Structure of water pump
 
The water pump used in automobile engine is centrifugal water pump, which consists of shell, impeller, bearing, pump shaft, water seal and transmission belt wheel.
 
(1) water pump housing is made of cast iron or cast aluminum.
The wall of cast iron case is thick and its quality is large. With the improvement of the requirement of engine lightweight, only some large engines of commercial cars are still using the pump of cast iron case.
Many cast iron cases also have some water channels and thermostat installation rooms, which further increase the weight of the case.
Most water pumps in cars use cast aluminum shells, and the size of the shells is getting smaller, many of the shells no longer have the function of water channels.
(2) the impeller of the impeller pump is made of metal or engineering plastics, such as cast iron. The impeller is made of semi-circular arc, double circular arc or multi-circular arc blades that bend backwards.
Pump impeller made of cast iron is of high quality, but its mechanical strength is high.
The plastic impeller is easy to realize miniaturization and lightweight, and has good corrosion resistance and easy shape processing. Therefore, more and more car engine pumps use plastic impeller.
                 
 
(3) bearing water pump bearing is an important part of water pump, and the failure of a considerable part of water pump is caused by the damage of water pump bearing.
As the engine gradually develops towards high power, the pump bearing needs to have higher thermal stability, greater bearing capacity and better sealing, so some automobile pumps use axial bearing.
Shaft bearing is actually a kind of double supported bearing with simplified structure. Two supporting bearings have no inner ring. The raceway of the rolling body is directly processed on the pump shaft.
Under the same bearing capacity, the size of shaft bearing is smaller than that of general type bearing.
Under the condition of the same size, the bearing capacity of shaft bearing is greater than that of general type bearing.
 
(4) pump shaft pump shaft is generally made of forged steel.
The pump impeller is installed on one end of the pump shaft, which is supported on the pump housing by bearing.
The other end of the pump shaft is equipped with a transmission belt wheel, which is driven by the engine crankshaft through toothed tape or v-shaped tape.
 
(5) water seal is used to seal the cooling fluid so as to avoid leakage. Meanwhile, the cooling fluid is separated from the pump bearing to protect the bearing.
At present, two-layer ceramic water seal has been widely used in water pumps. Two ceramic water seals installed on the same axis are pressed together by a spiral spring.
Compared with rubber water seal, ceramic water seal is more wear-resistant and has a longer service life, but it is also prone to abrasion by hard particles in the cooling fluid.
Although the processing of water seal has been improved continuously, water seal damage caused water pump leakage is still the main reason for water pump damage.
 
(6) according to the tooth shape of the belt, the belt wheel can be divided into toothed belt wheel and v-shaped belt wheel.
With less and less transmission tape on the engine, more and more pumps share one toothed belt drive with generators, air conditioning compressors, steering pumps, etc. Therefore, more and more toothed transmission belt wheels are added.

Measures to improve the anti cavitation performance of centrifugal pumps First, improving the geometry of the inlet of the impeller 1. use double suction impeller 2. the lower inlet velocity of the impeller 3. enlarging the width of the entrance edge of the blade B 4. the proper selection of the number of blades and the angle of the punching Second, the use of anti cavitation material Generally speaking, the higher the material surface temperature and toughness, the higher the hardness and chemical stability, the better the cavitation resistance of the parts. Third, improve the anti cavitation performance of the pump with the induction wheel The inducer can improve the cavitation performance of the pump before the impeller of the centrifugal pump, and the effect is remarkable.   Chongqing Feilong Jiangli Auto Parts welcome you to discuss this topic with us. 

So I had some problems with slippage during some of the hot days. Bought this 2014 chevy equinox AWD used with about 90k on it and I guess the tranny was never serviced. Drained and refilled the fluid in the transmission, which was only about 4 quarts or so (need to flush to get it all) and it was black. Did it again in a week or so to mix in some good fluid. Car ran alright but instead of a slippage, it started to develop a hard shift. Next day, started to drive it and it would all of a sudden rev out like its in neutral. Coasted the car to the side of the road and moved the shifter, but would not engage into drive or reverse. i shut the car off and restarted and then it would go into drive (electronic control) but after a few feet it would pop back into a neutral state with the shift indicator in drive. No codes, no lights. 

Fixed this and all good!
