Abstract: A coaxial capacitive sensor includes a sensor lubricating oil inlet and a sensor lubricating oil outlet. The sensor lubricating oil inlet and the sensor lubricating oil outlet separately communicate with the interior of the coaxial capacitive sensor. The interior of the coaxial capacitive sensor is provided with a center bearing, electrode support insulating substrates, and electrode plates. The plurality of electrode support insulating substrates and the center bearing divide the interior of the coaxial capacitive sensor into a plurality of detection sub-spaces, and the electrode plates are attached onto the electrode support insulating substrates, respectively. The coaxial capacitive sensor provided by the present invention can be arranged in a lubricating oil pipeline to avoid the influences of environmental factors on the testing results, and can on-line detect the characteristics of the lubricating oil abrasive particles efficiently.

Abstract: A method for accurately producing the drilled hole in a wall of a component fabricated by investment casting process, such as for use in a blade or steam turbine includes the following steps. The 3D data of actual component is obtained from the measurements or from the numerical simulation. The actual model and the ideal model are aligned and compared, a series of cutting planes are given to establish a series of 2D cross-sections of the actual and ideal models after registration. Each cross-section is dispersed into discrete points, the distance between each corresponding points are calculated and formed into 2D displacement. The accurate parametric model consisting of the depth, hole center, and the nominal vector is obtained on the basis of considering the deviations in geometrical and positional values. The drilled hole is then produced according to the corrected parametric drilled-hole geometrical and positional value.
