Introduction to the structure of automobile water pump
Centrifugal water pumps are widely used in automobile engines. Its
basic structure is composed of water pump casing, connecting plate
or pulley, water pump shaft and bearing or shaft bearing, water
pump impeller and water seal device and other parts, which are the
main components of the automobile.
Working principle of automobile water pump
- The engine drives the water pump bearing and impeller to rotate
through the pulley. The cooling liquid in the water pump is driven
by the impeller to rotate together, and is thrown to the edge of
the water pump housing under the action of centrifugal force. At
the same time, a certain pressure is generated and then flows out
from the water outlet or water pipe. The pressure at the center of
the impeller is reduced due to the cooling liquid being thrown out.
The cooling liquid in the water tank is sucked into the impeller
through the water pipe under the action of the pressure difference
between the inlet of the water pump and the center of the impeller
to realize the reciprocating circulation of the cooling liquid.
- The bearing supporting the water pump shaft is lubricated with
grease, so it is necessary to prevent the coolant from leaking into
the grease to cause the grease to emulsify, and at the same time to
prevent the leakage of the grease. The sealing measures of the
water pump to prevent leakage include water seals and gaskets. The
water seal dynamic seal ring and the shaft are installed between
the impeller and the bearing through interference fit, and the
water seal static seal seat is tightly press-fitted on the housing
of the water pump to achieve the purpose of sealing the coolant.
- The water pump housing is connected to the engine through a gasket
and supports moving parts such as bearings. There is also a drain
hole on the water pump housing, which is located between the water
seal and the bearing. Once the coolant leaks through the water
seal, it can be drained from the drain hole to prevent the coolant
from entering the bearing cavity to damage the bearing lubrication
and cause the parts to rust. If the coolant still leaks after the
engine is stopped, it indicates that the water seal has been
damaged.
