Routine maintenance of aluminum coating machine

2019-10-22

The application of aluminum coating machine is more and more widely, and more and more enterprises are used. In recent years, it has been praised by many users. Its use is also skillful and requires daily maintenance. Let's take a closer look at it:
First, the aluminum plating machine completes 200 painting procedures and cleans the workroom once. The method is: repeatedly wipe the wall of the vacuum chamber with a saturated solution of sodium hydroxide (note that human skin cannot directly contact the sodium hydroxide solution to avoid burns). The purpose is to make the coated aluminum (AL) react with NaOH. After the reaction, the film comes off and releases hydrogen. Then clean the vacuum chamber with clean water, and clean the dirt in the fine suction valve with a cloth moistened with gasoline.

2. When the aluminizing machine is overhauled, when the crude oil pump (slip valve pump, rotary vane pump) works continuously for one month (half month in the rainy season), the new oil should be replaced. The method is: unscrew the oil bolt, drain the old oil, and then start the pump for a few seconds to completely drain the old oil in the pump. Screw on the rewinding oil bolt and add new oil to the rated capacity (observe with oil sight glass). For continuous use for more than half a year, open the oil cover when changing the oil and wipe the dirt inside the box with a cloth.
3. The diffusion pump of the aluminizing machine has been repaired for more than 6 months. If the pump speed is slowed down or the operation is not normal, it should be filled with air, remove the connection water pipe, remove the electric furnace plate, unscrew the nozzle, and clean the pump cavity and pump with gasoline The box is then washed with detergent and water, and then cleaned with water. After the water has evaporated, install the pump water tank and add a new one. Sprinkle the pump oil, replace the body, connect the water pipe, install the electric stove plate, and restart the machine. Pay attention to leak detection before restarting. The method is: start the maintenance pump, close the gate, and after a few minutes, repair the vacuum coating machine and observe whether the vacuum degree of the diffusion pump part reaches 6x10pa, otherwise, perform leak detection. The inspection union needs to check if the head is fitted with a sealing rubber ring or if the sealing ring is crushed. Clean up the hidden danger of air leakage before heating, otherwise the diffusion pump oil will burn out the ring and cannot enter the working state.
Fourth, its maintenance coating is a physical or chemical method to apply a transparent electrolyte or metal film on the surface of the material to change the reflection and transmission characteristics of the surface of the material.
