The multi-stage fire pump of the diesel engine is located on the inlet section in the horizontal direction, and the discharge outlet is vertically upward in the water section. The lift head can increase or decrease the number of pump stages according to the needs of use. The product has advanced hydraulic models, high efficiency and wide performance range. The pump runs smoothly and the noise is low. The shaft seal is sealed by soft packing or mechanical seal. The seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick. The shaft is a full-sealed structure, ensuring contact with the medium without corrosion and long service life.
Advantage analysis of multi-stage fire pump for diesel engine:
1，Powerful: The overall crankshaft of the diesel engine unit has high rigidity, high strength and high transmission torque efficiency.
2, advanced technology: the use of international advanced technology and gantry-type body, sliding bearings, plate-fin type machine cooler, top-mounted heat exchanger, spin-on oil filter and dual cooling system.
3, superior performance: smoke, noise indicators to achieve national superior products, fuel consumption is lower than the national standard excellent products 2.1g / kW.h or more.
The multi-stage fire pump of diesel engine is installed together with the electrical instrument and other equipment. It has complete functions, high degree of automation, compact structure, automatic fault alarm and receiving start signal. It can complete the start-up procedure by itself and can quickly put into full-load operation. The unit can be equipped with damper, rubber flexible joint and exhaust port with bellows silencer as required. In the case of insufficient fuel, low battery voltage, high lubricating oil temperature, overspeed, etc., an alarm device is provided to ensure the low temperature environment of the diesel engine is started. The whole system is safe and reliable and easy to use.
4，High degree of automation: automatic, manual and fault self-checking function, monitoring the working condition in the whole process, recovering the fault restart failure automatic restart function, automatic pre-lubrication, pre-heating, making the equipment start safer and more reliable; with central control room Remote control and remote control functions, also with fieldbus connection (optional feature). The battery adopts automatic floating charge (constant current, constant voltage, turbulent charging) electric mode to ensure that the battery is in standby state at any time.
5, easy to use: equipped with remote instrumentation, can be connected to the control center according to needs, installation and use, easy maintenance.
The multi-stage fire pump of diesel engine has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long service life and convenient installation and maintenance. For transporting clean water or other liquids with physicochemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive-containing media by changing the material of the pump’s flow-through components, the form of the seal, and adding a cooling system.
