Description
Production introduction
This compressor is an oil-free gas compressor. During operation, the compressed gas medium is always clean and oil-free, suitable for use scenarios that require intake pressure boosting. It can be working for24hours continuous operation, with maintenance intervals of up to 4000-6000 hours。
Characteristics of this compressor
Adopting vertical cylinder compression, the cylinder is perpendicular to the horizontal plane, utilizing the potential energy of the piston itself to reduce power consumption, reduce usage costs, and achieve significant economic benefits, The water-cooled cooling method ensures good cooling effect of the compressor, effectively extending the service life of key vulnerable parts. The inlet is equipped with low inlet pressure protection, the exhaust end is equipped with high exhaust pressure protection, and the exhaust temperature protection is also high, Each level is equipped with a safety valve and temperature display. If there is excessive temperature and pressure, the system will alarm and shut down to ensure safe operation. There is a forklift position at the bottom of the compressor, which can easily transfer to the construction site.
