Features

SSD-2000B Electro-Hydraulic Servo Universal Material Testing Machine is a high-precision material testing equipment that uses hydraulic power source drive, electro-hydraulic servo control technology, computer data acquisition and processing, and can realize closed-loop control and automatic detection. It is controlled by test host and oil source. (hydraulic power source), measurement and control system, test equipment consists of four parts, the maximum test force is 2000kN.
The testing machine is a six-column, double-space structure. The stretching space between the upper beam and the lower beam is a compression space. The compression space between the lower beam and the test bench is compressed. The test space is driven by the sprocket and the screw to move the lower beam up and down automatically. Adjustment. The upper and lower beams are equipped with built-in hydraulically controlled wedge-shaped clamping jaws. The standard models are equipped with V-shaped and flat-type jaws for clamping cylindrical specimens and flat specimens for tensile testing; the lower beam bottom of standard models The end is equipped with an upper pressing plate, and the lower pressing plate with a spherical structure is arranged on the test stand, and the compression test can be directly performed.

Routine maintenance
1. Check for oil leakage before starting each time (specific parts such as: oil pipe, various control valves, fuel tanks, etc.), whether the bolts (ie, the collective name of each screw) are fastened, whether the electrical is intact; regular inspection, keep it zero Component integrity.
2. Each time the test is completed, the piston should be lowered to the lowest position and the garbage should be cleaned in time, and the workbench should be rust-proofed.
3. After running for a period of time, the necessary inspection and maintenance should be carried out on the testing machine: the sliding surface of the card board and the beam should be used to clean the residue such as steel rust; check the tightness of the chain for half a year; the lubricating parts should be regularly lubricated for the sliding parts. The rust parts are coated with anti-rust oil to keep it clean and prevent rust.
4. Prevent high temperature, excessive humidity, dust, corrosive media, water and other erosion instruments.
5. Hydraulic oil must be replaced after 2000 hours of work or cumulative work.
6. Do not install other application software in the computer, so that the test machine control system software does not work properly; the computer should be protected from viruses.
7. Before starting the machine, you must check whether the connection line between the computer and the host, the power plug and socket are correct, and whether it is loose or not.
8. Do not plug or unplug the power cord and signal cable at any time, otherwise it will easily damage the control components.
9. During the test, please do not press the buttons on the control cabinet panel, operation box and test software.
10. When testing, do not touch the device and various cables at will, so as not to affect the accuracy of the data.
11. Always check the change in tank level.
12. Regularly check whether the connector cable of the controller is in good contact. If it is loose, it should be tightened in time.
13. If the equipment is not used for a long time after the test, turn off the total power of the equipment, and periodically run the equipment idling several times during the equipment deactivation to ensure that all performance indicators are normal when the equipment is put into use again.
