Maintenance of Material Testing Machine

1. Keep tight. Textile instrument manufacturers introduce that during the use of material testing machines, due to the vibration during testing, it is easy to cause loosening. Therefore, after using the material testing machine for a period of time, the relevant parts should be tightened.

2. The use of hydraulic oil. In hydraulic rotation, N68 precision machine tool hydraulic oil can be used, or other similar specifications of oil can be used, with a kinematic viscosity of 11-14 centistrokes (100 ℃). Connect the oil pipe. When installing the oil pipe that connects the main body to the dynamometer, the inside of the oil pipe should be cleaned with kerosene first to ensure cleanliness in the oil circuit. Attention should be paid to whether the gasket at the connection is intact to prevent oil leakage under high pressure.

3. Material testing machine maintenance: use of lubricating oil. Lubricating oil can be poured on the lower jaw screw to lubricate the screw and screw nut. The machine base is equipped with an oil injection hole, which injects oil into the oil stroke to lubricate the worm gear. The scale of the oil in the oil stroke can be measured by an oil measuring needle, and the maximum oil level below the oil stroke should not exceed the lower flat part of the oil measuring needle. The lower end of the oil measuring needle is the lowest oil level inside the oil gauge.

4. Fill and drain oil. The textile instrument manufacturer introduces opening the air filter on the fuel tank, filling it with oil, and injecting about 24 kilograms of oil into the tank at once. The specifications of the oil used can be found in the manual. When draining oil, open the oil nozzle at the bottom left of the dynamometer. The service life of the oil depends on the climate in each region. If the oil starts to deteriorate or becomes dirty and unusable, it should be replaced with new oil.
