|Product name||Molecular Pump Tube Furnace|
|Furnace tube size||Φ120mmX1000mm|
|Furnace tube material||Quartz furnace tube
A furnace plug is placed on each side. The furnace plug can block the heat radiation in the center of the furnace tube and must be placed in the correct position of the furnace before heating
|Heating zone length||440mm|
|heating method||High-quality alloy heating wire, the heating wire ring is inlaid on the surface of the furnace|
|Chamber material||Alumina polycrystalline fiber, good thermal insulation performance|
|Temperature control method||Multi-stage PID intelligent program temperature control|
|control method||LCD touch screen operation, intelligent multi-segment PID programmable control
The temperature control system adopts artificial intelligence adjustment technology, has PID adjustment, self-tuning function and can compile multi-stage heating and cooling programs;
1. Adopt PID method to adjust temperature control, and can set multi-stage heating and cooling programs
2. Temperature control accuracy ±1ºC
3. With over-temperature protection, the electric furnace heating circuit is automatically cut off when the over-temperature or broken coupler is broken.
4. The instrument has the function of temperature self-tuning
5. Using touch screen operation, the heating curve can be displayed in real time, and the data can be output and stored
|Heating rate||0-20ºC/min ，Recommended 10ºC/min, can be adjusted freely according to the process|
|Operating Voltage||AC 220V Single phase 50HZ|
|Furnace structure||Double-layer shell structure is adopted, and a cooling fan is installed inside the furnace body to keep the surface temperature of the equipment low
The furnace consists of furnace material, insulation material and heating elements
The temperature control system consists of temperature control instruments, control elements and thermocouples
Furnace body and temperature control integrated structure, the furnace is fixed on the temperature controller
|Flange joint||Comes standard with two stainless steel vacuum flanges, installed mechanical pressure gauge and stainless steel shut-off valve|
|sealing system||The furnace tube and the flange are squeezed and sealed with a silicone O-ring, which is easy to remove, can be removed repeatedly, has good air tightness, and can pass through gases such as argon and nitrogen.
Both ends of the furnace tube are equipped with 304 stainless steel metal flanges, which are equipped with high-temperature fluorine rubber gaskets. There are air inlets and outlets at both ends of the flanges.
The pressure gauge is installed on the metal flange, and the precision needle valve can adjust the air intake and output volume, and nitrogen, argon, and other protective gases can be introduced
|vacuum system part|
|The main parameters||Using high vacuum molecular pump group.
The ultimate vacuum in the cold state can reach 6.67*10-3pa.
KF25 quick connection, stainless steel bellows, manual flapper valve connected with flange and vacuum pump;
Composite digital vacuum gauge display.
|Cooling system||Equipped with a water cooler, the molecular pump can be used for cooling to prevent damage to the molecular pump due to overheating
|After-sales service||One-year warranty and lifetime warranty (random accessories such as heating elements, furnace tube consumables, etc. are not covered by the warranty)|
|Notice||The pressure in the furnace tube should not be higher than 0.02MPa
Due to the high internal pressure of the gas cylinder, when the gas is fed into the furnace tube, a pressure reducing valve must be installed on the gas cylinder. It is recommended to buy a pressure reducing valve. The range of the pressure reducing valve is 0.01MPa-0.1MPa, and it will be more accurate when used. Safety
When the temperature of the furnace body is higher than 1000°C, the furnace tube cannot be in a vacuum state, and the air pressure in the furnace tube must be equal to the atmospheric pressure and kept at normal pressure
The gas flow rate entering the furnace tube must be less than 200SCCM to avoid the impact of the cold atmospheric flow on the heated quartz tube
· The long-term service temperature of the quartz tube is less than 1100°C
For sample heating experiments, it is not recommended to close the exhaust valve and inlet valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you need to always pay attention to the indication of the pressure gauge. If the pressure indication is greater than 0.02MPa, you must immediately open the vent valve to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
