What kind of fire extinguisher should the motor catch on
Use dry powder fire extinguishers. Dry powder is a dry, easy-to-flow fine solid powder composed of a base material capable of extinguishing fire, a moisture-proof agent, a flow accelerator, a caking preventive agent and other additives. It is mainly used to fight the initial fires of flammable liquids, combustible gases and electrical equipment such as petroleum and organic solvents.
Common dry powder fire extinguishing agents are mainly composed of active fire extinguishing components, hydrophobic components, and inert fillers. The hydrophobic components are mainly silicone oil and hydrophobic white carbon black. There are many types of inert fillers. Silicone oil polymerization and improved compatibility with foam fire extinguishing agents. This type of ordinary dry powder fire extinguishing agent has been widely used at home and abroad.
The end-of-life of dry powder fire extinguishers The fire extinguishers must be scrapped when they reach the following years from the factory date:
Portable dry powder fire extinguisher (gas cylinder type)-8 years.
Portable dry powder fire extinguisher-10 years.
Cart-type dry powder fire extinguisher (gas cylinder type)-10 years.
Cart storage pressure dry powder fire extinguisher-12 years.
The most commonly used opening method for dry powder fire extinguishers is the pressure handle method. After putting the fire extinguisher into the proper position from the fire source, turn it upside down several times to loosen the dry powder in the cylinder, and then point the nozzle at the most violent burning place, pull out the safety pin, press down the handle, and the fire extinguishing agent will be sprayed out Extinguishing.
When the dry powder fire extinguisher is turned on, hold the middle part with the left hand, aim the nozzle at the root of the flame, pull out the insurance card with the right hand, turn the opening knob, and open the gas cylinder. After a delay of 14 seconds, the dry powder will spray out to extinguish the fire.

1. When the motor catches fire, first try to cut off the power supply, and then use a dry powder fire extinguisher to extinguish the fire.
2. The ordinary dry powder fire extinguishing agent is mainly composed of active fire extinguishing components, hydrophobic components, and inert fillers. The hydrophobic components are mainly silicone oil and hydrophobic white carbon black. There are many types of inert fillers, which mainly prevent vibration and agglomeration, and improve the performance of dry powder. It catalyzes the polymerization of dry powder silicone oil and improves the compatibility with foam fire extinguishing agents. This type of ordinary dry powder fire extinguishing agent has been widely used at home and abroad.
A carbon dioxide fire extinguisher should be used.
First of all, water will never work. Dry powder fire extinguishers mainly use physical reactions and chemical reactions to extinguish the fire. Alkaline substances in the dry powder have a certain corrosive effect on the coiled wire on the motor coil. The use of carbon dioxide fire extinguishers is physically not helpful. High-concentration carbon dioxide can act as a protective film to prevent oxygen from entering to achieve fire extinguishing effect. As for the above comparison, it is better to use carbon dioxide fire extinguisher
