Who has used Holberg’s HydroCOM variable air volume control system?
Thread Content
Horburg’s HydroCOM variable air volume control system is said to work quite well. This is the principle of \"backflow energy saving\" in compressors. HydroCOM is the abbreviation for “Hydraulically actuated Computerized controlled valves”; it is a hydraulic system for stepless regulation of air volume, developed by Holbig for reciprocating compressors. 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%. Figure 2 shows a schematic diagram of the actuator and intake valve of the HydroCOM core. 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\". The combination of advanced control theory and mechatronic technology,
The new hydrogen compressor in our facility uses the HydroCOM variable flow control system, and its performance is quite good
Can we add each other as friends and chat? My QQ number is 290676721
The HydroCOM variable air volume control system is a mature system that our unit uses. Now, a unit in Wenzhou, China, has also developed a system that performs well.
In the latest issue of “Compressor Technology”, it was mentioned that domestically produced variable-volume compressors have been put into use
Can anyone explain how it works?
It works very well and is energy-efficient； Its working principle is to achieve \"backflow energy saving\" by using a hydraulic actuator to delay the closing time of the intake valve.
Since 2006, I have been managing large compressors and am responsible for their modification, installation, and commissioning – having worked on two such units. Feel free to ask me if you have any questions, hehe
Besides the volume adjustment mentioned above, there are other options; send a picture to take a look
Our factory uses a Holbig system, but I’m not sure whether it’s because the system is too large or what else; the vibration is quite severe. In particular, the greater the load, the more vibration the compressor experiences (4M80-172.7/4-11.6-77.4/10.6-23.6-IB)
Our company uses this exact system. The manufacturer has stated that it’s best to achieve a compliance level of at least 50%; otherwise, the vibration will definitely be too high. Therefore, the compliance level is generally kept above 50%
