Beijing Aerospace’s high-speed pumps do not have an internal oil pump; instead, they use an external gear oil pump. The pressure generated by these pumps is as high as 1 MPa, whereas the standard value should be between 0.2 and 0.6 MPa. What is the reason for this?
It could be a blockage or an off-axis gear pump.
Is the lubricating oil pressure gauge located after the cooler and filter? How can you say they blocked it?

Is there something wrong with the table? Try with a new one
Space high-speed pumps are equipped with an internal oil pump located below the high-speed shaft; this pump acts as an auxiliary pump during startup, and it stops operating once the pressure is stabilized, after which the internal oil pump takes over
