General parameters of our permanent magnet vsd screw air compressors

Features of permanent magent vsd screw air compressor:

• Controller:  MAM6070 / MAM6080 PLC with touch screen display                                                                                                                                 

• Intelligent controller, simple operation, complete functions, real-time monitoring of operating conditions, convenient maintenance.

• 

• Screw Air-end / Screw air compressor block / Compressor rotors:  BAOSI / HANBELL                                                                                                                                                    

• Adopts large screw rotor, multiple shaft seals, few wearing parts, compact structure, large displacement and high stability

• 

• Permanent Magnet Electric Motor:    IP23 / IP55                                                                                                             

• Variable speed range 70hz to 240h,Speed range is from 25% to 100%,Significant energy savings,Synchronous operation,Higher torque-to-size ratio

• 

• High-frequency Inverter:                                                                                                                                 

• High effectively reduces the magnetic field interference generated by the inverter and saves electricity.

• 

• Oil Separate Tank:                                                                                                                                       

• The use of excellent oil and gas separators and precise oil and gas separation filter elements can reduce the oil content of the exhaust gas in the compressor and reduce the power consumption of the unit.

• 

• Oil Filter:                                                                                                                                             

• The oil filter adopts a filter paper rotary filter to filter out impurities in the lubricating oil, clean and lubricate, and increase the service life of the compressor

• 

• Cooling system:                                                                                                                                 

• The high-pressure cooling system is adopted, and the heat dissipation efficiency is high, so that the air compressor can still work continuously in a high temperature and high humidity environment

• 

• Intake Valve ASSY:                                                                                                                                           

• The intake valve assembly automatically adjusts the amount of intake air to achieve a more energy-saving intake state. At the same time, it has a relief function to discharge the internal air pressure

•

Screw air compressors RFQ questions:

1. we suggest replace oil filter at the first 500 hours working time for a new screw air compressor, meanwhile to replace lubrication oil and oil separator filter together, lubrication oil we advice shell brand 46# semi-syntheitic (Shell corena S3 R46).

2. after that,  replace oil filter every 1500-2000hours which according to screw air compressors working conditions,  if there is dusty, we advice to replace every 1500 hours, air filter element and oil separator filter are same, to replace them every 1500hours to 2000hours,  if expiry time, our screw air compressors PLC will alarm and show error code on PLC display.

if not replace filters over that time, and clear alarm to continue working, may cause oil lakage, which you can see oil come out from safety valve and oil seprator tank cover....

3. there are also other small problems which screw air compressors meet frequently, such ask lack of phase,fuse burnt, lubrication oil less caused overheat, cooler blocked.....welcome to contact with us please,  we have rich experience of selling and after-sales maintenance of all screw air compressors,  will give best soupport.
