2023 turn the page The regular maintenance and inspection of machinery and equipment is not only related to the normal operation and service life of the equipment, but also directly affects the production efficiency, safety and economic benefits of the enterprise. Its importance is undeniable. For the specific rules related to the inspection work, please refer to the following content in this article;
Inspection items: 1Whether the air storage tank pressure gauge is normal.
2.Whether there is air leakage in each pipe joint and valve.
3.Whether the parts are loose.
4.Whether the air compressor oil temperature and oil level are normal.
5.Whether the vibration, temperature, and sound of the refrigeration dryer are normal.
6.Whether the refrigerant pressure of the refrigerant dryer is normal.
7.Whether the refrigeration dryer drains normally.
8.Whether the oil level of the compressor of the refrigeration dryer is normal.
9.Whether the safety valve of the nitrogen gas storage tank is normal.
10.Whether the nitrogen storage tank filter drains properly.
11.Whether the nitrogen outlet pressure is normal.
12.Whether the pressure of the adsorption tower is normal.
13.Whether the nitrogen analyzer is normal.
14.Whether the silencer is working properly.
15.Whether the fuselage is clean or not.
In addition, PSA nitrogen generators and air compressors are prone to problems in low temperature environments, so special attention is required for winter inspections
1.The heating temperature of the machine room is not lower than 15.
2.Check whether the blowdown valve at the bottom of the air buffer tank, refrigeration dryer and filter is properly drained to prevent ice blockage and ensure that no water retention is formed.
3.Before and after stopping or starting, check whether the air buffer tank, refrigeration dryer and filter blowdown are working properly.
Clarifying the inspection items can help the operation management personnel find the faults of the equipment in a timely and efficient manner, and ensure the smooth and efficient production work. Correspondingly, the inspection personnel should also make corresponding inspection records, including the basic information of the equipment, the inspection content, the inspection time, the inspection results, the operation status of the equipment, etc. This is a complete inspection.
