How to install the hydraulic cylinder of the hydraulic universal testing machine and the four points of maintenance of the oil source of the equipment

The basic characteristics of the hydraulic universal testing machine are that it can achieve large tonnage at low cost, with high equipment rigidity and strong specificity. The electronic tensile testing machine has large stroke and flexible functions, which is especially suitable for small tonnage test occasions with variable functions. The hydraulic testing machine, with its chuck attachment, is traditionally designed to meet the requirements of the metal material industry, especially the steel test in the metallurgical industry. It can be said that the professionalism is relatively good. The industry has a saying that 'it can meet GB228'. Therefore, if The test object is mainly large tonnage (above 10T), and batch test occasions where test efficiency is particularly emphasized, it should be selected as the best choice. So, do you know the four points of how to install the hydraulic cylinder of the hydraulic universal testing machine and the oil source maintenance of the equipment?





1. How to install the hydraulic cylinder of the hydraulic universal testing machine


1. The hydraulic cylinder piston rod of the hydraulic universal testing machine must be flexible and light when driving the workbench to move, and there is no blocking phenomenon in any part of the entire stroke. Tighten the fastening screws after adjustment, and they should be firm and reliable.


2. Install in strict accordance with the regulations and requirements of the design drawings of the universal testing machine.


3. Extend the piston rod of the hydraulic cylinder and connect it with the driven mechanism (workbench), push and pull the workbench back and forth several times by hand, and ensure that the center of the hydraulic cylinder and the guide rail surface of the moving mechanism (workbench) are aligned The parallelism is within 0.1 mm.


Two. Four points of oil source maintenance for hydraulic universal testing machine


1. When not doing the test for a long time, pay attention to cut off the power of the host. If the machine is in the standby state, the transfer switch should be set to the 'load' position, and the electromagnetic directional valve has been energized, which will affect the service life of the device .


2. Regularly check whether there is oil leakage at the main engine and oil source. If oil leakage is found, replace the sealing ring or combination gasket in time (all types of sealing rings and combination gaskets are provided with each model)


3. Frequently check the changes in the oil tank level (observe the oil level on the hydraulic source). If you find that the oil level has dropped too much, you should replenish the hydraulic oil in time to 3/4 of the oil level.


4. According to the use of the machine and the oil period, the viscosity of the hydraulic oil will change after a period of use. Therefore, it is recommended to change the hydraulic oil once a year. Yes, if possible, clean the kerosene after draining the oil, and then tighten the drain nipple)


The above is the four points of how to install the hydraulic cylinder of the hydraulic universal testing machine and the oil source maintenance of the equipment shared by the company's technical staff. I hope it will be helpful to everyone.
