Abstract
The utility model discloses a protective barrel for a pulse generator. The protective barrel comprises a barrel body arranged at the end of a piston barrel and respectively connected with a piston and an outer shell, a plurality of annular filtering grooves are formed in the surface of the barrel body, and the width of each filtering groove is 0.5mm. The protective barrel is simple in structure and reasonable in design, can protect the power piston, prevents slurry from directly scouring the piston, and facilitates maintenance and observation, and the service life of the protective barrel can be prolonged.
Description
Technical field
The utility model relates to a kind of impulse generator protective device, is specifically related to protection cylinder for a kind of impulse generator.
Background technology
At present, good and the bad work that directly has influence on pulser of down-hole pulser punching oil, and pulser need to vacuumize, rush oil for a long time, work by piston pump, oil extraction, so the sealing of piston cavity is of crucial importance, be in the environment of mud due to pulse generating unit integral body when well logging in, contain particle not of uniform size in mud, the as easy as rolling off a log power piston place that enters pulser of these particles destroys sealing ring and sealing surface.Easily like this cause poorly sealedly, need to stop producing and being keeped in repair, have a strong impact on normal operation, affected operating efficiency, also increased maintenance cost.
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 protect power piston, prevents the direct erosion piston of mud, is convenient to maintenance and observes, protection cylinder for the impulse generator that can increase the service life.
Its technical scheme is: impulse generator is with protecting cylinder, comprise the end that is arranged on piston cylinder to pass through the cylindrical shell that the rib cylinder is connected with shell, and described drum surface is provided with the lautertuns of a plurality of ring-types, and the width of described lautertuns is 0.5mm.
Described cylindrical shell comprises the straight tube end be set on main shaft and the tapering point be connected with shell.
Described lautertuns is 22.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, can protect power piston, and prevent the direct erosion piston of mud, be convenient to maintenance and observe, can increase the service life.
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, impulse generator is with protecting cylinder, comprise the end that is arranged on piston cylinder to pass through the cylindrical shell that the rib cylinder is connected with shell, and described drum surface is provided with the lautertuns 1 of a plurality of ring-types, and the width of described lautertuns 1 is 0.5mm.
Described cylindrical shell comprises the straight tube end 2 be set on main shaft and the tapering point 3 be connected with shell.
Described lautertuns 1 is 22.
When work, straight tube end 2 is set on main shaft, tapering point 3 is connected with piston cylinder with shell by the rib cylinder, by changing choke valve and the gap (monolateral apart from 0.5mm) of protecting cylinder, process the wide lautertuns 1 of 22 road 0.5mm on cylindrical shell, in the situation that guaranteed mud, can filter makes the paired pulses generating means very harmful, the particle footpath is greater than the impurity of 0.5mm, these lautertuns 2 can play a role in filtering, in order to avoid bulky grain mud or impurity destroy the sealing ring of piston, thereby extend its application life; For the ease of observing the stroke of pulser, at pulse generating unit, go into the well, or the number that can observe lautertuns by choke valve and the relative motion of protection cylinder during maintenance, confirm that whether the work of pulse generating unit is normal.
The utility model is simple in structure, reasonable in design, can protect power piston, prevents the direct erosion piston of mud, is convenient to maintenance and observes, and can increase the service life.
