Machine Description:
(1) Host:
Host is the use of the fuel tank mounted under the host, the tensile space located at between of the upper crossbeam and lower crossbeam, and the compression, bending, shears test space located at between of the lower crossbeam and a host base. The host structure show as below
(2) Transmission System
Lower crossbeam’s rising and falling is the use of the motor, cycloid reducer, chain gears, and lead screw nut drive, to adjust the space of tensile and compression.
(3) Hydraulic System (piano desktop oil source)
A. Hydraulic principles
As shown below is adaptive load oil into the throttle governing system.Hydraulic oil in the tank through the motor to drive high pressure gear pump into the oil passage, flow through the check valve, 10μ high pressure filter, pressure valve, servo valve, into the cylinder. Computer sends a control signal to the servo valve, control and direction of the opening of the servo valve to control the flow into the cylinder to achieve constant test force, constant displacement control.
B. Feature:
(a) High pressure gear pump, low noise, and smooth pressure.
(b) Dynamical Systems and operations console integrated design, easy to operate, and saving experiments space.
(c) Surface after spray treatment, appearance is beautiful.
