Audited Supplier Product features of low pressure screw air compressor
1. Adopt large rotor and low speed to ensure high performance of the machine;
2. Increase oil and gas separation equipment to ensure that the export oil content is ≤3ppm;
3. The air source of the low-pressure screw air compressor is clean, which reduces the number of cleaning nozzles of texturing machines and other equipment, and improves the quality of the finished product;
4. The heat dissipation area of the oil cooler is increased by more than 30% to ensure normal operation in summer without over-temperature;
5. Independently design the internal pressure ratio of the host to ensure a better specific power;
6. Intelligent control system, automatically adjust the exhaust volume according to the customer's usage (frequency conversion model).
7. For the texturing industry, ensure long-term continuous operation, set fault warnings, and do not stop immediately, so that customers are fully prepared for shutdown;
8. Adopting dual air outlet design, the air outlet temperature can be adjusted according to climate changes, meeting customer needs to a greater extent, and achieving high efficiency and energy saving at the same time.
1. Efficient airend
There is no intermediate transmission, so there is no energy loss; direct drive increases reliability and reduces maintenance costs; large rotors run at low speeds, with higher efficiency, lower noise, lower vibration, and lower energy consumption.
2. High-quality independent oil pump forced lubrication design
(1) Forced lubrication with independent oil pump;
(2) Ensure that there is sufficient fuel injection and a better air-fuel mixture ratio under extremely low exhaust pressure (2kg).
3. Increase customized oil and gas separation system
Increase the customized oil and gas separation system to ensure the ultimate oil and gas separation effect and ensure that the oil content of the air is less than 3ppm.
