GA-250W ~ 450W screw compressors are designed, manufactured and tested according to strict standards. Two-stage compression, each stage of the scientific distribution of pressure and improve volumetric efficiency ZIQI two-stage compression injection screw machine at the same power rate, single-stage compression than the injection screw compressor 12% -18% more gas. In other words, under the same gas compression, two-stage compression can reduce power by 15% on average compared to single-stage compression. Rotor and bearing force is small, with the rotor diameter, low speed, so the operation is more reliable.

Air end: ·Low noise: a unique rotor type line, making the host low-speed low-grade vibration classification operation, effectively reducing the air flow pipeline vibration and reduce noise ·High reliability: superior pressure distribution, reduce bearing load, making the bearing life up to 150000 hours Unique rotor profile, making the yin and yang rotor height engagement, long service life compression stage, effectively reduce oil leakage, which helps to form oil film protection rotor ·Super energy-saving: Adopting superior pressure ratio distribution, greatly improving the compression efficiency Adopting inter-stage cooling, close to isothermal compression;
Motor: ·The frame and the end cap of the motor are made of cast iron material so that the gap between the rotor and the spindle is uniform; ·Design speed, torque and operating parameters to meet the compressor load requirements; ·Designed with SKF heavy-duty bearings, greatly increasing the stability and life of the motor; ·High-efficiency motor with F-class insulation, B-class temperature rise, longer life, more able to adapt to harsh environments; ·The motor adopts the IP55 degree of protection of the motor, effectively prevent dust and water into the motor;
Electrical control system: ·main control components adopt imported famous brand products, optimized integration in one body, high reliability, long running time; ·the PLC with intelligent, intelligent, and more intelligent can be programmed to control the operation of the whole unit in the most cost-effective way.
Transmission system: ·the motor and host adopt integrated gear transmission system. effective, reliable and solid design ·the carefully selected high-speed gear is mounted on the shaft of the connection of the motor and the host. ·the elastic coupler direct drive, combining the motor and the main engine, the transmission efficiency is high, the operation is reliable.
Oil Tube: ·Selection of Italian Manuli high-pressure tubing, pipe life than ordinary 5 times longer, using a purple exclusive lock technology, no oil spills;
Cooling system: ·Large area of high quality oil cooler and rear cooler. ·Extend the service life of lubricants, filters and seals. ·Unique low temperature difference design, with high temperature and high humidity environment for the design premise, suitable for any regional environment.
Transmission system: ·Imported filter imported filter, dust removal efficiency of 99.9%, to ensure that the compressor host dust-proof; ·Intake valve assembly specially designed servo cylinder, with a check function, no need to install the oil circuit check valve and the oil valve; ·Unique external air pre-filter to keep the machine clean inside, to extend the maintenance cycle, easy disassembly and cleaning;
