Product Description
Tungsten carbide represents a versatile seal ring material that is broadly applied in all acidic environments. It is generally the material of choice in applications where distortion due to high pressures or rapid wear in abrasive environments are modes of premature failure. Tungsten carbide seals possess a unique combination of high fracture strength and high hardness that minimizes or eliminates these problems. Other favorable properties of tungsten carbide seals include high thermal conductivity values and low coefficients of thermal expansion. These kinds of wear parts lifetime more than other material. There are enjoy high reputation at home and aboard. These characteristics promote the efficient removal of heat and provide dimensional stability at higher operating temperatures.
Working principle :
The inclinometer pulse generator is inserted into the current limiting ring through the control (mushroom head) gap to change the annulus cross-sectional area therebetween. The mud pressure flowing in the drill pipe is changed to form a positive mud pressure pulse to realize signal transmission. The mud pressure flowing in the drill pipe is changed to form a positive mud pressure pulse to realize signal transmission. The pulse generator is driven by an electromagnetic mechanism to control a small control valve, thereby changing the pressure contrast of the upper and lower end faces of the piston. Then use the pressure generated by the mud flow to push the piston up and down, and the lifting rod (mushroom head) is intermittently inserted into the restrictor ring to form a positive mud pressure pulse.
