XBC diesel fire pump can be integrated with the fire control cabinet installation, full-featured, high degree of automation, compact structure, automatic fault alarm and receive the start signal, to complete the start-up procedures, can quickly put into full load operation, and now To introduce the structure of the diesel engine fire pump features. Diesel Engine Fire Pump Diesel Engine Fire Pump Structure Description XBC diesel engine fire pump according to GB6245-2006 "fire pump" standard requirements, mainly by the pump, pump cover, impeller, shaft, seal ring, bushings, and suspension bearing components Composed of. XBC type diesel pump body and pump cover part of the pump is split from the back of the impeller, the so-called rear-door structure. Its advantage is easy to overhaul, maintenance pump body, suction line, exhaust pipe and motor, just remove the (extended) coupling coupling, you can exit the rotor components for overhaul. Pump housing (ie, pump body and pump cover) constitute the pump studio. Impeller, shaft and rolling bearings for the pump rotor. Suspension bearing component The bearing component supports the rotor part of the pump, which is subjected to the radial and axial forces of the pump. In order to balance the pump axial force, most of the pump impeller front and rear are equipped with a seal ring, and the impeller rear cover with a balance hole, due to some pump axial force is not large, the impeller is not provided on the back of the seal ring and Balance hole. Pump axial seal ring by the packing gland, packing ring, and packing and other components to prevent air or large water leakage. If the pump impeller is balanced, the cavity filled with soft packing is communicated with the inlet of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter along the surface of the sleeve. Therefore, a packing ring is installed in the packing chamber through the pump Cover the hole, the pressure of the water inside the pump lead to the packing ring for sealing. Pump impeller, such as no balance hole, because the liquid pressure on the back of the impeller is greater than atmospheric pressure, so there is no leakage problem, it can not fill rings. In order to avoid shaft wear, shaft protection is provided at the shaft through the packing chamber. O-rings are fitted between the sleeve and the shaft to prevent air ingress or leakage along the mating surfaces. Pump drive by extending the elastic coupling and the motor, the pump rotation direction, from the drive side, clockwise rotation. Import and export of the pump flange pressure by 1.6Mpa design, piping convenient.
