Sander Sander has the same utility with Grinder , or Polisher. Sander is installed at the end of Industrial Robot, but sander is hard to control the force onto workpiece, it needs our Force Control System, Constant Force Actuator, or active contact flange to control the force flexibly. Only the sander is not enough to finish the grinding polishing process in a high efficiency and get a better surface effect. So force control system is essential and necessary part for the whole sanding system. industrial Electric sander, industrial pneumatic sander, industrial disc sanders DARU Technology (Suzhou) Co., Ltd. , https://www.darudfc.com
What is explosion-proof distribution box?
The distribution box is a mass parameter on the data. It generally constitutes a low-voltage electrical connection according to the electrical wiring. The switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are required to be assembled in enclosed or semi-enclosed metal cabinets or screen panels to constitute low-voltage distribution. box. During normal operation, the circuit can be switched on or off by means of a manual or automatic switch. The explosion-proof distribution box is a kind of distribution box with better quality and can be used in flammable and explosive places.
China's first explosion-proof distribution box:
China has not produced explosion-proof electrical appliances many years ago. In 1987, China Huarong Explosion-proof Electrical Appliances Group (early called Liushi Explosion-proof Electrical Appliance Factory) was established and produced the first explosion-proof distribution box in China. China Huarong soon became the leader in the explosion-proof industry.
Explosion-proof distribution box types:
Explosion-proof distribution box is divided into: explosion-proof power distribution box for factory and explosion-proof power distribution box for mine according to applicable environment. The explosion-proof grade for the factory is Class II; the mine is Class I. The two explosion-proof distribution boxes have strict grades and cannot be used with each other.
Explosion-proof distribution box material development: the first explosion-proof distribution box shell is formed by aluminum alloy die-casting, and later due to special customers such as offshore oil fields also need waterproof anti-corrosion distribution box, so slowly have stainless steel explosion-proof power distribution box. There are two more materials. One is carbon steel material, and the other is engineering clinker material. Carbon steel materials are generally used to make large-scale explosion-proof power distribution cabinets and non-standard explosion-proof power distribution boxes, and the use of customers does not have much requirements for waterproof anti-corrosion. So we chose carbon steel. The project clinker material is actually the outer shell of the aluminum alloy and is covered with a layer of engineering clinker. This can also achieve the effect of waterproof and anti-corrosion. Customers who want to purchase stainless steel materials can choose engineering plastic materials because of high cost and high price.
Explosion-proof distribution box development will be better:
Because the country pays more and more attention to the safety of factory production. Therefore, the development of explosion-proof electrical appliances, especially explosion-proof distribution boxes, will become better and better.
