The cost-effective brick pressure testing machine (electrohydraulic servo pressure testing machine) is mainly used for the compressive strength test of brick, stone, cement, concrete and other materials, and also for the compressive performance test of other materials. The series of pressure strength testing machine developed by Liangong adopts computer automatic control. The measurement sensors (pressure sensor, displacement sensor, deformation extensometer), servo valve, controller (signal conditioning unit), and servo amplifier form multiple closed loops. realizes the closed-loop control function of the test force, cylinder piston displacement, and deformation of the sample; it has multiple control modes such as constant-rate test force, constant-rate cylinder displacement, and constant-rate strain. And can achieve the smooth switching of the control mode, so that the system has greater flexibility.
The main part of YAW series full-automatic pressure testing machine adopts the oil cylinder underneath, and the oil source part adopts the piano desktop hydraulic oil source. Compared with other brands of pressure testing machines, the outstanding advantages are: the upper platen space adjustment method: electric lifting; the cylinder adopts special technology, honing processing, gap sealing, strong sealing, long service life; high-precision full digital servo valve, imported high pressure oil pump,low noise and stable operation.
