I  Introduction YAW-2000-type machine is mainly used for the test brick, stone, cement, concrete and other materials’ compressive strength  and compressive properties test.

program description 1  host

2 Spatial adjustment method  Electric lift 3 Hydraulic system Hydraulic oil tank high pressure pump driven by the motor into the circuit, flows through the check valve, high pressure filter, pressure valve, servo valve, into the cylinder. Computer control signals to the servo valve, the control and direction of the servo valve opening to control the flow into the cylinder to achieve constant test force control. 4 control system System, including digital servo valve, high-precision sensors, controllers and software, high control precision and reliability. Meet the GB, ISO, ASTM and other standards on cement, mortar, concrete and other materials testing requirements. System has the following features: Closed-loop control with force; Loading rate to achieve such load or other stress rate loading; The use of computer realization of electronic measurement, automated test; Computer automatically calculates the results and print reports.

5 safety devices When the test force exceeds the maximum test force of 3%, the overload protection, oil pump motor stops.
