Abstract
The utility model relates to a deflector-type sealing device of a pumping unit gear box, which mainly solves the problem that the sealing effect at the joint of the prior output shaft and input shaft and the box is poor. The sealing device is characterized in that: the gear box (2) at the root of a shaft (1) is connected with two halves of circular sealing cover (3) by bolts; the sealing cover (3) is connected with two halves of circular sealing ring (5) by two halves of circular pressing plate (4); the sealing cover (3) is provided with a longitudinal oil-returning slot (7) corresponding to a bolt (6) at a lower end; the bolt (6) is provided with oil return holes (8) in the radial direction and the axial direction which are communicated; the oil return oil (8) is communicated with the gear box (2) by an oil pipe. The deflector-type sealing device of the pumping unit gear box is characterized by good sealing effect at the joint of the output shaft and the input shaft and the box.
Description
Technical field:
The utility model relates to oil recovery field, oil field oil pumping unit reduction gearbox used seal arrangement, especially oil pumping unit reduction gearbox flow guide type seal arrangement.
Background technique:
In oil recovery field, oil field, beam pumping unit is used widely in the oil field.Speed reducer is the important composition of beam pumping unit.And existing speed reducer exists the problem of output shaft and input shaft and casing joint sealing effect difference because of reasons in structure, needs often maintenance, has influenced the normal operation of speed reducer, goes back befouling environment, thereby influences the recovery rate of oil well.
The model utility content:
In order to solve the problem of existing output shaft and input shaft and casing joint sealing effect difference, the utility model provides a kind of oil pumping unit reduction gearbox flow guide type seal arrangement, and this oil pumping unit reduction gearbox flow guide type seal arrangement has the characteristics of output shaft and input shaft and casing joint good sealing effect.
The technical solution of the utility model is: this oil pumping unit reduction gearbox flow guide type seal arrangement comprises deceleration box and axle, be connected with two halves circular seal lid by bolt on the axle root deceleration box, be connected with the two halves circular seal ring by two semicircle pressing plates in the sealing cover, corresponding lower end bolt has vertical oil-return groove in the sealing cover, the radial and axial spill port that communicates is arranged on the bolt, and spill port is connected by in oil pipe and the deceleration box.
Be connected with two semicircle flinger rings on the pressing plate inner shafts in the such scheme, the flinger ring cross section is a triangle.
The utlity model has following beneficial effect: this oil pumping unit reduction gearbox flow guide type seal arrangement is owing to take such scheme, by oil-return groove in the sealing cover and the spill port on the bolt, effectively reclaimed the oil that leak output shaft and input shaft and casing joint, guarantee the continuous operation of speed reducer, improved the sealing effect of output shaft and input shaft and casing joint, minimizing is to the pollution of environment, improved the utilization ratio of pumping unit, prolong the engineering time of speed reducer, and compact structure, help applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-axle among the figure, 2-deceleration box, 3-sealing cover, 4-pressing plate, 5-seal ring, 6-bolt, 7-oil-return groove, 8-spill port, 9-flinger ring.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this oil pumping unit reduction gearbox flow guide type seal arrangement comprises deceleration box 2 and axle 1, be connected with two halves circular seal lid 3 by bolt on the axle 1 root deceleration box 2, be connected with two halves circular seal ring 5 by two semicircle pressing plates 4 in the sealing cover 3, corresponding lower end bolt 6 has vertical oil-return groove 7 in the sealing cover 3, the radial and axial spill port that communicates 8 is arranged on the bolt 6, spill port 8 is connected by in oil pipe and the deceleration box 2, be connected with two semicircle flinger rings 9 on pressing plate 4 inner shafts 1, flinger ring 9 cross sections are triangle.
During actual the use, at first flinger ring 9 is connected on the axle 1, by pressing plate 4 two halves circular seal ring 5 is connected in the sealing cover 3 by bolt then, and two halves circular seal ring 5 contacts with spool 1, prevent that dust from entering.At last again with two halves circular seal lid 3 at axle about in the of 1, and be connected on the deceleration box 2 by bolt 6, the sealing cover 3 of taking back oil groove 7 is connected below the axle 1, oil-return groove 7 is perpendicular to axle 1.When speed reducer moves, drop in the sealing cover 3 from output shaft and input shaft and casing joint oil spill, flow in the spill port 8 on the bolt 6 by oil-return groove 7 then, flow to speed reducer by oil pipe at last.Because of in sealing cover, having increased oil-return groove 7, on the bolt 6 of lower end, have spill port, so effectively reclaimed the oil that leak output shaft and input shaft and casing joint, guarantee the continuous operation of speed reducer, improved the sealing effect of output shaft and input shaft and casing joint, reduce pollution environment, improved the utilization ratio of pumping unit, prolong the engineering time of speed reducer, and compact structure, help applying.
Claims (2)
1. oil pumping unit reduction gearbox flow guide type seal arrangement, comprise deceleration box (2) and axle (1), it is characterized in that: axle (1) root deceleration box (2) is gone up by bolt and is connected with two halves circular seal lid (3), be connected with two halves circular seal ring (5) by two semicircle pressing plates (4) in the sealing cover (3), corresponding lower end bolt (6) has vertical oil-return groove (7) in the sealing cover (3), the radial and axial spill port that communicates (8) is arranged on the bolt (6), and spill port (8) is connected by in oil pipe and the deceleration box (2).
2. oil pumping unit reduction gearbox flow guide type seal arrangement according to claim 1 is characterized in that: be connected with two semicircle flinger rings (9) on pressing plate (4) inner shafts (1), flinger ring (9) cross section is a triangle.
