This year’s GDP is the worst data since the outbreak of the US financial crisis in 2014, and this may be the largest asset bubble in the past decade. At the recent high-level economic forum, some experts judged that the Chinese economy will successfully bottom out in the next two years. This is a very important decision-making judgment, that we are in the channel of bottoming out in the next two years.
The hardware and electromechanical industry must developTime of issue : 2016- 11-24
The hardware and electromechanical industry is developing very fast. The domestic markets in the traditional hardware and electromechanical industry are mainly concentrated in mechanical hardware, architectural hardware, decorative hardware, and daily-use hardware.
Hardware Interpretation: Matters needing attention for installation bolt connection of electromechanical equipmentTime of issue : 2016- 11-24
Bolt and nut connection is one of the most basic assembly in the electromechanical industry. When the connection is too tight, the bolt is prone to metal fatigue under the long-term action of mechanical force and electromagnetic force, and the connection of shear or thread slippage is too loose. To loosen the assembly between components and cause an accident. For the connection of bolts and nuts that conduct current in electrical engineering, not only the mechanical effect but also the electrothermal effect should be paid attention to, the crimping is not tight, the contact resistance increases, and the vicious cycle of heating-oxidation of the contact surface-increase of resistance occurs when energized , Until severe overheating, burning the joint, causing ground short circuit and disconnection accidents. For primary equipment and busbars, parallel groove clamps, T-clamps, equipment clamps and wiring of the connecting wires may cause accidents of different degrees.
