Click number:- Release time:2016-03-23

Universal material testing machine is mainly used for metal, nonmetal, composite materials and products of tensile, compression, bending, shear methods such as mechanical property test, my company in universal material testing machine production and sales of about 1000 units, for every customer we will training the operation procedures and matters needing attention, maintenance and maintenance. The following is the principle of maintenance of hydraulic universal testing machine.

1, each time, check whether there is any oil leakage phenomenon on universal material testing machine before starting (specific parts such as tubing, each control valve, fuel tanks, hydraulic clamping), universal material tensile testing machine whether each screw fastening, electric are in good condition; Regularly check and maintain the integrity of its parts.

2, winter warmed up 20 to 30 minutes. Summer warm-up time for 3 to 5 minutes.

3, every time all should have finished the test will be hydraulic universal testing machine piston fell to the lowest position.

4, timely cleaning the garbage after shutdown, try to make antirust processing.

5, a day after the experiment to clean up the iron filings fixture and clamping device; Regular grade molybdenum disulfide grease daub; Adjust the space with the screw and nut periodically daub molybdenum disulfide grease; Half a year check the tightness of the chain, and add the lubricating oil; For sliding parts should add lubricating oil regularly, for easy to rust a tu rust-proof oil, keep clean and prevent rust.

6, prevention of high temperature, moisture, dust and corrosive medium, such as water erosion. Laboratory temperature 10 ℃ to 30 ℃, relative humidity from 20% to 80%

7, or a year work 2000 hours after the hydraulic oil must be replaced. Suggestion: use wear-resistant hydraulic oil no. 68 summer, winter use 46 wear-resistant hydraulic oil.

8, periodic verification once a year.

9, record usage of universal material testing machine.

Jinan road chang tester, the national instrumentation industry key enterprises. Tester thirty years professional experience, the annual output of 1000 sets of hydraulic universal testing machine, pressure testing machine 1000 units, 600 sets of electronic universal testing machine.

Crush on road chang four reasons

1, each year almost 3000 users choose middle prosperous;

2, national standard drafting, patent technology;

3, products quality inspection strictly;

4, product quality assurance for two years, after all
