What is the importance of vacuum sintering furnace cooling system?

Vacuum sintering furnace is electric heating element near the vacuum heating furnace. Vacuum furnace cooling system is an important part of vacuum furnace. Cooling water should maintain smooth, otherwise the temperature rise caused downtime. This is vacuum furnace work often neglected problems When no one management major damage may result in vacuum furnace.
Molybdenum vacuum furnace heating after long time use will harden, shrinkage, drop, lodging first lap, after fusing (melting) wait for a phenomenon. To make the vacuum furnace heating wire is necessary strength at high temperature, prevent hardening, collapsed or droop, first to design the structure of the vacuum furnace heating wire size, such as spiral wire, pay attention to the heating element bending diameter, pitch and screw pitch diameter, etc. The heating body is going to loose by vacuum furnace insulation lining, 95 ceramic on insulation lining is put aside, leave the expansion space. Shelve location should be suitable for, one is in commonly 100 ~ 100 mm, and can prevent resistance wire to lie prone on strong hook. Also should avoid furnace silk direct contact between each other (short circuit), usually to pad spacer.
Deal with cooling water with biological decomposition chemical auxiliary method, the purpose is to keep the minerals in suspended state, reduce the rubber tube, coil and water jacket in sediment accumulation, to make the water clear. This generally adopts an automatic device to complete, it can monitor the conductivity of the water, automatically added chemicals, wash water, add fresh water. Cooperate with auxiliary steam filtration system, this method can guarantee the pH of the water control, to prevent redundant mineral deposits in the cooling water system. After the system work stable, at least once a month for the water quality test case after processing or owed.
Vacuum tempering furnace shell and the heat exchange equipment material test sample should also be placed in water system, a yearly weight loss test to check the effect of the processing. Coil of diffusion pump cooler must pay special attention to. Should be check regularly. If blocked, diffusion pump will be overheating and loss of function, but also further cause the diffusion pump heater burning, cause of expensive, time-consuming repairs. When snake-like cooling water pipe plug, water will disconnect with water and the drainage and use compressed air to blow or wash with dilute acetic acid solution.
