Gravel pump efficiency is an main factor, which affected gravel pumping station efficiency. It is related with gravel pump design, manufacturing level, pump operating conditions and working conditions.
The gravel pump working point, which is an instantaneous data shows the gravel pump installed in the actual amount of water, head, shaft power and other parameters, which directly reflects the pump units ability to work. This is what should be considered in the pumping station design and management.
Accordance with the standards, gravel pump efficiency should not lower than 90% of maximum efficiency of the pump, so the pump can work efficient only in the high segment of gravel pump operating characteristic curve.
Based on the measured pressure, operational characteristics and piping characteristics from pump station, most inefficient, irrational gravel pump operating conditions were adjusted to the high segment operating point by us, thereby improving the operating efficiency of the pump.
