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.

Diesel engine fire pump is also called “engineering diesel engine fire pump group”. Diesel engine fire pump group has the characteristics of good starting characteristics, strong overload capacity, compact and reasonable structure, convenient maintenance, simple and reliable use and so on. The unit is equipped with protection functions such as overspeed, low oil pressure, failure to start three times, high water temperature, low oil level, and low battery voltage. It can fully meet the fire water supply in various occasions such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas stations, textiles and other industrial and mining enterprises.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little impact on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the machine body is between 85 and 95 °C. If the water temperature is too high, you can increase the opening of the ball valve, increase the heat dissipation capacity of the heat exchanger, and reduce the temperature of the engine cooling water.
