How the product works
In the upper water outlet of the engine, there is a water pump,
which passes through the belt
to drive, pump out the hot water in the water channel of the engine
block, and pump the cold water
enter.
The water pump bearing and impeller are driven to rotate by the
pulley, and the
The coolant is driven by the impeller to rotate together, and is
thrown away under the action of centrifugal force
to the edge of the pump casing, while generating a certain
pressure, and then from the outlet
Outflow from water channel or water pipe. At the center of the
impeller, the coolant is thrown out
The pressure is reduced, and the coolant in the water tank is
between the pump inlet and the center of the impeller.
Under the action of pressure difference, it is sucked into the
impeller through the water pipe to realize the reciproion of the
coolant
cycle.
Water pump failure performance
1. Unstable idle speed:
The failure of the water pump can cause the rotational resistance
of the water pump to increase.
2. There will be noise in the engine part:
This sound is a rolling friive, similar to the sound of "boom boom
boom".
This sound can be accelerated as the engine rotates and changes in
volume
change. This noise generally increases with the severity of the
fault
increasingly obvious.
3. Cooling system failure
Engine water temperature is unstable:
The performance is that the engine water temperature indior needle
fluctuates within a certain range. The reason is
The water temperature in the small cycle is inconsistent due to the
lack of circulation. On the one hand, it leads to
The opening temperature of the thermostat increases, on the other
hand, after the high temperature water flows out, the low
temperature
The water quickly flows to the thermostat, causing the thermostat
to close quickly. Under normal conditions
After warming up, the water temperature of the engine will remain
at a relatively constant
level, approximately at 93°C.
