WE-300B liquid crystal digital display hydraulic universal testing machine
Brief introduction：The WE-300B type is used for tensile, compression and bending of all kinds
First, product introduction:
The WE-300B type is used for tensile, compression and bending of all kinds of metal materials. The shear attachment can be added to the shear test. It can also be used as a compression test for non metal materials such as plastic, concrete and cement. The simple accessories can be added, and a variety of performance tests of the belt chain, wire rope, welding strip, tile and component can be completed. This machine adopts oil cylinder under installation, low height and light weight, especially for engineering construction department.
Two. The description of the scheme
1 host
The main engine adopts the cylinder under the main engine, and the drawing space is above the main engine. The compression and bending test space is located between the lower beam and the worktable of the main engine. The whole machine is shown as shown in Figure 1.

3 transmission system
The lower beam is driven by the motor through the reducer, chain transmission mechanism and screw pair to realize the adjustment of drawing and compression space.
4 hydraulic system
After the oil pump is sucked into the oil pump through the filter oil net, the oil pump is sent to the oil delivery valve by the oil pump. When the oil hand wheel is closed, the piston is pushed open because of the oil pressure. The oil flows back to the oil tank. When the oil hand wheel is opened, the oil enters the working oil cylinder via the tubing and then passes the oil through the pressure tubing back to the oil. The valve body flows back to the tank.
5 control system
5.1 electronic test force, liquid crystal display test force time curve, test force, peak value of test force, yield force with obvious yield characteristic material, the experimental data are convenient and intuitive.
5.2. The mechanical properties of materials such as tensile strength and yield strength can be directly determined by the number and cross section area of digital input.
5.3, you can query and print the experimental results (with mini printers).
6 safety protection device
A) when the test force exceeds 3% of the maximum test force, the overload protection and the oil pump motor stop.
B) when the piston reaches the upper limit position, the stroke protection and the oil pump motor stop.
