Tensile testing machine moving methods and precautions
First, the relocation of transportation should be noted:
Before relocation should be discharged hydraulic oil tank, each hose ends with plastic wrap to prevent sand, stone and other foreign matter into the tubing. The pendulum fixed with wire, as not to swing the pendulum thallium into the box. The gear lever strapped with wire or other items without making activities. Try to load part of the vertical transport, the main part flat during transport, do not make it roll.
Second, the test machine installation attention:
Before installing the machine should test requirements specified in the instructions: to lay the ground angle screws, and pay attention to the back of the test machine should be left between the wall and 0.7 to 0.8 meters. Dynamometer test machine part and a body portion between the ground level and should be placed in the deed can adjust the level of iron. After dynamometer fixed portion and a body portion, then connect the tubing. At both ends of the tubing into the new gasket. During the installation level testing machine test procedures shall be requested. The level of testing machines is an important part of the installation, if the installation is not level cause the following problems:
(1) The main part of the installation is not level would produce:
It is generated between the working piston and working cylinder friction tester guide wheel and the side of the working platform between uprights will produce friction, resulting in an error; usually expressed as a positive difference, and the error generally increases with the load decreases.
(2) the level of force is not part of the installation:
If the load is not part of the front and rear mounting level, will make the pendulum shaft bearings produce friction force generated by the piston friction, and the impact of three mound zero, the error is usually negative difference.
As the installation is not level above two issues arising in general which is characterized by a small load large impact on the large load small impact.
