Electronic tensile testing machine is used for tensile, compression, bending, shearing and other tests of various materials. It is widely used in the physical property testing of non-metallic materials such as rubber industry, plastic industry, paper industry, wire industry, textile industry, latex industry, packaging industry, wood industry, footwear industry, and metal materials such as mechanical hardware, building materials, auto parts, wires and cables For physical property testing, what safety devices does the electronic tensile testing machine have? How to maintain it? Here is the editor to answer this question for you.

1. Safety device of electronic tensile testing machine

1. Strength protection: can be set by the system

2. Emergency stop device: can handle emergencies

3. Temperature over-rise preventer: protect the tested product and the test box

4. High-speed circuit protector: protect the heating circuit

5. Electronic tensile testing machine stroke protection: mechanical and computer dual protection to prevent exceeding the preset stroke

6. Motor (blower, freezer): overload thermal relay (protect the blower, freezer from overload)

7. Refrigerant high pressure protection switch: protect the compressor and extend the service life

8. Circuit breaker protector: protect the compressor and extend the service life

9. Compressor overload protection switch, ultra-high temperature overload protection switch, water shortage protection device

2. Regular maintenance of electronic tensile testing machine

1. Regularly check the screws in the jaws of the electronic tensile testing machine, and tighten them in time if they are loose;

2. Regularly check the transmission of the sprocket of the electronic tensile testing machine. If there is any looseness, please re-tension the tensioning wheel;

3. The electronic tensile testing machine will inevitably produce some dust during the test, such as oxide skin, metal debris, etc., which will not only cause wear and scratches on the surface of some parts;

4. The fixtures of the electronic tensile testing machine should be coated with anti-rust oil for storage;

5. The jaws of the electronic tensile testing machine are often used, which are easy to wear and easily cause small piston damage and oil leakage. The jaws should be frequently cleaned and kept clean;

6. The sliding surface of the inlaid steel plate and the lining plate and the dovetail groove surface of the lining plate should be kept clean. The electronic tensile testing machine should also be regularly coated with a thin layer of molybdenum disulfide grease.

The electronic tensile testing machine is a high-precision, high-tech material testing equipment, which can be used to perform tensile, compression, bending, shearing, peeling and other mechanical performance tests on metallic and non-metallic materials. Hope it can help you.
