数字化螺杆式启闭机的研究与应用

The Engineering Research and Application of the Digital Screw Refrigerating Machine

螺杆式启闭机是水利工程上的重要设备之一。近年来由于螺杆式启闭机存在的问题,即过载保护和开度装置精度误差较大,造成性能不稳定,时有螺杆压弯或闸门启升越位等事故发生。为彻底解决螺杆机的技术难题,研究试制了数字化螺杆式启闭机。即利用小曲轴把蜗杆上的直线力变成小曲轴扭矩,从而达到测量闸门启闭力的目的;在高速轴上利用小模数涡轮蜗杆啮合,实现高速轴的转数输出给编码器,从而达到测量闸门开度的目的。

The screw refrigerating machine is one of the important device in water engineering.Recent years,because of some problem existed in screw refrigerating machine,such as large accuracy error in overload protection and opening equipment,leading to a low stability and some accident about screw bending.In order to solve these problem,we manufacture the digital screw refrigerating machine,this machine change the linear load on the worm into small bent axle torque with use of small bent axle.As a result,we can measure the opening power on the gate.In the super-speed shaft,using small module turbine worm,realize the axis rotation output to the encoder.As a result,we can measure the opening size on the gate.
