Lab Testing Equipment Automatic Pressure Testing Machine With High Precision Digital Servo Valve

Automatic Pressure Testing Machine With High Precision Digital Servo Valve

Product introduction

The measurement and control system adopts high precision digital servo valve, with force closed-loop control function, can achieve equal load rate loading or equal stress rate loading, high control accuracy, good reliability, the use of micro-computer to achieve electronic measurement, automatic compressive strength test, automatic calculation and printing reports, widely used in construction industry and testing units.

Hydraulic System

Hydraulic oil in the tank through the motor driven high-pressure pump into the circuit, through the one-way valve, high-pressure oil filter, pressure differential valve group, servo valve, into the cylinder. The computer sends out the control signal to the servo valve, controls the opening and direction of the servo valve, thus controlling the flow of the oil cylinder and realizing the control of the Isokinetic test force.

Force measuring system

The use of high-precision amplifiers and A/D converter, the whole process, real-time display load, peak, load speed and strength;l

PID closed-loop control strategy to achieve constant-speed loading, real-time display load curvel

Automatic interval timing and continuous test;

Inquiry, printing test results flexible and convenient;

Safety Protection Device

When the test force exceeds the maximum test force of 3%, overload protection, pump motor shutdown.
