What are the reasons for the low flow rate and low pressure of twin-screw oil pumps?

After disassembly, the rotor showed no significant wear
The gap at the edge cover is too large; give it a try. If it’s too loose, that’s usually the case
Does it seem like the clearance of the oil pump coupling is too large? (Independent of oil pressure). The reasons include clogged filters, gas inside the pump, detached valve cores, and low oil level.
If the pipeline filter isn’t clogged, it’s the crankcase coarse filter that’s blocked. It’s cold, below zero degrees; the right oil grade was chosen, and there are many bubbles present when draining the oil
