Shandong Hengrong electric hydraulic-driven gas booster has a maximum power of 55kW. It can directly boost low-pressure gas to high pressure with a maximum output pressure up to 200MPa. Adopting a hydraulic drive solution, the equipment features easy installation and connection. It has the advantages of high cost performance, high working efficiency, large output flow and wide application range, which can meet the high-pressure and high-flow application requirements of various industries for different gases. For requirements of larger flow and higher pressure under special working conditions, please contact our company for exclusive customization.
Technical Description：
- Boosting Process: Gas pressure acts on the piston of the boosting chamber, while hydraulic oil pressure acts on the hydraulic piston of the drive chamber. Driven by hydraulic power, gas is compressed during the stroke and discharged from the high-pressure cylinder.
- During operation, the forces on the working pistons at both ends and the hydraulic cylinder piston maintain dynamic balance at all times. The booster adopts a long-stroke and low-frequency design. Gas can be cooled synchronously during compression to prevent excessive outlet gas temperature and reduce equipment wear.
- The piston features a multi-seal structure for zero-leakage design, ensuring the gas in the pressurizing chamber will not be contaminated by hydraulic oil from the drive chamber.
- When the output pressure reaches the set value, the booster automatically stops operation without extra energy consumption. When the pressure falls below the set value, the booster starts automatically to replenish pressure.
- If the oil tank liquid level is too low, the liquid level relay sends a signal and the system shuts down automatically. If the oil temperature of the tank is excessively high, the oil temperature relay sends a signal for automatic system shutdown.
- The equipment requires a 380V three-phase four-wire power supply.
Two-stage Boosting: Its working principle is basically the same as that of the single-stage booster. The main difference is that the inner diameter of the second-stage booster cylinder is smaller than that of the first-stage booster cylinder, resulting in a different boosting ratio. The gas undergoes secondary boosting to raise low-pressure gas to a higher pressure, and an inter-stage cooling device is equipped between stages.
Premium Choice for High-end Applications：
- When the boosting medium is flammable gases such as oxygen, hydrogen and ethylene, explosion-proof motors and explosion-proof junction boxes can be equipped.
- This series of equipment can adopt variable displacement pumps for power supply. Under different working conditions, the hydraulic pump displacement can be adjusted automatically or manually with the change of working pressure, so as to change the output flow of the booster. It realizes the working mode of large flow at low pressure and small flow at high pressure, making the boosting system faster in pressurization, higher in working efficiency and more energy-saving.
