause certain oil mass due to the sealing problem of gear
Waste.
Summary of the invention
(1) technical problems to be solved
A kind of in order to solve the above problems, the utility model proposes gear pump.
(2) technical solution
The gear pump of the utility model comprising: the pump housing, suction chamber, discharge room, mounting base；The mounting base passes through
It is welded and fixed and is arranged below the pump housing；The pump housing side is equipped with driving motor, and driving motor side is equipped with pump cover and tooth
Wheel shaft；The pump cover is equipped with screw；Master gear is equipped in the suction chamber, discharge room is equipped with power gear；Described
Master gear is connected with power gear with driving motor respectively by shaft；The suction chamber side is equipped with accumulator tank.
Further, the master gear is made of the gear that multiple groups are meshed, the gear that the multiple groups are meshed it
Between be equipped with partition, the outside of the partition is equipped with gasket.
Further, the gear shaft side is equipped with aseismatic mechanism, and the aseismatic mechanism is by placing groove and spring base
Composition, the spring base are embedded in placing groove, and its length is higher than placing groove, and the spring base is cylindrical structure,
It is internally provided with high-strength spring.
Further, the pump housing side is equipped with oil outlet and oil inlet, and its outside is equipped with metal layer, the gold
The inside for belonging to layer is equipped with buffer layer.
Further, the pump housing is coated with lubricant grease layer close to the side of pump cover.
(3) beneficial effect
Compared with the prior art, the utility model has the following beneficial effects: the gear pump of the utility model is equipped with
The gear that is meshed of multiple groups, worked by the meshing gear group for choosing different, thus to reach different rotating speeds, further
Achieve the purpose that the unequal oil liquid flow of control, it is more convenient to use, and the internal accumulator tank being equipped with, oil liquid is collected, is subtracted
Few loss.
Detailed description of the invention
