What parts of the tensile testing machine need maintenance?

The tensile pressure testing machine must be maintained frequently when it is not in use. This can prolong the service life of the equipment. Which specific areas should be maintained? OTS technical staff will answer your questions professionally:

It is suitable for testing tensile strength, peeling, elongation at break, tearing strength and mechanical properties of leather, textiles and other materials. This machine has a brand computer, a variable frequency motor drive system and a full-featured general-purpose test software. The user can Edit the appropriate test method by yourself, you can complete the test function very conveniently; the test results can be queried and printed (load-two-point extension) and other curves and related test data, with overload protection, limit protection and peak hold and sample Functions such as automatic return to the initial position after breaking can be used for testing such as pulling, pressing, bending, tearing, etc. It is also suitable for testing of metals, non-metals, various special materials and finished products. It is an ideal testing equipment for industrial and mining enterprises, scientific research units, colleges and universities, engineering quality supervision stations and other departments.

Three places worth noting for maintenance of tensile strength testing machine: host machine, oil source, and control system.
Five mainframes for tensile strength testing machine

1. The fixtures equipped with the machine should be coated with anti-rust oil for storage;
2. Regularly check the transmission of the sprocket. If it is found loose, please re-tension the tensioner;
3. Regularly check the screws in the jaw area, and if they are loose, tighten them in time;
4. The sliding surface where the steel plate is in contact with the lining plate and the dovetail groove surface of the lining plate should be kept clean and regularly coated with a thin layer of molybdenum disulfide grease;
5. As the jaws of the hydraulic universal testing machine are often used, they are easy to wear and tear. When there are too many scales, it is easy to cause damage to the small piston and leak oil. )

Maintenance of oil source for tensile strength test machine in 3 aspects
1. According to the use of the machine and the life of the oil, periodically replace the oil suction filter and filter element, and replace the hydraulic oil.
2. Regularly check the main engine and the oil source for any oil leakage. If any oil leakage is found, the sealing ring or combination pad should be replaced in time;
3. When not testing for a long time, turn off the power of the host. If the machine is in the standby state, the transfer switch should be set to the "loading" position, because if the transfer switch is set to the "fast reverse" position, the electromagnetic directional valve is always energized, which will affect the service life of the device.

Four knowledge of maintenance of tensile strength tester control system
1. Plug and unplug the interface on the controller and power off the controller.
2. If the machine is not used for a long time after the test, turn off the controller and computer;
3. The interface on the controller is one-to-one correspondence. Inserting the wrong interface may cause damage to the equipment;
4. Regularly check whether the connection cable on the rear panel of the controller is in good contact. If it is loose, it should be tightened in time;
