3 Detailed description
Hydraulic system
Through the high pressure pump driven by the motor, the hydraulic oil in the oil tank is driven into the oil path, through the one-way valve, the high pressure oil filter, the pressure difference valve group and the servo valve entry cylinder.The computer sends out the control signal to the servo valve, controls the opening and direction of the servo valve, thus controls the flow rate of the oil entering cylinder, and realizes the control of constant velocity test force.
Force measuring system
1. High precision amplifier and A/D converter, not divided into files in the whole process, real-time display load, peak load speed and strength;
2. PID closed loop control strategy to achieve constant speed loading, real-time display loading curve
3. Automatic interval timing and continuous testing
4. Query, print test results flexible and convenient
Safety protection device
When the test force exceeds 3% of the maximum test force , overload protection, pump motor stop.
