Explosion-proof filling machine used in explosive dangerous location matters needing attention

by:Jinzong Machinery     2020-06-16
Explosion-proof filling machine in note 1 SF300H - explosive dangerous location use B series explosion-proof type liquid filling scale is a kind of new automatic quantitative weighing equipment, approved by explosion-proof inspection institutions, with complex explosion-proof structure form. 2 the system of balance of the whole filling assembly by the explosion-proof inspection agency for approval, the user may not be changed without authorization system configuration parts and its connection mode. 3 products installed at the scene when using, must ensure that the filling balance of good grounding system perfect and reliable grounding. 4 flameproof components within the system, when using the maintenance must abide by the 'open' after power off warnings. Cable sheath diameter should satisfy phi - plus or minus 1 mm ( - to seal nominal diameter) 。 Field use should tighten gland nut. Aging sealing ring cable sheath should be timely replacement. Redundancy is introduced into mouth must use blind plug. 5 this Ann type electrical components within the system, the use of safety equipment and security grid maintenance, please refer to the corresponding operating instructions. Use the site as far as possible eliminate the influence of electromagnetic interference. 6 filling balance of the machine installation and maintenance, besides must carefully read the product user manual must be abide by GB50058 - at the same time 92 'the explosion and fire dangerous environment electrical device design specifications' and 'explosive dangerous location electrical safety regulations of the People's Republic of China' the relevant provisions. 7 when installation and maintenance, to be in after power wiring. 8 explosion-proof junction box on the unused service entrance should add wall seal. Grade claim that definition: explosion-proof equipment under prescribed conditions do not cause the surrounding explosive environment lighting electrical equipment. Divided into three categories Ⅰ class: the coal mine electrical equipment; Ⅱ class: in addition to underground coal mines, all of the other electrical equipments used in explosive gas environment. Ⅱ class and can be divided into A and B Ⅱ Ⅱ Ⅱ class C, sign Ⅱ B equipment can be applied to Ⅱ used conditions of equipment; Ⅱ C can be applied to the use of A and B Ⅱ Ⅱ conditions. Ⅲ classes: explosive dust environment except coal mine electrical equipment. Ⅲ class A: combustible --; Ⅲ class B: non conductive dust; Dust Ⅲ C: electrical conductivity. Maximum surface temperature: electrical equipment under the most adverse operating conditions within the specified range, can lead to explosive environment lighting electric equipment to any component of the highest temperature. The highest surface temperature should be lower than combustible temperature. For example: explosion-proof sensor environment of explosive gas temperature is 100 ℃, then the sensor in the most extreme working conditions, the maximum surface temperature of any component parts should be lower than 100 ℃. Products overview: liquid filling machine is a high degree of automation of packaging equipment, its main function is to liquid filling material automatically into the weight of the book set. Liquid filling machine in the process of filling materials can effectively avoid the overflow, greatly prevent material itself to the environment pollution, thus effectively labor protection to operators. The system work stable and reliable, simple operation, accurate filling. The filler is mainly composed of gun device, PLC system control part, weighing, filling machine, transportation equipment, etc. Jinzong Machinery, the main business products include liquid packaging automatic packaging equipment, automatic filling equipment specializing in the production of seller.
