浅谈活络接头的开发与应用(国外英文资料) The domain of the magic domain is a dragon Talk about the development and application of active contact Pick to: the development and application of loose coupling solved the large movable water pump vessel in mountain area of rivers and lakes or reservoirs and different water level for water safety problems. Keywords: horizontal rotating sleeve; Vertical spiral sleeve; Roller; packing At present, the water pump boat is widely used in rivers and lakes or mountain reservoirs, mainly for simple and convenient, short period and low cost. The water quality is high, the water quality is good, it is not affected by the change of water level and fluctuation frequency. The difficulty of designing the pump boat is how to solve the influence of the connection hull and the piers on the shore. There are two ways to do this: Piers first, water pipe and the hull and the shore connection place each install a metal hose, when the water level change that hull movement and swinging the metal tube bending. The drawback of this scheme is that the bending degree of the metal hose is difficult to meet when the pipe size is more than 400mm and the length is limited. Second, water pipe and piers hull and the shore connection place the installation of a spherical joint, when the water level change ball joint rotation to adjust the balance of the hull. When the diameter of the pipe is large and the hull swaying is large, the ball connector does not apply. To solve the problem of large diameter water pipe hull and piers on the connection with the change of water level automatic adjustment problems, we design the adjustable joint development, respectively installed on the ship and shore a, realize the water floating boats bobbing along with the fluctuation of water level. The structure of a moving joint The structure of the active connection is shown in figure 1. It is composed of a cylinder is mounted vertical rotating sleeve 7, 12 for clearance fit, the two components in
