The company issued a letter "about the configuration regulation of inductive proximity switch". In the regulation, the factory configuration of RL / CL is required to adopt normally open no mode, and the factory configuration of WL and HL is required to adopt normally closed NC mode. Some people are not clear about the reason why this configuration is adopted, and occasionally there are some cases that do not conform to the regulation The relationship between the selection of switch signal form and failure protection is explained.
Wind power generation is a promising new energy industry in China in recent ten years. At the end of 2010, China has become the largest wind power country in the world with installed capacity. In large-scale wind turbine, the realization of yaw system, main shaft braking and wind wheel locking depends on the hydraulic system with small volume and large function. Hydraulic technology has been widely used in the field of wind power generation.
