An important part of the vacuum furnace

        The cooling system of the vacuum furnace is an important part of the vacuum furnace.

        The road should maintain free cooling water or water temperature as a result of downtime. The Suzhou electric furnace manufacturer tells you that this is because the vacuum furnace is usually covered with neglect unattended hours, which may cause major damage in the vacuum furnace. Auxiliary biodegradable chemical method on cooling water to keep minerals suspended, lowering the hose, coiling the water jacket inside the pipe and accumulating sediments to allow the water to flow.

         It is usually done with a robot, which monitors the conductivity of the water, chemical additives for automatic replenishment, washing water, and adding fresh water. With the attached gas-phase filtration system, it can ensure the water control of the pH value to prevent unwanted mineral deposits in the cooling water system. After the system runs stably, at least once a month, the water quality is tested to prevent over or under. The test samples of the vacuum furnace shell and heat exchanger materials should also be carried out in the water system, and the weight loss effect should be checked year by year.

       Special attention must be paid to the serpentine tube cooler of the diffusion pump. Should be checked frequently. If you plug in the diffusion pump, it will overheat and lose its function, but it will also cause further diffusion pump heater burns, leading to expensive and time-consuming repairs. When the serpentine cooling pipe is blocked, the water is disconnected from the water, and the drainage is blown through with compressed air or washed with water with dilute acetic acid aqueous solution. The molybdenum vacuum heating furnace is used for accommodation, shrinking, falling, the length of a lap will harden and after fusion (melting), etc. The electric heating wire of the vacuum furnace has the necessary strength. At high temperature, the heating wire of the vacuum furnace is designed to be hardened, collapsed or dented, such as a spiral resistance wire. The heating element will loose the insulating lining, and the 95 ceramic insulating lining shelf will be appropriately expanded in the vacuum furnace space.

       The manufacturer of the heat treatment furnace tells you to use the position to adapt, 100 ~ 200 mm and a solid hook to prevent the series connection of the wire resistance. In addition, direct contact between the furnace line and each other should be avoided (short circuit), usually filled and isolated.
