Recently, the "Pure Machinery Overspeed Protection Device" designed by Dadu River Pubugou Power Plant has won the national patent for utility model (patent No. 2014 20139777.X). This is also the fifteenth patent that the factory has acquired. The pure mechanical overspeed device set up by hydropower units is the last protection line for the protection of water turbines, which can effectively avoid the increase of unit speed or even "flying car". It uses the flying pendulum installed on the big axle. When the speed of the unit is greater than the setting value, the flying pendulum moves to switch the oil circuit and start the emergency shutdown process of the unit to shut down the guide vane and the work gate of the inlet. In the process of unit operation, once the operation task needs to be close to the big axle, it is possible to mistakenly touch the protection device, resulting in the misoperation of the pure mechanical overspeed protection device, resulting in the unplanned outage of the unit.

Recently, ABB announced that it will provide more than 600 industrial robots to Great Wall Automobile Co., Ltd. for the new SUV white body welding workshop of Great Wall Automobile in Xushui Base Phase II New Factory, Hebei Province. Body welding is an important link that directly affects the body safety and overall performance. According to the agreement, ABB will provide many types of industrial robots including irb6640, irb7600 and irb2600 to Great Wall Vehicle, assembling an efficient, reliable and highly automated welding production line. At the same time, Great Wall Automobile is also cooperating with ABB white body business on the welding line, using the ABB Robot Welding solution, greatly improving the automation level and flexibility of the welding production line.

The author recently participated in the test drive of Dafa Copen, and the most surprising thing is that the coating process of engine hood and fender has been realized offline with the resin outer panel. Only the door is made of steel plate in order to meet the side impact standard, and the other body panels are painted off-line. Generally speaking, automobile body must go through three painting processes: electrodeposition coating, intermediate coating and surface coating. Therefore, the painting production line is very long. For Dafa Copen, only the electrodeposition coating line is 200 m. However, if no external coating is used, the painting process can be greatly shortened.
