What do you know about the engine pump?

Working principle of engine pump

Engine pumps are simply pumping that cool the engine to prevent it from getting too hot and breaking down.

How the engine pump works:  Through the pulley drive of the pump bearing and impeller rotation, the cooling fluid in the pump is driven by the impeller to rotate together, under the action of centrifugal force is thrown to the edge of the pump shell, at the same time to produce a certain pressure, and then from the outlet or pipe flow. The center of the impeller is thrown out of the cooling fluid and the pressure decreases. Under the pressure difference between the inlet of the pump and the center of the impeller, the cooling fluid in the water tank is sucked into the impeller through the pipe, so as to realize the reciprocating cycle of the cooling fluid. When the impeller rotates, the water in the pump is driven by the impeller to rotate together. Under the action of centrifugal force, the water is thrown to the edge of the impeller, and then the outlet pipe is pressed into the engine water sleeve by the outlet pipe tangent to the impeller on the shell.

Care should be taken when installing the new pump

At the same time, the pressure at the center of the impeller decreases, and the water in the radiator is sucked into the central part of the impeller through the inlet pipe. With a continuous effect, the water pump keeps cooling water circulating in the waterway. After the cooling water absorbs heat in the jacket, it flows through the radiator, sends heat into the air, and then flows into the jacket to circulate to ensure that the engine works at the best temperature. If the water pump stops working for some reason, the cooling water can still flow between the impeller blades and carry out a heat flow cycle, which is not caused by overheating soon.  After a proper range of mileage, the water pump shall be replaced with a timely belt. It is sometimes seen that the pump is damaged in a short time after installing a new timing belt. This is usually due to increased belt tension. Therefore, when installing a new pump, do not lightly change a new belt. Landtopmall, are a professional engine parts supplier with many years of experience.

What do you know about the engine pump?

The function of the engine pump

The function of the engine pump is to drive the cooling fluid to dissipate the heat of the engine, ensure that it circulates in the cooling system, keep the water circulating in the radiator, take away the heat, and ensure that the engine is not too hot.  The cylinder of the automobile engine contains many waterways for cooling water circulation, which is connected by pipes to the radiator placed in the front of the car to form a large water circulation system. The water pump is installed at the upper outlet of the engine, driven by a fan belt, draws hot water from the engine cylinder channel, and pumps cold water into it. There is also a thermostat next to the pump. When the car first started, it did not open so that the cooling water would only circulate inside the engine and not pass through the tank. When the engine temperature reaches more than 95 degrees, it will open, and the hot water inside the engine will be pumped into the tank, and the cold air inside the car will blow through the tank to take away heat.  The working principle of the pump is that the engine drives the pump bearing and impeller rotating through the pulley, and the cooling fluid in the pump is driven by the impeller to rotate together. Under the action of centrifugal force, it is thrown to the edge of the pump shell, and at the same time it produces certain pressure, and then flows out of the outlet or pipe. As the cooling fluid is thrown out, the pressure of the impeller center decreases, and the cooling fluid in the water tank is sucked into the impeller through the pipe under the pressure difference between the inlet of the pump and the center of the impeller, so as to realize the reciprocating cycle of the cooling fluid.

Other Matters needing attention

It is worthy of note that the bearing supporting the pump shaft is smooth with smooth grease, so it is necessary to prevent the cooling fluid from leaking into the smooth fat and prevent the liquid from leaking. The sealing measures for the water pump to prevent leakage include a water seal and gasket. The water seal dynamic seal ring and shaft are installed between the impeller and the bearing through the interference, and the water seal static seal seat is firmly attached to the pump shell, so as to reach the purpose of the sealing cooling fluid.   The pump housing is connected to the engine through a gasket and supports the moving parts such as bearings. There is also a drain hole on the pump housing, which is located between the seal and the bearing. Once there is a cooling fluid leakage through the water seal, it can be discharged from the drain hole, which has been prevented from entering the bearing cavity, while the bearing is smooth and the parts are corroded.
