Description
Technical field
The utility model belongs to air blower sealing device technical field, is related to a kind of Roots Blower Rotor.
Background technique
Roots blower belongs to volume rotary blower, is a kind of typical gas boosting and conveying machinery, maximum
The characteristics of be almost unchanged using capacity in pressure limit, and since its structure is simple, easy to maintenance, long service life,
Mounting means is flexible and changeable, and volumetric efficiency is high, and has the pumped (conveying) medium not characteristics such as oil-containing, thus have been widely used for through
The various industries of Ji construction.
Since there are relative motions between Roots Blower Rotor and shell end face, in order not to interfere or rub, rotor
End face and shell end face between will have gap, referred to as axial gap.If axial gap is too small, when rotor rotates
Axial displacement easily cause shell end face and rotor end-face to wear, while friction generates heat, can make bearing temperature by heat transfer
Degree increases, to damage bearing, influences the normal work of air blower；Axial gap is excessive, then will appear by compressed gas
The phenomenon come is flowed back to via gap portion, causes fan efficiency to reduce, undercapacity.In existing technology, rotor end-face with
Gap design between shell end face is bigger than normal, and internal leakage is big, and fan efficiency is low.
Utility model content
The purpose of the utility model is to provide a kind of Roots Blower Rotors, can effectively reduce rotor end-face and shell ends
Gas leakage between face, improves the reliability of Roots blower.
The utility model is the technical scheme adopted is that a kind of Roots Blower Rotor, the two of Roots Blower Rotor
It is provided with seal groove on a end face, teflon seal item, and teflon seal item are equipped on each seal groove
Side stretch out seal groove outside.
The utility model is also characterized by:
Two groups of seal grooves are provided on each end face of Roots Blower Rotor, on each end face of Roots Blower Rotor
Two groups of seal grooves be symmetrical arranged.
Every group of seal groove is in quadrangle.
One vertex of seal groove is located at Roots Blower Rotor maximum length, other two vertex of seal groove
It is located at positioned at close to the 4th vertex of Roots Blower Rotor maximum width, seal groove close to Roots Blower Rotor and axis
Junction.
The side of teflon seal item is stretched out between the length and Roots Blower Rotor and shell end face of seal groove
Be equidistant.
The utility model has the beneficial effects that
The sealing of full corner lower rotor part axial gap may be implemented in a kind of Roots Blower Rotor of the utility model, and logical
Self-lubricating material sealing strip is crossed, so that the end clearance of Roots blower automatically achieves minimum value after adjustment, it can be effective
The leakage rate for reducing end clearance, reduces its delivery temperature, improves the efficiency and reliability of Roots blower.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of Roots Blower Rotor is provided on two end faces of Roots Blower Rotor 3 as depicted in figs. 1 and 2
Two be in quadrangle seal groove 1, two seal grooves 1 on each end face of Roots Blower Rotor 3 are symmetrical arranged；
One vertex of each seal groove 1 is respectively positioned at 3 maximum length of Roots Blower Rotor；Each seal groove 1
Other two vertex be respectively positioned on close to 3 maximum width of Roots Blower Rotor, 3 maximum width of Roots Blower Rotor
A vertex apart from the seal groove 1 is nearest；4th vertex of each seal groove 1 be located at close to Roots Blower Rotor 3 with
The vertex of shaft connection place, the Roots Blower Rotor 3 and shaft connection place apart from the seal groove 1 is nearest.
Teflon seal item 2 is equipped on each seal groove 1, the side of teflon seal item 2 is stretched out close
Outside sealing groove 1, and length and Roots Blower Rotor 3 and the shell end face of seal groove 1 are stretched out in the side of teflon seal item 2
The distance between it is equal.
A kind of Roots Blower Rotor of the utility model, teflon seal item 2 have self-lubricating and performance resistant to high temperature,
It can prevent from generating direct friction between rotor end-face and shell end face 4, and then protect Roots Blower Rotor 3 and bearing knot
Structure, when Roots blower brings into operation, when rotor is due to vibration or by out-of-balance force generation axial displacement, part is poly-
Tetrafluoroethene sealing strip 2 can be generated with shell end face 4 and be contacted, and after adjustment, teflon seal item 2 can generate part
Abrasion, to guarantee that the gap of teflon seal item 2 and shell end face 4 is minimum at each position, is effectively reduced between end face
The leakage rate of gap improves the efficiency of Roots blower；As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the seal groove of quadrangle design
1 can guarantee effectively to be sealed under a different angle in the end face of Roots Blower Rotor 3, while seal groove 1 does not have
The side of Roots Blower Rotor 3 is extended to, the centrifugal force so as to effectively prevent the rotation of Roots Blower Rotor 3 to generate will
Teflon seal item 2 is thrown away.
Teflon seal item 2 when in use, need to be only mounted on close by a kind of Roots Blower Rotor of the utility model
It can be used in sealing groove 1.
A kind of Roots Blower Rotor of the utility model makes the end face of Roots blower using self-lubricating material sealing strip
Gap automatically achieves minimum value, and the leakage rate of end clearance can be effectively reduced, and improves the efficiency of Roots blower；Can institute
Under angled, rotor axial gap is realized and is sealed；The reflux inside Roots blower is enabled to weaken, to reduce sieve
The delivery temperature of thatch air blower improves the reliability of Roots blower；Small axial movement occurs for Roots Blower Rotor 3
When, teflon seal item 2 can prevent from generating direct friction, Jin Erbao between Roots Blower Rotor 3 and shell end face 4
Protect Roots Blower Rotor 3 and bearing arrangement.
