Description: Explosion-proof hoist is divided into explosion-proof electric hoist and explosion-proof chain hoist. Its explosion-proof characteristics are mainly determined by its material. Because its field of use is special, it is mainly used in some special places, such as containing flammable gases, The place where explosive gas is mixed with steam and air, so when purchasing explosion-proof hoist, in addition to the special requirements of the material, it is also required in some technical aspects, and can be divided into different protection levels.
Explosion-proof hoist is divided into explosion-proof electric hoist and explosion-proof chain hoist. Its explosion-proof characteristics are mainly determined by its material. Because its field of use is special, it is mainly used in some special places, such as containing flammable gases, steam and The place where explosive gas is mixed with air, so when purchasing explosion-proof hoist, in addition to the special requirements of material, it also has certain technical requirements, and can be divided into different protection levels.
体混合物的场所。 Explosion-proof electric hoist is mainly divided into three protection levels of ⅡA, ⅡB, and ⅡC, and the temperature group is T1-T4 group of flammable gas or an explosive gas mixture composed of steam and air . Explosion-proof electric hoist can be divided into B grade and C grade. Explosion-proof electric hoist is generally applicable in zone 1 and zone 2. T1-T6，达到T6这个级别是最高温度限制。 The applicable temperature of explosion-proof electric hoist is mainly from T1-T6, reaching the T6 level is the maximum temperature limit. For example, DIICT4 represents: d stands for flameproof type. II stands for Type II explosion-proof, namely factory explosion-proof. 表可用于C级防爆区域,也就是可用于最危险的区域。 C stands for C-grade explosion-proof area, that is, it can be used in the most dangerous area. T4 stands for temperature group. At present, there are many DIICT4 grades for explosion-proof electric hoists.
Explosion-proof electric hoist can be selected according to different places. The explosion-proof hoist produced by our company can be divided into metallurgical electric hoist, BCD type explosion-proof electric hoist, explosion-proof chain electric hoist, explosion-proof chain hoist, and other types. Explosion-proof lifting equipment. The following introduces the common sense of application of explosion-proof hoist:
动葫芦跑车在轨道上的运行速度不得大于25m/min。 1. In order to prevent sparks due to mechanical friction or collision, the exposed parts of explosion-proof electric hoists should adopt speed limiting technical measures. The wire speed of the wire rope and the reel and the speed of the electric hoist sports car on the track must not be greater than 25m / min .
的摩擦。 2. There should be no broken wires on the surface of the explosion-proof hoist wire rope, and the wire rope should have reliable lubrication measures to reduce the friction between the wire rope and the drum, rope guide and pulley parts .
3. The running track joint of the explosion-proof electric hoist should be smooth and flat, and the sports car should have no impact or obstruction during operation.
4. Ensure that the brakes of the explosion-proof hoist sports car are stable and the wheels are prevented from slipping.
5. If there are more than two explosion-proof hoists running on the track at the same time, an anti-collision buffer device should be provided. 材料，其表面电阻不得大于10。 At the same time, there are strict requirements for the material of the buffer device, which should be non-metallic materials, and its surface resistance must not be greater than 10.
告标识。 6. When there are many metal obstacles in the working environment of explosion-proof electric hoist, in order to prevent the hoist hook from colliding with metal obstacles, warning signs should be marked on the side plate of the hook pulley .
意说明说中提到的注意事项。 Because of the special characteristics of explosion-proof electric hoist, when purchasing explosion-proof electric hoist, be sure to buy regular products, be sure to read the manual before using it, and pay special attention to the precautions mentioned in the description.
