Diesel engine fire pump unit

Product Overview:
The diesel engine driven fire pump set is designed and manufactured in accordance with GB "Fire Pump". Complies with CCCF certification requirements. The advantage of the product is that in the event of a fire, if the power supply fails and the electric fire pump unit cannot be put into use normally, the diesel fire pump unit can automatically put into operation to ensure the normal operation of fire extinguishing. Compared with electric fire pump units, the second advantage is that there is no need for long-term investment in power supply, saving on mains power transformers and normal expenses. The diesel engine fire pump unit is equipped with various automatic functions to meet customer usage requirements, ensuring that the equipment is in a normal standby state for a long time and can be put into firefighting work at any time. This diesel fire pump set is also suitable for various emergency standby pump situations
Main characteristics of diesel engine pump group:
·Automatic operation: When the diesel engine fire pump unit receives a valid fire signal and a remote control start signal, the unit will automatically start running. When the power supply system of the electric motor fire pump unit loses power and signals a phase loss, the unit will automatically enter a special machine state. The diesel fire pump set will start for 10 seconds, but if it cannot start and run, it will stop for 10 seconds before restarting. The unit will automatically repeat three times
·Automatic charging: When using mains charging in the automatic position and in standby mode, if the battery voltage is low, the unit will automatically charge. When the battery voltage is sufficient, it can automatically stop charging to avoid damaging the battery
·Automatic alarm: multiple failed start alarms, diesel engine low oil pressure alarm, diesel engine water temperature ultra-high alarm, diesel engine ultra-high speed alarm and shutdown, battery low voltage alarm, charging failure alarm, fuel shortage indication alarm, etc
·Automatic preheating: Put the diesel engine in a hot standby state to ensure emergency operation;
·Direct connection: The diesel water pump unit below 360kw adopts the domestically pioneered technology of direct connection between the diesel engine and the water pump through elastic couplings, reducing the number of fault points and greatly shortening the starting time of the unit, increasing its reliability and emergency performance
·Users can also request to set other alarm outputs (non-standard supply)
·Equipped with telemetry, remote signaling, and remote control functions (non-standard supply)
·Wide range of types: Fire pump sets can choose single-stage single suction pumps, multi-stage single suction pumps, single-stage double suction pumps, etc. The use of multiple pump combinations in parallel, with a wide range of flow and pressure
