Lr-Yes-3000d Digital Display High Strength 3000kn Press Tester Hydraulic Testing Machine

Product Description

LR-YES-3000D Digital Display High Strength 3000KN Press Tester Hydraulic testing machine
1.Introduction
Measurement and control system with high precision digital servo valve, have force closed-loop control function, can achieve load rate such as load or stress rate loading, such as high control precision, good reliability, electronic measurement is realized by using microcomputer, completion compressive strength test, the automatic calculation and print reports, widely used in the construction industry and testing units.

2. Hydraulic system
The hydraulic oil in the tank pumps the high-pressure pump into the oil circuit through the motor, which flows through the one-way valve, the high pressure filter, the differential valve group, and the servo valve, and enters the cylinder.The computer sends out the control signal to the servo valve, controls the opening and direction of the servo valve, and thus controls the flow into the cylinder, and achieves the control of the iso-velocity test force.
