1、 Introduction

The main engine is a two column, two screw, and oil cylinder bottom mounted type. The stretching space is located above the main engine, and the compression and bending test space is located between the lower crossbeam and the workbench of the main engine. The force measuring instrument adopts a high-definition LCD display screen, making experimental data convenient and intuitive.

Our company is the drafting unit participating in the evaluation outline of the national testing machine form for this series of products

2、 Transmission system

The lower crossbeam is lifted and lowered using a motor driven by a reducer, chain drive mechanism, and screw pair to achieve adjustment of stretching and compressing space.

3、 Hydraulic system

The hydraulic oil in the oil tank is driven by a motor to enter the high-pressure pump into the oil circuit, flows through the high-pressure oil filter, returns to the oil valve, and enters the oil cylinder. The force measuring instrument collects and analyzes data through sensors, displays the hourly force value, and the tester controls the flow rate through the oil delivery valve to achieve the speed of the test force.

4、 Force measuring system

Support tensile, compressive, shear, bending and other tests;

Manually adjust the return oil valve for simple and flexible operation;

Support customization of experimental parameters;

Electronic force measurement, LCD display of test force time curve, test force, test force peak, and yield force of materials with obvious yield characteristics;

Flexibility and convenience in querying test results;

Equipped with a micro printer.

5、 Description of force measuring instruments

(1) Home screen

(2) Experiment/Query

6、 Safety protection device

When the test force exceeds 3% of the maximum test force, the overload protection and oil pump motor stop.

When the piston reaches the upper limit position, the limit protection stops and the oil pump motor stops.

When the crossbeam descends to the set position, the limit protection and the gearbox stop.
