The utility model is described in detail below with reference to the accompanying drawings, and the wading Tian Shuibeng disclosed in the embodiment, as shown in fig. 2, includes a belt pulley 1, a water pump housing 2, a water pump bearing 3, and a water pump seal 4; one end of the water pump bearing 3 is provided with the belt pulley 1, the other end of the water pump bearing 3 is provided with the water pump housing 2, the front part of the water pump housing 2 is arranged in the belt pulley 1, the rear part in the water pump housing 2 is provided with the water pump seal 4, the water pump seal 4 is arranged in the water pump housing 2, one end of the water pump seal 4 is provided with the runner 5, the runner 5 is communicated with the water storage tank 6, and the side part of the water storage tank 6 is provided with the water drain hole 7.

The water pump casing 2 is internally provided with the water storage tank 6 and the water discharge hole 7, water is guided into the water storage tank 6 through the flow channel 5, and when the water in the water storage tank 6 reaches a certain amount, the water is discharged through the water discharge hole 7, so that the stability of the pressure in the water pump is ensured, and the water seal is prevented from being damaged.

The principle of pumping water by a water pump is that an impeller arranged on a pump shaft rotates at a high speed, and the interaction of the impeller and the force generated by the liquid to be conveyed enables the liquid to obtain energy so as to achieve the purpose of conveying the liquid.

The vane pump is divided into according to the working principle of the impeller: centrifugal pumps, axial flow pumps and mixed flow pumps. Centrifugal pumps are commonly used for horizontal pumps, axial pumps and mixed pumps are commonly used for vertical pumps. The centrifugal pump is characterized in that the impeller rotates continuously in the pump shell filled with water, water between blades on the impeller is centrifugally moved under the action of centrifugal force, and the water is flushed to the shell at a certain speed and under a certain pressure, and flows into the water outlet pipeline of the water pump through the flow channel 5 in the shell.

Meanwhile, the central part of the impeller forms vacuum, and water in the water suction pipeline flows into the central part of the impeller under the action of atmospheric pressure to fill the vacuum area; the water flowing into the central part of the impeller is acted by centrifugal force and then flows into the water outlet pipeline of the water pump through the shell. Thus, the continuous water conveying process of the water pump is completed as long as the water suction pipeline can keep water supplement and the impeller continuously rotates.

The effect of the water drain hole 7 of the water pump is that when the water pump pressure is too high, the water pump seal 4 is protected from being damaged through pressure relief of the water drain hole 7, when the water pump is used, the situation that the water pump pressure is too large can occur, at the moment, timely pressure relief is needed, water in the water pump is timely discharged, the water drain hole 7 is arranged for pressure relief, if the water drain hole 7 is blocked, the pressure in the water pump is extremely easy to cause too large, water cannot be timely discharged, the pressure can act on the water pump seal 4, the water pump seal 4 can be jacked up, gaps exist between the water pump seal 4 and the water pump shell 2, and the operation of the water pump is affected.

A drain hole 7 is provided to release pressure, and the drain hole 7 is provided in the front portion of the water pump housing 2. And the front portion of the water pump housing 2 is provided in the pulley 1. When the tractor runs, the tire can splash up sediment and other impurities, the water discharge hole 7 is opened outwards, the sediment or other impurities are extremely easy to splash into the water discharge hole 7, and if excessive sediment is accumulated, the water discharge hole 7 can be blocked.

Therefore, the water discharge hole 7 is arranged at the front part in the water pump shell 2, and the sputtered sediment can be blocked by the outer surface of the belt pulley 1, so that the water discharge hole 7 is protected, the belt pulley 1 can still rotate normally, and the normal use of the water pump is not influenced.

The runner 5 is obliquely arranged, and the runner 5 communicates the water seal 4 of the water pump with the water storage tank 6. One end of the water storage tank 6 is communicated with the flow channel 5, the other end of the water storage tank 6 extends to the front part in the water pump housing 2, a water discharge hole 7 is formed in the side part of the water storage tank 6, and the other end of the water storage tank 6 and the water discharge hole 7 are located at the front part of the water pump housing 2.

The splashing mud can be shielded by the pulley 1 to prevent the drain hole 7 from being blocked. The flow channel 5 is obliquely arranged, so that water flow can be rapidly guided into the water storage tank when the pressure is high, and then pressure is relieved in time. So that the water pump can discharge water rapidly when the pressure is high.

The water storage tank 6 is a circular groove. The water storage tank 6 is communicated with the water discharge hole 7. The water storage tank 6 is used for storing water flow flowing through the flow channel 5, the length of the water storage tank 6 is extended to the front part in the water pump shell 2, so that the water storage capacity of the water storage tank 6 is obviously enhanced, buffering can be provided for the discharge of the water discharge hole 7, the water with high pressure at the water seal 4 of the water pump is stored in time, namely, the pressure is discharged in time, the water seal 4 of the water pump is prevented from being extruded, and the water is guided away through the water discharge hole 7, so that the pressure release efficiency is improved.

The impeller of the water pump is made of cast iron. The blades on the water pump impeller play a main role, and the shape and the size of the water pump impeller are closely related to the performance of the water pump. The impeller of the water pump can be generally divided into a single-suction type and a double-suction type. The single suction impeller is a single-side water suction impeller, and the small flow water pump impeller is of a plurality of types. The double suction type impeller is characterized in that the double suction type impeller is used for absorbing water at two sides, and the large-flow water pump impeller is all the double suction type impeller. The rear part of the water pump housing 2 is provided with a water pump impeller which is arranged on a water pump bearing 3.

The belt pulley 1 belongs to a hub part, has relatively large relative size, and is mainly cast and forged in the manufacturing process. The outer surface of the pulley 1 of the water pump is provided with a plurality of annular grooves. The belt pulley 1 can be driven to alleviate load impact, and the belt pulley 1 is driven to operate stably with low noise and low vibration; and the structure is simple, and the adjustment is convenient.
