Vacuum flap valve of vacuum coating machine
The high-vacuum pneumatic flap valve is a kind of compressed air as the power to change the direction of piston movement, thereby driving the valve plate to start, realizing the conduction and cut-off of the gas in the vacuum system or pipeline. This type of valve structure is relatively simple, opens and closes quickly, and can be adapted to automatic control systems. It is now used in electronics, food, metallurgy, biomedicine, atomic energy, aerospace, chemical and other medium and large equipment (such as vacuum coating equipment, vacuum furnace, vacuum Freeze drying equipment) and other wide applications.

When operating the vacuum coating equipment, you must use the correct method. Let's talk about how to perform the correct operation!

       Under the normal operation of the machine tool, to start the machine, you must first open the water pipe, and always pay attention to the working water pressure.

       At the same time, ion bombardment and evaporation should be paid special attention to the high-voltage wire connector, not to contact, to prevent electric shock. The electron gun in the coating, the outer bell on the aluminum. It is best to use lead glass to observe the window glass. Glasses should be worn to observe the lead glass to prevent X-rays from affecting the human body. For the deposition of the coating of the multilayer dielectric film, ventilation and dust removal equipment should be installed to remove harmful dust in time. Keep flammable and toxic substances, poisoning in fire.

The pickling device should be carried out on the ventilation device, and rubber gloves should be worn. Put the parts into the acid or alkali in the cleaning tank gently, without collision and splashing. In addition, the commonly used pickling tanks should be covered. Finally, the work is completed and the water should be cut off.

       Safety regulations: The use of vacuum systems, vacuum systems, high-temperature vacuum pump oil filling systems, vacuum coating machines may accidentally explode and burn, so in the process of work, the installation and operation specifications during the operation must be strictly followed. Be cautious, heat pumps Experienced scalding is dangerous, and rotating parts may hurt people. Therefore, pay attention to the inaccessible booster pump and diffusion pump during the production process. The pre-operative shields of the slide valve pump and the Roots pump must be intact. Not near.

       The winding system may be dangerous to people during operation, so the speed of the rear masking and cleaning roller is not too fast, no more than 30m/min, and no more than 10m/min.

       The vacuum coating equipment must pay attention to the above mentioned aspects when operating. In order to extend the service life of the machine, in addition to correct operation, it is also necessary to protect it.
