XBF Diesel Engine Fire Pump Set Control System 2900r/min For Industrial And Mining

1. The electric pump is the main fire pump and can automatically start according to the fire situation;
2. Equipped with a stabilizing pump to maintain a constant pipeline pressure;
3. The diesel engine pump is a backup fire pump that automatically starts when there is no power supply for firefighting;
4. When the electric pump malfunctions, the diesel engine pump starts.

The XBC diesel engine fire pump set is mainly used for boosting water supply in fire protection system pipelines. It can also be applied to industrial and urban water supply and drainage, high-rise building pressurized water supply, long-distance water supply, heating, bathroom, boiler cold and warm water circulation pressurized air conditioning refrigeration system water supply and equipment matching, and other occasions.

The XBC diesel engine fire pump set is mainly composed of pump body, pump cover, impeller, shaft, sealing ring, shaft sleeve, and suspension bearing components according to the standard requirements of GB6245-2006 "Fire Pump".

The pump body and pump cover of XBC diesel engine pump are divided from the back of the impeller, which is commonly known as the rear opening structure. Its advantage is that it is easy to maintain. During maintenance, the pump body, suction pipeline, discharge pipeline, and motor do not need to be moved. Only the middle connecting piece of the (extended) coupling needs to be removed to exit the rotor components for maintenance.

The pump casing (i.e. pump body and pump cover) constitutes the working chamber of the pump. The impeller, shaft, and rolling bearings are the rotors of the pump. The suspension bearing components support the rotor components of the pump, while the rolling bearings are subjected to radial and axial forces from the pump.

In order to balance the axial force of the pump, most pumps are equipped with sealing rings at the front and rear of the impeller, and balance holes are provided on the rear cover plate of the impeller. Due to the low axial force of some pumps, there are no sealing rings or balance holes on the back of the impeller.
