Kaishan KAITEC Series VJ 145 Frequency Conversion Screw type air compressor

1.Product characteristics :

Modulation Inlet Vavle:

1.Pilot vavle control 100% pressure signal to air inlet vavle

2.Modulation inlet vavle to ensure energy saving

3.Minimum pressure check vavle to maintain minium oil injection line pressure and prevent oil back flow.

High efficient airend:

1.Using high efficient airend

2.Speical designed rotors teeth produce exceptional high quality airend 3.Reliable bearing provide extended bearing operating life.

3.Using triplexbearing to prevent oil leakage.

4.Special designed, harden shaft seal O-ring to provide reliable shaft sealing.

5.Using industrial well known components in assembly, smaller motor produce more air capacity.

Cooling system:

Large cooler and larger fan allow extreme working condition.

Kan control system:aish

Total Management and contorol of all compressor operating parameters including:

1.Operating parameters display , warning and stop alarms.

2.Programmed maintenance schedule

3.Recording of compressor history

High efficient motor:

1.Large torque setting

2. F class insulation, protection grade-IP54

3.SKY bearing,low operating sound, extended operating life

4. Lubricant filler design ,lubricant can be refilled when motor is in operation.

The similarity of VJ true frequency inverter series and the ordinary screw machine:
They are both operate in a regulatory way, by setting the drive to achieve. Its biggest advantage is able to maintain the most accurate pressure pipe network system stability; gas consumption is best suited for applications where frequent changes, and changes in the use of pressure sensitive gas equipment.

The different of VJ true frequency inverter series and the ordinary screw machine:
a) VJ series of displacement can be higher than the rated displacement. If you reduce the exhaust pressure, it can be part of the power so that the room into the power required to produce larger displacement. Such as VJ-10/8 machines 8bar transferred from the exhaust pressure 7bar, its largest displacement rose to 10.9 from 10 cubic cube.
b) VJ Series allows you to higher than the rated discharge pressure conditions to run, but this time it will reduce the maximum displacement, it formerly used to produce parts for displacement power into higher pressure the power required. Such as VJ-10/8 machines 8bar transferred from the exhaust pressure 10bar, the maximum displacement of 10 cubic dropped from 8.7 cubic meters.
