Design of Pressure Simulation Tester Bearing Cylinder for Borehole Inclinometer Equipment

According to the actual working conditions of drilling in the process of coal mine gas treatment and mine water damage prevention,the main parameters of the bearing cylinder were determined by combining the characteristics of logging and inclinometer equipment and the requirements of the hydraulic test.Through the analysis and research of various sealing forms,the reasonable sealing form and sealing parts were selected,and a set of large diameter bearing cylinder with simple structure,convenient installation and disassembly,low cost and high pressure resistance was designed.The performance of bearing cylinder was verified by engineering applications.The test results show that the designed bearing cylinder completely satisfies the technical conditions of the geophysical logging and clinometers equipment.
