随着煤炭、石油行业向着深部、复杂地层发展,煤矿石油机械工作条件更加恶劣,由此造成的停工停产等问题频繁发生,严重制约了煤炭和石油开采的效率,造成了大量的材料、能源和人力浪费。因此国内外对提高石油、煤炭机械和发电设备中关键部件的寿命和安全性,都给予高度重视。 With the development of coal and oil industries in deeper and complex strata, the working conditions of coalmine oil machinery are even worse, and the problems such as stoppage of production and production stop frequently occur, severely restricting the efficiency of coal and oil exploration, resulting in a large amount of materials, energy and Human waste. Therefore, both domestic and foreign countries attach great importance to improving the life span and safety of key components in petroleum, coal machinery and power generation equipment.
