What is the working principle and model meaning of pipeline pump?
Pipeline pump has become one of the commonly used booster pumps in industrial applications. Pipeline pump is mainly used in HVAC cold and hot water circulation, industrial urban water supply and booster water supply for high-rise buildings. For its working principle and key points of use, Longyang Pump Valve will take you to introduce the working principle of pipeline pump, the meaning of pipeline pump model and the key points of use, so that you can clearly understand the pipeline pump and how to use it.
Working principle of pipeline pump
The pipeline pump can send water out because of the centrifugal force. Before the pump works, the pump body and the inlet pipe must be filled with water to form a vacuum state. When the impeller rotates rapidly, the blade drives the water to rotate quickly. The rotating water flies away from the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum region. Under the action of atmospheric pressure (or water pressure), the water from the water source is pressed into the inlet pipe through the pipe network. In this way, continuous pumping can be realized.
It is worth mentioning that the pipeline pump must be filled with water in the pump casing before starting, otherwise the pump body will be heated, vibrated, the water output will be reduced, and the pump will be damaged (referred to as “cavitation”), resulting in equipment accidents! There are many types of pipeline pumps, and the common classification methods are as follows: 1. According to the impeller suction method, it is divided into vertical pipeline pump, horizontal pipeline pump, multistage pipeline pump and hot water pipeline pump. According to impeller structure: open impeller centrifugal pump semi-open impeller centrifugal pump closed impeller centrifugal pump. According to working pressure: low-pressure centrifugal pump, medium-pressure centrifugal pump, high-pressure centrifugal pump, vertical centrifugal pump.
