Vacuum furnace - good protection maintenance methods:
2) vacuum furnace for a long time need not when, it is necessary to properly keep the system with cooling water should be put on net. Especially in the winter should adhere to the indoor temperature above 10 ℃, smooth with antifreeze bad equipment and adhere to the outstanding conditions;
3) work to introduce choose 46 anti-wear hydraulic oil, oil using oil temperature within 15 ℃, 60 ℃;
4) the oil should be consented to enter the tank after strict filtering;
5) oil each replaced once a year, for the first time in the replace time shall not exceed three months;
6) check check once every six months pressure gauge,
7) the machine is stopped for a long time, the processing appearance should be wiped clean and coated with anti-rust oil.
8) don't know the structure of the machine function or procedure should not private line to start the machine;
9) machine in the process of operation, should not be for maintenance and adjustment mould;
10) when machine found serious leak or other abnormal (such as the action is not reliable, large noise, vibration, etc.) should be parking analysis reason, try to wipe out, not being put into production.
11) shall not be overloaded or beyond the maximum offset distance use;
12) vacuum furnace for a long time need not when, vacuum box should be insured deposit under the vacuum condition, all equipment cooling water should be put on net. Especially in the winter should adhere to the indoor temperature above 10 ℃, smooth with antifreeze bad equipment and adhere to the outstanding conditions;
13) before beginning each technical process, should be measured a heater resistance and insulation resistance to ground, ensure no short circuit, open circuit representation;
14) regularly check system all wiring is loose or break line, such as found that should tighten loose place, will break from cohesion;
15) heating chamber, such as attack damage need to replace, otherwise the heat preservation effect;
16) to check the electric control cabinet back each relay is instrumentation, such as loose surface are detected, should be timely put tight;
17) time to arrange, electric control cabinet to remove adherent dust, crushed, metal scraps, etc., don't make it work for a long time in high temperature, moisture, dust pollution environment;
18) claims that did not work, please send electric control cabinet back all the status of the circuit breaker from ON to OFF, or directly closed the total power, avoid shock disturbance;
19) using the touch screen, pay attention to the operation process, avoid the wrong operation; Touch screen together to gently, avoiding the damage to the screen.
