How to do a good job of cooling is to ensure that an important step in the life of the engine after automobile engine has used for a long time. The engine water pump has this important function. So drivers don’t forget to check the water pump when doing daily maintenance. Next we will provide six step for maintenance to ensure the water pump cycling successfully.
1.check the pump body and belt pulley. When they have worn and damaged, you may change a new one if it is necessary.
2.decomposition with sequential after the water pump brought out.
3.use emery cloth to grinding if the water seal has been abrasion. And use plane reamer or repair in the lathe if the water seal has any coarse scratches.
4.We can repair welding if the pump body has some damage such as not extend into the crack of bearing seat hole under 30mm, has a breaking part on the flange, has been damaged on the oil seal seat hole.
5.Ensure the water pump bearing can rotate flexible and has no abnormal noise.
6.Rotate with hand after the water pump has been assembled and ensure pump shaft has no clamping stagnation, impeller and pump shell has no rub impact. Then check the drainage volume of water pump. If there is any problem, you should check the reason and exclude.

Valve Core In The Faucet
Ordinary consumers concerns about the appearance of kitchen faucet at first when choosing the kitchen faucet. But the more important is its function and water way. It means that the key to choose kitchen faucet is faucet valve core. At present, the common valves are stainless steel spool, copper core and ceramic valve core. And the ceramic valve is widely used in daily life. Certainly it is important to know how to change the valve core. If you want to change the faucet valve core, you should loosen the screws then pull the handle at first. Then pull out the shell. Finally loosen the screws which lock switch core and take the old switch core away, installing new one on a proper position.
Stainless steel valve is one kind of valve that with high content of science and technology. But it is easy to be rust and even make pollution to the water if the steel material is not good. Copper valve is heaviest and expensive. While the requirement to copper quality is very high. Otherwise it is easy to save scale. The advantage of axle roll Faxing is that the faucet handle rotate smoothly, the operation is easy, feel comfortable, aging resistance and abrasion resistance. The ball valve handle has large angle in the area of adjusting water temperature. It can control water temperature of faucet accurately and ensure the hot water out quickly and accurately. So it will play the effect of energy saving. Ceramic valve core is the best valve core with the advantage of strong resistance to abrasion, good sealing performance, long service life and high temperature resistance.
