钻井泥浆泵橡胶—钢凡尔是一种消耗量很大的易损配件。据我局初步统计,每年消耗量约在13200只以上,消耗合金结构钢220吨左右。成本按每只116元计算,共计约150多万元。而且橡胶—钢凡尔在化学和机械两方面的联合作用下,使用寿命很低,一般工作时间为70~100小时。因此凡尔拆修频繁,工人劳动强度大,在一定程度上影响了钻井速度和成
Drilling Mud Pump Rubber - Steel Versailles is a consumable and consumable part that consumes a lot. According to the preliminary statistics of our bureau, the annual consumption is about 13,200, consuming 220 tons of alloy steel. The cost of 116 yuan per calculation, a total of about 150 million. And rubber - steel where Seoul in the chemical and mechanical aspects of the combined effect of low life expectancy, the general working time of 70 to 100 hours. Therefore, frequent demolition of Versailles, workers labor-intensive, to a certain extent, affected the drilling speed and become
