Compressors equipment maintenance

Compressors equipment maintenance

Each compressor requires well-timed service. Under the service means change the oil, replacement of the oil and air filter, separator, check the belt tension (if it is not the compressor with direct drive), lubrication of the bearings, different type of the valve checking, replacement of the valves if necessary. Also according to the operational manual it is necessary to replace inlet valve repairing kit, minimum pressure valve, thermostat valve and return valve.

Sung Shin - VSD air compressor

Variable Frequency Driver (VFD) -reducing energy consumpsion system is produced with the required amount of air and compressor shutdown under no-load conditions. In order to minimize unnecessary energy loss through the inverter to adjust the number spin of compressor Energy consumption saving arises starting by reducing the starting current as the inverter is operated.

Some attentions of desicant air dryer (heatless type) maintenence

Tuesday - 30/07/2019 05:32

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, in fact there are many different problems  such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using  time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended  maintenance   in some factories is not seriously followed and there are deviations. To extend the life of the machine as well as compressor components and ensure operate safely Air compressors are very important to maintain regularly and technically correct.Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduced use time of compressor accessories (air filter, loc oil, oil separator ...). On the other hand, the maintenance (maintenance) recommended by the manufacturer in some factories is not guaranteed and there are deviated. To lengthen  longevity  of mạchine as well as compress

  • Pre-filter air compressor

Under normal operating conditions, the pressure drop across the filter indicates when the element needs changing typically 6 pisg or greater. However, inspect the filter element at least avey three months for proper seating and condition of the element. If the element has collapsed or can not be properly seated, replace the element.

  • After-filter air compressor

Under normal operating conditions, the pressure drop across the filter indicates when the element needs changing typically 6 pisg or greater. However, inspect the filter element at least avey three months for proper seating and condition of the element. If the element has collapsed or can not be properly seated, replace the element.
 Attention: The life cycle of filter element depends of the quality of compressed   air. Periodic attention must be paid to proper performance.

  • Control air filter of air compressor.

Control air filter should be inspected periodically and replaced when dirty. Periodic replacement of the element will ensure clean control air for operation of the valves. 

  • Purge flow rate adjustment of air compressor.

The purge flow rate should be checked periodically for proper for proper adjustment. The purge pressure for full load operation should be set at 45 pisg (3.1 parg). The purge calibration graph (Appendix) may be used for purge adjustment when the load is les than capacity.
Attention: Do not operate the dryer with no purge flow. It may damage the dryer and will void the warranty.

  • Solenoid of air compressor.

Inspect solenoid valves periodically for proper operation. The inspection should include monitoring the tower pressure gauge on each tower during the cycle. The back pressure on a regenerating tower should not be greater than 5 pisg. Higher pressure indicates either a malfuntioning valve or a cogged muffler.
Frequent monitoring of the tower pressure gauges in conjuntion with the control will give a good indication of proper operation and can assist with troubleshooting should a problem occur. Failure of a solenoid valve may results from/.

  • Faulty control circuit. Check the electrical system to verify that the solenoid coil is receiving electrical input.
  • A burned out coil. Replace the coil.
  • Clogged solenoid valve. Disassemble.
  • Damaged valve seat. Dissemble and clean.

Desiccant replacement of air compressor.

Remove contaminated desiccant from each vessel thruogh the desiccant”Drain port” located near the bottom of each vessel. Allow adequate space aove the desiccant bed motion and expansion during drying . Change the desiccant periodically for optimum dryer performance. Store any unused desiccant in an airtight container.
Attention: Use only activated alumina in your Desiccant Air Dryer.
