♦ANSI/ APISPEC 10D-2002 Specification for bow spring casing centralizers;


1 Host Frame

●The mainframe is a double-space door structure. The driving principle is that the motor drives the ball screw pair to rotate after decelerating through the reducer system, thus driving the middle beam up and down to complete the test, the transmission is stable and the noise is low.

●Using four guiding optical screws, φ 40 mm high precision ball screw.The high rigid frame is composed of thick beam and base,which can guarantee the frame with excellent longitudinal and transverse rigidity and good overall accuracy.

●Servo motor drive and reducer system without maintenance, can guarantee the accuracy and stability of the beam ,the speed ratio can reach 1: 100000.

●Under the guidance of the internal control precision of 5% of coaxiality, the cross joint can be precisely aligned in axial test, and the linear motion of the beam can be guaranteed, so as to ensure that the influence of the lateral force on the specimen under load is minimal. Thus, better test performance can be obtained.

2 Controller

●Force , displacement , deformation measurement resolution up to 1 / 300000 of full scale

●AD sampling frequency can be as high as 300 Hz

●Can realize closed-loop control of parameters such as test force,specimen deformation and beam displacement .It can be used to realize the tests of constant speed- test force, constant speed- displacement, constant speed- strain, constant speed-load cycle, constant speed-deformation cycle and so on. Various control modes can be switched smoothly. And smooth transition.Advanced Neuron Adaptive PID Control algorithm.
