If the fire pump is used correctly, and has been seriously maintained and maintained, generally its use time is relatively long, but many manufacturers still want to look for tips to extend the service life of the pump, the following teach you a few tricks to extend the service life of the pump:
1. Fire Pump should be used in a place with good ventilation. Portable Pump is conducive to heat dissipation and reduce motor temperature. Before starting, carefully check the amount of water stored in the pump, otherwise it will not only affect its self-priming, but also easy to burn the shaft seal parts.
2. When the pump fails, it can not be disassembled by itself.
3. Before starting, check whether the fire Pump can start normally and whether the Portable Pump has no jam; Whether the position of impeller is normal; Cable and cable plug whether broken, scraped and broken phenomenon.
4, non-use period stored in the non-use period, immediately put the fire pump away from the water source, and drain the water in the pump, especially in cold weather. Then leave it in a dry place.
The service life of the fire pump is related to the user’s usual usage habits. The service time of the pump is longer, and its replacement frequency is reduced, which can save a lot of costs for the manufacturer. The above methods help the user to use the pump.
Correct maintenance of diesel engine fire pump, especially preventive maintenance, is relatively easy and economical maintenance, to check the fuel volume of the fuel tank, as needed to observe the storage capacity of the fuel tank. Therefore, the key is to extend the service life and reduce the cost. To perform routine maintenance, perform the following steps.
1. Check whether the water in the diesel engine fire pump tank is enough. If the water in the tank is found to be insufficient, it should be replenished promptly. The water added should be clean fresh water, such as tap water or clean river water. If groundwater is used directly, it is easy for Portable pumps to scale up in the tank, thus affecting the cooling effect and causing damage. Therefore, groundwater can only be used after softening. In THE NORTH (AMBIENT TEMPERATURE BELOW ZERO), ANTIFREEZE MUST BE CONFIGURED AT THE APPROPRIATE freezing point according to the low temperature of the area.
2. Check whether there is enough grease at the injection point of the diesel engine fire pump: remove the injection nozzle on the diesel engine circulating water pump and observe whether there is enough grease. Otherwise, inject enough grease into the oil gun.
3. Check the connection plate of injection pump transmission of diesel engine fire pump: check whether the connection screw is loose. If loose, recalibrate the injection advance Angle and tighten the connecting screw.
4. Check the oil surface in the oil pan of the diesel engine fire pump: observe whether the oil surface reaches the mark on the dipstick. When the oil surface is not enough, the oil surface should be added to the specified amount, but cannot exceed the upper limit of the ruler line.
5. Check the oil level of the fuel injection pump governor of the diesel fire pump: if the specified mark is not reached, add enough oil (some fuel pump governor does not have a ruler, this step can be omitted).
6. Clean the appearance of the diesel engine and its accessories of the diesel engine fire pump: wipe the fuselage, turbocharger, cylinder head housing, air cleaner and other surfaces, such as oil stains, water and dust, with dry cloth or diesel immersion cloth; Use compressed air to clean or blow dust off surfaces such as rechargeable generators, radiators and fans.
The above is the correct maintenance method of diesel engine fire pump, often used will keep the lubrication of diesel engine parts, prevent the oxidation of electrical contacts, but also help diesel engine start safely and reliably. Therefore, the diesel pump should be started at least once a week to check whether the system is normal and record the running parameters through the computer.
