What is the principle of stepless airflow regulation in the new hydrogen compressor?

It’s an old-fashioned method of regulation using inlet control valves, which is very energy-consuming. Nowadays, multiple compressors are typically used in systems to achieve large-volume regulation, which is energy-efficient and safe, without the need for backup units

A hydraulic stepless air volume control system developed by Holbig Company. Its main working principle is that the computer processes the status data related to the compressor’s operation in real time, and sends signals back to the electronic module within the actuator; the hydraulic actuator is then used to control the opening and closing times of the intake valve in real time, thereby enabling stepless adjustment of the compressor’s exhaust volume across a range of 0–100%. By delaying the closure of the intake valve, the excess gas returns to the intake manifold without being compressed, so only the amount of gas that needs to be compressed is compressed during the compression cycle. This is precisely the application of the aforementioned principle of \"reduced energy consumption through backflow\". Under the control of the HydroCOM system, the compressor’s intake valve is no longer an automatic valve that operates based on pressure differences, but rather a forced valve driven by an external power source. Of course, if the HydroCOM system fails to function properly for some reason, the dedicated valve for HydroCOM can still perform its normal function of allowing air to enter, just like a regular valve, thereby ensuring the safe operation of the production facility to the greatest extent possible. The combination of advanced control theory and mechatronic technology enables the HydroCOM system to achieve maximum energy savings while also possessing excellent control dynamics. Depending on various control requirements and designs, HydroCOM can precisely control the state parameters at each stage, such as pressure and flow rate.

Generally, in reciprocating compressors, a certain margin of capacity is required in the load power to accommodate conditions such as process adjustments, changes in load, and capacity expansion upgrades. This inevitably leads to a large amount of energy waste. The HYX-QWT variable air volume control system utilizes the principle of energy savings through backflow in reciprocating compressors, achieving energy reduction by controlling the amount of air intake to the compressor.
