Horizontal centrifugal multistage pump pipe connection points for attention in installation process

Type D horizontal centrifugal multistage pump with high efficiency, wide range of performance, smooth running safety, low noise, long service life, easy installation and maintenance, etc. For conveying water or physical and chemical properties similar to water other liquid. Can also by changing the pump flow components, sealing material form and increase the cooling system used in conveying hot water, oil, corrosive or abrasive media.

horizontal centrifugal multistage pump pipe connection points for attention during installation:

horizontal multi-stage centrifugal pump is also used very widely in many areas, because of its cost is relatively low compared with multistage pump, were plays an important role in various industries, but sometimes the user during the installation process the choice of pipeline installation of pump performance parameters have certain influence.

horizontal centrifugal multistage centrifugal pump suction and delivery pipe ( As far as possible) Straight after the connection, the combination of centrifugal pump and piping between surface, should guarantee the good air tightness, suction culvert, in particular, must strictly to ensure no leakage, and on the device should be no nest full of air.

note: centrifugal pump suction pipe as far as possible each centrifugal pump installed separately, and horizontal multi-stage centrifugal pump pipe road as short as possible, less number of elbow, avoid sudden turn, elbow and connecting pipe to use greater than or equal to 90 °, bend round as far as possible, and don't get too close to the centrifugal pump inlet; Horizontal multi-stage centrifugal pump suction horizontal section slightly downward inclined pipe installation should be under flow direction, to prevent WoQi, it is best to use conical eccentric reducer.

centrifugal pump pipe installation, especially import pipe, the pipe welding slag, rust and dirt should be removed. Centrifugal pump in and out of the water piping should be fixed bracket, should not make the pump flange by excessive tension fracture, and also to avoid the pump pipeline vibration cause the vibration of the horizontal multi-stage centrifugal pump.

should be on the road at the inlet and outlet pipe of pump installation of flexible joint, to alleviate the stress effect on the water pump and pipeline to reduce vibration transmission between pump and pipeline.

centrifugal water pump suction line: if the pumping water from a pool of water, the straight pipe in front of the centrifugal pump suction length should not be less than three times the diameter of the entrance, centrifugal pump suction nozzle immersion depth under the surface should be greater than 1 the diameter of the entrance. Five times and not less than 500 mm. suction mouth have thrown away from the wall distance is greater than 1. Five times the diameter, the distance from the bottom should be in 1. Five times the diameter and no less than 500 mm, and should be added a mesh, mesh and product should not be less than the suction mouth area of 2 a 3 times.

horizontal centrifugal multistage pump product features:

1, the advanced hydraulic model, high efficiency and wide performance range.

2, pump smooth operation, low noise.

3, shaft seals use soft packing seal or mechanical seal, safe and reliable sealing, simple structure, convenient maintenance.

4, shaft seal structure for the whole, to ensure that the no contact with the media, no corrosion, long service life.
