An automobile water pump structure and its production process

Abstract

The invention discloses a vehicle water pump structure and a production process thereof. The vehicle water pump structure comprises a pump body outer shell; a motor chamber, a rotating shaft groove and an impeller chamber are arranged in the pump body outer shell in sequence from left to right; a water outlet pipe groove and a water inlet pipe groove are connected to the top end and the bottom endof the impeller chamber separately; a motor, a rotating shaft and an impeller disc are inserted in the motor chamber, the rotating shaft groove and the impeller chamber separately; a shaft sealing device is mounted at the right end of the rotating shaft groove through a shaft sealing groove; a temperature measuring water control valve is mounted on one side of the water inlet pipe groove througha mounting groove; the shaft sealing device improves the tight waterproof performance of the motor, and can prevent the waste of water resources; such electric devices as the motor are convenient to install, maintain or replace by means of a maintenance mounting door; the temperature measuring water control valve controls the water pumping flow of a vehicle water pump according to the temperatureof a vehicle driving device, so that the vehicle driving device is always maintained in a better working state, and the water resources and the energy are saved; and the pump body outer shell is manufactured by using a lost-wax process, so that the water pump production difficulty and cost are reduced.

Description

technical field [0001] The invention relates to the field of automobile water pumps, in particular to an automobile water pump structure and a production process thereof. Background technique [0002] The function of the automobile water pump is to pressurize the coolant to ensure its circulation in the cooling system. Generally speaking, it is to let the water continuously circulate through the radiator engine block. Take away the heat. . Make sure the engine is not overheating. [0003] The car water pump is in the cylinder block of the car engine. There are many water channels for cooling water circulation. It is connected with the radiator (commonly known as the water tank) placed in the front of the car through water pipes to form a large water circulation system. The water port is equipped with a water pump, which is driven by the fan belt to pump out the hot water in the water channel of the engine block and pump in the cold water. [0004] The composition of the ...

AI Technical Summary

Problems solved by technology

[0006] (1) The sealing of the water pump depends entirely on the sealing ring, and the sealing performance is not good. Water can easily enter the motor from the shaft hole and affect the life of the motor, and the motor is fixed in the water pump casing, which is extremely inconvenient for installation and maintenance;

[0007] (2) The speed of the cold water flowing out of the automobile water pump is the same at any time. When the heat of the automobile driving device is serious, the cold water supply is insufficient and the heat dissipation is insufficient, which reduces the life of the automobile driving device. When the heat of the automobile driving device is small, the cold water supply is too fast Can cause the waste of energy and cold water resource again;

[0008] (3) The traditional automobile water pump production process is to use the mold to directly cast the water pump casing, but the temperature of the metal solution is high, which requires high temperature resistance of the mold, and it is difficult to demould after the casting is formed, which increases the pressure of the automobile water pump. production difficulty
