It is often installed on fire trucks, fixed fire extinguishing systems or other fire-fighting facilities for transportation Special pumps for liquid extinguishing agents such as water or foam solutions. Fire pumps are widely used in environmental protection, water treatment, fire protection and other departments.

With the continuous progress of the times, the application of diesel engine fire pumps is becoming more and more extensive. Diesel engine fire pump is a common necessary facility. Only when the fire signal comes, and the electric water pump fails or the power supply is cut off, the diesel engine fire pump will automatically start. The diesel engine fire pump is installed together with the electrical instrument, with complete functions, compact structure, automatic fault alarm, accepting the starting signal, and can automatically complete the starting procedure and run at full load quickly. When the diesel engine fire pump is insufficient in fuel, low battery voltage, and high lubricating oil temperature , enough to ensure that the diesel engine fire pump starts in a low temperature environment, the entire system of the diesel engine fire pump is safe, reliable, and easy to use.

Yes, there are various types of nozzles available for firefighting pumps, each designed for specific purposes. For example, fog nozzles disperse water into a fine mist, which is useful for cooling and controlling fire, while solid stream nozzles deliver a concentrated stream of water for long-range firefighting. Choosing the appropriate nozzle can significantly impact the effectiveness of firefighting efforts.

Fire pumps can function with electric motors or diesel engines, and if local building codes require electricity independent of the local grid, pumps using electric motors can use the installation of an emergency generator when connected through a transfer switch listed.

The so-called self-priming pump does not require irrigation before starting, and after a short period of operation, the water can be sucked up by the function of the pump itself and put into normal operation.

Self-priming pumps are divided into the following categories according to their working principles:

(1) Gas-liquid mixing type (including internal mixing type and external mixing type);

(2) Water ring wheel type;

(3) Jet type (including liquid jet and

Fire pumps have a wide range of uses. In addition to providing water for fire-fighting piping systems, they can also be used for industrial water delivery.

There are numerous ways to maintain fire pumps and water pumps. The following styles are more effective. You can use them for reference
System 1 The installation of the pump set should be accurate and dependable, and there should be no egregious vibration duringoperation.However, or the bearing is hot to the touch( the temperature is advanced than 60 °C) and the water seepage in the seal of the pump shaft is further than 60 drops per nanosecond, the cause must be set up out and the fault should be excluded in time, If the pump makes abnormal noise when pumping water.
the
system 2 Screws that are squinched daily, similar as packing gland screws, irrigation entrapments,etc., should be disassembled with a suitable wrench and a reasonable necklace. You can put some slicking oil painting on it or wipe it regularly with an oil painting cloth to help rust; if the water drain screw isn’t used constantly, it’s easy to rust, so after buying a new water pump, you should first wind the water drain draw, and apply some machine oil painting and white lead oil painting on the screw thread, Change the new oil painting two or three times a time in the future.
the
System 3 If the pump is waxed with machine oil painting, the slicking oil painting should be replaced once a month; if it’s waxed with adulation, it should be replaced every six months. It should be noted that the water pump uses calcium- grounded grease, and the motor uses sodium- grounded grease, and they shouldn’t be used inaptly. Because sodium- grounded grease is hydrophilic, it’ll emulsify into froth and dissipate when it encounters water on the pump, while calcium- grounded grease is hysterical of high temperature, so it’s easy to melt when the temperature rises when used on a motor.

system 4 Don’t pump water with too important beach, so as to avoid unseasonable wear and tear of the impeller, mouth ring and shaft, and try to help water deficit operation. Running without water will damage the water seal, and the water pump is prone to water leakage or indeed no water.
System 5 After the irrigation and drainage season is over, the water pump should be precisely gutted and auditedimmediately.However, they should be repaired or replaced in time, and the corridor that should be waxed should be filled with suitable oil painting; Stylish stored in a dry place, If any damaged or misshaped corridor are set up to be unworkable.
