Abstract
The utility model relates to a gas sealing device and specifically relates to a framework sealing assembly which is arranged at a shaft end of a Roots blower. The framework sealing assembly comprises a framework oil seal, a lining ring, a sealing shaft sleeve, a sealing ring and a sealing base. The framework sealing assembly is characterized in that the sealing ring and the framework oil seal are sleeved on the outer diameter of the sealing shaft sleeve; one lining ring is arranged in the framework oil seal; the sealing base is arranged outside the framework oil seal and the sealing ring; the sealing base is provided with a pressure cover at a gas flow outlet end, and the pressure cover is fixed on the sealing base by a fastening bolt; the sealing shaft sleeve is provided with a groove inside the gas flow outlet end; an O-shaped sealing ring is arranged on the groove; all elements are arranged in the sealing base to form a sealed assembly which is lubricated by grease in the middle. The sealing assembly disclosed by the utility model is simple in structural design, good in sealing property and capable of effectively solving a gas medium leakage problem of the Roots blower.
Description
Technical field
The utility model relates to gas-tight sealing, particularly a kind of reinforced seal assembly that is arranged on the Roots blower axle head.
Background technique
At mechanical field, gas-tight sealing is very important parts always, be directly connected to workmanship and the working life of a machine, leaktight encapsulation commonly used is equipped with: dry gas seals has appearred again in labyrinth seal, piston ring sealing, air extracting seal, reinforced seal, mechanical seal etc. in recent years.Wherein reinforced seal is because of simple in structure, low price, good sealing effect are widely used, because reinforced seal belongs to the contact sealing, the problems such as lip wearing and tearing often occur, cause assembling the situations such as bad, seal leakage, wearing and tearing axle and occur, especially be arranged on the black box of Roots blower axle head.
The model utility content
The purpose of this utility model is some problems for above-mentioned existence, provides a kind of simple in structure, and the reinforced seal assembly of good sealing effect effectively solves the problem that the Roots blower medium is revealed.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of reinforced seal assembly, comprise outside framework oil seal, lining ring, sealing axle sleeve, seal ring, sealing seat, it is characterized in that, described sealing axle sleeve external diameter cover has seal ring and outside framework oil seal, and a lining ring is set between outside framework oil seal, and outside framework oil seal and the seal ring outside are equipped with sealing seat, sealing seat is provided with gland at airflow outlet end, and be fixed on sealing seat by fastening screw trip bolt, sealing axle sleeve is provided with a groove in the airflow outlet end inboard, an O RunddichtringO is installed on groove.
Outside framework oil seal of the present utility model arranges 2-3.
Seal ring of the present utility model arranges 2-3.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
A kind of reinforced seal assembly of the present utility model, simple in structure, assembling and easy to maintenance, sealing effect is good, has effectively reduced the problem of Roots blower gas leakage, has increased the working life of equipment.
The accompanying drawing explanation
Fig. 1 is that master of the present utility model looks sectional view.
Fig. 2 is the A section enlarged view of Fig. 1.
Mark in figure: 1-O RunddichtringO, 2-outside framework oil seal, 3-lining ring, 4-sealing seat, 5-seal ring, 6-sealing axle sleeve, 7-fastening screw trip bolt, 8-gland.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, Fig. 2, a kind of reinforced seal assembly, it is characterized in that, comprise gland 8, outside framework oil seal 2, lining ring 3, sealing axle sleeve 6, seal ring 5, sealing seat 4, fastening screw trip bolt 7, sealing axle sleeve 6 external diameters set gradually outside framework oil seal 2, lining ring 3, seal ring 5, then overlap upper seal support 4, airflow outlet end covers gland 8, fixing with fastening screw trip bolt 7, sealing axle sleeve 6 is opened a groove at airflow outlet end, and an O RunddichtringO 1 is installed on groove.And on processing technology, sealing axle sleeve 6 is carried out to special processing, improve its wear resistance and touch the sealing at position with being coupling; At fit on, outside framework oil seal and associated part are carried out to special processing.Outside framework oil seal 2 arranges 2-3, and seal ring 5 arranges 2-3.Outside framework oil seal 2 and O RunddichtringO 1 material are fluorine rubber, and seal ring 5 materials are polytetrafluoroethylene+polyphenyl fat.All element is contained in a sealing seat 4, becomes a sealing group, and centre has grease lubricious.
Black box of the present utility model belongs to direct contact seal, easily causes the wearing and tearing of axle.For avoiding the wearing and tearing of axle, adopt and add sealing axle sleeve 6 methods on axle, lip directly be coupling tactilely, but contact with sealing axle sleeve 6.Sealing axle sleeve 6 materials are gray cast iron, on processing technology, sealing axle sleeve 6 are carried out to special processing, improve its wear resistance and touch the sealing at position with being coupling; At fit on, outside framework oil seal 2 and associated part are carried out to special processing, guarantee the reliability of sealing and reach good sealing effect.
