Motorcycle water pump cover with possible function

Abstract

The invention relates to a motorcycle water pump cover with a possible function, which comprises a cover body, wherein a water cavity is arranged on the inner wall of the cover body; the water cavity becomes larger and larger and is shaped like an involute; a water inlet tap and a water outlet tap are arranged on the cover body; an impeller matched with a water pump shaft is arranged at the outer top of the water cavity; a plurality of back blades are arranged on the impeller to form an involute helicoids; the center of the impeller corresponds the inner hole of the water inlet tap; a mounting hole is formed in the top of the cover body; an observation window is mounted in the mounting hole; the observation window comprises a ring-shaped frame and a transparent baffle plate; a mounting groove is formed in the inner side wall of the ring-shaped frame in the circumferential direction; the transparent baffle plate is clamped in the mounting groove; a rubber layer is stuck to the outer side wall of the ring-shaped frame; the outer diameter of the rubber layer is greater than the diameter of the mounting hole; and the outer wall of the rubber layer is stuck to the inner wall of the mounting hole and is in sealing fit with the inner wall of the mounting hole. The water pump cover adopting the structure can avoid water leakage of the water taps, improves the water pumping capacity, and ensures the water cooling effect of an engine. Besides, the condition in the water cavity can be observed via the visual window, and the water pump cover has the characteristics of simple structure, convenience in assembly and low cost.

Description

technical field [0001] The invention relates to a liquid pump part used on a motorcycle, in particular to a motorcycle water pump cover with possible functions. Background technique [0002] The water pump is an important part of the water circulation cooling system of the water-cooled motorcycle. The water-cooled motorcycle is provided with a cooling water tank, and the water in the cooling water tank is pumped into the engine cylinder through a water pump for cooling cycle, and then returns to the cooling water tank to complete a water circulation cooling process. The existing water pump cover is generally made of metal as a whole, and the water pump cover is installed on the right crankcase of the water-cooled engine of the motorcycle. When the water-cooled engine of the car is still and not working, check the water cooling system of the engine, for example: whether the water tank is short of water, whether the water pipe is blocked, whether the water pipe is broken and ...

AI Technical Summary

Problems solved by technology

The existing water pump cover is generally made of metal as a whole, and the water pump cover is installed on the right crankcase of the water-cooled engine of the motorcycle. When the water-cooled engine of the car is still and not working, check the water cooling system of the engine, for example: whether the water tank is short of water, whether the water pipe is blocked, whether the water pipe is broken and leaking, etc.; The gap between them is not easy to control, and due to processing and mold wear, it is easy to cause interference between the water pump cover and the right crankcase cover

3. The water nozzle of the water pump is a separate component, and it is press-fitted with the right crankcase cover. On the one hand, it needs to be processed and installed separately, and the cost is high; on the other hand, the quality of the press-fit directly affects its sealing performance. Strict requirements on the assembly process, prone to water leakage
