摩擦式矿井提升机,由于每根钢丝绳的几何尺寸、机械性能和摩擦轮纯槽直径的差异,以及安装调整等方面的原因,各绳张力会不断发生变化。当各绳张紧力相差较大时,会影响钢丝绳的使用寿命,甚至威胁提升安全。因此,安全规程规定,任一根提升钢丝绳的张力同平均张力之差不得超过±10%。通常,当钢丝绳张力差超过规定值时,是通过对连接在钢丝绳两端的液压螺旋调绳器(即平衡油缸)进行加压,缩短张力较小的钢
Frictional mine hoist, due to the geometry of each wire rope, mechanical properties and the difference between the diameter of the pure wheel friction wheel, as well as installation and adjustment reasons, the rope tension will continue to change. When the rope tension difference between the larger, it will affect the service life of wire rope, and even threatened to enhance safety. Therefore, the safety rules stipulate that the difference between the tension of any one of the hoisting ropes and the average tension shall not exceed ± 10%. Normally, when the rope tension difference exceeds a specified value, the hydraulic helical rope governor (ie, a balance cylinder) connected to both ends of the rope is pressurized to shorten the tension of the steel
