How to maintain and maintain a universal test machine on a daily basis

The daily maintenance of detection instruments is of great significance to ensuring the normal operation of the equipment and the measurement accuracy. Host maintenance:

1. The fixtures equipped with the machine should be coated with anti-rust oil for storage;

2. BecauseUniversal testing machineThe jaws are often used, which are easy to wear. When there is too much oxide scale, it is easy to cause damage to the small piston and oil leakage. Therefore, the jaws should be cleaned frequently and kept clean (cleaned after each test); 3. The sliding surface of the steel plate and the lining plate contact the lining plate and the dovetail groove surface on the lining plate should be kept clean, and a thin layer of MoS2 (molybdenum disulfide) grease should be applied regularly; 4. Regularly check the screws in the jaws, if they are loose, tighten them in time; 5. Regularly check the transmission status of the sprocket. If there is looseness, please re-tension the tensioner; Maintenance of the oil source:

1. Regularly check whether there is any oil leakage at the main engine and oil source. If there is oil leakage, the sealing ring or combination gasket should be replaced in time;

2. Regularly replace the oil suction filter and filter element according to the use of the machine and the service life of the oil, and replace the hydraulic oil.

3. When not doing tests for a long time, be careful to turn off the mains power supply. If the machine is in standby state, the switch should be turned to the "load" setting, because if the switch is turned to the "quick reversal" setting, the solenoid reversing valve is always in the power-on state, which will affect the service life of the device. Control system maintenance:

1. Regularly check whether the connection wire on the rear panel of the controller is in good contact. If it is loose, it should be tightened in time;

2. If you do not use the machine for a long time after the test, turn off the controller and computer;

3. The interfaces on the controller are one-to-one. If the interface is inserted incorrectly, the device may be built.
