Abstract
The utility model discloses an axle sleeve sealing device for multistage centrifugal blower, it includes the sealed and axle sleeve seal receptacle of axle sleeve, the axle sleeve seal receptacle is fixed to be set up on the casing, the sealed upper portion of axle sleeve is provided with " 7 " font bellying, leave axle sleeve seal receptacle bottom has down " 7 " style of calligraphy recess, the mandril cover is pasted to the sealed lower part of axle sleeve, the sealed upper portion of axle sleeve is through " 7 " font bellying, " 7 " style of calligraphy recess is connected with the axle sleeve seal receptacle, be clearance fit between the sealed and axle sleeve of axle sleeve, clearance scope control is at 0.25mm -0.3mm. The utility model provides a part that an axle sleeve sealing device for multistage centrifugal blower, non -deformable in the installation can guarantee that the axle sleeve seals up and the installation clearance and the concentricity of axle sleeve, the sealed effect that improves the fan can also reduce its institute and involve to the installation that the axle sleeve is sealed is more convenient with the dismantlement.
Description
Technical field
The utility model belongs to the attached supplementary equipment field of blower, particularly a kind of shaft sleeve sealing device for multistage centrifugal blower.
Background technique
For multistage centrifugal blower, the Main Function of sleeve sealing is: in blower fan course of normal operation, when the gas of suction blower flows in blower runner body at different levels, farthest should avoid the deadweight loss that air-flow produces because sealing is bad at blower interior.Sleeve sealing design accurately can improve the working efficiency of blower fan, reduces wasting of the energy.The sleeve sealing used in the market adopts the design of common concave-convex groove bayonet socket, need to use 2 unnecessary screws fastening shaft sleeve sealing respectively at casing split two ends, installation and removal inconvenience, use in the process of screw fastening, due to production manufacture produce deviation and fitting operation improper, easily cause sleeve sealing roundness deformation, fit up gap can not get the negative consequence such as effective control, concentricity tolerance increase, all directly can have influence on the sealing effect of sleeve sealing.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of shaft sleeve sealing device for multistage centrifugal blower, not yielding in installation process, assemblage gap and the concentricity of sleeve sealing and axle sleeve can be ensured, improve the seal action of blower fan, can also reduce the part that it involves, and the installation and removal of sleeve sealing are more convenient.
For realizing above-mentioned technique effect, the utility model provides a kind of shaft sleeve sealing device for multistage centrifugal blower, it comprises sleeve sealing and sleeve sealing seat, sleeve sealing seat is fixedly installed on casing, sleeve sealing top is provided with " 7 " font lug boss, " 7 " font groove is had down bottom sleeve sealing seat, sleeve sealing bottom is adjacent to axle sleeve, sleeve sealing top is connected with sleeve sealing seat by " 7 " font lug boss, " 7 " font groove, be Spielpassung between sleeve sealing and axle sleeve, interstice coverage controls at 0.25mm-0.3mm.
A kind of shaft sleeve sealing device for multistage centrifugal blower that the utility model proposes, not yielding in installation process, assemblage gap and the concentricity of sleeve sealing and axle sleeve can be ensured, improve the seal action of blower fan, can also reduce the part that it involves, and the installation and removal of sleeve sealing are more convenient.
Accompanying drawing explanation
Fig. 1 is that a kind of shaft sleeve sealing device for multistage centrifugal blower that the utility model proposes arranges structural representation.
Embodiment
See accompanying drawing, a kind of shaft sleeve sealing device for multistage centrifugal blower, it comprises sleeve sealing 4 and sleeve sealing seat 1, sleeve sealing seat is fixedly installed on casing, sleeve sealing top is provided with " 7 " font lug boss, " 7 " font groove is had down bottom sleeve sealing seat, sleeve sealing bottom is adjacent to axle sleeve 2, sleeve sealing top is connected with sleeve sealing seat by " 7 " font lug boss, " 7 " font groove, be Spielpassung between sleeve sealing and axle sleeve, interstice coverage controls at 0.25mm-0.3mm.Main shaft 3 and axle sleeve adopt hot charging excessively to coordinate.
A kind of shaft sleeve sealing device for multistage centrifugal blower that the utility model proposes, not yielding in installation process, assemblage gap and the concentricity of sleeve sealing and axle sleeve can be ensured, improve the seal action of blower fan, can also reduce the part that it involves, and the installation and removal of sleeve sealing are more convenient.
