The explosion-proof electric hoist is an explosion-proof lifting equipment designed and manufactured according to the latest explosion-proof standards in my country. Its explosion-proof form is "explosion-proof". The exposed explosion-proof parts of the hoist are made of special non-sparking materials, and the explosion-proof performance is safe and reliable. The product has passed the explosion-proof performance test of the Explosion-proof Electrical Product Quality Supervision and Inspection Center of the Ministry of Machinery Industry, and issued an explosion-proof certificate. Explosion-proof electric hoist has the advantages of light weight, small size and large lifting capacity.
Explosion-proof electric hoist is suitable for dangerous places where explosive gas mixtures exist in factories and dangerous places where there are explosive dust mixtures in factories. The main body can be hung on the I-beam track to run in a straight line or a curve, and it is also applied to lifting equipment such as explosion-proof single-beam cranes and explosion-proof suspension cranes. Explosion-proof electric hoists can be used in many coal mining enterprises and petroleum exploration projects, but this kind of mechanical equipment is different from ordinary machinery and requires more safety. Therefore, it is necessary to understand the explosion-proof level when purchasing, in order to choose the model suitable for your use.
The explosion-proof grades of explosion-proof electric hoists are mainly divided into three protection grades: ⅡA, ⅡB, and ⅡC
The explosion-proof grades of the explosion-proof electric hoist are mainly divided into three protection grades: ⅡA, ⅡB, and ⅡC. The temperature group is the place where the flammable gas of the T1-T4 group or the explosive gas mixture composed of steam and air. The explosion-proof electric hoist can be divided into B grade and C grade. Explosion-proof electric hoist is generally suitable for zone 1 and zone 2. The applicable temperature of the explosion-proof electric hoist is mainly from T1-T6, reaching the level of T6 is the highest temperature limit. For example, what DIICT4 represents is: d stands for flameproof type. II stands for Type II explosion-proof, that is, factory explosion-proof. C means it can be used in C-level explosion-proof areas, which means it can be used in the most dangerous areas. T4 represents the temperature group. At present, there are more DIICT4 grades for explosion-proof electric hoists.
Hazardous gas types EX IIBT4 ethane, propane, butane, heptane, ethylene, carbon monoxide, gasoline, acetone, styrene, toluene, benzene, methanol, ethanol, vinyl chloride, acetaldehyde, etc. EX IICT4 hydrogen, water gas, and gases other than EX IIBT4.
Among them, the explosion-proof electric hoist is mainly used in the following environments: petroleum, petrochemical, oil stations, oil depots, gas production, chemical, military, mining, electric power, electronics, railways and other environments. The specific need to analyze the surrounding temperature of the environment and the existence of dangerous gases, so Choose the right explosion-proof tool!
The equipment used in explosion-proof places is divided into: Class I, Class II, and Class III explosion-proof equipment. The use environment of Class I explosion-proof equipment is underground coal mines, and the use environment of Class II explosion-proof equipment is all other explosive gas environments except coal mines and underground. The applicable environment for Class III explosion-proof equipment is an explosive dust environment other than coal mines. Explosion-proof electric hoist explosion-proof grade is suitable for I type explosion-proof coal mines and non-excavation working face places and for II type explosion-proof. It has ⅡA, ⅡB, and ⅡC grades, and the temperature group is T1-T4. The explosiveness composed of flammable gas or steam and air Location of gas mixture. The working environment temperature is -25℃~40℃, suitable for indoor use; when used outdoors, protective devices are required. It should be noted that IIC is a higher explosion-proof level, but it does not mean that it is the best performance equipment. At present, the explosion-proof electric hoist does not support Class III explosion-proof environment!
In short, when you buy this product, you should look for a regular manufacturer and purchase the explosion-proof electric hoist of our factory with guaranteed quality, so that it is safer and more assured during operation.
