Abstract
The utility model relates to a full-contact hermetic seal oil catch, which belongs to the seal oil catch device of large-sized high-speed rotary machines, steam turbines, hydraulic turbines, generators and assistant equipment. The utility model is characterized in that a spigot slot is formed in a full-contact seat ring, and an oil baffle plate slide block is slid in the groove. Steps on the slide block are matched with the spigot in the slot to limit or reduce infinite amount of feed of the oil baffle plate slide block. The oil baffle plate slide block, made of non-metallic materials, has the characteristics of abrasion resistance, high temperature resistance and self-lubrication, is capable of fully contacting the rotary shaft surface without damaging the rotary shaft and preventing a mass of lubricating oil from leaking. The side of the full-contact seat ring is provided with a hermetic seal auxiliary seat ring; air supply is led in by air pipes and passes through air intakes to form an air wall and to prevent a small quantity of lubricating oil from leaking. The bottom of the full-contact seat ring is provided with an oil return hole for lubricating oil entered in the hermetic seal chamber to reflow into the oil box. The utility model is capable of completely preventing the problem of external leakage of lubricating oil of large-sized high-speed rotary machines and effectively preventing water with oil; the utility model also has the advantages of simple and convenient assembly and disassembly and lightened workload.
Description
Affiliated technical field:
The utility model relates to a kind of full contact hermetic seal oil catch, belongs on the sealed oil catch device of large high-speed rotating machinery, steam turbine, water turbine, generator and complete auxiliaries.
Background technique.
At present, known oil catch basic structure is to be inlayed by seat ring, copper tooth, wool felt or nonmetallic material processing to form.Be installed on the lubricating oil tank of large high-speed rotating machinery, steam turbine, water turbine, generator and complete auxiliaries.Prevent that when rotation work lubricant oil is to external leakage.Block water and dust enter in the lubricant oil.But rotating machinery for the operation of beating of irregular ellipse, bumps mill to making with the life of existing oil catch tooth and hair in the high speed rotating running, cause the oil catch excesssive gap, and a large amount of oil leaks or Water in oil make oily emulsion deterioration.Not only pollute working environment, and cause fire easily.Water in oil also causes bearing burnt easily, brings hidden danger to safety in production.Also need frequent repairing, replacing or oil strain in addition.Also to increase the weight of direct labor's labor intensity during each the maintenance from the gap between new adjustment oil catch and the rotatingshaft.
Summary of the invention
To bump the mill post gap in the existing oil catch work excessive in order to solve, and can not effectively prevent the problem of oil leak and Water in oil.The utility model provides a kind of full contact hermetic seal oil catch.Full contact hermetic seal oil catch not only can solve existing oil catch and bump the excessive problem of mill post gap at work, and dismounting easily, need not to adjust and rotatingshaft between the gap, alleviate direct labor's labor intensity.
The technological scheme that the utility model technical solution problem adopts: contact the seat ring bottom entirely at full contact hermetic seal oil catch and open a seam groove, the groove inner bottom part studs with several five equilibrium springs, is screwed.Nonmetal oil baffle slide block is slipped in the seam groove after by seam groove dimensioned.Oil baffle slide block step matches with the groove inner stopper, is used to limit radial feeds, reduces or avoids the endless feeding of oil baffle slide block.The oil baffle slide block is divided into several separation structures such as grade by the circle diameter size, and when rotatingshaft running work, each oil baffle slide body can radially bounce back or radially hold out against under the effect of seam groove bottom spring.The oil baffle slide body adopts nonmetallic composite, has necessarily wear-resistant, high temperature resistant and self lubricity.Can not damage the rotating shaft surface with the comprehensive engagement of rotatingshaft surface, reach and prevent a large amount of oil leak purposes.At full contact seat ring sidepiece a hermetic seal counter-base circle is installed.Inside has several inlet holes (not waiting by diameter quantity).Stud with gas-tpe fitting at hermetic seal counter-base circle top, in order to introduce source of the gas.Source of the gas blows out through several inlet holes simultaneously by gas-tpe fitting, and stepless action is in the rotatingshaft surface, forms the gas wall in the hermetic seal chamber, reaches to prevent micro lubricating oil leakage purpose.Have spill port in full contact seat ring bottom, the less amount of lubrication oil that is used to enter the hermetic seal chamber is back in the former fuel tank.
The beneficial effects of the utility model are that the lubricant oil that can prevent large high-speed rotating machinery, steam turbine, generator, water turbine and subsidiary engine fully effectively prevents Water in oil to external leakage.Install simple and conveniently, alleviate workman's working strength.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1, be longitudinal section of the present utility model tectonic maps
1. oil box among the figure, 2. full contact seat ring, 3. bolt, 4. steam pipe connect, 5. bolt, 6. inlet hole, 7. hermetic seal counter-base circle, 8. spill port, 9. spring, 10. screw, 11. oil baffle slide blocks, 12. rotatingshafts, 13. seam grooves.
Embodiment:
In Fig. 1: open a seam groove (13) groove inner bottom part to stud with several five equilibrium springs (9) fixing by screw (10) in full contact seat ring (2) bottom.Nonmetal oil baffle slide block (11) is slipped into seam groove (13) after by seam groove (13) dimensioned.Step on the oil baffle slide block (11) the qualification radial feeds that match with seam on the seam groove (13), oil baffle slide block (11) is divided into several separation structures such as grade by the circle diameter size, when rotatingshaft (12) was worked, each oil baffle slide block can radially bounce back or radially hold out against under the effect of seam groove (13) bottom spring (9).Oil baffle slide block (9) adopts nonmetallic composite to have necessarily wear-resistant, high temperature resistant and self lubricity.Can not damage its surface with the surperficial comprehensive engagement of rotatingshaft (12).Reach and prevent a large amount of oil leak purposes.At full contact seat ring (2) sidepiece a hermetic seal counter-base circle (7) is installed, is studded with gas-tpe fitting (4) at the top in order to introduce source of the gas.Source of the gas blows out through several inlet holes (6) simultaneously by steam pipe connect (4), and stepless action forms the gas wall in rotatingshaft (12) surface.Reach and prevent micro lubricating oil leakage purpose, have spill port (8) in full contact seat ring (2) bottom and be used for less amount of lubrication oil and be back in the former fuel tank.
Claims (3)
