No matter what kind of machine, it needs maintenance, maintenance is better than repair
The correct operation and rational use of fire fighting vehicles and various special fire fighting equipment and equipment is an important part of giving full play to the functions of fire fighting vehicles and quickly completing fire fighting and rescue operations. Note the following:
1. Inspection and maintenance of equipment boxes. The equipment box is mainly used to store special equipment for fire fighting and emergency rescue. It is the most commonly used and most easily overlooked place. The quality of the equipment box will affect the service life of the equipment. First of all, the place where the friction equipment is to be isolated or protected with rubber or other soft substances. Secondly, it is necessary to frequently check whether there is water in the box, whether the fixed bracket is stable, whether the curtain door is flexible in opening and closing, whether there is deformation or damage, whether there is a lack of oil in the lubricating oil groove on the side of the door, etc., and add grease if necessary. Protect.
2. Inspection and maintenance of fire truck containers. Since the container of the fire truck is full of fire extinguishing agent for a long time, the bubble of the fire extinguishing agent will corrode the container to a certain extent. Especially for some fire trucks with long service life, if they cannot be inspected and maintained in time, the rust spots will expand or even become The rust slag will be flushed into the water pump when the fire truck comes out of the water, and the impeller will be damaged and the water pump will not work properly. Especially the container of the foam fire truck, due to the high corrosiveness of the foam, if the container of the fire truck is checked irregularly, once rust is found, effective measures should be taken in time to prevent the expansion of the rust point. The common treatment method is to clean the corroded part, and then apply epoxy paint or repair welding after drying. The valves and pipelines of other parts related to the container should also be regularly inspected and cleaned, and problems should be dealt with accordingly.
3. Inspection and maintenance of electrical appliances and instruments. Appropriate fuses should be used for vehicle electrical circuits to avoid damage to the original electrical components. The warning lights and siren systems should be checked regularly to see if they can work normally. If there is any abnormality, the fault should be eliminated in time. The contents of the electrical inspection of the water system and lighting system include: equipment box lights, pump room lights, solenoid valves, liquid level indicators and digital tachometers, as well as the working conditions of various meters and switches.
4. Inspection and maintenance of fire pump. The fire pump is the "heart" part of a fire truck. The maintenance of fire pump directly affects the effect of fire fighting. Therefore, in the process of inspection and maintenance of the fire pump, you should be careful and careful, and the fault should be eliminated in time. Generally, every 3 to 6 hours of operation of the fire pump, each rotating part should be filled with grease once. The main technical parameters such as the maximum water absorption depth, water diversion time, and maximum flow of the fire pump should be tested regularly. If there is a large difference with the normal performance, it should be checked and eliminated. During inspection and maintenance, pay attention to the following conditions: if unclean water source is used, the water pump, water tank and pipeline should be cleaned; after using foam, the water pump, foam proportioning mixer and each connecting pipeline should be cleaned in time; , water in the pipeline; water ring pump water tank, scraper pump oil storage tank, water tank, foam tank must be filled with insufficient reserves; check the water cannon or foam cannon ball valve base, clean the moving parts and add lubricating oil appropriately to lubricate; The oil in the water pump and gearbox should be checked in time. If the oil deteriorates (the oil becomes milky white) or is missing, it should be replaced or supplemented in time.
5, vehicle condition inspection and maintenance. The condition of the vehicle directly affects the success or failure of the fire fighting operation and the life safety of the fighters. The main contents of the vehicle condition inspection are: whether the bolts on the clutch, transmission, drive shaft, universal joint, reducer, differential, half shaft and other components are loose and damaged, and lack of oil; Flexibility, the working condition of the air compressor, whether the gas storage is in good condition, whether the brake valve is flexible, the wear condition of the brake pads of the wheels; whether the steering gear is working normally, and the working conditions of important components such as lights, wipers, and brake indicators . The detected faults should be eliminated in time. If the clutch does not disengage, the drive shaft, universal joint, reducer, differential, and half shaft bolts should be repaired and adjusted in time. If there is a lack of oil, it should be tightened and lubricated in time
