This series of products has high efficiency, long operating life and high reliability. The product performance meets the performance requirements and experimental methods of GB6245-2006 "Fire Pump". For liquid use with water. Under the premise of meeting the fire protection conditions, the requirements of living and production water supply conditions are taken into account. The products can be used not only in independent fire-fighting water supply systems, but also in fire-fighting and living shared water supply systems, as well as in construction, municipal, industrial and mining, water supply and drainage, ships, field operations and other occasions. The advantage is that the electric fire pump cannot be started after the power system is suddenly cut off, and the diesel engine fire pump is automatically started and put into emergency water supply.
The diesel engine fire pump is composed of a diesel engine and a fire pump. The pump group is in the form of a horizontal, double-suction, single-stage centrifugal fire pump. It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. For conveying clean water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump flow parts, the sealing form and increasing the cooling system. The new generation of products also uses a liquid crystal display. Compared with the traditional instrument monitoring, it can realize remote monitoring, which makes the modification of the operating parameters of the equipment more convenient, greatly improves the work efficiency and reduces the labor intensity of the staff. Complete performance and advanced ideas make the device far superior to other similar products.
Main Feature
1. The electric pump is the main fire pump, which can be automatically started according to the fire situation; 2. Equipped with a constant pressure pump for constant pipe network pressure; 3. The diesel engine pump is a standby fire pump, which will start automatically when there is no power supply for fire fighting; 4. Diesel engine pump starts when electric pump fails.
Working Principle
Diesel engine fire pump, the inlet and outlet are on the pump body, only need to lift the pump cover during maintenance, and the rotor parts can be moved for maintenance without dismantling the pipeline. It is very convenient. According to the needs, the diesel engine can be installed at the left end or the right end, which is convenient for on-site installation. The axial dimension of the rotor part is shortened in structure, the rigidity of the shaft is good, and the operation is more stable and reliable. There is a pump body seal ring, and the impeller seal ring is an optional condition. Working conditions: The allowable working pressure is 2.5Mpa. According to the maximum pressure of the pump casing, the pump body and pump cover are made of ductile iron (2.0Mpa), cast steel (2.5Mpa), etc. 1) Ambient temperature≤50℃, medium temperature≤80℃, 2) The weight of the medium does not exceed 1240kg/m3. 3) The liquid level must be higher than the water inlet of the pump, and idling without liquid is prohibited.
