Product Description
Xbd-SJ vertical long shaft pump for fire fighting is designed and developed by absorbing the advanced experience in the design and manufacture of vertical long shaft pump at home and abroad, which can be used for fire fighting water supply. XBD - SJ vertical long axis of the fire pump of the pump body consists of center of revolving and pump body of two parts, mechanical energy produced by motor drives the pump shaft, impeller on the pump shaft rotation, after gaining energy flow through the impeller vane conversion direction, the space along the flow between inside and outside the tube, vertical rise, the water pipe into horizontal flow, The pump has the advantages of small installation area, can dive into the water operation and so on, in the fire water is not convenient, can pump the river water, lake water and so on, very convenient.
Xbd-SJ vertical long shaft fire pump suction inlet vertical downward, horizontal outlet, no vacuum pumping, no water diversion start, single foundation installation, water pump and motor directly connected, the foundation covers a small area; Looking down from the motor end, the pump rotor parts rotate counterclockwise, the main features are:
1. Xbd-SJ vertical fire protection long-shaft pump adopts hydraulic design software to optimize the design, with superior performance, and fully considers the abrasion resistance of impeller and guide vane body, so that the service life of impeller and guide vane body and other parts is greatly improved; The products run smoothly, safe and reliable, high efficiency and energy saving.
2. The inlet of XBD-SJ vertical fire fighting long-shaft pump is equipped with filter screen, and the opening size is appropriate, which not only effectively prevents the large particle impurities from entering the pump and damaging the pump, but also greatly reduces the inlet loss and improves the pump efficiency.
3. The impeller of XBD-SJ vertical fire long-shaft pump adopts balance hole to balance the axial force. The front and rear covers of the impeller are provided with replaceable sealing rings to protect the impeller and guide vane body.
4. Xbd-SJ vertical fire long shaft pump intermediate shaft, hoist pipe and guard pipe are multi-joint, the shaft is connected by threaded coupling or sleeve coupling; The number of water pipe can be increased or decreased according to user needs, to adapt to different depth of liquid, impeller and guide vane body can be customized according to user's design head and requirements for single stage or multistage, to ensure that can meet various user needs.
5. The length of single shaft of XBD-SJ vertical fire fighting long shaft pump is reasonable, with strong stiffness and sufficient hardness.
6. The XBD-SJ vertical fire fighting long shaft pump pipe is connected with flange, and there is a guide bearing body between two adjacent lifting pipes. Guide bearing body and guide vane body are equipped with guide bearings, guide bearings made of polytetrafluoroethylene or Cyron, nitrile rubber and other polymer materials. The guard pipe is used to protect the shaft and guide bearing. When conveying clean water, the guard pipe can be cancelled, and the guide bearing does not need to be externally connected with cooling and lubricating water. When transporting sewage, the guard pipe must be installed, and the guide bearing must be externally connected with cooling and lubricating water (the water pump is equipped with a self-closed sealing system, and the self-closed sealing system can prevent sewage from entering the guide bearing after the water pump is stopped).
7. The residual axial force of XBD-SJ vertical fire long-shaft pump and the weight of rotor parts can be borne by the thrust bearing in the motor support or the motor with thrust bearing. Thrust bearings are lubricated by grease (also known as dry oil lubrication) or lubricating oil lubrication (also known as thin oil lubrication).
8. Xbd-SJ vertical fire long-shaft pump packing box is unpacking packing box independently designed by our company, which is convenient for later maintenance and replacement.
9. The shaft seal of XBD-SJ vertical fire long-shaft pump is a packing seal, and the shaft seal and guide bearing are equipped with replaceable bushings to protect the shaft. The axial position of the impeller is adjusted by the upper end of the thrust bearing component or the adjusting nut in the pump coupling, which is very convenient.
