Definitions
- the invention relates to a device and a method for expelling from positively held on a wheel disc blades, in particular compressor blades.
- Ver Whyrradscale compressor blades are subject to wear, which is why they must be replaced after certain delay intervals in a revision.
- the Ver Whyrradrisen be first removed from the turbine, whereupon the compressor blades are usually removed locally and replaced by new compressor blades.
- the compressor blades are held in a form-fitting manner via a dovetail-shaped blade root in correspondingly shaped grooves formed on the compressor wheel disk. Securing a compressor blade against axial displacement in the corresponding groove is realized either via locking plates or on the impressing of two formed on the blade root securing lugs at the ends of the respective groove.
- the release of the compressor blades from the Verêtrradility in the context of the revision of a gas or steam turbine is done so far by manual expulsion.
- the removed Verêtrradfusionn are first placed horizontally with the hub on a base. Then two workers each drive the blades one after the other with the help of a copper bolt and corresponding hammer blows.
- a worker encloses the copper studs, which are usually wrapped in rags, and places them on the blade root.
- the second worker hits the copper bolt with a 5 or 10 kg sledgehammer.
- the physical stress of the workers and the risk of injury is high.
- the Ver emphasizerradility can be easily damaged during manual expulsion. If the blades can not be driven out with this method, the blades are sawn off behind the blade root. Then a relief groove must be milled from the outside into each blade root of the compressor wheel disk with a side-milling cutter in order to be able to drive out the blades afterwards.
- the present invention provides an expelling device for expelling paddles held in a form-locking manner on a wheel disc, comprising a base frame, a frame attached to the base frame, a turntable arranged on the base frame, in particular a lifting turntable a striking unit fixed to the frame, comprising an ejection punch and a striking mechanism acting thereon, a clamping unit provided pivotally on the frame and adapted to support the wheel disc during the ejection of a blade, and a cutting unit arranged separately and spaced from the frame.
- the wheel disc on which the blades to be driven are held can be mounted on the turntable accordingly.
- the milling unit can then embossing areas, with which the blades to be driven are fixed to the wheel disc, be removed before the expulsion process, at least for the most part.
- grooves can be introduced with the milling unit prior to performing the Austreibereaes in the blade roots of the blades to be driven, which serve to receive and Abstützung the Austreibestkovs.
- the shape of the groove preferably corresponds substantially to the shape of the punch.
- Such grooves can prevent accidental slipping of the ejection punch from the blade to be driven out.
- the individual blades can then be driven out semi-automatically or fully automatically with the Austreibest Zi the beater unit and acting on this percussion.
- the clamping unit serves during the expulsion of the blades primarily to neutralize the resulting reaction forces to prevent slippage of the Verêtrradility during the expulsion.
- the expulsion device according to the invention the body of the worker performing the removal of the blades is hardly or not at all stressed. Also, the risk of accidents compared to manual expulsion is much lower. In addition, a very high process quality is achieved, whereby at the risk of damage to the Verêtrradsay is minimal. Furthermore, it is unlikely that sawing the blades behind the blade root or milling the blade root is required. Furthermore, the time and expense for the expulsion of blades using the expulsion device according to the invention is very low, which is associated with low downtime and failure costs of the turbine in the context of a revision.
