High-pressure oil pump

Thread Content

Dear sea friends, what type of pump is the high-pressure oil pump used in the high-pressure and low-pressure oil pumps of coal grinding mills? ? Last time, some details were omitted: the outlet pressure of the low-pressure oil pump is 0.45 MPa, while the outlet pressure of the high-pressure oil pump ranges from 3.5 to 31.5 MPa.

The low-pressure oil pump is a gear pump, while the high-pressure oil pump is a piston pump

Piston pumps are generally used as oil pumps in hydraulic systems.
