The casing of the diesel engine fire pump constitutes the working chamber of the pump. The impeller, shaft and rolling bearing are the rotors of the pump. Suspension bearing parts The supporting parts support the rotor parts of the pump, and the rolling bearings are subjected to the radial and axial forces of the pump. In order to balance the axial force of the diesel engine fire pump, most pumps have sealing rings at the front and rear of the impeller, and a balance hole on the back cover of the impeller. Because some pumps have little axial force, there is no seal on the back of the impeller. ring and balance hole. The axial sealing ring of the diesel engine fire pump is composed of packing gland, packing ring and packing to prevent air intake or large water leakage.

Generally speaking, we recommend that where natural ventilation is used to install diesel engine fire pumps, there must be vents and exhaust ports of sufficient size, and the position of the vents ensures that there is enough fresh air to supply the diesel engine for combustion within the temperature limit. Of course, the water supply radiator can also be used to take away the heat of the circulating cooling water and the heat emitted from the surface of the unit. If the space cannot meet the requirements of natural ventilation and cannot effectively dissipate heat, it is recommended that you adopt forced ventilation, install an intake fan and an exhaust fan at the vent, and choose a location that can provide enough cold air for the diesel engine and take away the machine room hot air inside. Generally speaking, the air intake of the unit should be 6-7 times that of the diesel engine. Only in this way can normal ventilation be ensured and the operating efficiency of the equipment can be improved.

In addition, it must be fixed firmly so that the entire unit can be supported to ensure that the unit is in a horizontal state and absorb vibration. Generally speaking, the foundation of the unit adopts a concrete structure. The length and width are 150-250mm on one side of the length and width of the unit chassis, and the depth is 300-600mm. The height of the anchor bolts should be about twice the bolt diameter. And there should be a 750mm channel on both sides and front of the unit to facilitate the operator’s inspection and general maintenance.
