What is the use of a vacuum furnace cooling system?

A vacuum furnace is an industrial furnace heated by electric heating elements in a near-vacuum state.
The cooling system of vacuum furnace is an important part of vacuum furnace. The cooling water channel should be kept smooth, otherwise the water temperature rise will cause the shutdown. This is a problem that is often neglected in vacuum furnace work. When no one manages the vacuum furnace, it may cause great damage to the vacuum furnace.

After using for a long time, the molybdenum heating body of the vacuum furnace will become hard, shrink, fall down, fall down and lap joint first, and then melt. In order to make the heating wire of vacuum furnace exist necessary strength at high temperature and prevent hardening, collapse or sag, the construction size of the heating wire of vacuum furnace should be designed first, such as spiral resistance wire, and the bending diameter, pitch and middle diameter of the heating element should be paid attention to. The heating body is about to loosen by the vacuum furnace insulation lining, in the insulation lining put on 95 ceramic pieces, appropriately leaving its expansion space. Use position should be suitable, general in 100-200mm a, and can be firmly hooked to prevent resistance wire lying on. In addition should avoid direct contact between the furnace wire each other (short circuit), generally to pad isolation sheet.

The purpose of treating cooling water with biodegradable and chemically assisted methods is to maintain a suspended state of minerals and to reduce the accumulation of sediment in rubber pipes, snake pipes and water jacket so that water flow is smooth. This is usually done with an automatic device that monitors the electrical conductivity of the water, automatically replenishes chemicals, flusher waterways, and adds fresh water. In conjunction with the attached vapor filtration system, this method also ensures pH control of the water to prevent the deposition of excess minerals in the cooling water system. Water quality tests should be carried out at least once a month after the system is working stably to prevent overtreatment or irregularity.

Why is it important to check the vacuum furnace cooling system?

Test samples of vacuum furnace housing and heat exchange materials should also be placed in the water system and weight loss tests should be conducted annually to check the treatment effect. Special attention must be paid to the serpentine cooler for diffusion pumps. It should be checked frequently. If blocked, the diffuser pump can overheat and lose function, and further cause the diffuser heater to burn out, resulting in expensive, time-consuming repairs. When a snake-like cooling pipe is blocked, disconnect the waterway from the water source and drain it with compressed air or flush with dilute acetic acid solution.
