Precautions for installation and use of compression testing machine

Compression testing machine can be used to test various physical and mechanical properties of materials such as manhole covers, cement, artificial stone, packaging boxes, marble, shock absorbers, beverage bottles, metal wires, pipes, rubber, etc., and is widely used It is widely used in casting, metallurgy, mining and other industries for mechanical performance testing and analysis research. Let's talk about what matters should be paid attention to in daily use of the pressure testing machine.                                                                        

Installation and adjustment

1. Inspection before installation

Before installation, check whether the machine parts and accessories are complete and whether they are damaged.

2. Installation procedure

Hoist the testing machine at a proper position in the test room, (the placement of the anchor bolts is determined by the user), and the shell is safely grounded.

Oil filling: Open the oil cap, use YB-N68 for the south and YB-N46 for the north with about 18Kg of anti-wear hydraulic oil, fill it to the required position of the oil tank, and allow enough time for the air to be discharged after standing still for more than 3 hours.

Turn on the power, press the oil pump start button, and then open the automatic valve to see if the workbench rises. If it rises, it means that the oil pump has supplied oil.

3. Adjustment of the testing machine level

Put the foot on the lower right side of the dynamometer of the testing machine away from the ground by 3 to 5 mm, start the oil pump motor, and place it on the lower platen table with a level of accuracy of 0, 1, and 1000, and level it according to the vertical and horizontal directions of the machine base. Adjust to within the ± grid. When the water is uneven, use an oil-resistant rubber plate to pad it. After it is level, adjust the foot on the right side of the dynamometer.

4. Test run

Start the oil pump motor to raise the workbench by 5-10 mm, find a test piece that can withstand more than 1.5 times the maximum test force and place it on the appropriate position on the lower platen table.


1. When using the compression  testing machine daily, be sure not to overload the load cell or subject to heavy blows to ensure the accuracy of the testing machine;

2. Always check whether the upper and lower limit tightening nuts of the micro switch are loose, and if they are loose, adjust them in time.

3. In the process of using the compression testing machine to carry out the pressure test, you should first confirm the tensile and compressive direction. Guiyang Vitiligo Hospital confirm whether the direct pull switch or signal light of the display is correct.

4. For daily use, do not tamper with the components in the back door of the control box.

5. The testing machine should be installed in a clean, dry, and surrounding house with no vibration and no corrosive gas influence. Do not place it in a place with high humidity so that the accuracy will not be damaged.

6. Check the tightness of the chain every six months.

7. This testing machine should be operated or supervised by a dedicated person to ensure safety.
