What is trapped oil in a hydraulic machine? What are the effects of trapped oil in hydraulic machines?

What is trapped oil in a hydraulic machine? What are the effects of trapped oil in hydraulic machines?...

Oil trapping in a four-column hydraulic machine is a relatively common phenomenon. Oil trapping refers to the phenomenon that the pressure of the hydraulic machine changes drastically when the volume occupied by the oil is changed when the hydraulic machine is closed. This phenomenon will cause pressure shock and ca...

How to solve the uneven oil supply of the four-column hydraulic gear pump during operation?

How to solve the uneven oil supply of the four-column hydraulic gear pump during operation?...

One. Uneven oil supply caused by mechanical failure The four-column hydraulic press has been used for a long time, because the oil pump drive coupling is loose or the gap is too large, the backlash becomes larger, the drive gear is worn, and it will also affect the unevenness of the oil supply of each cylinder. I...

Why does the hydraulic pump of a fully automatic hydraulic press leak?

Why does the hydraulic pump of a fully automatic hydraulic press leak?

The part of the hydraulic pump of the fully automatic hydraulic press that constitutes the sealed working space must move relatively, so there is a cooperation gap. Because there is a pressure difference between the pump chamber and the booster chamber, the cooperation gap will inevitably leak, and the leak will affe...
