Correct operation and rational use of fire vehicles and a variety of firefighting equipment and devices, is to give full play to the function of the fire truck, the rapid completion of the fire fighting and rescue mission is an important link. The following for the owners of friends to introduce the daily inspection and maintenance of fire engines:
1. Fire pump maintenance. Fire pump is the "heart" part of the fire truck. Fire pump maintenance directly affects the effect of fire fighting. Therefore, in the process of checking and maintaining the fire pump should be careful, found faults should be eliminated in a timely manner. General fire pump every 3 to 6 hours of work, the rotating parts to add a grease. To regularly test the fire pump maximum suction depth, lead time, maximum flow rate and other major technical parameters, such as a large difference with the normal performance should be checked and excluded. In the inspection and maintenance should pay attention to the following situations: such as the use of unclean water, should be pumps, tanks and pipeline cleaning; use of foam, to clean the pump in a timely manner, the foam proportion mixer and the connecting pipeline; put the net pumps, pipeline memory water; water ring pump priming tanks, scraper pump storage tanks, water tanks, foam tanks, the lack of storage capacity must be full of injection; check the water cannon or foam cannon ball valve base, cleaning activities parts of the TuLiHsu Grease should be lubricated; the oil in the priming pump and gear box should be checked in time, and if the oil is deteriorated (the oil becomes milky white) or missing, it should be replaced or supplemented in time.
2. Inspection and maintenance of the tank of the fire truck. As the tank of fire truck is in the state of full load of extinguishing agent for a long time, the soaking of extinguishing agent has certain corrosion on the tank, especially for some long-serving fire trucks, if not checked and maintained in time, the rust point will be enlarged and even rusted through the tank, and the rust residue will be washed into the pump when the fire truck is discharging the water, which will cause damage to the impeller and lead to the pump can not work normally. Especially the tank of the foam fire truck, because of the corrosive nature of the foam, if not regularly checked and maintained, not only the tank is easy to rust through, but also cause pipeline blockage, can not be normal delivery of foam, resulting in the failure of fire fighting and rescue operations. Therefore, should often organize the fire truck tank inspection, once found rust phenomenon, should take timely and effective measures to prevent the expansion of the rust point. Commonly used treatment method is to clean up the corroded parts, after drying, coated with epoxy resin paint or patch welding. Valves and pipelines of other parts related to the tank should also be checked and cleaned regularly, and problems should be dealt with accordingly.
3. Vehicle condition inspection and maintenance of good and bad directly affects the success or failure of fire fighting operations and the lives of combatants. The main contents of the vehicle condition check are: transmission system on the clutch, transmission, drive shaft, universal joints, reducer, differential, half shaft and other parts of the bolt is loose and damaged, lack of oil; brake system on the flexibility of the brake pedal, the work of the air compressor, whether the cylinder is intact, whether the brake valve is flexible, the wheel of the wear and tear of the brake pads; the steering wheel is working properly and lights, windshield wipers, Brake indicator and other important parts of the working condition. Check out the faults should be timely eliminated, such as the clutch does not disengage, should be timely overhaul and adjustment of the drive shaft, universal joints, reducer, differential, half-axis bolts loose, lack of oil in a timely manner to tighten and add lubricant.
4. Inspection and maintenance of the extractor and drive shaft. Whether the extractor and pump drive shaft are good or not is the key to whether the fire truck can absorb and discharge water. To regularly check whether the operation of the extractor is normal, there is no abnormal sound, gear and separation is smooth, there is no automatic out of gear phenomenon, if necessary, its inspection and maintenance. To check whether the water pump drive shaft has abnormal rattling sound, whether the fastening parts are loose or missing phenomenon, whether the cross section and bearing of the drive shaft need to be filled with grease, tighten the bolts and add grease if necessary.
