Smooth has an important influence on the fatigue life of the rolling bearing and friction, wear, temperature rise, oscillation, etc. There is no normal smoothness; the bearing can not work. Analyze the cause of the damage of the bearing; 40% of the bearing damage is smooth and smooth Badly related. Therefore; the outstanding smoothness of the bearing is a useful way to reduce the friction and wear of the bearing. In addition, the smoothness of the bearing also has the effect of heat dissipation, rust prevention, sealing, flat cushioning, etc. The smooth bearing effect can be briefly Clarified as follows:
* Form an oil film between the two tumbling surfaces or sliding surfaces that touch each other; separate the two outer surfaces; reduce the friction of the touch surface.
* When the oil is smooth; especially when the circulating oil is smooth, the oil mist is smooth and the fuel injection is smooth; the smooth oil can take away most of the friction heat inside the bearing to achieve a useful heat dissipation effect.
* When the grease is smooth, it can avoid foreign dust and other objects entering the bearing; it has a sealing effect.
* Smoothing agents have the effect of avoiding metal corrosion.
* The fatigue life of the extended bearing.

Centrifugal Pump
centrifugal pump beed used to transfer the thin liquid, like: water, diesel oil, fuel oil, gasoline etc. we have single stage centrifugal pump and multistage centrifugal pump. Multistage centrifugal pump is be used to transfer water, it's also be called boiler feed pump, pump have large flow rate and high head. single stage centrifugal pump have water pump and oil pump. CYZ series pumps is one kind of self priming centrifugal pump, it's can transporting diesel fuel oil, gasoline, kerosene etc light oil, also can be used tansport sea water, because pump have bronze imepller, it's both explosion-proof and seawater resistant. IS/ ISW/ ISG all horizonal and vertical single stage centrifugal water pump, it's be used to transfer clean cool water and hot water, also can be used to transfer sea water. we also have one good product, it's high temperature hot oil pump, this pump can be used to transfer high temperature reach to 350 degree hot oil. Simple structure, durable.
