According to the SSYZ95/95 type twin - screw press, a test device of twin - screw press was designed. The test device was composed of torque test device, axial force test device, radial pressure test device and barrel temperature test device. The test device of twin - screw press was driven by speed regulating motor. The torque meter, loop force - measuring sensor, fluid pressure sensor or strain gauge sensor were used to measure the torque, axial force and radial pressure of the screw press, respectively. The structure of the loop force - measuring sensor, the calibration method of axial prov...
