Product introduction:
Each compressor includes compression body, drive motor, lubrication system, cooling system, control system and auxiliary equipment, which is a skid mounted structure.
1. Compressor gearbox
1.1 Horizontal gearbox for easy maintenance and repair.
1.2 Two pinion rotor shafts (AGMA13, made of forged alloy steel) and one large gear shaft (AGMA13, made of forged alloy steel) have been tested for static and dynamic balance for many times.
1.3 The rotor shaft bearing is a horizontal split bearing with tilting pad, made of alloy structural steel (40CrNiMoA), and the surface of the pad is coated with Babbitt alloy.
1.4 The large gear bearing is a horizontal split composite bearing made of alloy structural steel (40CrNiMoA) and coated with Babbitt alloy.
1.5 The oil seal and gas seal are of horizontal split labyrinth structure, and the air between the oil seal and gas seal is connected to the atmosphere according to API standards.
2. Impeller: forged stainless-steel impeller processed by three-dimensional flow machining (15-5PH).
3. The big and small gears and rotors are made of forged alloy steel.
4. The inner wall of volute and gas path is provided with epoxy resin anti-corrosion coating.
5. Three intercoolers, one aftercooler
5.1 Design of inner and outer shell of water pipe and gas pipe. The cooler is a straight tube copper tube with aluminum alloy fins; The aftercooler is of shell and tube structure, which is corrosion-resistant, not easy to scale and easy to clean. The copper design margin is sufficient to ensure that the inlet temperature of stage II, III and IV is controlled within 40 degrees.
5.2 The coating material is acid and alkali resistant and is not easy to fall off.
6. Lubrication system:
6.1 Full flow main oil pump driven by main shaft.
6.2 Motor driven full flow auxiliary oil pump (380V/3Ph/50Hz, gear pump), with the same flow and pressure as the main oil pump.
6.3 The lubrication system and oil tank are in the same base (the whole oil tank is under the motor base), with a large cleaning manhole, and the oil pool is equipped with automatic temperature heater.
6.4 The oil tank is combined with the motor base, and the lubricating oil loading capacity of the oil tank is 500 liters.
6.5 Enlarged oil cooler
6.6 Oil level sight glass
6.7 Filling and drain port
6.8 10-micron double oil filter
6.9 Lubricating oil system detection instrument
6.10 The oil fume extraction device and oil mist separator of the oil tank are brought back to the oil station.
