Pressure measurement & monitoring

The mechanical pressure gauge with damping oil is used to produce damping when the pressure fluctuates and reduce the pointer to swing back and forth.

Gas supply system

Float flowmeter is used to control the gas flow rate. It is integrated with the equipment, and the leakage test has been carried out before leaving the factory.

Cautions

1. When the furnace temperature of the equipment is greater than or equal to 300℃, it is forbidden to open the furnace to avoid injury;
2. When the equipment is in use, the pressure in the furnace tube shall not exceed 0.125MPa (absolute pressure) to prevent damage to the equipment caused by excessive pressure;
3. When used in vacuum, the operating temperature of the equipment shall not exceed 800℃.

4. The internal pressure of the gas supply cylinder is high, and when the gas is fed into the furnace tube, the pressure reducing valve must be installed on the cylinder. It is recommended to choose a small pressure reducing valve for test, and the measuring range of the valve is 0.01MPa-0.15MPa, which will be more accurate and safe in use.
5. When the temperature of the furnace body is higher than 1000℃, the furnace tube can not be in a vacuum state, the pressure in the furnace tube and atmospheric pressure, maintain in the state of atmospheric pressure;
6. Long-term use temperature of high purity quartz pipe ≦1100℃
7. During the heating experiment, it is not recommended to close the suction valve and intake valve at the flange end of the furnace tube. If it is necessary to close the air valve to heat the sample, always pay attention to the indicator of the pressure gauge. The absolute reading of the pressure gauge should not be greater than 0.15MPa, and the exhaust valve must be opened immediately to prevent accidents (such as furnace pipe rupture, flanges flying out, etc.).
