Compressed High Pressure Natural Gas Compressor For CNG Filling Station
D-type natural gas compressor, symmetrical balance type, the middle body between the slideway and the cylinder, according to user requirements can be planned long-shaped single-chamber, short-shaped single-chamber, extended-shaped double-chamber, long-short dual-chamber structure; water cooling system, In addition, all levels are equipped with intake and exhaust buffers and separators; thin oil stations are used in the lubrication system, and there are two sets of lubrication systems. When the oil pressure is low, the auxiliary oil pump system automatically starts to run. All equipment is integrated on the skid-mounted base, which has the characteristics of compact structure, good sealing performance, small starting torque, good inertia force balance, small mechanical vibration, high reliability, easy protection, and long service life.
Smoothing method: 1. No oil 2. With oil
Cooling method: 1. Water cooling 2. Air cooling 3. Mixed cooling (selected according to practical needs)
Overall structure method: fixed type, mobile type, skid-mounted type, soundproof cabin type, etc. (selected according to practical needs)
In addition to the functions of a standard station, the CNG gas filling station also fills compressed natural gas into a high-pressure gas transport semi-trailer (referred to as a semi-trailer) through a gas filling column located in the station, and transports it to the gas sub-station to refuel the car. At the same time, as an effective means of making up for pipeline gas transmission, in small and medium-sized cities far away from natural gas pipelines, semi-trailers can be used to transport compressed natural gas by road transportation to the cities where it is used. Other natural gas users supply gas.
