一、液壓萬能試驗機主機保養：

　　Maintenance of main engine of hydraulic universal testing machine:

　　1、機器所配的夾具應涂上防銹油保管;1. The fixture equipped with the machine should be coated with rust-proof oil for storage.

　　2、由于液壓萬能試驗機的鉗口經常使用，容易磨損，氧化皮太多時，容易導致小活塞損傷漏油，所以鉗口處應經常打掃，保持清潔(最好每次做完試驗后進行清掃);2. Because the clamp of hydraulic universal testing machine is often used, easy to wear and tear, and when the oxide scale is too much, it is easy to cause damage and oil leakage of small piston, so the clamp should be cleaned regularly and kept clean (preferably after each test);3、鑲鋼板與襯板接觸的滑動面、襯板上的燕尾槽面應保持清潔，定期涂一層薄的MoS2(二硫化鉬)潤滑脂;3. The sliding surface and dovetail groove surface of the lining plate should be kept clean, and a thin MoS2 (molybdenum disulfide) grease should be coated regularly.

　　4、定期檢查鉗口部位的螺釘，如發現松動，及時擰緊;4. Check the screw at the nipple regularly, if it is loose, tighten it in time.

　　5、定期檢查鏈輪的傳動情況，如發現有松動，請將張緊輪重新張緊;5. Check the transmission of sprocket regularly. If loosening is found, please re-tighten the tensioning wheel.

　　二、控制系統保養：

　　2. Maintenance of control system:

　　1、定期檢查控制器后面板的連接線是否接觸良好，如有松動，應及時緊固;1. Check regularly whether the connection wire of the back panel of the controller is in good contact. If it is loose, it should be tightened in time.

　　2、試驗后若有一段較長的時間不用機器時，關閉控制器和電腦;2. Turn off the controller and the computer if there is a long period of time after the test when the machine is not used.

　　3、控制器上的接口為一一對應，插錯接口可能對設備造成損壞;3. The interface on the controller is one-to-one correspondence, and the wrong interface may cause damage to the equipment.

　　4、插拔控制器上的接口必須關閉控制器電源。

　　4. The interface on the plug-in controller must turn off the power supply of the controller.

　　三、油源的保養：

　　III. maintenance of oil source:

　　1、定期檢查主機和油源處是否有漏油的地方，如發現有漏油，應及時更換密封圈或組合墊;1. Check regularly whether there is oil leakage in the main engine and oil source. If oil leakage is found, the sealing ring or combination gasket should be replaced in time.

　　2、根據機器的使用情況及油的使用期限，定期更換吸油過濾器和濾芯，更換液壓油。

　　2. According to the use of the machine and the service life of the oil, the oil-absorbing filter and filter element are replaced regularly, and the hydraulic oil is replaced.

　　3、長時間不做試驗時，注意關斷主機電源。如果機器在待機狀態，轉換開關應打到加載檔，因為如果轉換開關。

　　3. When the test is not done for a long time, turn off the power supply of the main engine. If the machine is in standby state, the switch should be put in the loading file, because if the switch is in standby state.http://zrl888.com
