Abstract
The invention provides a detecting device for liquid flow of a hollow turbine blade of a combustion gas turbine, relates to the detecting device for blade liquid flow, and belongs to the field of mechanical assembling detection. The problem of the present detecting device that accurate and reliable technical data cannot be obtained by detecting due to leaky sealing, unstable clamping and complex operation is solved. A left supporting base and a right supporting base are arranged on a base; a pair of guide rails is arranged between the left supporting base and the right supporting base; a pressing plate is arranged on the pair of guide rails and is in sliding connection with the pair of guide rails; a stepped through hole is formed on a side wall of the left supporting base; one end of a straight tube connector is communicated with the stepped through hole; a cover plate is arranged on an inner side wall of the left supporting base; the cover plate and the left supporting base are in detachable connection; a first through hole which is communicated with the stepped through hole is formed on the cover plate; at least one positioning bulge is arranged on the inner side wall of the cover plate; an aligning sleeve is arranged on an outer side wall of the pressing plate; the aligning sleeve and the pressing plate are integrally manufactured; and a jacking bolt passes through the side wall of the right supporting base and is arranged corresponding to a positioning sleeve of the pressing plate. The detecting device provided by the invention is used for detecting the liquid flow ofthe hollow turbine blade of the combustion gas turbine.
Description
technical field [0001] The invention relates to a blade liquid flow detection device, which belongs to the field of mechanical assembly detection. Background technique [0002] The hollow turbine blades of gas turbines work under high temperature and high pressure conditions. When the blade hollow cavity is working, there is cooling flow. The purpose is to reduce the high temperature at the outlet of the combustion chamber and prevent the gas from burning the turbine blades. Therefore, it is necessary to conduct a liquid flow detection test for the relevant hollow turbine blades to check whether the inner cavity of the hollow turbine blades can meet the design technical requirements. However, the existing detection device adopts a fixed clamping method, which has a single structure and many defects in use, such as poor sealing, unstable clamping, complicated operation, etc., so that accurate and reliable technical data cannot be obtained for detection, and errors larger. ...
