Maintenance of hydraulic universal testing machine and maintenance of its oil source

The hydraulic universal testing machine is used for tensile, compression, bending and shear tests of various metal and non-metal materials, as well as special tests for some products. The test operation and data processing meet the requirements of gb228-2010 'Metal Tensile Test Method for Room Temperature Materials'. Next, follow the footsteps of our company's technicians to learn about the maintenance of the hydraulic universal testing machine and the maintenance of its oil source.





1. Overhaul of hydraulic universal testing machine


1. The sliding parts should be lubricated regularly, and the rust-prone parts should be coated with anti-rust oil.


2. Prevent high temperature, excessive humidity, dust, corrosive media, water, etc. from entering the instrument.


3. Always keep the equipment and computer clean to prevent corrosion.


4. The hydraulic universal testing machine should be checked regularly to maintain the integrity of all components.


5. Perform regular verification once a year.


6. Record usage.





2. Hydraulic universal testing machine oil source maintenance


1. If the machine is in the standby state, the transfer switch should be turned to the 'load' position, and the electromagnetic reversing valve is always in the open state, which will affect the service life of the equipment.


2. Regularly check the main engine and oil source for oil leakage. If oil leakage is found, the sealing ring or combination gasket should be replaced in time (each type of sealing ring and combination gasket are provided with each other)


3. The hydraulic universal testing machine often checks the changes in the oil level of the oil tank (observe the oil mark on the hydraulic source). If you find that the oil level has dropped a lot, you should add hydraulic oil to 3/4 of the oil mark in time.


4.
The viscosity of hydraulic oil will change according to the use of the machine and the oil cycle after a period of use. Therefore, it is recommended to replace the hydraulic oil once a year. (Before replacement, drain the oil first and open the drain nipple at the bottom of the outside of the tank. If possible, clean the drain with kerosene after draining the oil, and then tighten the drain nipple.)


The above is an introduction to the maintenance of the hydraulic universal testing machine and its oil source. I hope it will be helpful to you. The mechanical equipment is essentially the same, and the cooperative operation of different parts requires the correct method to make the whole experiment process smoother and the experimental data more accurate.
