Common failures of water pumps


Recommended Posts

 

It is unavoidable that the breakdown of the automobile water pump is in use. Common faults are as follows:

(1)   Bearing locking and fracture

The causes of bearing failure may be the following aspects: bearing itself quality defects; bearing excessive impact load; product structure design defects; improper pump installation (such as knocking installation, belt tension, etc.)

(2)   Leakage of installation surface

The possible reasons for leakage of installation surface are as follows: uneven application of sealant, resulting in leakage of seam; improper installation of sealing gasket; leakage of pump sealing gasket or improper installation operation.

(3)   Impeller damage

Impeller damage is common in the form of impeller cracking, impeller loose from the pump shaft or impeller corrosion, impeller corrosion will not generally cause engine failure. When the impeller cracks or the impeller is loosened from the pump shaft, the coolant circulation speed becomes slower, which may easily cause the engine temperature to be too high. Damaged impeller may also impact the pump housing when rotating, causing cracking.

If your car water pump is broken down , Feilong water pump can give you the prompt help.

      According to the different driving mode, the pump is generally divided into mechanical pumps and electric pumps. Most of the engines now use mechanical pumps, and electric pumps have been used in some newly developed, technologically high engines, such as the BMW 6-series (E63) engine.
      (1)Mechanical pumps
          The mechanical water pump is driven by the engine crankshaft through the driving tape, and its rotational speed is proportional to the engine speed. The working methods of mechanical pumps have both advantages and disadvantages. When the engine is working under high speed and heavy load conditions, the heat produced by the engine, the high speed of the pump makes the circulating flow of the coolant increase, so that the cooling capacity of the engine can be improved. When the engine is working under low speed and heavy load, such as traction other vehicles or open air conditioner, the engine speed is low and the speed of pump is low. , which lowers the engine's cooling capacity.
      (2)Electric pumps
          Electric water pump has brushless electric pump and brush electric pump. The electric pump is controlled by the engine control unit through the current, which is not affected by the engine speed, and can be flexibly operated according to the actual cooling of the engine. Because the electric pump consumes very little engine power, the fuel consumption of the engine can be reduced after the electric pump is used.
