The installation skills of a well type vacuum furnace are analyzed as follows:
The 1. well type vacuum furnace has a large ventilator device to improve the temperature uniformity in the furnace.
The 2. well type vacuum furnace is controlled by multi zone, which can further improve the uniformity of furnace temperature.
The 3. well type vacuum furnace hearth with stainless steel guide barrel;
The opening and closing of the 4. well type vacuum furnace cover adopts a crane lifting or automatic hydraulic opening and closing mechanism with a guide column to ensure the stable opening and closing of the furnace cover.
The furnace cover and furnace body of 5. well type vacuum furnace are made of high temperature resistant fiber cotton. The furnace body has good thermal insulation performance, energy saving and production cost reduction.
The 6. well type vacuum furnace has no pollution, and the environmental benefit is good.
The installation of a well type vacuum furnace should follow certain principles, and the details are as follows:
Before the installation of the 1. well type vacuum electric furnace, it is first to be checked according to the basic drawings to meet the requirements.
2. check well type vacuum furnace accessories are complete. Whether the transportation process is damaged, the lining has no crack and collapse, the electric heating element has short circuit and the phenomenon of breaking off the brick.
3. electric control, temperature control and rejection should be arranged on the side of the well vacuum electric furnace. It can't be far away from the well type vacuum electric furnace. The back door of the control cabinet is larger than the wall 600mm, and the element board support is fixed with the anchor bolt.
The protective part of the live part and transmission device outside the shell of the well type vacuum electric furnace should be protected. In order to ensure the safety and reliability of operation, necessary protective measures should be set up, such as over current relay, pressure relay and automatic circuit breaker.
Before 4. well type vacuum electric furnace is dried, the resistance between electric heating element and furnace shell is measured with multimeter, and short circuit is not allowed. After drying, the application of 500V megabytes to measure the cold insulation resistance is not less than 0.5M Omega.
When the working voltage of the 5. well type vacuum furnace exceeds 36V, there should be a good grounding device.
6. different kinds of air roads should be painted in different colors according to the regulations to show the difference.
7. a flammable or explosive gas source should be placed in a special safety isolation room.
8. well type vacuum furnace is usually installed in the pit and the furnace cover on the ground elevation of about 500mm.
The main circuit cable and thermocouple compensation wire of the 9. well type vacuum furnace should be laid in the ditch, covering the cover plate.
10. after the installation is ready, the oven process is set according to the specification of the product specification.
