Proper operation and rational use of fire-fighting vehicles and various special fire-fighting equipment and equipment are important parts in giving full play to the functions of fire engines, rapid completion of firefighting fighting and rescue missions. The following describes the daily inspection and maintenance of fire engines for car owners:
1. Fire pump maintenance. The fire pump is the "heart" part of the fire engine. Fire pump maintenance directly affects the effectiveness of fire fighting operations. Therefore, in the inspection and maintenance of the fire pump process should be carefully and found that the fault should be promptly removed. Generally, the fire pump must be filled with grease once every 3 to 6 hours. Regularly test the main technical parameters such as the maximum water absorption depth, water diversion time, and maximum flow rate of the fire pump. If there is a large difference from the normal performance, check and eliminate it. During inspection and maintenance, attention should be paid to the following: If unclean sources of water are used, the pumps, water tanks, and pipelines should be cleaned; after the foam is used, the pumps, foam proportioners, and connecting lines must be cleaned in time; , pipeline memory water; water ring pump cistern, scraper pump storage tank, water tanks, foam tank reserves must be filled; check the water gun or foam gun ball valve base, clean the moving part of the paint and grease to lubricate; The oil in the pump and gearbox is checked in a timely manner. If the oil deteriorates (the oil turns milky) or is missing, it should be replaced or supplemented in time.
2. Inspection and maintenance of fire tanks. Due to the long-term state of fire extinguishers contained in fire tanks, the soaking of fire extinguishing agents will corrode the tanks, especially for some long-serving fire engines. If the fire tanks cannot be inspected and maintained in time, the rust spots will expand and even cause rust to pass. In the tank, its detached rust residue will be flushed into the pump when the fire truck is out of the water, and damage to the impeller will cause the pump not to work properly. In particular, foam tanks for foam fire trucks have large corrosiveness due to foam. If they are not regularly inspected and maintained, not only will the tanks be easily rusted, but also the pipes will be blocked and the foams will not be transported normally, resulting in the failure of fire fighting and rescue operations. Therefore, the fire tank should be regularly inspected. Once rust is found, effective measures should be taken to prevent the rust from expanding. The commonly used treatment method is to clean the rusted part, dry it, coat it with epoxy paint or repair it. All other parts of the valve and piping related to the holding tank should also be checked and cleaned periodically, and the problems should be found and handled accordingly.
3. The quality of the vehicle condition check and maintenance directly affects the success or failure of the fire fighting operation and the life safety of the combatants. The main contents of the condition check include: if the bolts on the transmission system such as the clutch, transmission, transmission shaft, universal joint, reducer, differential, and axle, etc. are loose and damaged, the oil is lacking; the brake is applied to the brake pedal. Flexibility, working conditions of air compressors, whether the air reservoir is in good condition, brake valves are flexible, and the brake pads of the wheels are worn; the operation of the steering wheel is normal and the working status of important components such as lights, wipers, brake lights, etc. Check out the faults should be promptly removed, such as the clutch is not separated, should promptly repair and adjust the drive shaft, universal joints, reducer, differential, loose shaft bolts, oil shortage, timely tightening and lubrication.
4. Inspection and maintenance of power take-off and transmission shaft. Whether the power take-off and the water pump drive shaft are easy to use is the key to the ability of the fire truck to absorb water and water. It is necessary to periodically check whether the power take-off is operating properly, whether there is any abnormal noise, whether the gears are detached and separated smoothly, and whether there is an automatic gear shift phenomenon. If necessary, check and maintain the power take-off. Check whether there is any abnormal noise in the pump drive shaft, whether the fastening parts are loose or defective, whether the ten-axle of the drive shaft and the bearing need to be filled with grease, if necessary, tighten the bolts and add grease.
The Pressure Vessel Series is a collection of vessels designed to contain fluids or gases at high pressure. These vessels are used in a variety of industries, including chemical processing, oil and gas, and power generation. The vessels are typically made of steel or other high-strength materials, and are designed to withstand the extreme pressures and temperatures that they are exposed to.
One of the key features of the Pressure Vessel Series is their ability to safely contain high-pressure fluids and gases. This is achieved through a combination of design features, such as thick-walled construction, reinforced seams, and pressure relief valves. These features help to ensure that the vessel can withstand the high pressures and temperatures that are present inside, while also providing a safety mechanism in case of a failure.
Another important aspect of the Pressure Vessel Series is their versatility. These vessels can be used for a wide range of applications, including storing and transporting gases and liquids, as well as processing raw materials into finished products. They can also be customized to meet specific industry needs, with options for different sizes, shapes, and materials.
In addition to their functional benefits, the Pressure Vessel Series also offers economic advantages. By allowing for the safe and efficient storage and transport of high-pressure fluids and gases, these vessels help to reduce waste and increase productivity. They also provide a cost-effective solution for industries that require high-pressure containment, as they are often less expensive than alternative solutions.
Overall, the Pressure Vessel Series is an essential component of many industrial processes. From chemical processing to power generation, these vessels provide a safe, reliable, and cost-effective solution for high-pressure containment. With their versatility and durability, they are sure to remain an important part of industrial operations for years to come.
