D type mixed cold CNG compressor
■Using the national patented technology of energy-saving non-balanced section compressor technology (patent number ZL98 2 29860.9) and high-pressure packing sealing technology, compared with the domestic average balance section compressor, the average energy saving is more than 10%, and the energy saving effect is remarkable.
D-type host overview:
■The unit is a two-row symmetrical structure. The two cranks are 180° evenly distributed. The reciprocating inertial force and the rotating inertial force are internally balanced. The unit is balanced and the vibration is small.
■The cylinders are horizontally arranged symmetrically, and the cylinder and packing are oil-free and lubricated. The design is forced to operate with less oil lubrication, which is more than 25% of the oil-lubricated compressors in China.
■The piston ring and packing seal assembly adopts imported PTFE oil-free lubricating material, which has good wear resistance and does not cause vicious accidents such as “pull cylinder”. Rotating inertia force machine balance, easy maintenance, unit operation balance, vibration is small.
■The compressor unit is integrally armored, and the motor directly drives the compressor through the flexible coupling, which is convenient for transportation and simple to install.
■ Piston ring and packing seal assembly adopt imported PTFE oil-free lubricating material or PEEK material, which has good wear resistance and will not cause any serious accidents such as “pull cylinder”.
■Air valve is the air cushion valve that won the National Science and Technology Progress Award. The “air cushion effect” generated by the air cushion slows down the impact of the valve plate on the valve seat. The valve plate is made of stainless steel. The valve spring is a special spring steel wire imported from Sweden. It has low noise and long service life. .
■The crosshead bearing surface is welded with babbitt, which has good wear resistance and low maintenance cost.
■The cylinder liner is a pre-film cylinder liner, the friction coefficient is small, the cylinder and the piston ring and the support ring are well worn, and the service life is long.
■The cooling method is water cooling or mixed cooling (ie air cooling + closed water cooling).
Water-cooled compressor adopts detachable tube-cooler, air-flow pipe, water-flow pipe, reverse flow of water and gas; small structure, good cooling effect, beautiful appearance, detachable die, easy to remove scale.
■The air-cooling unit of the mixed-cooling compressor unit is mounted on the compressor casing. The closed-type water-cooling system has a compact structure and a small footprint. It is especially suitable for the north environment and the tight place of the CNG station.
■The compressor control system adopts imported PLC programmable controller and motor soft starter to monitor the operation of the compressor unit in time to ensure the safe operation of the unit.
