Abstract

The utility model discloses a can prevent into movable sealed oil of water and keep off in oil, it includes that tooth piece formula outer oil keeps off and the oil that sets up of heavy inslot cooperation respectively keeps off outer loop and inner ring, and the oil keeps off the clearance that forms between the cooperation of inner ring and oil fender outer loop, wherein keeps off fixed joint strip on the outside terminal surface of outer loop by oil, makes the short hypotenuse strip on it hug closely on the outside terminal surface of oil fender inner ring. The problem that shaft seal leakage steam enters the bearing box and is condensed into water to be mixed into oil is solved, and the bearing box has the characteristics of simplicity and convenience in installation and good sealing effect.

Description

Can prevent the active-type sealed oil blocking of intaking in the oil
The utility model relates to a kind of device that is used for the anti-runout leakproof oil of power station bearing of turbo generator set case, is a kind of active-type sealed oil blocking of intaking in the oil of preventing specifically.
In the known disclosed utility model patent technology, be 93218254.2 active-type sealed oil blockings as the patent No..It is to have adopted the outer oil catch of a fixing tooth chip, with oil catch outer shroud that is equipped with respectively in its deep gouge and interior ring, and interior ring with the outer oil catch of the gap of the radial fit end of outer shroud and gear piece formula radially deep gouge communicate, endoporus by interior ring and the outer oil catch of gear piece cooperates the installation rotary main shaft, when the gland packing leakage of steam turbine set, the body that the leaks gas gear piece and the interior ring of gap between the main shaft radial surface and active-type sealed oil blocking and the gap of outer shroud that outside the gear piece formula, keep off, enter into then and condense into water in the bearing housing and sneak into oil.Can heavy damage behind water of infiltration in the oil dynamically lubricating effect of turbine oil, jeopardize the safe operation of Turbo-generator Set, this is common existence of all power station and insoluble problem.
The purpose of this utility model is for solving the problem that above-mentioned technology exists, and a kind of active-type sealed oil blocking of intaking in the oil of preventing is provided, and has protected oil effectively.
For achieving the above object, the technical solution of the utility model is finished like this: a kind of active-type sealed oil blocking of intaking in the oil of preventing, comprise the oil catch outer shroud and the interior ring that are equipped with respectively in the deep gouge of outer oil catch of gear piece formula and body thereof, and the gap that the counterface of the outer end of ring and oil catch outer shroud the inner forms in the oil catch, wherein it has on the end face of the outside of oil catch outer shroud and fixedly installs sealing joint strip, the adhesive tape of its short hypotenuse is close on the outside end face of ring in the oil catch, the clearance channel of encircling in airtight oil catch outer shroud and the oil catch.
The technical solution of the utility model comprises that also described sealing joint strip is to be

Double-turnup shape or be Shape.
The characteristics that the utility model has compared to existing technology are: the sealing joint strip of setting up can effectively be controlled the passage of shaft-packing leakage, has protected oil, has solved this long-term insoluble problem of dynamically lubricating of the destruction turbine oil of intaking in the oil; Another characteristics are simple installations.Sealing joint strip can adopt fixedly connected or utilize and be

The slotted eye that the shape adhesive tape has directly cooperates and is installed on the oil catch outer shroud end face, makes it have convenient maintenance and replacement, characteristics efficiently.
Description of drawings:
Fig. 1 is for preventing the topology view of the active-type sealed oil blocking of intaking in the oil.
Fig. 2 is the sealing joint strip cross-sectional view.
Fig. 3 is another embodiment's view of Fig. 2.
In conjunction with the accompanying drawings to this novel specifying.
By shown in Figure 1, it has adopted the outer oil catch 1 of gear piece formula of original structure, installed respectively in oil catch outer shroud 2 and the oil catch in the cooperation deep gouge on its body and encircled 4, and utilize the outer end of ring 4 in the inner of oil catch outer shroud 2 and the oil catch cooperate between and the structural type in the gap that forms.Because the gland packing leakage of steam turbine set enters into along the gap between ring 4 and the oil catch outer shroud 2 in the oil catch and condenses into water in the bearing housing and sneak into oil, destroy the dynamically lubricating effect of turbine oil, for addressing this problem, have utilization and on the end face of the outside of oil catch outer shroud 2, be set with sealing joint strip 3.Sealing joint strip 3 is by being The double-turnup adhesive tape body shape (see figure 2) of shape utilizes the long edge strip of sealing joint strip 3 and oil catch outer shroud 2 outsides to fix, and another short hypotenuse bar is close on the outside end face of ring 4 in the oil catch, and the airtight passage of gland packing leakage.
Change as corresponding in the described sealing joint strip 3, all do not influence its connection matter, see Fig. 3, sealing joint strip 3 also can be made into and is Shape is utilized
