The influence of pump installation position on pump performance
The installation position of the pump has an important impact on the performance of the pump. In order to ensure the efficient and stable operation of the pump, it is necessary to reasonably select the installation position and follow the correct installation method and foundation requirements. The following is a detailed point-by-point description and summary:
1. The height of the installation position:
The installation position is too high:
Gravity limitation: When the installation position of the pump is too high, the magnitude of gravity will decrease, which will affect the water absorption capacity of the pump. When the gravity is less than the cavitation pressure, cavitation will occur, foam will be generated and the pump may be damaged.
Material limitation: The function of the pump is to transport water or other objects from a low-pressure area to a high-pressure area. If the installation position is too high, the pump needs to overcome greater gravity, so the efficiency will be reduced, resulting in more energy being wasted, and the service life of the pump will be reduced accordingly.
2. The installation position is too low:
Humid environment: The pump is installed at a low position, and water will often enter its bottom, causing the pump to be in a humid environment for a long time, which is easy to corrode the internal parts of the pump and shorten the life of the pump.
Increased maintenance difficulty: Maintenance personnel need to perform maintenance in a relatively narrow space, which increases the difficulty of maintenance and is also prone to injury.
Decreased use effect: A low installation position will increase the water inlet resistance of the pump impeller, reduce the efficiency of the pump, and reduce the output flow.
Ventilation, drainage and maintenance of the installation position:
The installation position should be selected in a place with convenient ventilation, drainage and maintenance as much as possible, and avoid installation in a narrow and closed place to avoid affecting heat dissipation and maintenance operations.
Installation method:
When installing horizontally, the inlet and outlet of the water pump are required to be horizontally symmetrical, and when installing vertically, the inlet of the water pump is required to be installed upward to avoid bubbles or debris entering the pump.
Foundation:
The water pump should be installed on a cement foundation or other solid ground, and the flatness of the foundation must meet certain standards to ensure the stable installation of the pump.
