Diesel engine fire pumps are getting more and more attention, and the scope of use is becoming wider and wider. From the original pure water delivery to the current delivery of various domestic sewage, industrial wastewater, construction site drainage, liquid feed, etc. It plays a very important role in municipal engineering, industry, hospital, construction, hotel, water conservancy construction and other industries.

Since the operation of the electric water pump is inseparable from electricity, and the power supply is often cut off at the scene of a fire accident or the power supply is automatically closed due to a fire. Even if we are equipped with a dual power supply switching device, it is really impossible to ensure that the power grid must be normal when the fire alarm signal comes. Therefore, starting and running a diesel engine fire pump completely disconnected from the grid becomes the preferred equipment for backup fire protection facilities! The driving power of diesel engine fire pumps is completely different from that of electric water pumps, so their daily protection and treatment are also different in many places!

It can be combined with electric pumps, jockey pumps, etc. to form an automatic water fire protection water supply system, and can be linked with the fire control center.

When the pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set to start the motor to start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine to the rated speed. . The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the pump set receives a signal that the pressure of the pipeline network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.

The biggest difference between diesel engine fire pump and electric water pump is that it has its own independent power supply system – battery. Therefore, the start and operation of diesel engine fire pump will not completely depend on city power.

The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off.
