Description
Technical field
The utility model relates to a kind of experimental setup of water distributor, particularly a kind of Francis turbine water distributor prepackage servomotor degree of pulling open testing apparatus.
Background technique
The Francis turbine water distributor is being made the test of preassembly in factory and degree of pulling open, and is whether qualified effective way of each parts manufacturing processing of check water distributor.The actual operating state of each parts of simulation water distributor during degree of pulling open, the pulling control ring drives stator and rotates, and checks whether the relation of guide vane opening and servomotor stroke meets design requirement.General normal degree of the pulling open mode of taking has two kinds: a kind of is to use crane, sheave block (namely being commonly called as chain block) degree of pulling open mode; Another kind is tool using servomotor degree of pulling open mode.
Chain block is the conventional method of having used for many years, although chain block mode cost is lower, following deficiency is arranged:
1, chain block one end is fixed on the large earhole of control ring position, and the other end generally is fixed on the platform, for the water distributor system, is External Force Acting during work, affects Systems balanth and Security.
2, chain block behaviour power effect also can adopt crane to replace manpower.Because the characteristics of sheave block are to remedy with sacrifice speed to exert oneself, so this mode efficient is very low, usually being pulled to another stroke from a stroke needs dozens of minutes.
3, because wire rope self has certain regime of elastic deformation, when spurring chain block at the beginning, external force fails to overcome the stiction of system, so that certain resiliently deformable occurs wire rope, even spurring chain block always, control ring does not rotate yet.When external force just can overcome system's stiction, at this moment control ring began to rotate, but kinetic force of friction is less than stiction, and wire rope self begins to shrink rapidly, so control ring can occur suddenly sharply to rotate.This situation is unfavorable for travel point very much, usually also will transfer stroke by means of jack.Will rearrange the installation chain block toward contact when commutating simultaneously degree of pulling open, therefore this degree of the pulling open mode utmost point is not steady, and operation is inconvenience very.
4, chain block is exerted oneself littlely, and the general single maximum of exerting oneself can only reach 10 tons, is only applicable to the test of Pump for Medium and Small Power Generating Set water distributor degree of pulling open.
In addition, tool using servomotor degree of pulling open mode, it is the method for just progressively bringing into use in recent years, the tool using servomotor carries out the test of water distributor prepackage degree of pulling open and generally servomotor is arranged in the control ring inner circle, such as application number be: 200920250279.3 Chinese utility model patent mixed-flow and axial flow hydraulic turbine gate linkage, this arrangement is simple, and the frock expense is low, but it has following several respects shortcoming:
1, the arm of force is little: because the control ring inner circle is little more a lot of than the large earhole distribution circle of control ring diameter, the arm of force that this mode servomotor is exerted oneself is very little, under the condition of same system resistance, to the instrument servomotor exert oneself and bulk strength requires all to want much high.
2, the servomotor stroke is less.Owing to be interior layout, the servomotor physical dimension can not be excessive, just determined that also the servomotor stroke is not too large, for large-scale water distributor, might not satisfy the requirement of degree of pulling open stroke.
3, to go out the angle of force direction and control ring sense of rotation larger for servomotor.Increased on the one hand the requirement of exerting oneself of servomotor, on the other hand might be with the distortion of control ring top.
Because arrangement also is only applicable to Pump for Medium and Small Power Generating Set water distributor prepackage degree of pulling open in the above effects limit, servomotor.
