Because of its good control performance and test accuracy, rail dowel has been widely used in mechanical testing of building materials and metal materials. In the laboratories of large iron and steel enterprises and quality inspection units, many electronic universal testing machines are running at high loads. However, most testers lack maintenance experience, so there are often problems of one kind or another, so what is rail dowel maintenance like?

What is the maintenance of rail dowel?

Daily maintenance to ensure the normal operation of the equipment and measurement accuracy is of great significance, because this product is a high-precision testing instrument, daily maintenance can achieve good results, electronic universal testing machine host maintenance;

1. Jig equipped with rail dowel shall be coated with anti-rust oil for safekeeping.

2. Because the jaws of the universal testing machine are often used and easy to wear, too much scale is easy to cause damage to the small piston and oil leakage, so the jaws should be cleaned frequently and cleaned after each test.

3. The sliding surface of the insert steel plate in contact with the liner plate and the dovetail groove surface on the liner plate should be kept clean and regularly coated with a thin layer of MoS2(molybdenum disulfide) grease.

4. Periodically check the screws at the mouth of the pliers and tighten them in time if they are loose.

5. Check the transmission of the sprocket regularly. If it comes loose, re-tighten the tensioner.

rail dowel: What about the maintenance of electronic universal test fuel sources?

1. Check the main engine and oil source of rail dowel regularly for oil leakage. If there is oil leakage, the sealing ring or combined pad should be replaced in time.

2. According to the use of the machine and the service life of the oil, regularly replace the oil filter and filter element, and replace the hydraulic oil.

3. If no test is performed for a long time, power off the host. If the machine is in standby state, the transfer switch should be set in the "load" position, because if the transfer switch is set in the "fast retreat" position, the electromagnetic reversing valve will be powered all the time, thus affecting the service life of the equipment.

4.rail dowel is an advanced product in the testing machine. Common hydraulic testing machines use hydraulic oil to drive their operation. The use of hydraulic oil will destroy the environment and does not meet people's needs for green life. The electronic testing machine adopts electro-hydraulic servo to achieve clean and pollution-free effect.
