Rotary Lobe Pump Efficiency Factors Affecting The Introduction

The rotor pump is a volumetric pump that is now widely used in the treatment industry for domestic sewage, municipal sludge, high viscosity liquids and even solid-liquid two-phase flows due to its simple mechanism, long service life and simple maintenance. So, what factors affect the efficiency of a lobe pump during operation, today Ace lobe pump's will introduce you to them.

1. Mechanical losses

The mechanical losses, also called disc losses, are mainly friction losses between the liquid and the outer surface of the front and rear cover plates of the impeller and the rotary lobe pump cavity.

2. Volume loss

Part of the impeller's liquid leaks back to the impeller inlet through the impeller seal ring gap and is not used effectively, forming a loss. Therefore, the clearance of the sealing ring should be as small as possible, but due to processing and assembly, etc., too small a clearance may form bias grinding or jamming, and the national standard has made special provisions for the clearance of various types of rotary lobe pumps.

3、Hydraulic losses

rotary lobe pump over-flow part (from the inlet to the outlet) of the fluid is bound to have losses caused by changes in velocity size and direction, these two parts are the hydraulic losses. To reduce this loss, in addition to improving the finish of the over-flow parts, try to use an excellent hydraulic model.
