FUNCTIONAL FEATURES--COMPUTER CONTROL HYDRAULIC TENSILE TESTER 

Hydraulic System--COMPUTER CONTROL HYDRAULIC TENSILE TESTER 

the hydraulic fluid, in hydraulic fluid container being forced into fluid pipe by performing of motor to drive the high pressure pump,
Flows and passes through one-way valve, high pressure oil filter, differential valve assembly, servo valve and into hydraulic cylinder.
the computer will send control signal to servo valve to control the open and direction of servo valve, which will control the flow
Quantity of hydraulic fluid into hydraulic cylinder so as to achieve constant velocity testing force as well as displacement control.
