When commissioning an die-casting machine accumulator, there are a number of recommendations and steps that need to be followed to ensure its safe and efficient operation.
We observe the video in the accumulator, there is an excess of nitrogen, the pressure reaches about 140, then it means that the hydraulic oil accumulator can not be flushed into too much. The excess nitrogen must be drained to give room for the hydraulic fluid accumulator to flow out.
1. Open the shut-off valve and drain the existing hydraulic oil from the nitrogen cylinder so that only nitrogen is retained to make the data more accurate. After draining, close the shut-off valve.
Accumulator shut-off valves for die casting machines2. Check the nitrogen pressure of the accumulator. Adjust to regular pressure requirement: 100-110.
Die Casting Accumulator Pressure Gauge3. When running, observe the boost pressure, whether there is any change. Normal 90-100
4. Then observe the fast pressure gauge, whether it is 100-110.
The pressure injection accumulator is not regulated by an electronic valve, so the PLC setting is normal.
The pressure to be released by the booster injection action needs to be fine-tuned by means of individual black wheel discs with handles, which need to be fine-tuned manually according to each product holder.
