The effect of starting the hydraulic oil pump in the Holbig on the air valves
Thread Content
There are two cases: 1. Before it has been started, 2. After it has been started properly. What is the effect of the hydraulic oil pump once it starts on the air valve, and how can this effect on the air valve be adjusted? Could the expert send some information on how to put Horbiger into use?
When the oil pump of the Herbig system is not in operation, the compressor’s load is 100%, which means that the Herbig system is not functioning. The Herbig system regulates the level of load by controlling the opening and closing time of the air valves; for example, at 50% load, the air valve of the compressor closes, and at this point the compressor starts to do work. When the load is 50%, the unloading valve remains open, meaning that the compressor does not do any work. Detailed information can also be found online with relevant descriptions.
I have encountered a situation where, after the Holberg oil pump lost power, the load on the compressor’s first and second stages reached 100%. When restarting the oil pump, it is necessary to switch the second-stage load to manual mode before starting the hydraulic oil pump
After the Holbig oil pump stops operating, the compressor’s load rises to 100%, which can cause stress on the unit and may lead to damage to it. Our unit encountered this situation: after a power fluctuation, the oil pump stopped working, and the compressor’s load surged to 100%. The resulting shock caused the connecting rod bolts at the large and small ends of the engine to break, as well as the destruction of the crankcase cover – which was a very dangerous situation.
When conducting a safety risk assessment for the equipment, it is necessary to take into account the impact and risks posed by the hydraulic oil pump on the compressor, and to develop corresponding countermeasures.
1. Start the hydraulic oil pump. 2. Set the load to 0. 3. Start the compressor. 4. Adjust the load to the desired pressure
It depends on the situation. One case is when starting before the compressor kicks in, which is relatively simple; the second case is when adjusting the air volume while the compressor is running at 100% capacity
