Heavy foam fire truck efficient fire fighting and rescue equipment is suitable for petrochemical fire fighting

Description :

  Foam fire truck is a special vehicle specially used for fighting flammable liquid fires and general solid material fires. It mainly uses the vehicle mounted foam liquid tank and water tank to mix foam liquid and water in a certain proportion by using a proportioner to produce foam liquid mixture, which is sprayed by foam guns, foam monitors and other injection devices, covers the surface of combustibles, and quickly extinguishes the fire by isolating air and cooling. This model is particularly suitable for places with a large risk of flammable liquids, such as petrochemical enterprises, oil depots, gas stations, airports, ports, etc. It is an indispensable core firefighting and rescue equipment for fire departments and enterprise dedicated fire brigades, and can effectively deal with Class B fires and some Class A fires.

  The core specifications of foam fire truck include chassis type, water tank capacity, foam liquid tank capacity, foam mixing ratio, range and other parameters. Common chassis types include heavy-duty vehicles such as Howo, Dongfeng Tianlong, and Isuzu, which have strong load-bearing capacity and good driving stability. The water tank capacity is usually between 2 tons and 15 tons, and the foam liquid tank capacity is between 0.5 tons and 3 tons, depending on the size of the vehicle model. The mixing ratio of foam is usually 3% or 6%, which can be adjusted according to the fire demand. The roof is equipped with a remote control foam/water dual-use gun, with a horizontal range of more than 50 meters and a vertical range of more than 40 meters to ensure that the fire source can be accurately hit from a long distance. The body material is mostly high-quality stainless steel or carbon steel with anti-corrosion treatment, which complies with the national standard GB7956 "Fire Truck" and has passed the national mandatory product certification (CCC).

  When selecting, it is necessary to choose based on the actual size of the protected object, fire risk level, and road traffic conditions. It is recommended to use heavy foam fire engines in large petrochemical parks, which have large liquid carrying capacity and long range and are suitable for large-scale fire fighting; For small gas stations or communities, light or medium-sized foam fire engines can be used, which are flexible and convenient for narrow roads. Attention should be paid to distinguish between foam fire truck and water tank fire truck. The former has a foam mixing system, specializing in oil fires, and the latter is mainly used for general solid fires. If there are both solid and liquid fire risks in the protection area, it is recommended to select a combined foam fire truck with dual extinguishing functions of water and foam to improve the adaptability of emergency response.

  The daily maintenance of foam fire truck is very important, which directly affects the fire extinguishing efficiency. After each use, the foam pipeline, proportioner and injection device must be thoroughly washed with clean water to prevent foam liquid residue from corroding the pipeline or blocking the nozzle. Regularly check the quality of foam solution to avoid expiration or deterioration affecting the foaming ratio and stability. Check the operation of the water pump, whether the power take-off is smoothly connected, and whether the valve switch is flexible every month. In winter, it is necessary to drain the accumulated water in the pump and pipeline to prevent freezing and cracking. Common failures include foam imbalance, insufficient range, etc., which are often caused by mixer blockage or insufficient pressure. It is necessary to clean the filter screen regularly and check the pump pressure. Keep the appearance of the vehicle clean, ensure that warning lights and alarms are working properly, and be in a state of readiness at all times.
