Horizontal centrifugal pump is a centrifugal pump, because of its high efficiency, wide range of performance, operational safety, environmental protection and energy saving and easy installation and maintenance features, has been widely used in urban high-level drainage , Industrial and mining drainage, process water and domestic water, etc., play an important role in people's production and life. However, in the course of using, we often need regulators flow in order to make it work better, then the horizontal multi-stage centrifugal pump adjustment methods which, the following Xiaobian will come to you one by one interpretation. Horizontal multistage centrifugal pump two kinds of adjustment Horizontal multistage centrifugal pump main adjustment methods are valve AC and frequency control two ways, as follows: It is mainly through the centrifugal pump to consume excess energy to maintain the supply, therefore Will be the first one: regulating valve throttling, which is to adjust the pump outlet valve opening, the horizontal multistage centrifugal pump speed remains the same (usually the rated speed), its essence is to change the position of the pipeline characteristic curve to change Pump operating point. This mode of operation is simple, low cost, but because it will affect the efficiency of centrifugal pumps. The second: frequency control. Due to some operating conditions deviate from the high-efficiency zone, so the need for multi-stage centrifugal pump to change speed. Compared with the valve throttling, not only energy-saving frequency control is more prominent, work efficiency, and it is conducive to reduce the possibility of centrifugal pump cavitation and largely eliminate the devastating water hammer effect, Thus greatly extending the life of pumps and piping systems.
