Abstract
The utility model belongs to the technical field of blowers, and relates to a plate welding type blower casing shaft end zero-leakage sealing connector which comprises a bearing box, a standard seal group, a blower body, a coupler and a motor, wherein the motor is connected with the bearing box through the coupler, the plate welding type blower casing shaft end zero-leakage sealing connector is characterized in that flexible connectors are arranged at the two end shafts of the shaft of the blower body, the flexible connectors are positioned between the casing and the standard seal group, a sealing and supporting device is arranged below the standard seal group, the standard seal group is connected with the bearing box, a sealing and fixing sleeve is arranged on the outer side of the standard seal group, and the standard seal group is fixed on the bear box by the sealing and fixing sleeve through bolts. The plate welding type blower casing shaft end zero-leakage sealing connector has the advantages of reasonable design, simple structure, low cost and reliability in performance, can be used for well adjusting the concentricity after flexible connection, and enables a blower to achieve zero leakage after assembling.
Description
Technical field
The utility model relates to blower fan technical field, and specifically a kind of plate weldering formula fan casing axle head zero leakage is tightly connected.
Background technique
Blower fan is that China is called for short the custom of gas compression and gas conveying machinery.Usually said blower fan comprises ventilator, blower, compressor and Roots blower, and blower fan is divided into turbine-type and positive displacement by working principle, and that turbine-type is subdivided into is again centrifugal, axial flow, mixed-flow.When centrifugal fan and blower can be used for special gas conveying, axle head needs strict sealing.As being widely used in the conveying of natural gas, coal gas, chemical gases, its casing generally adopts ironcasting, plate weldering formula, glass die, engineering plastic type.Along with the development trend of the separate unit of equipment, standardization, maximization, plate weldering formula casing has become one of main flow.Tradition axle head zero leakage seal fan, standard seal are directly fixed on the both sides end face of the casing that machining is good, because plate welding machine shell is subject to distortion, machining Accuracy, although standard seal can guarantee zero leakage, but during assembling, can not guarantee the required precision of concentricity, planeness, cause rear leakage of blower fan assembling to exceed standard.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, provides a kind of reasonable in design, simple in structure, and the plate weldering formula fan casing axle head zero leakage of reliable performance is tightly connected.
The technological scheme that the utility model adopts is: the zero leakage of a kind of plate weldering formula fan casing axle head is tightly connected, comprise bearing housing, standard seal group, blower fan body, coupling, motor, motor is connected with bearing housing by coupling, the two end axles that it is characterized in that blower fan body is provided with soft joint sleeve, soft joint sleeve is between casing and standard seal group, standard seal group has sealing support device, and standard seal group is connected with bearing housing.
Described soft joint sleeve, between casing and standard seal group, also can be provided with sealing fixed cover in standard seal group outside, and standard seal group is fixed by bolts on bearing housing by sealing fixed cover.
The utlity model has reasonable in design, simple in structurely, cost is low, reliable performance, and long service life installs soft connection additional between casing and standard seal group, because soft connection can better be adjusted concentricity, makes the blower fan after assembling reach zero leakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is another structural representation of the present utility model.
Mark in figure: 1, bearing housing, 2, standard seal group, 3, sealing support device, 4, soft joint sleeve, 5, blower fan body, 6, coupling, 7, motor, 8, sealing fixed cover.
Embodiment
As seen from Figure 1, Figure 2, the zero leakage of a kind of plate weldering formula fan casing axle head is tightly connected, comprise bearing housing 1, standard seal group 2, blower fan body 5, coupling 6, motor 7, motor 7 is connected with bearing housing 1 by coupling 6, in the two end axles of blower fan body 5, be provided with soft joint sleeve 4, soft joint sleeve 4 is between casing and standard seal group 2, and standard seal group 2 has sealing support device 3, and standard seal group 2 is connected with bearing housing.
Also can be soft joint sleeve 4 between casing and standard seal group 2, in standard seal group 2 outsides, be provided with sealing fixed cover 8, standard seal group 2 by sealing fixed cover 8 be fixed by bolts on bearing housing.
Between fan casing two ends and standard seal, by soft joint sleeve, be connected and fixed, when blower fan body 5 is main equipment, standard seal group 2 is arranged on the sealing support device 3 with self-align supporting, and standard seal group 2 is connected with bearing housing; When blower fan body 5 is mini-plant, in the standard seal group outside of blower fan body shaft, there is sealing fixed cover 8, standard seal group 2 is fixed by bolts on bearing housing by sealing fixed cover 8.Because soft joint sleeve can be adjusted concentricity, make the blower fan after assembling reach zero leakage.The utility model is reasonable in design, simple in structure, cost is low, reliable performance.
Claims (2)
