Installation Requirements and Maintenance
Use and Maintenance
1. Operators must carefully read the host manual, software manual and test standards; they must follow the operating procedures and operate in the correct way;
2. When testing every day, start the equipment and preheat for 10 minutes, especially in winter when the temperature is low; after the test, shut down in the correct order and cut off all power supplies;
3. The operator should clean up the iron slag remaining on the clamping surface of the jaws and the jaw seat every day, so as not to affect the durability of the equipment; the vibration after the sample is broken may cause the fasteners in the jaws to loosen, and regular inspection is required. Check to avoid large losses due to loose fasteners;
3. The screw and the transmission part should be lubricated regularly to prevent dry friction from causing damage to the transmission system;
4. If self-made test auxiliary tooling, the original main structure of the product must not be changed or damaged during installation;
5. If there is an abnormal situation during work, the power supply should be cut off immediately to stop the testing machine from running.
Installation requirements and foundation
1. Personnel preparation: Arrange operators who are proficient in the use of computers, and it is easier for personnel with a measurement operator certificate to master;
2. Item preparation: install a three-phase five-wire air switch on the wall closest to the oil source of the equipment; HM46 anti-wear hydraulic oil 50 liters;
3. Foundation production: The foundation is as shown in the figure below. The convenience of maintenance and overhaul should be fully considered when planning the installation location of the equipment; it is recommended to reserve a space of 500-800mm away from obstacles on the rear and left and right sides of the equipment; the front of the equipment should be kept no less than 2000mm Operating space; when the thickness of the original concrete foundation at the installation position is more than 150mm, you can use a water drill to drill holes according to the size of the foundation drawing; if the foundation thickness is less than 150mm, please install according to the drawing;
4. Equipment in place: The newly built foundation can be used normally after solidification for more than 7 days. After the host is in place, place the level on the workbench to adjust the level of the host. After leveling, pour cement mortar into the four anchor screw holes. The anchor nuts can only be tightened after the cement in the anchor screw holes has solidified.
