Working principle and application of vacuum tube furnace

October 08, 2022

Each independent heating zone of the vacuum tube furnace is equipped with a closed loop control system consisting of a thermocouple, a digital display intelligent regulator (PID) and a thyristor, which can realize automatic and precise temperature control and is convenient to operate. For the use requirements of the experiment, the loading and unloading materials are intermittently loaded and unloaded. Place the cartridge on the bowl bracket when loading, open and remove the sealed end cap at one end of the furnace tube, put it into the cartridge holder with the cartridge, and then install the sealing end cap on the furnace tube flange and tighten the clamp bolt. Then, the process atmosphere is passed until the oxygen content in the furnace tube reaches the process requirement, and the temperature is increased and sintered. After the product sintering process is completed, it should continue to pass a small amount of process atmosphere and cool down until the furnace temperature is lower than the process requirements before opening the furnace tube seal end cover to take out the product.

The vacuum tube furnace is characterized by simple use, reliable operation, strong anti-interference ability, stable control, convenient adjustment, and beautiful appearance. Its furnace door has an automatic power-off function when it is opened, which ensures the safety of the user to the greatest extent. Compared with ordinary heavy refractory furnaces, the whole equipment has small furnace heat storage, fast heating, large adjustment range of temperature rise and fall, and obvious energy saving effect.

Vacuum tube furnaces are widely used in materials or chemical laboratories to sinter new materials under vacuum or other atmospheric conditions. High precision SCR controller with +/-1 Â°C accuracy and 51-segment program. Vacuum tube furnace, mainly used for filling gas protection and vacuum high temperature experiments.

The vacuum tube furnace is a high temperature vacuum tube furnace which is heated by a silicon molybdenum rod and has a temperature of up to 1600 Â° C. The mechanical pump and the molecular pump simultaneously act to achieve a vacuum of 10-5 torr. Widely used in materials or chemical laboratories to sinter new materials under vacuum or other atmospheric conditions. High precision SCR controller with +/-1 Â°C accuracy and 51-segment program.
Scooter Adapter
Scooter car also called body car, camera car, balance car etc, and the scooter Adapter is the important accessory for the scooter car. Yidashun can offer the scooter adapter from 12V to 48V, such as 12V 8A, 15V 5A, 24V 4A, 36V 2A, 42V 2A and 48V 2A and so on.

Yidashun's electric scooter charger have the advantage of Over-current protection, over-voltage protection, over-temperature protection, under-voltage protection, short-circuit protection, anti-backflow, and automatic shut-off protection etc, to ensure the safety during using.
