Automotive water pump disassembly and parts introduction

1 bearing

 

In order to improve the performance of the pump, the manufacturer uses fine, low noise high-end humanized bearings.  The surface adopts high-frequency quenching heat treatment.  The surface of the bearing raceway has high hardness (wear resistance), and the heart will not lose machine strength (impact) and comprehensive performance.  For the better.

 

It meets the requirements of the pump to withstand radial and axial loads and ensures compliance with OE quality requirements.

 

2 water seal

 

Water seal is one of the basic components of water pump.  The quality of the pump directly affects the service life of the pump.  The manufacturer’s water seal adopts high strength silicon carbide rotating ring + imported graphite sintering fixed ring as the basic configuration of the first level of water seal, to ensure that the sealing performance of the pump in the operation process makes the water seal operation more and more accurate.

 

3 shell

 

The pump housing is fully molded and die-cast with rigorous process control, and the bearing holes are precision-machined.

 

Some models are heavier and thicker than competitors, and more reliable.

 

Synchronous pulley, flange

 

The components that connect the pump to the engine timing system generally include flanges, synchronous pulley, belt pulley, etc.  Manufacturers use high-strength and high-precision joint parts.

 

Ensure that it has high wear resistance and impact resistance.

 

5 the impeller

 

Common pump impellers include stamping impellers, plastic impellers, aluminum die-casting impellers, and manufacturers’ stamping impellers are made of high-quality raw materials, using their own mold production, quality is easy to control.  After stretching thicker, not easy to break or fall off.  Thousands of species have been developed.

 

Plastic impeller;  Raw materials are imported from Japan.  Conforms to OE standard, high reliability in high temperature working environment.

 

Aluminum die casting impeller;  The design has a sleeve structure, because aluminum and steel thermal expansion coefficient is different, so in high temperature operating environment, there is no high risk of falling sleeve impeller.
