1. Adjust the pressure regulating valve in front of the flowmeter and the oxygen producing valve behind the flowmeter according to the gas pressure and gas consumption. Do not increase the flow at will to ensure the normal operation of the equipment.

2. The opening of air inlet valve and oxygen gas production valve should not be too large to ensure the best purity.

3. The valve adjusted by the commissioning personnel shall not rotate at will, so as not to affect the purity.

4. Do not touch the electrical parts in the electric control cabinet at will, and do not dismantle the pneumatic pipeline valve at will.

5. The operator should regularly check the four pressure gauges on the machine and make a daily record of their pressure changes for equipment failure analysis.

6. Regularly observe the outlet pressure, flowmeter indication and oxygen purity, and compare them with the values on the performance page. If any problem is found, solve it in time.

7. According to the technical requirements of air compressor, cold dryer and filter, maintain and maintain to ensure air quality. The air compressor and cold dryer must be overhauled at least once a year, and the vulnerable parts must be replaced and maintained according to the equipment maintenance and repair regulations; The filter element must be replaced in time.

8. When maintaining the equipment, the gas must be cut off (the pressure gauge of the air tank shows zero) and the maintenance can be carried out.

9. Complete the daily record form.
