Vacuum coating of mobile phone of vacuum coating machine

With the continuous improvement of people's daily life, the use of mobile phones has become very common. Although mobile phones bring convenience to people, the harm of their radiation to the human body is becoming more and more serious.

Studies have shown that the intensity of electromagnetic waves generated by mobile phones is 4 to 6 times that of space electromagnetic waves. The electromagnetic waves generated by a few inferior mobile phones are even more than 100 times of space electromagnetic waves. Mobile phone radiation can cause neurasthenia, endocrine disorders, and can affect the growth and development of children, and even lead to brain tumors in severe cases.

Oil change operation of vacuum pump of vacuum coating machine

The first thing we do is take the vacuum pump out of the vacuum plating system. Pad one end of the chassis motor higher, open the oil plug to drain the oil, turn the vacuum pump, and cover the exhaust port, so that all the dirty oil in the cavity is released from the oil drain port.

Then add 100-500ml of new oil from the air inlet and continue to rotate for more than 5-10 revolutions to clean the interior. Do this for 3-5 times, wait until the dirty oil is cleared, then install the oil drain plug, level the vacuum pump, and add new oil from the air inlet and the oil filling hole respectively, and the oil change is completed.

It is not suitable to start the motor for a long time for the oil change of the vacuum pump, so as to avoid the beating of the exhaust valve plate too violent and fatigue. It is strictly forbidden to use kerosene, alcohol and gasoline for non-disassembly cleaning of the pump.
