Function of vacuum glove box

Functions of the vacuum glove box:

1. Closed loop: the vacuum glove box and the gas purification system constitute the closed loop system, and the power provided by the gas recycling gas purification system.

2, man-machine dialogue: color touch screen, Chinese interface, man-machine dialogue, easy to operate.

3. Automatic control (through color touch screen man-machine interface,PLC program control system control system)

Functions: manual/automatic control of cabinet pressure;

Manual/automatic control of gas purification system status;

The reduction process automatically controls the gas purification system;

Hand/automatic purification system recovery, purification and conversion purification column (purification twin column);

Box air automatic alarm;

Atmosphere and pressure parameter setting and hand/automatic conversion;

Parameter setting of automatic control function of gas purification system;

Refers to the system record;

Condition detection of executing mechanism of gas purification system;

Program control system errors and warnings;

4. Reduce and regenerate

The purification system USES renewable/reduced purification materials, and the reduction process is automatically controlled by the system;

To reduce the recycling is to meet the power supply and provide a mixture of hydrogen inert gases.

5, prevent wrong operation: automatic detection system by the PLC program control system in the process of working conditions and equipment operation state, if there is an error system error operation or insufficient conditions prompt instructions, equipment operation safety, operators can use the equipment more easily.

Preventive measures:

1. Check nitrogen, nitrogen changes in nitrogen bottle with the passage of time, the output pressure of nitrogen is set at 0.5mpa.

2. Check whether the vacuum pump is open normally.

3. Check the distribution of gloves.

4. Check that the upper limit of pressure should be set as low pressure of 1,0

5. Check whether oxygen and dew point are normal (oxygen is below 0.1 PPM and dew point is above -40).

6, excessive tank vacuum pump should be normally open
