[ACRON Lecture Hall] Full Analysis of Water Pump Failure Problem!

2019-12-14

Water is an indispensable substance in the human body. People can live for 7 days without eating, but without drinking water, they can't live for up to three days. In fact, water is not only important to people, but also very important to cars, and what cars need is not ordinary water, but coolant.

When the engine is rotating, it will generate a lot of heat. If there is no coolant to cool down, the cylinder will explode in minutes or even ignite spontaneously. I don't know if my friends who live in the countryside still remember the pump we used to pump water when we planted rice in summer. The car also needs a water pump, because there is a water pump to operate the coolant.

When there is a problem with the water pump, it will affect the normal operation of the cooling system. At this time, we must consider these three questions: how to find the water pump damaged? How to repair it if it is broken? How to prevent the water pump from being damaged?

One

How to find the pump damaged?

Water leakage

A small amount of water leakage will only leave traces on the vent of the water pump; when a large amount of water leakage, we can see it directly through the water temperature and the ground of the chassis.

Reduced cycle capacity

Open the car water tank and you can see that the freezing liquid is swirling. If the whirlpool is not obvious, it means that there is something wrong with the pump and the water temperature is about to rise, especially in summer.

abnormal noise

In this case, the bearing of the water pump is generally out of the question, under the operation of the belt, there is a noise. Of course, there are slight and serious ones, so pay more attention to them at ordinary times.

pump broken how to repair?

Water Leak Repair

Generally, water pump leakage is caused by excessive wear of [water seal seat]. At this time, as long as the [water seal] is polished with emery cloth, if it is [seat], it needs to be repaired on the lathe with a reamer. Of course, if it is too serious, it can only be replaced directly.

Resolve abnormal noise

Abnormal noise generally comes from belts and bearings. If the belt is too tight, it will cause noise. At this time, you only need to adjust the belt. If it is a bearing problem, the slight is the lack of lubricating oil, or the leakage of water corrosion rust. At this time, just remove it, remove rust and lubricate it. If it is seriously broken, it can only be replaced.

Repair the impeller

Impeller damage will generally crack, corrosion and fall off, but because the impeller in the pump, to open to see. If it cracks, it can only be replaced with a new one, and if it falls off, it can be pressed directly. Corrosion shall be repaired or replaced according to the degree of corrosion.

Three

How to prevent water pump damage?

Prevention of water leakage

Water leakage is generally caused by lax sealing of the water seal and aging of the seal. Check more during maintenance. When the parts are approaching their service life, pay more attention to whether they need to be replaced.

Prevention of noise

In fact, every time you wash the car, you can ask the master to check the tightness of the belt. If there is no problem with the belt, but it still rings, remove it to see if the bearing is faulty and repair it in time. No minor problems, naturally there will be no major problems.

Prevention of impeller damage

Impeller shedding and cracking, are generally caused by installation discomfort. Because the installation method is wrong, resulting in not installed in place, the bearing will not play the corresponding role, the impeller is easier to damage, so be sure to check regularly. For cars, maintenance is more important than repair. Proper and reasonable maintenance can reduce many unnecessary repairs.
