Method of maintenance and maintenance of universal testing machine.

Universal testing machine, test box as a kind of precision testing equipment, dedicated to the research, experiment and teaching, etc., in the process of universal testing machine normal operation need to pay attention to the daily maintenance and maintenance, it is necessary, so how to preventive maintenance and good universal testing machine?Shijiazhuang zhongshi experimental equipment co., LTD.

1. Maintenance of universal testing machine.

(1) check the screw in the jaw of universal testing machine regularly, if it is loose, tighten it in time;

(2) the fixtures of the universal testing machine should be kept in anti-rust oil;

(3) the sliding surface of the inserted steel plate and the lining plate should be kept clean and coated with a thin layer of molybdenum disulfide grease on a regular basis;

(4) check the driving condition of the sprocket regularly. If there is any loosening, please re-tighten the tensioning wheel;

(5) because of the frequent use of the electronic tensile testing machine, it is easy to wear, and it is easy to cause the small piston to damage the oil, so it is better to clean it after each test.

2. Universal testing machine control system maintenance.
