Venta al por mayor de puentes grúa a prueba de explosiones Sevencrane and explosion-proof elevators are complex complete sets of electromechanical equipment that work in explosive and dangerous places. Explosion-proof performance is particularly critical during use. Nowadays, they have been widely used in places with explosive mixtures such as petroleum and chemical industries. Due to the special nature of this equipment’s work and environmental hazards, the state has implemented a compulsory supervision mechanism for it, thus effectively ensuring the safety of people’s lives and property and promoting the rapid development of the national economy.
La mejor opción para puentes grúa industriales a prueba de explosiones for explosion-proof cranes and explosion-proof elevators
(1) Explosion-proof cranes and elevators are a complete set of mechanical and electrical equipment, generally composed of metal structures, explosion-proof electrical equipment, connections between explosion-proof electrical appliances, mechanical or hydraulic transmission, mechanisms and parts, safety devices, etc. Generally, the explosion-proof function of a single explosion-proof electrical equipment mainly prevents electrical sparks, static sparks, high temperature of electrical shells, etc.; while the explosion-proof function of explosion-proof cranes and elevators during the movement of converting strong electrical energy into mechanical energy to carry heavy objects, it is necessary to prevent electrical sparks, Static sparks, high temperature of electrical casings, impact friction sparks, high temperature on the surface of mechanical equipment, etc.
(2) The Puente grúa a prueba de explosiones aprobado por la CE en venta of explosion-proof cranes and elevators is to take corresponding measures to control the generation of sparks, that is, to control and eliminate electrical sparks and mechanical sparks using corresponding explosion-proof technology so that they cannot ignite explosive materials in the environmental area where they are located. Gas mixtures and combustible dusts. Mechanical sparks use special non-spark materials in areas prone to dangerous sparks, control the amount of magnesium and titanium contained in the light alloy shell, and avoid collision and friction between mechanical parts with relative motion to achieve explosion protection, which is referred to as mechanical explosion-proof technology.
Explosion-proof measures for strong current equipment and circuits
Carts and trolleys, as well as lifting motors, electrical control cabinets, main power switches, electromagnetic brake coils or hydraulic drive motors, etc., generally use explosion-proof electrical equipment and cable wiring. Wiring and junction boxes, power switches, control and emergency stop switches, etc., generally use increased safety electrical equipment.
Explosion-proof measures for weak current equipment and circuits
Signal and overload sensing devices, etc., generally use intrinsically safe explosion-proof electrical equipment.
European standard ex-proof bridge crane suppliers for connecting cables
Non-intrinsically safe wiring on explosion-proof cranes generally uses rubber-sheathed round cables and compression nut-type introduction devices to prevent pull-out and reliably seal. No joints are allowed in the middle of the cables. If necessary, an explosion-proof junction box should be installed. Such as power circuits, control circuits, lighting circuits and audio signal circuits, etc.
