How To Choose The Lubricant Of Rotary Lobe Pump

In general, when rotor pump failure occurs, lubrication failure occupies a large proportion. Therefore, for the lobe pump, the choice of lubricant is still very important, so, in daily use, how should we choose the lubricant for the lobe pump? Today Ace lobe pump's will be briefly introduced for you.

I. lobe pump operating temperature

Temperature affects the change in viscosity of the lubricant and the lubrication effect. At lower temperatures, a lubricant with a lower viscosity should be used; at higher temperatures, a lubricant with a higher viscosity is required. Depending on the ambient temperature, the viscosity of the chosen lubricant should also change.

In the kinematic viscosity: the higher the relative speed of movement of the friction surface, the lower the viscosity of the lubricant should be chosen to avoid excessive resistance to movement and excessive heat generation.

Second, the lobe pump working ratio pressure

The working specific pressure is the contact pressure per unit contact area of the friction surface. The higher the specific pressure, the greater the viscosity of the lubricant should be to avoid being squeezed out. Its structural characteristics are the smaller the gap, the higher the accuracy of the friction surface processing, the lower the viscosity of the lubricant should be.

Its environmental conditions are: when there are more serious corrosive gases in the vicinity, it is advisable to use a lubricant with high corrosion resistance.

Three, the replacement time of the lubricant

The oil level in the gear cavity should be checked through the oil sight glass before the lobe pump is started, the oil level should be in the middle of the oil sight glass and the oil in the gear cavity must be changed every one year or 5000 hours of operation.
