D-type horizontal centrifugal multistage pump has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. For transporting clean water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material and sealing form of the pump's flow-through components and adding a cooling system.
Pipeline connection precautions during installation of horizontal centrifugal multistage pump:
Horizontal multi-stage centrifugal pumps are also widely used in many fields. Because their cost is relatively low compared with multi-stage pumps, they play an important role in various industries. However, sometimes users have trouble with pipelines during installation. The choice of installation has a certain influence on the performance parameters of the pump.
After the suction and delivery pipes of the centrifugal pump of the horizontal centrifugal multistage pump are connected (as far as possible) straight, the joint surface between the centrifugal water pump and the pipeline should be ensured good air tightness, especially the water inlet pipeline, which must be strictly guaranteed There should be no leakage of water, and there should be no possibility of trapping air on the device.
Note: The suction pipe of the centrifugal pump should be installed separately for each centrifugal pump, and the pipeline of the horizontal multi-stage centrifugal pump should be as short as possible, and the number of elbows should be small to avoid sudden turns. The elbows and connecting pipes should be 90° or more, and bend. The location should be as smooth as possible and not too close to the inlet of the centrifugal water pump; the horizontal multi-stage centrifugal pump should be installed with a slight downward slope against the direction of the water flow to prevent air pockets. It is best to use a tapered eccentric reducer.
When installing the centrifugal pump pipeline, especially the inlet pipeline, the pipeline welding slag, rust and dirt should be removed. The inlet and outlet pipes of the centrifugal water pump should be fixed with brackets, and the flange of the water pump should not be broken by excessive tension, and the vibration of the horizontal multi-stage centrifugal pump caused by the vibration of the water pump pipe should also be avoided.
Flexible joints should be installed on the inlet and outlet pipes of the water pump to reduce the impact of pipe stress on the water pump and reduce the vibration transmission between the pump and the pipe.
Centrifugal pump suction pipe: when pumping water from the pool, the length of the straight pipe section in front of the suction port of the centrifugal pump should not be less than 3 times the diameter of the inlet, and the depth of the suction pipe of the centrifugal pump into the water should be greater than 1.5 times the diameter of the inlet. Less than 500mm. The distance between the suction pipe of the pump and the pool wall should be greater than 1.5 times the diameter, and the distance from the bottom of the pool should be 1.5 times the diameter and not less than 500mm, and a filter should be installed. The total product of the filter should not be less than 2 of the area of the suction pipe. One 3 times.
Horizontal centrifugal multistage pump product features:
1. Advanced hydraulic model, high efficiency and wide performance range.
2. The pump runs smoothly and has low noise.
3. The shaft seal adopts soft packing seal or mechanical seal, the seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick.
4. The shaft is a fully enclosed structure, which ensures that it does not come into contact with the medium, does not rust, and has a long service life.
