Explosion-proof forklift is used in special places. We first understand the characteristics of explosion-proof forklift itself and the characteristics of explosion-proof forklift operation area.

 

1, the first has been confirmed as the existence of combustible substances in the dangerous area of the operation, can strictly control the forklift itself of various ignition sources.

 

 

2. Secondly, while moderately controlling the ignition source of forklift truck, the gas concentration of the environment around the forklift truck can be detected by the gas detection system. When the concentration reaches a certain ratio of the lower limit of explosion, the forklift truck will start to alarm and finally stop automatically to achieve the purpose of safe operation. To ensure the safe operation of forklifts, ignition sources must be effectively controlled, including:

 

 

(1) It is necessary to eliminate the static electricity that may be generated in the operation of the vehicle and prevent the fire caused by collision between the outside of the vehicle, the rear of the vehicle and the cargo fork.

 

 

(2) make the diesel engine exhaust temperature up to 300-500℃ to the specified temperature group below (less than or equal to 135℃)

 

 

(3) Diesel engine intake due to inhalation of combustible gas or steam caused by overspeed out of control.

 

 

(4) When the forklift appears abnormal conditions such as water temperature, exhaust temperature, oil temperature and surface temperature, it should be able to automatically shut down the diesel engine in time.

 

 

(5) When the diesel engine burns normally or explodes accidentally, the flame passes through the intake system to produce backburn.

 

 

(6) diesel exhaust flame and fire consumption to the surrounding atmosphere.

 

 

To sum up, explosion-proof forklift to avoid leakage, avoid sparks and so on, so explosion-proof forklift must be processed by special.

 

 

The difference between explosion-proof forklift and ordinary forklift is mainly in the circuit, which has high requirements on the circuit, especially the motor, such as walking motor, steering motor, hydraulic lifting motor, which will spark when it turns.

 

 

There are special places where it can be dangerous, so special protection, isolation. Some use AC motors, because ac motors, at work when there is no spark, so it is relatively safe. A connection between wires. They have been specially treated and protected.
