Abstract

The invention discloses an automobile engine cooling water pump. The automobile engine cooling water pump comprises a pump case. The pump case is composed of a main cavity in the middle, a gear cavityand an impeller cavity, and the gear cavity and the impeller cavity are located on the two sides of the main cavity. A gear is arranged in the gear cavity. An impeller is mounted in the impeller cavity. A rotary shaft is horizontally connected from the gear cavity to the impeller cavity. The rotary shaft penetrates through the whole pump case. An oil seal is arranged on the shaft wall of the rotary shaft in the main cavity. A water seal is arranged on the side, close to the impeller cavity, of the oil seal and is arranged around the shaft wall of the rotary shaft. The side, far away from theoil seal, of the water seal is closely attached to the inner wall of the main cavity. A ball groove is horizontally formed below the rotary shaft, and a steel ball is arranged in the ball groove. Oneend of the ball groove is arranged in the position, close to the gear cavity, of a main cavity inner wall. A cooling liquid channel is arranged below the ball groove. The cooling liquid channel is connected between the main cavity inner wall and the impeller below the ball groove. The cooling liquid channel and the inner wall of the lower end of the main cavity are fixed through a supporting piece. The automobile engine cooling water pump improves the working efficiency, reduces manpower and material resources, achieves the better lubricating effect, reduces noise and is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to an automobile engine cooling water pump. Background technique [0002] In the cylinder block of the car engine, there are many water channels for cooling water circulation, which are connected with the water tank placed at the front of the car through water pipes to form a large water circulation system. The cooling water pump is located at the upper water outlet of the engine, and the engine passes through the pulley Drive, pump out the hot water in the water channel of the engine block, and pump the cold water in. There is a thermostat next to the water pump. When the car is just started (cold car), it is not turned on, so that the cooling water does not pass through the water tank, but only circulates in the engine. When the temperature of the engine reaches above 95 degrees, it is turned on, and the engine The hot water in the car is pumped into the water tank, and the c...
