Abstract
The utility model discloses a spindle assembly for a pulse generator. The spindle assembly comprises a piston, wherein an annular boss is arranged at the end where the piston is connected with a piston barrel, and the annular boss is provided with an overflow hole used for being communicated with an inner cavity of the piston barrel. The spindle assembly is simple in structure and reasonable in design, can play a role in protecting, prevents vibration and noise produced by overhigh pressure, and prevents signal strength from being affected.
Description
Technical field
The utility model relates to a kind of impulse generator main shaft, is specifically related to a kind of impulse generator spindle assemblies.
Background technology
At present, the pulse generating unit overflow valves that adopt with spring for underground logging more, the overflow valve of spring very easily is damaged when the down-hole adverse circumstances are worked, directly cause reduce the application life of pulse generating unit, and pulse generating unit is when work, power piston is too fast in the rising action of spraining while pressing, easily produce vibrations, noise, so very easily damage pulse generating unit, affect the intensity of signal, thus the impact normal operation.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, provides a kind of simple in structure, reasonable in design, can play a protective role, and prevents that mud pressure is excessive and the vibrations and the noise that produce, prevents from affecting the impulse generator spindle assemblies of signal strength signal intensity.
Its technical scheme is: the impulse generator spindle assemblies, comprise piston, and the link of described piston and piston cylinder is provided with annular boss, and described annular boss is provided with for being communicated with the spout hole of piston cylinder inner chamber.
Described annular boss is the carbide alloy boss.
Described spout hole comprises a plurality of.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, can play a protective role, and prevent that mud pressure is excessive and the vibrations and the noise that produce, prevent from affecting signal strength signal intensity.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, the impulse generator spindle assemblies, comprise piston 1, and described piston 1 is provided with annular boss 2 with the link of piston cylinder, and described annular boss 2 is provided with the spout hole 3 for being communicated with the piston cylinder inner chamber.
Described annular boss 2 is the carbide alloy boss.
Described spout hole 3 comprises a plurality of.
Install the hard alloy piece with annular boss 2 additional on power piston, a plurality of spout holes 3 are set on annular boss 2, can carry out overflow by spout hole 3 like this when mud pressure is excessive, can avoid like this piston 1 to move too fast and vibrations and noise that produce when rising builds the pressure, be not easy like this to damage pulse generating unit, do not affect the intensity of signal, guaranteed normal operation.
The utility model is simple in structure, reasonable in design, can play a protective role, and prevents that mud pressure is excessive and the vibrations and the noise that produce, prevents from affecting signal strength signal intensity.
