What is the maintenance schedule and safety measures for Sazhen air compressor?

I. Annual inspection According to Article 437 of the Coal Mine Safety Regulations, air compressors must have pressure gauges and safety valves. Safety valves and pressure regulators must be reliable and the pressure of the safety valve must not exceed 1.1 times the rated pressure.
Second, the monthly inspection According to the "Coal Mine Safety Regulations" Article 439 stipulates: The wind package must be equipped with reliable safety valve and discharge valve, and inspection holes. The grease inside the wind pack must be regularly removed. After the newly installed or overhauled wind pack, 1.5 times the air compressor working pressure was used for hydrostatic test. A pressure relief valve must be installed on the outlet of the wind pack. The diameter of the relief valve must not be less than the diameter of the outlet pipe, and the release pressure should be 1.25 to 1.4 times the maximum working pressure of the air compressor. The chief engineer and the ventilation mine chief must organize relevant personnel to conduct a complete overhaul on the air compressor pressure gauges, safety valves, pressure regulators, wind packs, inspection holes, wind pack outlet piping, pressure relief valves, etc., and identify problems. Timely processing. After the inspection and repair, a detailed maintenance record was made and the “who checked, who signed, and who was responsible” was insisted on.
3. Daily Inspection 1. Daily discharge of oil (water) from wind packs.
2. Test the safety valve and water cut protection (or water cut signal) three times daily and make a record.
3. Test oil pressure and over-temperature protection devices and pressure regulators once a week and make records.
4. Check cylinder suction and exhaust valves once every 100-150 hours of operation, and replace them if necessary.
5. Assist maintenance workers in regular maintenance and test work, and do a good job of daily maintenance of the equipment.
Find problems and deal with them in a timely manner. After the inspection and repair, a detailed maintenance record was made and the “who checked, who signed, and who was responsible” was insisted on.
Fourth, class inspection 1, the temperature rise of the fever parts, and recorded in the log.
2. Check and record the values ​​of wind pressure, oil pressure, water pressure, voltage and current at each test point.
3, motor, air compressor operating conditions, whether the abnormal sound or abnormal vibration in various parts.
4, the oiler, pressure regulator work.
5. The working conditions of the cooling system, fuel supply system and exhaust system shall be free from serious leakage, oil leakage and air leakage. Each safety protection and automatic control device is sensitive and reliable.
Find problems and deal with them in a timely manner. After the inspection and repair, a detailed maintenance record was made and the “who checked, who signed, and who was responsible” was insisted on.
