Abstract
The utility model discloses a device for testing dynamic balance of a single-shaft dual-stage impeller. The device comprises a balance shaft and a spacing sleeve; the balance shaft is provided with two impeller installation structures; the impeller installation structure comprises a keyway and a key end matched with the keyway respectively; and the spacing sleeve is arranged at a position in which the spacing sleeve is parallel to the balance shaft. By adopting the scheme, the balance shaft is provided with two impeller installation structures by which the two-stage impeller (two impellers need to correct the balance) is arranged. The spacing sleeve is arranged between a first stage impeller and a second stage impeller after the first stage impeller is installed on the balance shaft. The spacing sleeve positions the axial direction of the two-stage impeller as the same position at which the impeller is practically installed on the motor. During the balance correcting process, the practical situation that the impeller of a wind turbine is arranged on the motor is simulated, the running of the two-stage impeller on the motor is tested more accurately, and the balance precision problem of a whole wind turbine after practical installation is solved.
Description
Technical field
The utility model relates to a kind of single shaft twin-stage impeller dynamic balance check device, be applicable to the dynamic balance calibration of single shaft couple-stage axial-flow fans, belong to blower fan and ventilating engineering technical field.
Background technique
Development trend according to present domestic various ventilating engineerings has proposed the requirement of high pressure and compact structure to ventilation system.Along with the appearance of single shaft, single action power couple-stage axial-flow fans, its dynamically balanced correction becomes a new problem, only takes effective measures the balance quality that could guarantee coaxial twin-stage impeller system, could ensure that the engineering ventilation system normally moves.
Have now single shaft, the single impeller of the general employing of single action power couple-stage axial-flow fans are proofreaied and correct dynamic balancing respectively, though can guarantee two balance qualities that impeller is single like this, but because two impellers are mounted on the same main shaft and certain spacing are axially being arranged, so the balance quality of the whole blower fan after the as installed is not high.
The model utility content
At above-mentioned situation, the problem that the utility model quasi-solution is determined provides a kind of single shaft, single action power twin-stage impeller dynamic balance check device, to satisfy the balance quality requirement of the whole blower fan after the as installed.
For achieving the above object, the utility model is by the following technical solutions: a kind of single shaft twin-stage impeller dynamic balance check device, it comprises trunnion shaft and spacing sleeve, described trunnion shaft is provided with two impeller installings, described impeller installing comprises the keyway and the key tip that is complementary with described keyway respectively, and described spacing sleeve is at the trunnion shaft parallel position.
As improvement, described spacing sleeve comprises the simplified and telescopic rod of cover, and described telescopic rod is scalable to be fixed in the sleeve body, and described telescopic rod is provided with scale.
Adopt such scheme,, both stage impellers can be installed for needing to proofread and correct two impellers of balance because described trunnion shaft is provided with two impeller installings.Described spacing sleeve is after first order impeller is installed on the trunnion shaft, is installed between first order impeller and the second level impeller.Described spacing sleeve becomes the axially locating of both stage impellers and impeller as installed identical position on motor.In the process of balance correction, simulated draught fan impeller and be installed in actual conditions on the motor.More accurate effect the running of both stage impellers on motor, solved the balance quality problem of the whole blower fan after the as installed.
Description of drawings
Fig. 1 is the structural representation of the utility model single shaft twin-stage impeller dynamic balance check device;
Fig. 2 shows it is the structural representation of spacing sleeve.
Among the figure: 1-trunnion shaft, 2-spacing sleeve, 3-keyway, the 4-key tip, 5-sleeve body, 6-telescopic rod, 7-scale (7), 8-impeller.
Embodiment
As shown in Figure 1, single shaft twin-stage impeller dynamic balance check device of the present utility model is drawn together trunnion shaft 1 and spacing sleeve 2, described trunnion shaft 1 is provided with two impeller installings, described impeller installing comprises the keyway 3 and the key tip 4 that is complementary with described keyway 3 respectively, and described spacing sleeve 2 is at trunnion shaft 1 parallel position.
Described spacing sleeve 2 after first order impeller 8 is installed on the trunnion shaft, is installed between first order impeller and the second level impeller 8, and the axially locating of both stage impellers 8 is become and impeller as installed identical position on motor.Behind the location, during the impeller dynamic balance check, spacing sleeve 2 is dismountable.
Described both stage impellers is two identical or different axial flows, mixed flow or diagonal impellers.Described trunnion shaft is the special equilibrium axle with two keyways and impeller mounting point.Described spacing sleeve is to be the location flat key of connection trunnion shaft and bilobed wheel at described pair of key.
Referring to Fig. 2, as improvement, described spacing sleeve 2 comprises sleeve body 5 and telescopic rod 6, described telescopic rod 6 scalable being fixed in the sleeve body 5, and described telescopic rod 6 is provided with scale 7.Can make spacing sleeve 2 satisfy the dynamic balance check needs of different spacing impeller like this.
