Introduction of the working conditions of the pump

Each pump has a performance curve, the curve is reflected in a certain speed, such as 2900 or 1450 or 800 rpm, each speed, it is not the same curve. The performance curve reflects the potential working ability of the pump itself. However, when used to play the effect of the water pump to pump outlet with pipe to bring water to the height and is not connected to the pipeline numerical spray can mark the lift pump nameplate. Then, for a specific pump system, the pump in the performance curve which point of work, which is to determine the pump operating point of the problem.
What is the pump operating point?
Pump operation refers to the actual amount of water pump operation, Q, H, N, head of shaft power efficiency n, these values are painted on the head curve and efficiency curve of power, has become a specific point, this point is called the pump operating point. The working condition of the pump reflects the instantaneous working condition of the pump.
In addition to the ability of the pump itself, the specific location of the pump operating point is also determined by other factors. There are two aspects to determine the pump operating point:
The inherent pump working ability; pump working environment, such as all the sewage pump products conveying sewage operating point is based on the calculation of the water piping system, the boundary conditions of pump and the arrangement of the pool, water level changes etc..
