OEM Single Phase Rotary Screw Compressor , Diesel Screw Compressor
Single Phase Rotary Screw Compressor Introduction
1, Gear match and seal innovation - optimize the bottom screw rotor precision gear match and sealed, completely solve the process rotor gear disclosure fuel-air mixture and provide a gas volumetric efficiency reduces the cavity compressed air noise when fuel-air mixture passed from the high-pressure chamber to the low pressure generated the cavity compressed air noise.
2, Tooth root shape innovation - tooth root is a key factor impact the efficiency of gas produce, problem-solving method is substantially active and passive parts of the rotor tooth root technological shape revolution, SEC achieve historic leap through select the computer software cutting equation software. This SEC core technology have been far ahead in the business field.
3, length, diameter innovation - optimized twin-screw rotor length: diameter ratio, improve overall work through shortening the distance between both ends of the rotor, make it at higher pressure have a higher volumetric efficiency and significantly reduced by to the oscillation, to reduce mechanical noise and prolong life.
