Explosion-proof electric forklift

Electric forklift can be divided into many kinds according to its function, among them VOLOX Xiao Bian is to introduce everybody today is VOLOX explosion-proof electric forklift. What is it called explosion-proof electric forklift? How should the explosion-proof function of an electric forklift qualify as qualified?

We know that explosive mixtures are common in coal, petroleum, chemical, textile, and grain processing industries. Due to the requirements of safe production, explosion-proof forklift trucks are widely used in such industries as production, processing, storage and transportation. The design measures for explosion-proof lift trucks are mainly started with the "three elements of explosion."

One of the three elements of the explosion: explosive or flammable substances must be present;

The second element of the explosion: The flammable substance, mainly oxygen in the air;

The third element of the explosion is the existence of an ignition source that provides the energy necessary to ignite the mixture.

Explosion-proof electric forklifts need to adopt the following basic protection measures according to the “three elements of explosion”:

1. Control the surface temperature of the vehicle so that it is not higher than the temperature set value specified by the explosion-proof forklift.

2. Forklift electric motors, batteries, switches and meters and other electrical components to take protective measures to eliminate or control arc and spark.

3, tires, forks, body collision parts to take anti-collision sparks measures.

4, using automatic control system for over-temperature, speed and leakage protection.

5. Effectively monitor the concentration of explosive mixtures in the work area.

Explosion-proof electric forklift technical characteristics:

1. The AC control system has low power constant torque control and high speed constant power control, so it has good power performance, energy recovery function, ramp anti-slipping function, deceleration function and so on.

2. The AC motor does not use contacts and carbon brushes in its structure, so there is no need to clean and replace the carbon brush with maintenance-free, which makes the explosion-proof safety improved.

3. Through the control of the two temperature sensing and control systems in the explosion-proof AC motor, the explosion-proof forklift has two control operating conditions of heat rise and heat drop, which not only improves the temperature rise control ability of the explosion-proof forklift, but also to a large extent. Ensure the normal operation of the whole machine.

4, the use of hydraulic wet brake brake form, to avoid the brake spark and high temperature, increased the explosion-proof performance of the machine.
