Silent diesel engine water pump unit

1Silent diesel engine water pump unit product overview

The silent diesel engine water pump unit is a new series of products developed by introducing and absorbing foreign low-noise diesel engine fire water pump technology. Silent diesel engine water pump units are widely used in places with strict environmental noise requirements, such as postal and telecommunications, hotel buildings, entertainment venues, hospitals, shopping malls, and industrial and mining enterprises, as emergency firefighting and domestic water supply.

II Silent diesel engine water pump unit Product features:
1. The noise index for one meter distance measurement can reach 85dB (A), and the unit can be used without reducing power;
2. The overall design of the silent diesel engine water pump unit is compact in structure, small in size, and has a novel and beautiful appearance;
3. Vibration isolation design, high-performance shock absorbers are used between the diesel engine and water pump and the common base to reduce noise sources;
4. The soundproof cover made of high-efficiency sound-absorbing materials has good sound absorption and insulation capabilities;
5. The use of impedance and sound absorption composite mufflers reduces the noise during exhaust emissions;

6. Efficient noise reduction type with multiple intake and exhaust channels, ensuring sufficient power performance of the unit;
7. Large capacity fuel injector;
8. Specially designed quick opening cover plate for easy maintenance and upkeep.

4Silent diesel engine water pump unit Advantages of silent diesel engine water pump unit:
1. Automatic start: The diesel water pump unit can automatically start and operate at full load within 5 seconds after receiving a fire alarm/pipeline pressure/power outage/or other start signals;
2. Automatic charging: The battery can be charged automatically by the mains power or diesel engine charging motor to ensure the smooth start-up of the unit;
3. Automatic alarm: It automatically alarms and protects against faults such as low oil pressure and high water temperature in diesel engines, and alarms and shuts down when overspeed occurs;
4. Automatic preheating: put the diesel engine in a hot standby state to ensure emergency operation;
5. Direct connection: Diesel water pump units below 360kw adopt the technology of direct connection between diesel engine and water pump through elastic coupling, which reduces the number of fault points and greatly shortens the starting time of the unit, increasing the reliability and emergency performance of the unit.
