Hydraulic Universal Testing Machine

Hydraulic Universal Testing Machine

• Working cylinder-piston adopts gap seal, with small frictional force;
• The oil pump has low noise, stable performance and long service life;
• Independent hydraulic chuck oil source and the chucking force can be adjusted;
• Proportional servo valve with quick action response and the demand for the oil quality is low;
• The performance of the sensor is stable with high accuracy;
• The resolving capability is high without grading in the whole measurement range;
• Having the functions of automatic zero setting, automatic calibration, automatic diagnosis and automatic storage, etc.
• The automatic control of constant test force, constant deformation, constant displacement, even rate of stressing and even rate of strain is realized and impact free switch-over is realized in the test;
• Having protection functions for over current, over speed, over-test force and over stroke, etc.
