1. Carbide rotor product details:
The rotor of the continuous wave pulse generator is equipped with a
stator with the same number of blades as the rotor. When rotating,
the relative position of the rotor's overcurrent cross section and
the stator's overcurrent cross section changes to produce a
continuous sinusoidal pressure wave. The measurement data is loaded
with signals through the modulation system, the pressure waveform
changes are detected on the ground, and the measurement data is
calculated through decoding.
2. Product details of hard alloy stator:
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. This pulse generator
is driven by an electromagnetic mechanism to control a small
control valve, thereby changing the pressure contrast between the
upper and lower end faces of the piston. The pressure generated by
the mud flow is then used to push the piston up and down, and the
(mushroom head) is driven by the lifting rod to intermittently
insert the restrictor ring to form a positive mud pressure pulse.
Product advantages
Carbide stator and rotor have a series of excellent properties such
as high hardness, wear resistance, good strength and toughness,
heat resistance and corrosion resistance, especially its high
hardness and wear resistance, even at a temperature of 500 ℃ It
basically remains unchanged, and still has a high hardness at 1000
℃.
