Explosion-proof flashlight features and precautions for use

Posted on

Explosion-proof flashlights are suitable for mobile lighting in various flammable and explosive places, and for mobile lighting inside and outside the ship, metallurgy, railway, electric power and various industrial and mining enterprises. Explosion-proof flashlights are strictly in accordance with IS9001:2000 international quality management system standards for quality control, to ensure that explosion-proof flashlights are higher than national standards, fully meet the design requirements, explosion-proof flashlights for 3 years warranty.
The explosion-proof flashlight is specially designed to meet the needs of mobile lighting in the heavy industry of ships and metallurgy. The JW7210A developed is an upgraded version of JW7210. The impact resistance is solved and it can work safely in inflammable and explosive places. Its high-energy non-memory battery has large capacity, long life and low self-discharge rate. It adopts high-power, high-brightness white LED light source. The illumination distance of the lamp can reach more than 100 meters, the visible distance is more than 5000 meters, and the continuous use is 12 hours. Consistently, it can work normally under 50 meters of water; imported high hardness alloy casing can withstand strong collision and impact.
In the explosion-proof flashlight, the performance of the explosion-proof lithium battery is related to the lighting use time of the explosion-proof flashlight, so a good explosion-proof lithium battery is essential for a high-end explosion-proof flashlight. The positive electrode material of a lithium ion battery usually consists of an active compound of lithium, and the negative electrode is a carbon of a special molecular structure. The main component of the common positive electrode material is LiCoO2. When charging, the potential applied to the two poles of the battery forces the compound of the positive electrode to release lithium ions, and is embedded in the carbon in which the negative electrode molecules are arranged in a sheet structure. At the time of discharge, lithium ions are precipitated from the carbon of the sheet structure and recombined with the compound of the positive electrode. The movement of lithium ions produces a current.
Lithium-ion batteries will still have a reduced capacity after repeated charge and discharge, which is complicated and diverse. Mainly the change of the positive and negative materials themselves. From the molecular point of view, the hole structure containing lithium ions on the positive and negative electrodes will gradually collapse and block; from the chemical point of view, the positive and negative materials are reactively passivated, and the side reaction is stable. Other compounds. Physically, the positive electrode material gradually peels off, and finally, the number of lithium ions in the battery that can freely move during charge and discharge is finally reduced. Overcharging and over-discharging will cause permanent damage to the positive and negative electrodes of lithium-ion batteries. From a molecular perspective, it can be intuitively understood that excessive discharge will cause the anode carbon to release lithium ions excessively, causing the sheet structure to collapse. Overcharging will hardly plug too much lithium into the negative carbon structure, and some of the lithium ions will no longer be released. This is why lithium-ion batteries are usually equipped with a charge and discharge control circuit.

Electric​ Heater

1. The inner core of the electric heat pipe is made of high-quality stainless steel or other materials, with a coat of PTFE, which is highly corrosion-resistant and suitable for heating various corrosive liquids.

2. Low surface power design (1.5kw /CM) to ensure the service life of the product.

3. The installation position of the electric heater should be paid attention to prevent the solid in the solution from depositing on the surface of the electric heater, or the liquid is too thick and the liquid level is too low, which will cause the teflon tube (PTFE) to be burnt due to the poor surface heat.

4. The shape is divided into vertical type and bottom heating "L" and "Z" type.
