钻井泥浆泵凡尔是一种年消耗量很大的易损零件。据有关单位的调查,目前成批生产的橡胶-钢凡尔使用寿命相当低,在化学和机械两方面的联合作用下,一般工作70-100小时后就失去密封作用(见图1A、B及C)。凡尔的迅速损坏和经常拆换,既加大了工人的劳动强度,又在一定程度上影响钻井速度 Drilling mud pump Versail is a consumable part that consumes a lot of energy. According to the investigation of the relevant units, the current batch production of rubber-steel, Versailles, has a very low service life. Under the combined action of chemical and mechanical work, it usually lacks sealing effect after 70-100 hours of operation (see Figures 1A, B and C). The rapid destruction and frequent demolition of Versailles not only increased the labor intensity of workers, but also affected the drilling speed to a certain extent
