Abstract
The utility model relates to the technical field of oilfield production engineering, belonging to a rotary and reciprocating motion dynamic sealing device for underground horizontal drilling machine, which is designed based on overcoming the problems of large possibility of abrasion of rotary shaft and aging of sealing ring, low pressure bearing ability and poor sealing effect in the current sealing device. The rotary and reciprocating motion dynamic sealing device is composed of a rotary shaft 1, a sealing body 2, a roller bearing 3, a sealing seat 4, an O-shaped sealing ring 5, a gasket ring 6, a sealing nut 7, a rotary Glyd ring 8, a spring tension ring for shaft 9 and a rotary shaft sleeve 10, wherein sealing member modules consisting of the roller bearing 3, the sealing seat 4, the O-shaped sealing ring 5, the gasket ring 6, the Glyd ring 8 and the spring tension ring for shaft 9 are sequentially sleeved on the rotary shaft 1 and then sleeved inside an inner hole of the sealing body 2; the device has the advantages of simple structure, convenient installation and disassembly, high pressure resistance, good sealing effect, etc.
Description
Technical field:
The utility model the utility model relates to the oil field technical field of oil production engineering, belongs to a kind of down-hole horizontal boring machine with rotating and reciprocating dynamic seal apparatus.
Background technique:
At present, be used for various bodies with holes, rotatingshaft and pass that this hole rotates and the dynamic seal apparatus of axially reciprocating mainly contains: stuffing seal, seal ring seal arrangement etc.The former offers annular groove on body with holes, fill felt or other sealing filler in the groove, utilize felt or filler to stop up gap between rotatingshaft and the body with holes, thereby realize the effect of sealing, its defective is that felt or filler are worn easily, pressure-bearing is low, sealing effect is relatively poor; The latter utilizes the resiliently deformable of rubber seal to stop up gap between body with holes and the rotatingshaft, and its defective is that rotatingshaft weares and teares easily, seal ring is aging easily, pressure-bearing is low, sealing effect is relatively poor.
Summary of the invention:
That the purpose of this utility model provides is simple in structure, maintenance and easy to use, pressure-bearing is high, a kind of down-hole horizontal boring machine of good sealing effect is with rotation and reciprocating movement sealing device.
To achieve these goals, this model utility is by the following technical solutions: it by rotatingshaft, sealed body, rolling bearing, sealing seat, " O " RunddichtringO, gasket ring, seal pressure cap, rotation lattice enclose, the axle form with spring tension circle and rotary sleeve; Wherein be sleeved on successively in the endoporus of sealed body by the seal assembly that rolling bearing, sealing seat, " O " RunddichtringO, gasket ring, rotation lattice enclose, axle is formed with the spring tension circle, the rotation lattice enclose, axle is packed in the sealing seat with the spring tension circle, " O " RunddichtringO is enclosed within on the sealing seat, be contained in the seal pressure cap after rotary sleeve is contained on the rotatingshaft, seal pressure cap is connected with sealed body by screw thread.
The rotation lattice enclose and axle is preferably 2～6 with spring tension circle number.Being full of lubricating grease in the groove of rotary sleeve is the high temperature extreme pressure grease.Rotary sleeve is replaceable part, and material can be a nylon 1010, also can be teflon.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, installation and removal are convenient, pressure-bearing is high, good sealing effect, and can improve the success rate of down-hole horizontal boring.
