Abstract
The utility model belongs to the technical field of an oil pump and particularly relates to a corrosion-resisting gear oil pump. The corrosion-resisting gear oil pump comprises a pump shell; an oil liquid inlet end is arranged on one side of the pump shell and an oil liquid outlet end is arranged on the other side of the pump shell; a driving gear and a driven gear engaged with the driving gear are arranged inside a cavity of the pump shell; and a corrosion-resisting layer is arranged on the inner wall of the cavity of the pump shell, and the thickness of the corrosion-resisting layer is in a range of 2mm to 8mm. According to the corrosion-resisting gear oil pump, the corrosion-resisting layer is arranged inside the pump shell, so that the inner wall of the pump shell can be effectively prevented from being corroded and the service life of the pump shell is prolonged.
Description
Technical field
The utility model belongs to oil pump technology field, is specifically related to a kind of corrosion resistant gear oil pump.
Background technique
The working principle of gear oil pump is, the flank of tooth of pump case, end cap and driving gear, driven gear forms the active chamber of sealing, and driving gear and driven gear constantly rotate, and the gear teeth are a pair of follows a pair of intermeshing, fluid just constantly sucks from entrance point, extrudes from outlet end.The medium that oil pump sucks is diesel oil or gasoline, because diesel oil and gasoline all have corrosivity, it is inhaled in the pump housing, can form certain corrosion to the inwall of the pump housing, through corrosion can be at the corrosion piece of pump housing inwall generation stammerer shape for a long time, affect the working life of the pump housing, corroding simultaneously piece can flow in the working equipment together along with fluid, reduces the using character of fluid.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of corrosion resistant gear oil pump, is provided with one deck anti-corrosion layer in its pump case, and it can effectively prevent the corrosion of pump case inwall, prolongs the working life of pump case.
The realization the technical solution of the utility model is as follows:
A kind of corrosion resistant gear oil pump, comprise pump case, one side of pump case is that fluid entrance point, opposite side are the fluid outlet end, in the cavity of pump case, be provided with driving gear, reach the driven gear with the driving gear engagement, the cavity inner wall of described pump case is provided with one deck anti-corrosion layer, and the thickness of described anti-corrosion layer is between 2mm-8mm.
The thickness of described anti-corrosion layer is 3mm.
The thickness of described anti-corrosion layer is 5mm.
The thickness of described anti-corrosion layer is 7mm.
Adopted such scheme, under the engagement driving of driving gear and driven gear, to the gesture of fluid formation suction, fluid enters in the pump case from the fluid entrance point, discharge from the fluid outlet end again, thus the conveying function of realization pump; And owing in pump case, be provided with one deck anti-corrosion layer, the fluid that enters in the pump case is difficult to the pump case inwall is caused corrosion, thereby prolong the working life of pump case, while pump case inwall can not occur following fluid because of the impurity that stammerer forms yet and enter in the working equipment, has promoted the using character of fluid.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1 is pump case, and 2 is the fluid entrance point, and 3 is the fluid outlet end, and 4 is driving gear, and 5 is driven gear, and 6 is axle, and 7 is axle, and 8 is anti-corrosion layer.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Referring to Fig. 1, a kind of corrosion resistant gear oil pump, comprise pump case 1, one side of pump case is that fluid entrance point 2, opposite side are fluid outlet end 3, is provided with driving gear 4 in the cavity of pump case, reaches the driven gear 5 with the driving gear engagement, driving gear is arranged in the pump case by axle 6, one end of axle reaches the pump case outside and is used for being connected with drive motor, and driven gear is arranged in the pump case by axle 7, rotates thereby driving gear can drive driven gear; The cavity inner wall of pump case is provided with one deck anti-corrosion layer 8, and the thickness of anti-corrosion layer is between 2mm-8mm.In the implementation, the thickness of anti-corrosion layer can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm.
