How to increase the adhesion traction of mining electric locomotive?
The maximum traction of mining electric locomotives is generally equal to the adhesive traction. It can be said that the adhesive traction determines the upper limit of the capacity of mining electric locomotives. Once the traction required by the mining electric locomotive is greater than the adhesive traction, the mining electric locomotive will begin to slip. In addition to illegal driving conditions such as overloading, as the use time of mining electric locomotives increases, its adhesive traction will also decrease, resulting in slippage. So what are the ways to increase the adhesive traction?
The definition of adhesive traction and friction of mining electric locomotive is similar, or the adhesive traction is the maximum static friction of mining electric locomotive, so when looking for ways to improve adhesive traction, you can follow the method of increasing friction, that is, adhesion Both coefficient and pressure.
First of all, the easiest thing to think of is to use more sanding devices. The sanding device is a device specially designed for mining electric locomotives to improve the adhesion coefficient during driving. The adhesion coefficient between the wheel and the track is improved through sand.
The second is to put wear-resistant rubber tires on the wheels. The purpose of doing this is to improve the adhesion coefficient between the mining electric locomotive wheels and the rails.
The second is to increase self-weight. When it comes to increasing the pressure, increasing the self-weight is the easiest way to think of it, but this increases the traction required by the mining electric locomotive itself while increasing the adhesive traction of the mining electric locomotive.
There is also a relatively complicated and more expensive way to increase the pressure-set up a magnetization device. The magnetization device is used to magnetize the wheel, because the magnetic adsorption principle makes the pressure between the wheel and the track also add magnetic force.
Finally, after experiments, there is a conclusion that at the same speed, low speed is conducive to ensuring the adhesion coefficient, that is to say, a larger wheel diameter can better ensure the adhesion coefficient.
The above are five ways to increase the adhesive traction of mining electric locomotives.
