GEA ice machine

What does GEA ice machine oil pressure difference mean, and what is compressor interlock shutdown?
It refers to the pressure difference before and after the lubricating oil filter, right!
It’s either the oil filter pressure difference or the pressure difference at the inlet and outlet of the oil pump~~
It’s the lubricating oil pressure difference; if this difference is too low, the lubricating oil cannot return to the screw, resulting in insufficient lubrication. Without interlock protection, this can damage the compressor. GEA products are equipped with forced-circulation oil pumps, while some companies’ products rely on the pressure difference itself for circulation.
Check the oil level; if it is normal and the oil pump is working properly, then the oil filter is likely dirty
The oil pressure difference varies depending on the model; in most cases, it indicates the degree of clogging of the oil filter. That is, the pressure difference between the exhaust pressure and the pressure behind the oil filter
I. Pressure difference before and after the oil filter； If the pressure difference is too high, the oil filter element needs to be checked. II. The difference between the oil pump outlet pressure and the compressor discharge pressure ； If the pressure difference is too high, the fuel injection valve and the pressure of the oil pump feeding the compressor can be adjusted.
