Product Brief
The fire pump set driven by diesel engine shall be designed and manufactured in accordance with GB fire pump. Meet CCCF certification requirements. The product has the advantages that when a fire occurs, the power supply fails, and the electric fire pump group cannot be put into use normally, the diesel engine fire pump group can be put into operation automatically to ensure the normal fire fighting. Compared with the electric fire pump group, it has two advantages: no need for long-term investment in power supply, saving the municipal power supply transformer and normal expenses. The diesel engine fire pump set is equipped with various automatic functions to meet the customer's use requirements, to ensure the long-term normal standby state of the equipment, and to put the fire fighting work at any time.
The diesel engine fire pump set is also suitable for various emergency standby pump occasions.

Scope of application:
1. The purpose of various fire hydrants and sprinkler main pumps.
2. It is suitable for all kinds of fire booster and pressure stabilizing pump occasions.
3. Various villas, communities and other fire protection systems.
4. Fire water system of industrial and civil buildings.
5. It is suitable for various oil depots, oil loading and unloading terminals, logistics parks and other occasions with high fire protection requirements.

6. The maximum allowable medium temperature is 70 ℃, and the maximum ambient temperature is 40 ℃
7. The maximum allowable working pressure is 1.6Mpa, and the maximum inlet pressure is 0.6MPa.
Main features of diesel pump set:
1. Automatic operation: when the diesel engine fire pump unit receives the effective fire signal and remote control start signal, the unit will start automatically. When the power supply system of the motor fire pump unit is cut off to form the signal of phase loss, the unit will be in special state automatically. If the diesel engine fire pump set starts for 10s and fails to start, it will stop for 10s and then restart. The unit will automatically repeat three times;
2. Automatic charging: the unit will be charged automatically when the battery voltage is low when the battery is in standby mode at the automatic position. When the battery voltage is sufficient, the charging can be stopped automatically to avoid damage to the battery;
3. Automatic alarm: multiple start failure alarms, diesel engine low oil pressure alarm, diesel engine water temperature alarm, diesel engine ultra-high speed alarm and shutdown, battery low voltage alarm, charging failure alarm, fuel lack indication alarm, etc.
4. Automatic preheating: keep the diesel engine in hot standby state to ensure emergency work;
5. Direct connection: the diesel water pump unit below 360kw adopts the technology of direct connection of diesel engine and water pump through elastic coupling, which is the first in China. It reduces the failure point, greatly shortens the starting time of the unit, and increases the reliability and emergency performance of the unit;
6. The user can also request to set other alarm output (non-standard supply);
7. It has telemetry, remote signaling and remote control functions (non-standard supply);
8. Wide range of type spectrum: single stage single suction pump, multi-stage single suction pump, single stage double suction pump, etc. can be selected for the fire pump set. Or a variety of pump combinations in parallel, wide range of flow, pressure.
How to select type
1. The rated power of the selected diesel engine shall be greater than 10% of the maximum shaft power of the water pump. Under abnormal conditions, the power of the diesel engine will not reach the rated power. In order to ensure normal operation, it is necessary to select a high-power diesel engine and water pump. Note the rated power of diesel engine is measured under the following standard conditions;
2. The ambient atmospheric pressure is 100KPA.
3. Ambient temperature 25 ℃.
4. Air relative humidity 30%.
5. When the altitude of the working place is increased by 100m, the power will be reduced by 3%.
