Pay Attention To The Discharge Of Underground Mining Electric Locomotive!

Electric locomotive is often used by supplying electric energy through battery, which has been widely used in gas mines. The discharge process of battery electric locomotive is the premise of ensuring the long-term use of the underground mining locomotive, but we also need to pay attention to this process, so what should be paid attention to in the discharge process of electric locomotive?

Reduced battery capacity. In addition to aging, over discharge, reduction of active substances, falling off of plates, quality problems and other reasons, the density of electrolyte is too low, which is also the reason for the reduction of battery capacity. In narrow gauge locomotive daily maintenance, the specific gravity of electrolyte is often measured with a hydrometer. When the specific gravity is lower than 1.28, the multi-functional standard liquid is used to adjust to the standard value, so as to ensure that the battery is charged with enough electricity and the battery is stored Capacity of the pool.

Sparks are generated on the battery surface. In the process of battery charging, sparks are generated between the narrow gauge locomotive battery surface and the plastic partition or steel plate, which is a discharge phenomenon.

The reason is the overflow of electrolyte, such as the rupture of battery tank and battery cover, the dripping of electrolyte during the pouring, the overfilling of the battery, the shortage or tightness of the cock when the narrow gauge locomotive is running, etc. the primary battery is formed between the two points, resulting in the potential difference, and the electric spark is generated through the discharge circuit. It is necessary to wash the electrolyte with clean water and keep the battery surface clean and dry.

The battery is damaged. If the battery electric locomotive is damaged by a single battery, it is mostly caused by the short circuit between the positive and negative plates of the battery itself. If there are regular multiple batteries or even the whole power box is damaged, it is mostly caused by external reasons

For example, the external load is too large, long-term overload traction, or even short circuit, when the insulation of the positive or negative lead cable is damaged, it is short circuited with the pole of unequal potential point, and some batteries are short circuited, etc., which will cause the damage of the narrow gauge locomotive battery, so it must be paid full attention to. When the locomotive is running, it is necessary to avoid overload traction, carefully check the insulation of the lead cable of the electrode and add a set of insulation pipe to prevent the battery from being damaged Large current discharge, avoid damaging the battery due to excessive current.
