What are the control methods of diesel engine fire pump?

“Fire-fighting gas top-pressure water supply equipment is usually composed of basic components such as air-pressure water tanks, control cabinets, top-pressure gas storage systems, and decompression release devices; in the fire-fighting state, compressed gas is charged into the air-pressure water tank to replace the fire-fighting water storage in the tank. , and always maintain the rated working pressure of fire protection, and the fixed fire water supply equipment that supplies water to the fire pipe network.”

The fire pump is part of the water supply of the fire sprinkler system and can be powered by electricity or diesel. The inlet of the pump is connected either to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). The pump supplies water at higher pressure to the sprinkler system risers and hose risers.
Fire pumps generally use three driving forces, including diesel engines, gasoline engines and electric motors. Gasoline engines are commonly used in portable fire pumps and light duty firefighting. Electric motors are the most widely used driving force for fire pumps and are both efficient and convenient.

Power surges or electrical disturbances can impact the operation of electric fire pumps. Proper surge protection measures, such as surge suppressors and lightning protection, should be in place to safeguard the electrical components of the fire pump system.
