Why are fire pumps necessary?

Jockey pumps should be inspected regularly, with routine checks typically performed monthly. The inspection includes checking pressure settings, verifying proper operation, and inspecting for any leaks or damage. Ensuring that the jockey pump functions correctly helps maintain system pressure and prevent unnecessary wear on the fire pump.

Jockey pumps are smaller pumps that maintain pressure in the fire protection system between tests and activations. They prevent pressure loss in the system and ensure that the fire pump doesn’t start unnecessarily. Jockey pumps are crucial for system reliability.

All places need to be equipped with fire-fighting facilities, and fire pumps are necessary water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between the two is The electric fire pump needs to be supplied by the power system. If the power is cut off, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

A fire pump is a critical component of a fire sprinkler system, providing the necessary water pressure to ensure the sprinkler system works properly. Fire pumps are usually powered by electric motors or diesel engines and they come in centrifugal, turbine, or rotary types.

To ensure that the fire pump is working properly, it is important to maintain and test it regularly. Regular maintenance tasks include inspecting the motor and fuel system, changing the oil, and checking the battery. Testing the pump pressure and flow rate should also be done on a regular basis. If any issues are found, it is important to contact a professional for assistance. A trained technician should also inspect the fire pump annually.

The lower the pumping head of the fire pump, the smaller the motor load. Under the misleading of this kind of misunderstanding, when purchasing a water pump, the head of the water pump is often selected to be very high. In fact, for centrifugal water pumps, when the pump model is determined, the power consumption is proportional to the actual flow of the pump. The flow rate of the water pump will decrease with the increase of the head, so the higher the head, the smaller the flow rate and the smaller the power consumption. Conversely, the lower the lift, the greater the flow and the greater the power consumption. Therefore, in order to prevent the motor from overloading, it is generally required that the actual pumping head of the pump should not be lower than 60% of the calibrated head.

Fire sprinkler systems are an important part of life safety in buildings. International building codes allow some exceptions when buildings are “fully watered”, such as reducing rated spacing, reducing hydrant flow requirements, increasing exit travel distance, and increasing building height and area. These exceptions are allowed so that in the event of a fire, the sprinkler system will suppress the fire enough that occupants can safely evacuate the building and that the spread of the fire is contained before the fire department has fully arrived to extinguish it.

The basis for the selection of fire pumps should be based on the process flow, water supply and drainage requirements, and be considered from five aspects, namely, liquid delivery volume, device lift, liquid properties, pipeline layout, and operating conditions. Fire pumps are mainly divided into vertical and horizontal types. The flow rate of the conveying liquid is one of the important performance data for pump selection. It is directly related to the production capacity of the entire device. The working conditions of the fire pump: flow rate: 2～1400m3/h, Head: 5～130m, maximum working pressure of the system: ≤1.6MPa, working temperature: -15℃～+80℃.

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

Potential risks associated with diesel fire pumps include fuel spills, engine emissions, mechanical failures, and electrical hazards. These risks can be mitigated through proper risk assessment and mitigation strategies, such as implementing spill containment measures, ensuring proper ventilation in pump rooms, conducting regular equipment inspections and maintenance, and implementing safety protocols for fuel handling, storage, and disposal. Additionally, it’s essential to comply with relevant regulatory requirements and industry standards to minimize risks and ensure the safe operation of diesel fire pump systems.

An anechoic check valve, control valve and pressure gauge should be installed on the discharge pipe of the fire pump; a pressure gauge and pressure switch should also be installed on the total discharge pipe of the system; a buffer device should be added when installing the pressure gauge. A cork should be installed between the pressure gauge and the buffer device; the pressure gauge range should be 2 times to 2.5 times the working pressure of the system when there is no design requirement.
