玻璃钢即玻璃纤维增强材料,目前已广泛应用于电气、交通、建筑和体育等各行各业。近几年,随着国内对玻璃钢材料的需求量日益增多,许多机械厂商开始研发生产玻璃钢的加工设备。玻璃钢生产线的牵引装置一般采用液压传动。对于液压传动的控制,如果采用传统继电器控制装 Fiberglass that is glass fiber reinforced materials, has been widely used in electrical, transportation, construction and sports and other industries. In recent years, with the increasing demand for FRP materials in China, many machinery manufacturers have begun to research and manufacture glass fiber reinforced plastic processing equipment. FRP production line traction devices generally use hydraulic drive. For hydraulic control, if using traditional relay control equipment
