Reference Illustrate:
High-precision tungsten-cobalt carbide balls are widely used in oil drilling, deep-sea drilling pumping ball, ball seat, which is also the most critical component of the pump. Due to the harsh working environment and conditions in the oil drilling industry, it is usually contained in sand wells, heavy oil wells and high-pressure anti-sloping wells with some corrosive substances such as water, various gases, waxes, sands, etc. The oil is extracted from several hundred or even thousands of layers, which requires the valve ball and the valve seat to have good sealing, wear resistance and corrosion resistance (the valve ball and the valve seat are combined and then vacuumed to an absolute pressure of 0.36kgN). Below /cm, the absolute pressure value does not change within 10s.
