      升降平臺租賃限速器靈敏度受哪些因素影響?

      1、升降平臺租賃http://www.playloddenthinks.com/限速器繩槽磨損程度和鋼絲繩表面油污污染。限速器繩槽磨損嚴重,會減少鋼絲繩與繩槽的有效接觸面積,降低摩擦力;鋼絲繩及繩槽表面油污較多,會降低摩擦力,會導致限速繩張緊力不足,嚴重時會因有效提拉力不足而不能觸發并有效提起安全鉗。
      Lifting platform rental governor rope and wire rope groove wear on the surface of oil contamination. The governor rope groove badly worn, it will reduce the effective contact area between the rope and the rope grooves, reduce friction; rope and rope groove surface more oil will reduce friction, speed rope will lead to less tension, and in severe due to lack of effective pulling force can not effectively lift the trigger and the safety gear.

      2、升降平臺租賃限速器繩輪運轉情況,如果繩輪運轉不正常,有卡阻現象,繩與輪槽的摩擦力會增大,嚴重時會導致安全鉗誤動作。
      The governor sheave lifting platform operating lease, if the sheave is not functioning properly, there is jamming phenomenon, the friction of the rope and wheel groove increases, can cause serious safety gear malfunctions.

      3、升降平臺租賃預校彈簧銹蝕情況,彈簧長期處于反復伸縮狀態,當彈簧銹蝕較重,彈簧的預緊力會發生改變,將導致限速器整定速度發生變化,甚至動作速度值失真。
      Lifting platform rental corroded spring pre-school, spring long period of repeated stretching state, when the spring rust heavier spring preload will change, will lead to the governor speed setting changes, and even movement speed value distortion.

      4、升降平臺租賃http://www.playloddenthinks.com/張緊裝置,若張緊裝置對鋼絲繩的拉力不符合要求或裝置由于生銹等原因不能自由上下浮動,不能保證限速繩與繩輪間有足夠的張緊力,使限速繩與繩輪摩擦力減小,導致限速器動作靈敏度降低。
      Lifting platform rental tensioning device, if the tension device to pull the rope or a device does not meet the requirements because of rust and other reasons are not free to fluctuate, can not guarantee the speed limit between the rope and sheave has enough tension to make the governor rope and sheave friction is also reduced, resulting in governor tripping sensitivity.
