Speed of ZYB hard tooth surface slag oil pump

How to select the rotating speed of ZYB type hard tooth surface slag oil pump, 1450r / min and 960r / min. it is necessary to understand the service conditions of the pump in detail as much as possible. In addition to the operating parameters, such as flow and pressure, the characteristics of the conveying medium, such as the corrosivity of the medium, steam content, the ratio of solid solution and the size of solid particles, as well as the working temperature, viscosity and specific gravity of the medium, We should understand the corrosivity of materials, suction conditions and installation conditions of pump device. According to our experience, the following points should be paid attention to in the selection of ZYB hard tooth surface slag oil pump:

Selection of rotating speed of ZYB hard tooth surface slag oil pump:

1.1. Determine the speed range according to the viscosity of the conveying medium and the specification of the pump:

When conveying high viscosity medium, the pump should select low speed. If the viscosity is low, the corresponding high speed can be selected:

1) When the medium viscosity is > 20 ° e, for large-size ZYB type hard tooth surface slag oil pump (the outer diameter of the main rod is more than 60mm), the speed should be 970rpm or 720rpm. If the viscosity is higher (viscosity > 80 ° E) such as viscose, the speed can be reduced, and 200-500rpm is recommended;

2) For small-size ycbzyb hard tooth surface slag oil pump, when the medium viscosity is > 20 ° e, the speed should be 1450rpm or 970rpm. If the viscosity is higher (viscosity > 80 ° E), the speed can be reduced, and 300-600rpm is recommended;

1.2. The higher the speed of the pump, the smaller the volume of the pump under the same performance parameters. However, due to the high speed and high friction power, the wear of the pump will be large and the service life will be short. If the lubricity of the transmission medium is poor or contains trace impurities, the lower speed should be selected to maintain a long service life of the pump, which is recommended to be below 1450rpm.

According to the characteristics of price and quality, the ZYB slag oil pump has made corresponding improvements in the structure, material of main parts and shaft end seal, so that the ZYB slag oil pump is more suitable for specific media. In use, the service life of the heavy oil pump produced by Xinghe pump is more than 10 times that of the same general heavy oil pump.

ZYB hard tooth surface slag oil pump consists of pump body, pump cover, gear, shaft seal, gland, etc. the pump has the advantages of high pressure, good performance of conveying residue and waste oil, hard tooth surface, special treatment and torque resistance.
