Analyze the cause of fire of excavator and prevent fire



I. Analysis of the cause of fire in excavator maintenance and repair

1, years of disrepair

Classic cars are the most susceptible to fire.Due to the aging of the hardware wires, it is easy to cause short circuits, loose parts, coupled with several hands falling in the middle, whether there has been an accident in the middle, and what parts are used for splicing and assembly are long unclear. It's heavy, and it can cause danger if you touch Mars.

2.Hydraulic pipe burst during operation caused hydraulic oil to be sprayed onto the exhaust pipe and caused a fire

The fundamental reason for the burst of the hydraulic pipe is that the action of the actuator is suddenly obstructed. Under the condition of sudden pressure increase, the oil return system of the excavator cannot return to the oil in time to cause a sudden rise in the pressure of the pipeline, which causes the pipe to burst.

3. The circuit is short-circuited (the current is directly connected to the two poles of the power supply without using electrical appliances), and the oil circuit catches fire.

Always inspect the circuit inside the car, use fuses in accordance with regulations, and regularly maintain (replace) damaged circuits, so as to drown the danger in the bud!

Second, prevent excavation (excavate) machine fire

1.The car body is kept clean and free of oil and dirt, which prevents running leakage

Sometimes the chassis bottom plate is too dirty, and there is too much oily soil or oily rubbish mixture. Once there is a short circuit (the current is directly connected to the two poles of the power supply without using electrical appliances), it will definitely ignite. It usually ignites. It is also possible to flush with water. Corrosion is okay. The key to safety is first. Excavator maintenance Due to the complicated structure of the excavator, high technical content, large workload, and harsh construction environment, failures are inevitable. The company has rich experience in various symptoms of excavators and strong technical strength.

2, operating control hands to develop good personal habits

It is a very dangerous action to operate the control hand to smoke in the cab. In addition, things are scattered in the cab, tools are piled up, and battery fluid flows out. I do n’t know. This is a very big fire hazard. There are many The flames of the excavator first came out of the cab.

3. Try not to use water for fire extinguishing, especially the fire in the circuit oil circuit.

It is best not to use water to extinguish fires on circuits or oil fires. Sand may be better. Of course, it is best if you have professional fire extinguishing equipment. Excavator maintenance professionally engaged in excavator maintenance, excavator repair, excavator repair factory has many years of maintenance experience, on 1000 maintenance cases, domestic cutting-edge excavator maintenance equipment, proficient in excavator maintenance.

4, must be equipped with a fire extinguisher

Regarding the principle of equipping fire extinguishers, there are still a lot of excavator owners who don't pay attention to them. In fact, the excavator is relatively easy to find at the beginning of the fire. At this time, if a fire extinguisher is used, it is possible to avoid a fire. Avoid huge losses for car owners. A bottle of fire extinguisher, but a hundred dollars, and an excavator is a million dollars. I would advise owners who have not equipped themselves with a fire extinguisher, and hurriedly correct it. Choose a slightly larger fire extinguisher. Some, of course, the fire extinguisher should also be inspected frequently if it is out of date and the pressure is at the standard value. Do not wait until the emergency to find that the fire extinguisher is unusable. Excavator repair is a well-known service company for domestic excavator repair, excavator repair, and excavator repair. It has state-of-the-art maintenance testing equipment and is mainly engaged in various excavator repair businesses.
