4.Construction, function, 특징

This testing machine is composed of horizontal mainframe, hydraulic power pack, electric control cabinet and computer control system. See following drawing:

4.1Mainframe

구조:

It adopts pull type oil-cylinder, the piston rod retracted when it doing tensile test.

로드 측정:

A high precision load cell is installed in the front beam of the testing machine.

변위 측정:

A photoelectric encoder is installed on the side of the oil-cylinder, which is used to measure the piston stroke and it also can be approximately used for measuring deformation.

Clamp method:

Hydraulic clamping for lumber wood pull test.

Safety cage:

It equips with operated safety cage, which is used to cover the whole testing area. It can well protect the safety of the operator.

4.2Hydraulic power pack

This part is the power pack of this testing machine, which is consisted of hydraulic pump, servo valve, Electromagnet reversing valve, pressure adjustment valve, oil cylinder and other components.

일 원리:

The motor drives the gear pump, then the oil comes into the oil-cylinder after running through one-way valve, high pressure oil filter and servo valve. The high precision load cell will transmit the load signal into electrical signal and sent it to the computer. The computer will handle the date acquisition and display it in load on the monitor. Meanwhile, the computer will send control signal to the servo valve. It controls the open mouth size and orientation of the servo valve, thus to control the flow running into the oil cylinder.

High quality components:

It adopts famous brand servo valve and gear pump and other high quality hydraulic components.

Cooling system:

The power pack is equipped with cooling system to cool down the temperature of the oil. It is an intelligent cooling system, when the oil temperature is higher than the preset value, it will auto work. When it is lower than the preset value, it will auto stop working.

4.3Computer and electrical control system function and feature

3. 1. Dat에이acquisition and process system

The software based on Windows system is able to make automatic calculating of test results, 즉. 인장 강도, displacement, 등.

It can realize constant speed loading, loading hold, constant speed unloading, which can be called a total three closed loop control.

The PC software can auto store test data into Access database, the history records can be opened at any time and reviewed, printed, 등. It includes specimen info, test data, and test graphs. The graphs include load vs time, load vs displacement, 등.

1. 컴퓨터

It adopts Dell computer, English interface and English testing software. Keyboard, mouse and surge protection. 윈도우 10 system and testing software installed. It is easy to operate, computer real time display various kinds of testing curves: force- 시간, force- displacement, force- 흉한 모습, stress- strain, 등. The HP printer will print the testing results.

1. Store data:

The testing data are stored in the mdb format of Access, all the test data are auto stored in the PC in access database. The history records can be re-viewed and printed.

1. Hand control box

Hand control box is offered for move the cylinder back and forth in order to set up and perform the test. It also has an emergency stop button on it.

1. English testing software interface:
   테스트 소프트웨어: Proof Load Test (Hold at a preset load and keep it in a preset time)
