XBD-ISG, ISW type pipeline fire pump

XBD-ISG and ISW single-stage single-suction pipeline fire pumps are mainly used for pressurized water supply in fire fighting systems, and can also be used for water supply and drainage in factories and mines. It is used to transport clean water without solid particles and liquids with physical and chemical properties similar to water.

XBD-ISG (ISW) type fire pump is divided into single suction single stage and single suction multi-stage segmented two types, which are used to transport clear water without solid particles and liquids with physical and chemical properties similar to water. It is mainly used for pressurized water supply of fire fighting system, and can also be used for water supply and drainage in factories and mines. The flow range of the conveying liquid is 5～80L/s, the pressure range is 0.2～2.25MPa, the supporting power range is 1.5～200kW, and the caliber range is Ф50～Ф250mm.

Features:

1. The pump is compact in structure, small in size, and beautiful in appearance. Its vertical structure determines the installation area is small, and its center of gravity coincides with the center of the pump foot, thus enhancing the stability and service life of the pump.

2. The suction port and discharge port of the pump are both horizontal, simplifying the connection of the pipeline.

　　3. The multi-stage type can be installed according to the needs, and the suction port and the discharge port can be installed in the same direction or 90. , 180. , 270. Several different directions to meet different connection occasions.

　　4. The pump pressure can be satisfied by increasing or decreasing the number of pump stages and cutting the outer diameter of the impeller as required, without changing the installation area, which is not available in other pumps.

　　 5. The pump rotor has a small winding, stable operation, low vibration, low noise and long service life.

Use range:

　　 XBD—ISG (ISW) type fire pump is mainly used for pressurized water supply in pipelines of fire fighting system. It can also be applied to industrial and urban water supply and drainage, high-rise buildings pressurized water supply, long-distance water supply, heating, bathroom, boiler cold and warm water cycle pressurized air conditioning refrigeration system water supply and equipment supporting occasions.

Structural features:

　　 XBD-ISG (ISW) single-suction single-stage fire pump is composed of a motor and a pump. The pump and the motor are coaxial. The pump structure includes pump body, impeller, pump cover, mechanical seal and other components. The pump inlet and outlet are on the same horizontal axis, and the caliber specifications are the same, the installation and unloading are extremely convenient, and the floor space is small. The pump is equipped with a mounting base, which is easy to install and increase the stability of pump operation. The pump seal adopts mechanical seal, which has the characteristics of reliable seal and no leakage. The axial force of the pump is balanced by a balance ring set on the impeller. The inlet and outlet flanges of the pump are according to 1.6MPa, and the pipeline is convenient to match.

XBD—ISG (ISW) single-suction multi-stage segmented fire pump consists of two parts: a motor and a pump. The motor is a Y-type three-phase asynchronous motor. The pump and the motor are connected by a coupling. The whole is a rigid connection, so there is no need to use it. Correction. The pump consists of a stator part and a rotor part. The pump stator part is composed of water inlet section, middle section, guide vane, water outlet section, stuffing box body and other parts. In order to prevent the stator from being worn out, the stator is equipped with a sealing ring, balance sleeve, etc., which can be replaced with spare parts after being worn out. The rotor part is composed of shaft, middle wheel, balance drum and so on. The lower end of the rotor is a water-lubricated bearing, and the upper part is an angular contact ball bearing. Most of the axial force of the pump is borne by the balance drum, and the remaining small part of the residual axial downward force is borne by the angular contact ball bearing. The joint surface of the water inlet section, middle section and water outlet section is sealed with paper pads by tightening, and users can choose according to their needs.
