4.The key description:

Host: this machine adopts double space gantry structure, stretching, space on the space under compression and bending.Beam lifting.Transmission part adopts circular arc tooth synchronous belt, screw pair drive, smooth transmission, low noise.Specially designed synchronous cog belt machine driven by gear system and precision ball screw pair of moving beam movement, achieve no clearance transmission.
2.Supported by:
Standard configuration: wedge stogether tensile, compression supported by a set of each.
3. The electrical control system:
(1) adopting ac servo systems and servo motor, the performance is stable, reliable, with over-current, over-voltage, overspeed, overload protection device, etc.
(2) with overload, over-current, over-voltage and displacement fluctuation limit and emergency stop protection function.
(3) the embedded controller, which guarantees the machine can realize the control of beam displacement and other parameters, which can realize constant displacement.
(4) at the end of the test, can be manually or automatically return to test the initial position at a high speed.
(5) to achieve the real physical zero, gain adjustment and test force measurement of automatic gear shifting, zero, calibration and inventory, and without any simulation adjustment link, highly integrated control circuit.
(6) electric control circuit with reference to international standards, in line with national testing machine electrical standards, strong anti-interference ability, can guarantee the stability of the controller, the experimental data accuracy.
(7) has a network interface, data transmission and storage, can be printed out and network transfer printing, can be connected to the enterprise internal LAN or Internet network.
