Abstract
The utility model relates to a mechanical sealed water joint formed by an upper cover, a sealing member a lower cover and a water joint core. The sealing member is disposed in a cavity of the upper cover; the water joint core is provided with a boss; a plane bearing (6) is arranged under the boss and over the lower cover; and a guide bearing and an adjusting shim are orderly assembled over the boss and under the upper cover. The mechanical sealed water joint is simply structured with rational interior design, safety, reliability and long service life.
Description
Technical field
The utility model belongs to a kind of probing water sending device, is specifically related to a kind of mechanical seal water swivel of geological drilling.
Background technology
Probing water swivel on the market at present, mostly use rubber washer or combination cushion rubber, in upper cover and lower cover, directly water swivel is sealed, this sealing due to rubber washer or combination cushion rubber directly contact with water swivel fuse, water swivel fuse rocks larger while rotating, rubber washer or combination cushion rubber easily damage, thereby have shortened the application life of water swivel.
Summary of the invention
The purpose of this utility model is just to provide a kind of improved mechanical seal water swivel, and it is simple in structure, and indoor design is reasonable, safe and reliable, long service life.
Realizing the technical scheme that above-mentioned purpose adopts is: mainly upper cover, seal, lower cover, water swivel fuse, consist of, it is characterized in that: in upper cover cavity, be provided with seal, on water swivel fuse with a boss, between boss below and lower cover, pack plane bearing 6 into, between boss top and upper cover, pack successively guide bearing into and adjust pad.
Described seal is the mechanical sealing member of stationary seal ring and the coupling of O RunddichtringO.
Described guide bearing is upper correcting bearing and lower correcting bearing arranged side by side, under cover and be provided with an annular groove, wherein pack the asbestos pad that outer rim contacts with the sealing of water swivel fuse into.
Upper and lower guide bearing and plane bearing are housed in this device, and its effect is to allow water swivel fuse energy Concentric rotation, can bear again axial and horizontal stressedly simultaneously, so move more steadily, can greatly increase application life.Lower cover is equipped with asbestos pad, in order to seal the lubrication oil of water swivel the inside.
The beneficial effect of utility model is:
1. use mechanical seal to seal water swivel, improved more than three times the application life of this new type water joint than traditional water swivel.
2. new type water joint is compared with traditional water swivel, significantly cost-saving.
3. reduced the number of times of changing water swivel, improved and creep into work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: upper cover 1, seal 2, adjustment pad 3, upper correcting bearing 4, lower correcting bearing 5, plane bearing 6, lower cover 7, water swivel fuse 8.
The specific embodiment
As shown in Figure 1, the utility model device is comprised of upper cover 1, seal 2, adjustment pad 3, upper correcting bearing 4, lower correcting bearing 5, plane bearing 6, lower cover 7, water swivel fuse 8.Upper cover 1 port has the screw thread being connected with elevator, and the seal groove of inner chamber processing is connected with the stationary ring of seal 2, has also been provided with O RunddichtringO simultaneously, and the liquid of water inlet is sealed.Plane bearing 6 is housed in lower cover 7, in order to load, put forward rotation and the weight of drawing drill rod boring tool, and in order to the water swivel own wt of loading, there is the seal groove of a dress asbestos pad lower cover 7 inside, in order to seal the lubricated wet goods of water swivel the inside.Set upper and lower correcting bearing 4,5 use in boss top of water swivel fuse 8 so that water swivel fuse 8 all the time with Concentric rotation, greatly reduce operating rocking, the bottom of water swivel fuse 8 connects and can rotate together with drilling tool with drilling rod with drilling rod on machine, the weight that can bear drilling rod and drilling tool, regulates pad 3 can make the inner one-tenth of whole water swivel compact state simultaneously.When directly entering water swivel fuse 8 and enter drilling rod again by water swivel upper cover 1 water inlet under the effect of drilling fluid in pump pressure, start rig, drilling rod drives 8 rotations of water swivel fuse, and the stationary ring of seal 2 does not rotate along with it, thereby has extended the application life of whole water swivel.
Claims (3)
1. a mechanical seal water swivel, mainly by upper cover, seal, lower cover, water swivel fuse, formed, it is characterized in that: in upper cover cavity, be provided with seal, on water swivel fuse with a boss, between boss below and lower cover, pack plane bearing 6 into, between boss top and upper cover, pack successively guide bearing into and adjust pad.
2. by mechanical seal water swivel claimed in claim 1, it is characterized in that: described seal is the mechanical sealing member of stationary seal ring and the coupling of O RunddichtringO.
3. by mechanical seal water swivel claimed in claim 1, it is characterized in that: described guide bearing is upper correcting bearing and lower correcting bearing arranged side by side, under cover and be provided with an annular groove, wherein pack outer rim into and seal with water swivel fuse the asbestos pad contacting.
