Difference of centrifugal oil pump and centrifugal pump

Centrifugal  oil pump

1. In order to control temperature effect on the pump shaft, pump body support required installed in the center, so when the conveying high temperature oil can avoid due to thermal expansion and the pump eccentric or stuck phenomenon, on the other hand, in the bottom of the pump installation and positioning guide sliding  

 2. The seal device with packing seal and mechanical seal. The longer length of the general packing room, some on the packing gland equipped with a water seal, but most choose to seal device, so you can better protect the pump, such as oil seal device can seal lubrication and cooling, and can avoid the metal collision sparks, gland seal device of the circle usually have arranged a copper ring.  

 3. Packing box, bearings, bearings are generally equipped with cooling structure for cooling  

 4. Oil is flammable, in order to prevent the fire, the original motive is mostly used explosion-proof motor  

 5. According to the transmission fluid temperature and the corrosion degree is different, the pump cover, the pump body and the impeller and so on main parts are divided into three kinds:  

 First class: cast iron, corrosion, temperature 20~+200 c;  

 Second class: cast steel, corrosion, temperature 45~+400 c;  

 The third category: alloy steel, corrosion resistance, the use of temperature - 45~+400;
