Abstract
The invention discloses a 10 megawatt grade high power waterjetpropulsor impeller balance test fixture, and belongs to the field of a waterjetpropulsor test fixture. The fixture includes a main shaft, a stopping ring, a cone sleeve, a sleeve and a rotary shaft. Through arrangement of the cone sleeve on the main shaft, an installation hole of an impeller matches an outer wall of the cone sleeve. The cone sleeve and the impeller are fastened so that the impeller is installed on the main shaft. Two ends of the cone sleeve are axially positioned by using a shaft shoulder and the sleeve, and thus the impeller is axially positioned. The cone sleeve is circumferentially positioned through keys, and thus the impeller is circumferentially positioned. Through arrangement of a third flange on the sleeve, the sleeve and one end face of the main shaft are fixed by the third flange. Because a gap may be reserved between the third flange and the one end face of the main shaft, the sleeve can still press an end face of the impeller after impeller to be tested is exchanged, and the impeller is axially positioned.
Description
Technical field
The present invention relates to water jetsystem test frock field, in particular to a kind of 10 megawatt-grade high-power water jetsystem impeller balance test frocks.
Background technology
Water jetsystem is a kind of novel ship's power plant, the reactive force that the thrust of water jetsystem is the current sprayed by propulsion pump obtains, and is realized the manipulation of boats and ships by control vane and the distribution of falling Rudder and Steering Gear and the direction that changes current jet flow.
The core texture of water jetsystem is impeller, operationally, impeller is in high speed rotating state, if there is the situation of mass unbalance in the fabrication process in impeller, then in the process of high speed rotating, whole water jetsystem can be made to produce bigger vibrations, the situation that water jetsystem is damaged even occurs, especially in large-scale water jetsystem, the high-power water jetsystem of such as 10 MW class, the quality of impeller is very big, at about 1200 kilograms, if there is unbalanced defect in the fabrication process and be applied directly on hull in impeller, hull is then likely caused to damage, jeopardize the life security of personnel on ship, therefore the impeller of water jetsystem must carry out balancing test after finalization of the manufacture.
The balancing test of impeller be generally by impeller location and installation on the main shaft of balancing test frock, then turned round by power set. After impeller is arranged on main shaft, it is necessary to carry out circumference location and axial location, at least there is following problem in just existing water jetsystem impeller balance test frock:
1, because the internal surface of the open holes of common impeller is cylindrical surface, so the outside surface of main shaft is also cylindrical surface, and the internal surface of the open holes of high-power water jetsystem impeller is cone surface, therefore by general main shaft, high-power water jetsystem impeller cannot be installed.
2, after impeller is arranged on main shaft, one end is by after the shaft shoulder or other structural orientation, the other end is located by sleeve, and the fixing screw being perpendicular to main shaft cylinder side wall that normally arranges on sleeve of sleeve, fixed by screw, it is thus desirable to corresponding position arranges the screw being perpendicular to cylinder side wall on main shaft, this just makes the processing error due to impeller, after changing impeller to be tested, sleeve may be caused cannot to push down the end face of impeller, or sleeve push down impeller end face after screw on sleeve cannot align with the screw on main shaft, this either way can make impeller cannot complete axial location, and the way that each impeller customizes a main shaft considerably increases the cost of test.
