The carbon ring sealing structure comprises a connecting flange and a sealing plate, an intermediate sleeve is arranged between the connecting flange and the sealing plate, three groups of carbon rings are arranged in the intermediate sleeve, and a spring support ring is arranged between two adjacent groups of carbon rings. The utility model has the advantages of excellent sealing performance, good stability, corrosion resistance, capability of effectively prolonging the service life of the fan, and low cost.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly a kind of carbocyclic ring sealing configuration that is used for Blower Housing and main shaft joint.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Blower fan is the custom abbreviation of China to gas compression and gas conveying machinery, and usually said blower fan comprises ventilator, blower, and compressor and Roots blower, but do not comprise piston compressor isometric(al) formula blower and compressor.Gas compression and gas conveying machinery are that a mechanical switch of rotation is gas pressure energy and kinetic energy, and gas delivery is gone out.
Blower fan can quicken air flows, can discharge gas fast, is applicable to multiple occasion, as ventilation, dust discharge and the cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building.If the gas that blower fan is discharged is poisonous or has corrosively that then most of blower fans all can be subjected to strict restriction, have only the blower fan of favorable sealing property just can use.At present, have the blower fan of sealability, sealing effect is relatively poor mostly, and corrosion resistance is relatively poor, and working life is shorter, and cost of production is higher.
The model utility content
The purpose of this utility model provides a kind of carbocyclic ring sealing configuration that is used for Blower Housing and main shaft joint, can solve effectively that the sealing effect that prior art exists is poor, corrosion-resistant, working life problem such as weak point, cost of production height.The utility model relates to a kind of carbocyclic ring sealing configuration that is used for Blower Housing and main shaft joint, comprise adpting flange and sealing plate, be provided with middle cover between described adpting flange and the sealing plate, be provided with three groups of carbocyclic rings in the described middle cover, be provided with the spring support ring between two groups of adjacent carbocyclic rings.The joint of described adpting flange and middle cover is provided with O-ring seal.Described sealing plate is provided with O-ring seal with the joint of middle cover.Joint between two adjacent carbocyclic rings is provided with locating stud, and adjacent carbocyclic ring and the joint between the adpting flange are provided with locating stud, and adjacent carbocyclic ring and the joint between the sealing plate are provided with locating stud.Be respectively equipped with identical, the corresponding screw in position of size on described adpting flange, middle cover and the sealing plate, be provided with group leader's bolt in the screw.Be provided with three graphite annuluss that fasten as one with extension spring in every group of carbocyclic ring, every group of carbocyclic ring size is identical, and the cavity size in the carbocyclic ring is identical.Be provided with two or more springs in the described spring support ring, described spring horizontal is placed.Described adpting flange is provided with two or more screws, is provided with clamping bolt in each screw.Advantage of the present utility model is: favorable sealing property, and good stability, corrosion-resistant, effectively prolonged working life of blower fan, cost is lower.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described.
Embodiment
The utility model relates to a kind of carbocyclic ring sealing configuration that is used for Blower Housing and main shaft joint among the figure, comprise adpting flange 1 and sealing plate 2, be provided with middle cover 3 between described adpting flange 1 and the sealing plate 2, be provided with three groups of carbocyclic rings 4 in the described middle cover 3, be provided with spring support ring 5 between two groups of adjacent carbocyclic rings 4.
Described adpting flange 1 is provided with O-ring seal 6 with the joint of middle cover 3, and the joint of described sealing plate 2 and middle cover 3 is provided with 7, two O-ring seals of O-ring seal and is made by the rubber of good springiness, can further strengthen sealing effect.
Joint between two adjacent carbocyclic rings is provided with locating stud 8, and adjacent carbocyclic ring and the joint between the adpting flange are provided with locating stud 9, and adjacent carbocyclic ring and the joint between the sealing plate are provided with locating stud 10, and be easy to install.Be respectively equipped with identical, the corresponding screw in position of size on described adpting flange 1, middle cover 3 and the sealing plate 2, be provided with group leader's bolt 11 in the screw.
Be respectively equipped with identical, the corresponding screw in position of size on described adpting flange, middle cover and the sealing plate, be provided with group leader's bolt in the screw, adpting flange, three parts of middle cover and sealing plate are in the same place by same group leader's bolt.Described adpting flange is provided with two or more screws, is provided with one group of clamping bolt 12 in each screw.
Before blower fan work, the utility model is installed on the blower fan, the middle cover carbocyclic ring of respectively organizing partly is enclosed within on the blower fan main shaft, adpting flange is fixed on the housing of blower fan, the bolt of respectively organizing of adpting flange is tightened.Be provided with three graphite annuluss that fasten as one with extension spring 13 in every group of carbocyclic ring, extension spring can be enclosed three graphite annuluss, and graphite annulus is pressed on the blower fan main shaft 14, prevents that blower fan main shaft from gas leakage radially taking place.Every group of carbocyclic ring size is identical, and the cavity size in the carbocyclic ring is identical, easy to install.Be provided with two or more springs in the described spring support ring, described spring horizontal is placed spring can guarantee that each carbocyclic ring clamps each other, makes the end face of respectively organizing between the carbocyclic ring can not leak gas.
