Description Schemes:


  1.1. The main machine

  1. The main machine adopts underneath type of oil cylinder, tensile space is above the main machine, compression and bending space is between the lower cross beam and working station.
  2. Solid four-standard column and two-lead screw structure design, so the whole machine has strong stability.
  3. Movable cross-beam is designed with unique clearance elimination mechanism, avoiding test error caused by cross-beam stress of B type machine.
  4. There designs a sliding plate of 10mm between jaw and jaw splint, effectively extending service life of jaw splint.
  5. Test space can be divided into three segments for adjustment according to length of specimen, the highest point is suitable for the use of peripheral equipment like high temperature furnace.

   1.2. Drive system


   Lower cross beam lifting adopts hydraulic motor, chain, and lead screw pair drive to realize adjustment of tensile and compression space.

   No matter in the state of adjusting space or in the test process, it both reaches operation if zero clearance.


    1.3. Hydraulic system (table-type oil source)


       Hydraulic principle:


As shown in figure 2, it is load-adaptive meter in speed control system.


Hydraulic oil in the fuel tank enters into oil circuit when the motor drives the high-pressure gear pump, it flows through non-return valve, 10μhigh-pressure filter, differential pressure valve group and servo valve to enter into oil cylinder. The computer sends out signal to the servo motor, to control the mouth and direction of servo valve, so as to control the flow entering into the oil cylinder, realizing control of uniform-speed test force and displacement.
