耐磨板磨損的原因及磨損分析

2018-10-19

錨桿鉆車的主要工作方式是鉆箱沿著鉆架的主體軌道做往復運動,來實現鉆桿的打孔過程。鉆箱在運動過程中相對于鉆架主體做摩擦運動,由于鉆架受偏載力,導致導向耐磨板在運動過程中受力不均勻,經常出現楔形現象。通過對導向耐磨板材料耐磨性能的分析,找到影響導向耐磨板磨損過快的主要原因。

鉆箱在運動過程中受偏載力的現象很嚴重,而且導向耐磨板接觸面上受到的力很不均勻,且從中部到下邊緣的力從零均勻增加到最大值q。由于導向耐磨板邊緣受到的力最大,且在運動過程中存在很嚴重的磨粒磨損現象,導致導向耐磨板的邊緣很容易受到磨損。

導向耐磨板正常工作時的工作類型為輕載低速,其潤滑主要是通過潤滑裝置中流出的液壓油為其接觸面進行潤滑,但是潤滑為邊界潤滑甚至干摩擦;同時由于工作環境的影響,導致其摩擦過程中有大量的磨粒存在于接觸界面間;同時導向耐磨板材料的硬度與鉆架主體材料的硬度相差很大,后者為前者的1.7倍。通過對鉆箱的運動分析,看到導向耐磨板工作時受力不均勻,在豎直方向上,導向耐磨板從中部到下邊緣的載荷從零均勻增加到最大值r1,這是導致導向耐磨板失效的重要原因之一;同時經過分析其磨損表面出現的磨粒磨損是導致導向耐磨板失效的另一個重要原因。根據以上的分析發現影響現在鉆架壽命的主要原因是導向耐磨板的材料,現有導向耐磨板材料的耐磨性太低,建議更換現有導向耐磨板的材料,從而延長鉆架的工作壽命,同時提高整機的開機時間,加快巷道的錨桿支護速度。
