High pressure two stage compression rotary screw air compressor

Two stage compression features and advantages:
1.The intaked air flow after compressed by the first stage compression, connect with large amount oil mist in the cooling channel then cool fast, and then goes into the second stage compression system to be compressed and discharged under the requirement pressure, much more energy saving than one stage compression type.
2. Adopt German double rotor screw air end, big rotor and low rotary speed designing, the first and the second stage compression rotors are designed in one compression chamber, through different driving gear and driven gear ratio to get the best seal speed of the first stage and the second stage rotors gear top line, greatly improving the air end compression efficiency.
3. Adopt internal spray oil cooling type, enable air isothermal compression, saving energy by 8%.
3. Each stage compression ratio is as low as 3:1, little internal leakage, improving efficiency by15%.
Smaller compression ratio can improve running stability and reliability, high efficiency working, long using life, very low fault rate.
4. The whole unit machine can reach China national level-1 energy efficiency standard.
5. Have fixed speed type (TKL) and permanent magnetic frequency conversion motor one-piece shaft type (TKLYC).

I. TKL series of two stage compression twin screw air compressor 

Adopt advanced twin rotor screw air end imported from German and Italy, rate of 5:6, high precision of gear and seal, use SKF bearing and high grade oil seals to ensure the main engine long life and low noise operation. The air end and the diesel / EPT motor is directly connected through the high elastic coupling, no gear, less energy consumption, more air output, high reliability, long service life and low maintenance cost.

II. TKLYC series of Permanent magnetic frequency conversion two stage compression twin screw air compressor

Adopt energy saving permanent magnetic frequency conversion screw air end:
1. Adopt One-piece shaft connection structure for the permanent magnetic motor and the air end
★Permanent magnetic Motor’s rotor is directly sleeved on shaft of the air end, embedded integrated direct-connecting structure, without coupling part or transmission gear part, namely one-piece shaft, ensuring of 100% transmission efficiency.
★Taper connection is adopted for motor, and it can be assembled and disassembled very simply.
2. Adopt permanent magnetic frequency conversion EPT motor
★Permanent magnetic frequency conversion motor is the most advanced technical EPT motor, efficiency can be up to 97%, higher by 3%-5% than ordinary motor with frequency conversion device type, saving energy a lot obviously.
★Permanent magnetic EPT motor adopts high temperature resistance rare earth permanent magnet to ensure no demagnetization. Without motor bearing or sleeve, so no need lubricating grease, no need concern alignment problem, compact structure, saving space, convenient use and maintenance.
3. Wide frequency conversion, constant pressure air feeding
★Frequency application scope (0HZ-200HZ) is wide, and motor efficiency under different load is basically constant.
★The motor is big torque, EPT adaptability and loaded startup.
★The whole machine work under frequency conversion state, and can operate frequency modulation according to the client’s actual requirement of air consumption at constant pressure, realizing high efficiency and energy saving.
4. Running stable and reliable
★Machine starting up under frequency conversion state, greatly reducing the impacting to the power grid equipment, avoiding of damage to the EPT equipment and saving EPT energy when starting.
★No need to set working pressure up and bottom limit value, can operate by regulating the frequency at the setting pressure point to stabilize the pressure, so can save EPT energy by 10%-15%.
5. Energy saving a lot obviously
 Compared with the fixed speed type compressor, our permanent magnetic frequency conversion compressor can save energy by 30%; compared with the ordinary motor with frequency device  type compressor, our compressor can save energy by 5%-10%.
