At the steel rod coal grinding oil station, after breaking the outlet valve for the high-pressure oil, it was observed that the oil flowed out in pulses, with oil and air spraying out simultaneously. What could be the cause?
It could be air erosion in the oil pump, or the air wasn’t completely removed before starting the pump. This type of oil pump is usually a gear oil pump
Wrong? ? ? ? Generally, low-pressure oil pumps are gear pumps, while high-pressure oil pumps are axial piston pumps
High-pressure oil pumps are generally swashplate piston pumps, and the oil output is certainly not uniform.
Agree with the view from the 4th floor; last time I bought a swashplate piston pump, and my supervisor conducted experiments – the oil emerged in an uneven manner

Yes, the high-pressure oil in the hydraulic oil station is supplied by a piston pump, and the oil output is intermittent.
