| Product advantage: |
1. High efficiency and energy saving rotary screw air end
The air end is designed with big rotor rotating at low speed. It includes two independent compression units.It fetures high efficiency, low noise, low vibration, high reliability, low compression ratio in each stage, less leakage loss and higher volume efficiency. Under the same power, two units take the load, lower the load on each bearing making the part longer life.
2. High efficiency and energy saving permanent magnetic motor
The motors are high efficiency and energy saving permanent magnet with protection level of IP54.They are strictly selected according to the requirement of the applications of compressor.They all meet with the Grage 1 energy efficiency national standard.Both torque and load can meet the special design standard so as to achieve optimization of motor efficiency and power factors under loading conditions.The optimized coefficient has about 5%-8% advantge comparing with other motors.
3. High efficiency and energy saving filter system
High efficiency oil-gas separator with unique and simplified design, aggregated separator and oil return device.Its service life is 6000 hours.Oil filter uses low-pressure design with service life reaching as long as 4000 hours, and the high filtering degree protects bearing and rotor.
Reasons for sudden stop of screw air compressor and its treatment measures
1. Failure check
In order to thoroughly find out the cause of the failure, the organization personnel conduct a careful investigation of the possible failure locations according to the following procedures.
(1) Carefully read the air compressor operating records made by the post operators, and found that the operating current of the air compressor was as high as 602A when it failed, which was quite different from the maximum current of 520A during normal work. largest air compressor
(2) Check the electrical system and arrange for an electrician to conduct a comprehensive inspection of the components, switches, and joints of the motors and lines, and no abnormalities were found.
(3) Cranking inspection. Manual cranking is performed on the main engine of the air compressor, and the main engine runs flexibly without jamming and locking. largest air compressor
(4) Check the gas system. Check the minimum pressure valve of the gas system, the oil-gas separation core and all its joints and pipelines, and no blockages are found.
(5) The oil in the main engine of the air compressor and the batch of lubricating oil TL306 of the air compressor are sampled and analyzed. The flash point, viscosity, mechanical impurities, moisture, oxidation performance and other indicators of the oil meet the requirements. largest air compressor
(6) Check the lubrication system. Strict inspections were carried out on the oil filter, temperature control valve, oil pipe and oil-gas mixing pipe, and no blockage was found.
