Chemical explosions are pided into solid, liquid, and gas explosions, depending on the state of the substance. Many industries and units such as petroleum, chemical, pharmaceutical, paint, paint and coal are producing, concentrating, liquefying and storing flammable gases, or producing, filling, releasing and storing flammable liquids and treating them with liquids, When cleaning objects, possible combustible gases or dust are mixed with air to form explosive mixtures that make these areas inaccessible to normal vehicles.

 

Explosion-proof forklifts are designed and manufactured specifically for locations where explosive gases or dust may be generated, primarily to prevent the vehicle from exploding when operating in an explosive atmosphere.

 

Below for everyone to analyze some explosion-proof forklift knowledge:

 

一, flammable gas explosion conditions

 

1, internal conditions: flammable gas concentration within a certain range, the lowest concentration to the highest concentration between the explosion.

 

2, external conditions: ignition flash or open fire, ambient temperature above the ignition point, there is a certain amount of energy radiation, detonation may occur. Specific to the vehicle is reflected as: spark; mechanical collision spark; motor, electric control, brakes, pumps and valves and other easy-heating temperature, may cause an explosion.
 

二, the explosive gas environment, according to the degree of danger can be pided into three regions

 

Zone 0: Explosive gas atmospheres occur continuously or for a long time. (Mobile industrial vehicles are not allowed to enter)

 

Zone 1: A place where an explosive atmosphere may appear during normal operation.

 

Zone 2: In normal operation, explosive gas atmospheres are less likely to occur, and if they occur occasionally, and only for short periods of time.


Currently the highest level of explosion-proof forklifts at home and abroad are only in Zone 1 and Zone 2 safe operation.

 

三, explosion-proof forklifts taken by the explosion-proof way

 

Intrinsically Safe: Restricted from the energy of the circuit, sparks, arcs and temperatures are not sufficient to ignite explosive gases, either in normal or short-circuit fault conditions.

 

2, explosion-proof forklift structure Explosion-proof type: the use of structural isolation measures to isolate the electrical and the surrounding environment. Commonly used are: Flameproof, increased safety, pressure type, oil-filled type, sand filling type, sealing type and other forms.

 

At present, the explosion-proof type of electric explosion-proof forklift truck is mainly explosion-proof type. The principle of the explosion-proof type electric explosion-proof forklift is that in normal operation, the components capable of generating spark arcing in electrical equipment are placed in a flameproof enclosure which can withstand the internal pressure without damage Can ensure the internal flame gas spread through the gap, reducing energy, not enough to detonate the gas outside the shell.
