Oil-Injected Air Compressor Screw Drive High Energy Saving Good Quality For General Industry
Why choose screw air compressor?
1. Easy to operate
The screen shows that press the switch to start and stop immediately. The door panel box structure of the body makes daily maintenance more convenient, simple and smooth. Most of the maintenance parts of the equipment are on one side, which ensures that the maintenance of the air compressor can be completed quickly.
2. Strong stability
The screw air compressor has high stability and stable operation, and can be applied to stable pressure supply, and has a mine mobile air compressor, which can be conveniently used in different environments.
3. Environmental protection, low noise
The high-quality main engine runs at high speed in the coolant circulation, and a shock absorber is installed on the base where the main engine motor is connected, so that the unit can effectively reduce the sound and avoid resonance. The air cooling system of the unit itself makes the axial flow fan operate with low noise.
4. High reliability
Compared with reciprocating compressors, screw air compressors have advanced internal components, reliable operation, fewer wearing parts, low failure rate and long service life.

Machine Details:
1.Control Panel
Advanced microcomputer PLC fully automatic programmable, protection device control system. English control system, easy to operate, can work automatically 24 hours without supervision.
2.Efficient Screw Airend
High-precision twin-screw rotor, triple-glazed, less wearing parts, compact structure, large air delivery, high stability.
3.Full Copper Core High Efficiency Motor
High-performance motor, insulation class F, heavy-duty bearings, 3~5% higher efficiency than similar products.
4.Intake Valve
The air intake valve can automatically adjust the air volume from 0 to 100% according to the requirements of the system air volume, and the pressure loss is small.
5.Cooler
A huge design of cooler volume to discharge 35% margin. As a result, a machine can operate at high temperature and avoid the phenomenon of carbon deposit caused by the high temperature of the compressor.
Comparion of Piston Compressor and Screw Compressor:
Screw compressors are the same as piston compressors, both of which are positive displacement compressors. As far as the use effect is concerned, the screw air compressor has the following advantages:
1. High reliability. The screw compressor has few parts and no wearing parts, so it operates reliably;
2. It has a long service life, and the interval between overhauls can reach 40,000 to 80,000 hours;
3. It is easy to operate and maintain. The screw compressor has a high degree of automation, and the operator does not need to undergo long-term professional training, and can realize unattended operation;
4. Good power balance. The screw compressor has no unbalanced inertial force, the machine can work stably at high speed, and can realize non-foundational operation, especially suitable for mobile compressors, with small size, light weight and less floor space.
5. The screw machine is a box-type structure, which is easy to install, and the installation cost of the piston machine is high;
6. The vibration of the screw machine is small, the operating efficiency is high, and the electric energy consumed by the piston machine is higher than the parameters;
7. The screw machine only needs to be replaced and maintained on time, and the piston machine has many parts and high maintenance costs;
8. The screw machine is a rotary operation with low noise, and the piston machine is a reciprocating motion with high noise.
