What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?
Pump downstream equipment design pressure is greater than 3MPa, if it is 400 meters, the downstream equipment design pressure is greater than 4MPa
The dead point head is the measured head after the outlet valve is closed. Mainly on the lower reaches of the pump equipment, such as your dead center, the lift is 300 meters, that is, 3MPa
In a dead head will be relatively high, the main downstream equipment and pump, if a dead head high, so the design pressure of the pump needs downstream equipment will be relatively large, resulting in the cost increases, so close a better head lower dead point.
Should shut down the valve bar, reduce the flow to increase the point of the head, it is best to adjust within the best range of work, otherwise it is easy to cause the current is too large, burning the motor
