Shandong fan damper suppliers, production advantages Marriott fan damper is the product of simple structure, located on the handle part into direct and positioning plate, easy to control; products are easy to process, will be used to link the structure of linear motion applications the circular motion of the toggle mechanism, the realization of the two-way force, especially for large damper; no complex calculations when equipped with an electric actuator. Due to the rotation direction of the handle and the electric actuator handle is consistent, as long as the two can be the same length. With favorable results, to solve the previous damper rotation is not flexible, strictly off, open issues and incomplete, particularly in addressing the major damper rotation is not flexible terms, the advantage is more prominent. Just make sure the blade axis and vertical interlocking handle it, due to fewer working parts, reducing the accumulated error; stiffness. The blade made of a double layer structure, increasing the blade stiffness, not easily deformed; opening and closing flexible regulation performance; significantly reduce the switching torque. Shandong fan damper suppliers, general fan industry production plant using the petal-type damper main body 1 by the heartbreaking, fitting 2, 3 strut, leaf 4, shaft 5, the sleeve 6, the linkage handle 7, circling 8, small shaft 9, the pulley 10, the pin 11, the support plate 12, cylinder 13 and handle the puck, pins and other components of each standard, the shaft is connected to one end of the slot with the blade, and the other end has one head and the handle linkage with the square hole linkage with a long handle and the other end opening hole, by circling the toggle linkage rotation handle, so the shaft is rotated 90 °, to achieve the purpose of opening and adjust the door closed.
