Maintenance and maintenance of universal material testing machine

The universal material testing machine uses the DC servo motor as the power source, the large liquid crystal display displays the test data and the test state, and the control of the test process is realized by the automatic control of the single chip microcomputer. By sending the PWM pulse width modulation signal, the speed regulation of the motor is realized, and the adjustable speed of the test machine is realized. . Please read the instruction manual carefully before using the machine. After fully understanding it, you can turn on the machine. The universal material testing machine belongs to a high precision testing instrument. Routine maintenance is of great importance to ensure the normal operation and accuracy of the equipment. Mainly mainframe, fixture, control system maintenance mainly:

One, mainframe maintenance:

1, prevent high temperature, excessive humidity, dust, corrosive medium into the test machine, regular inspection, to maintain the integrity of components.

2, it is recommended to install a regulated power supply, especially the occasional abnormal equipment.

3, regularly check the transmission situation of the sprocket. If there is any loosening, please retighten the tension wheel.

4, we need to clean up the ball screws every six months. When we clean up, we first clean the lead screw with gasoline and then apply a layer of grease.

5. The sliding surface of the steel plate and the lining board, the swallow tail groove surface of the lining board should be kept clean, and a thin layer of MoS2 (molybdenum disulfide) grease can be regularly coated.

6, regularly check the transmission situation of the sprocket. If it is found loose, please retighten the tension wheel.

All parts of the tension test machine should be cleaned regularly, and then the use of cotton yarn with a small amount of oil after the clean surface is cleaned to prevent rust. During the rainy season, we should pay more attention to wipe and cover the dust with dust cover.

Two. Fixture maintenance

1, the machine should be coated with anti rust oil.

2, due to the frequent use of the jaws of the electronic universal testing machine, it is easy to wear and wear. When the oxide skin is too much, it is easy to cause the small piston to damage the oil. So the jaw should be cleaned regularly and kept clean (best to be cleaned after the test is finished).

3, regularly check the screws in the jaw area, if found loose, timely tightening;

Three. Control system maintenance:

1. Regularly check whether the connecting line of the rear panel of the universal material testing machine is in good contact. If there is any loosening, it should be fastened in time.

2, if there is a longer period of time after testing, turn off the controller and computer if there is no machine.

3, the interface on the controller is one-to-one, and the wrong interface may cause damage to the equipment.

4, the interface of the controller must be switched off.
