Abstract
A dual piston vibroseis vibrator concerning oil seismic exploration is disclosed, which includes a gland 1, a wear-resistant set 2, a piston 3, an upper oil cavity 4, an upper oil channel 5, a lower oil channel 6, a hammer 8, a lower oil cavity 7and an oil drainage hole 9. The pistons 3 are arranged in the upper and lower blind holes of the hammer 8 respectively. The upper oil channel 5 and the lower oil channel 6 are provided in the hammer 8. The upper oil cavity 4 is connected with the upper oil channel 5 and the lower oil channel 7 is connected with the lower oil channel 6. The hammer 8 is fixed by the gland 1. The vibrator can improve the pressure bearing by the piston gland effectively, decrease the difficulty of the design, increase the process crafts and reduce the volume of the working oil channel to improve the vibratility of the dual piston vibroseis vibrator.
Description
Relate to the field:
The utility model relates to a kind of oil seismic exploration equipment, specifically, is dual Piston vibroseis Vib..
Background technology:
The vibroseis Vib. that uses mostly is traditional piston cylinder operator at present, and as shown in Figure 1, traditional vibroseis Vib. mainly contains hammer body, piston, copper sheathing, gland, seal, securing member composition.Hammer body is a rectangle steel block, and there is a garden through hole at the center; Piston and piston rod are cylindrical, and piston diameter equates with Circularhole diameter on the hammer body and greater than diameter of piston rod, undergauge arranged on the piston rod; Copper sheathing is a hollow cylinder, and the area difference that exists between its face area size and piston and piston rod equates that oilhole is arranged on the copper sheathing.As above figure after the assembling, hammer body, piston and piston rod thereof and copper sheathing have oil duct in conjunction with forming the hollow cylinder working oil chamber on the hammer body, be connected mutually with oil duct on the copper sheathing, by the undergauge on the piston, working oil chamber are communicated with extraneous operation valve.Piston rod is fixed with miscellaneous part.
During work, extraneous operation valve control hydraulic oil enters working oil chamber by oil duct, as epicoele, the acting force of hydraulic oil with act on simultaneously above the piston and the copper sheathing lower surface on, motionless because of piston rod, under the effect of power, copper sheathing drives hammer body by gland and moves upward, lower oil cavitie is diminished, and fluid is wherein discharged by oil duct.Otherwise hydraulic oil enters lower oil cavitie, and hammer body will move downward, and the fluid of upper oil cavitie is discharged by oil duct.
The problem of Cun Zaiing as can be seen:
1, the transmission of power is by copper sheathing, gland.Along with the increase that the vibroseis vibration is exerted oneself, the power that gland bears is also with increasing, and the Design and Machining difficulty increases, the sealing difficulty.
2, the oil duct volume is big, makes Vib. (resonance frequency) reduction frequently admittedly, is unfavorable for that the vibrations performance of Vib. improves.
Technology contents
The purpose of this utility model is to provide a kind of can effectively improve the pressure that piston gland bears, and reduces design difficulty, improves processing technology, reduces the volume of work oil duct, thereby reaches the dual Piston vibroseis Vib. that improves Vib. vibrations performance.
The utility model is achieved in that
Comprise gland 1, wear-resistant sleeve 2, piston 3, upper oil cavitie 4, go up oil duct 5, following oil duct 6, hammer body 8, lower oil cavitie 7, drain tap 9, be equipped with piston 3 respectively in the upper and lower blind hole of hammer body 8, have oil duct 5, following oil duct 6 on the hammer body 8, upper oil cavitie 4 is communicated with last oil duct 5, lower oil cavitie 7 is communicated with following oil duct 6, and hammer body 8 is fixing by gland 1.
The utility model also adopts following technical scheme:
Between hammer body 8 and the piston 3 wear-resistant sleeve 2 is arranged.
Hammer body 8 is the rectangle block, and there is the garden blind hole in two laterally zygomorphic, same axle center at the center.
Piston 3 and piston rod are cylindrical, and piston 3 diameters equate with Circularhole diameter on the hammer body 8 and greater than diameter of piston rod.
Also have drain tap 9 on the hammer body 8.
Advantage of the present utility model is:
1, upper and lower two pistons have replaced former piston to maintain static, and the thrust that hydraulic coupling produces acts on respectively on piston and the hammer body, no longer is that conventional vibrator just acts on the hammer body by the transmission of copper sheathing, gland like that.Reduce the Design and Machining difficulty of Vib., improved manufacturability.
2, the oil duct volume is compared greatly with conventional vibrator and is reduced, with homemade KZ28 type vibroseis is example, because structure and technological reason, conventional vibrator work oil duct volume is about 560ml, novel vibrating device work oil duct volume is about 280ml, reduced 50%, helped improving Vib. frequency (resonance frequency) admittedly, thereby improved the vibrations performance of Vib..
3, the seal sealing is the fluid that leaks, and pressure is close to zero, and design difficulty reduces, ILS.
4, the gland power of bearing is draining pressure, and is almost nil, and the power that the conventional vibrator gland bears to be vibrations exert oneself, be example with homemade KZ28 type vibroseis, the power that gland bears is 28 tons.Therefore the novel vibrating device improves the force-bearing situation of gland greatly.
Description of drawings
Fig. 1 is the structural representation of conventional vibrator;
Fig. 2 is a structural representation of the present utility model.
Concrete enforcement
Shown in Fig. 2 structural drawing, novel vibrating device: mainly contain hammer body 8, piston 3, gland 1, seal, securing member composition.Hammer body 8 is a rectangle steel block, and there is the garden blind hole in two laterally zygomorphic, same axle center at the center; Piston 3 and piston rod are cylindrical, piston 3 diameters equate with Circularhole diameter on the hammer body and greater than diameter of piston rod, as above scheme after the assembling, hammer body 8, piston 3 are in conjunction with forming cylindrical working oil chamber, have the work oil duct on the hammer body 8, promptly go up oil duct 5, following oil duct 6, upper and lower oil pocket 4,7 is communicated with extraneous operation valve.Piston rod is fixed with miscellaneous part.Drain tap 9 communicates with extraneous hydraulic oil.
During work, extraneous operation valve control hydraulic oil enters working oil chamber by oil duct, as upper oil cavitie 4, the acting force of hydraulic oil will act on below the piston 3 and on the hammer body 8 simultaneously, motionless because of piston rod, under the effect of power, hammer body 8 moves downward, lower oil cavitie 7 is diminished, and fluid wherein is by oil duct 6 discharges down.Otherwise hydraulic oil enters lower oil cavitie 7, and hammer body 8 will move upward, and the fluid of upper oil cavitie 4 is discharged by oil duct 5.
