In the past, the river pump had not been the spare part of the automobile engine. At that time, the used medium for that liquid cooling is pure water. Sometimes, in order to avoid the freeze, slightly methanol would be added. The circulation on the cooling water completely been dependent on the natural phenomenon namely heat convection. Following the cylinder absorbed the center, the cooling water would naturally flow upward and enter the top of the radiator. If the cooling water became cold, water would naturally sink towards bottom of the radiator and type in the under-area of the cylinder block. On the basis of this principle, the cooling task can be finished. However the development of the technology, water pump is put into the engine cooling system to make the cooling water flow more quickly. Presently the centrifugal water pump is often used in the air conditioning in the automobile engine. The most appropriate installation position for that pump is the bottom with the air conditioning. However, nearly all of this pump is set up in the centre of the air conditioning and a few are positioned in the top with the engine. There exists a fault for the pump which is positiioned in the most notable from the engine. It easily ends up with the cativation. No mater the spot that the pump is, its water amount is very large. On the perspective and services information life, the largest change because of this pump is its ceramic seal component. Weighed against the rubber or leather seal component, the ceramic seal might be more wear-resistant, but it is easily abraded with the hard particle inside the cooling water. Although a lot of measures are arrive at steer clear of the problems with the pump seal, currently these problems can not be solved completely. Once the seal has the leakage, the lubrication on the water pump bearing will probably be washed out. In the past 20 years, the durability of the auto has been improved greatly. Can the service lifetime of this pump be prolonged? It really is challenging to answer the question. You can still find lots of jobs that needs to be prepared for the lake pump. In most cases, the fault diagnosis of water pump is actually comparatively easy. When the air conditioning is suffering from the leakage, people can smell the odor on the anti-freeze fluid. But people should further inspect it again and investigate whether there exists leakage within the water Pump Seal. Water leakage would be the main problem for that water pump. The noise will be the second problem. Then is water leakage or noise, the radiator will probably be damaged. In the word, it is of great essential to maintain your water pump regularly.
