Explosion-proof equipment maintenance and skills
1. Simple first and later complicated. This experience has two meanings: First, when it comes to troubleshooting, it must first be handled with the easiest and most convenient way for maintenance personnel to use it, and then use complex, precise or unfamiliar methods; secondly, troubleshooting. In this case, first eliminate the intuitive, obvious, and simple common faults, and then remove the more difficult and unresolved problems.
2. First external debugging, then internal processing. External refers to the various switches, buttons, jacks, and indicators that are exposed outside the enclosure or seal of the electrical device. Internal refers to printed circuit boards, components, and various connection wires inside the enclosure or seal of electrical equipment. First external debugging, internal processing. It is the use of switches, buttons, knobs, etc. on the panel of the electrical equipment to debug and check the fault area without dismantling the electrical equipment. First of all, eliminate the failure caused by the external parts of the electrical equipment, and then repair the internal faults of the equipment to avoid unnecessary disassembly.
3. First mechanical, post-circuit. Electrical equipment is based on the electrical-mechanical principle. In particular, advanced equipment that integrates electromechanical devices, and mechanically and electrically cooperate with each other in terms of functions, is an integral two aspects. Often mechanical components fail, affecting the electrical system, and many electrical components do not function. Therefore, you should not be confused by the appearance of the phenomenon. You should look at the nature through the phenomenon. The failure of the electrical system is not entirely an electrical problem. It may be caused by the failure of the mechanical components. Therefore, the failure of the mechanical system is firstly repaired, and then the failure of the electrical part is eliminated. This will often result in a multiplier effect.
Wenzhou Chengan Explosion-proof Electrical Appliance Co., Ltd. tells you that: The explosion-proof junction box is casted with aluminum alloy shell, with plastic sprayed surface and beautiful appearance; steel pipe or cable wiring; cast aluminum alloy shell, surface sprayed; die-casting, beautiful appearance; The surface adopts the winding sealing structure, which has strong waterproof and dustproof properties; the wiring uses the increased safety type special terminal, the wiring is convenient, firm and reliable, and the current size has a variety of specifications for the user to choose arbitrarily; the direction of the inlet changes Multi-end, according to user requirements can be arbitrary match inlet and according to user requirements directly equipped with CBMJ series cable; in line with GB3836-2000, IEC60079 standard requirements.
Explosion-proof junction box series: The shell is made of impact-resistant glass fiber reinforced polyester, and all metal parts are corrosion-resistant. The joint between the lid and the base is designed as a concave-convex shape with a silicone rubber seal structure to ensure IP65 protection. It is used as a sub-line and connection for connecting various electrical equipment and instrumentation in the voltage 220V/380V line.
