Abstract

According to thermo-elastic deformation theory, take the temperature field analysis results of hydrostatic pressure mechanical seal as volume load to resolve the problem of thermal-structure coupling deformation of rotating and stationary rings in ANSYS software. The distribution laws of thermal strain, thermal stress and thermal-structure coupling deformation are obtained. The effects of working, material and structural parameters on axial, radial thermal deformation and deformation taper of the end faces are discussed in detail, and the main affecting factors are found out. Measures and structural constraint programs to control the thermal deformation are put forward. Base on the theory of thermal deformation compensation, the rotating and stationary rings are optimized, and the thermal deformation before and after their optimization are solved respectively and analyzed comparatively to verify the feasibility of the optimization program. DOI: http://dx.doi.org/10.11591/telkomnika.v11i2.2049

Abstract

  According to the principle of hydromechanics, the flow characteristic of drilling fluid on the screen is studied. In consideration of affecting factors, sieving model equations including kinematic equations and continuity equation for drilling fluid shale shaker are established. This paper shows a novel solution to the sieving model equations by using average energy principle and finite differential method. The computer simulation program of flow capacity of the shaker is developed. The model will be of great significance in evaluating screening performance and screen selection. DOI: http://dx.doi.org/10.11591/telkomnika.v10i6.1399
