Tungsten Carbide Downhole Tool Wear-Resistant Parts Mwd Pulse
Generator Parts
Detailed 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.
Product Feature of tungsten carbide Main Valve Core:
1. Excellent abrasion resistance
2. High wear resistance
3. High fractural strength
4. high thermal conductivity
5. Small heat expansion co-efficient
Working principle of tungsten Main Valve Core:
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.
