Hvad er fænomenet fanget olie i gearpumper

Trapped oil is a common phenomenon in gear pumps. The main reason for this phenomenon is that there is a closed volume between the oil suction and pressure chambers, and the volume size changes. In order to ensure the normal operation of the gear pump, the suction and pressure chambers of the pump must be reliably separated, and the sealed working volume of the pump must be transferred to the pressure chamber after the oil suction er afsluttet . Under overførselsprocessen, når det forseglede arbejdsvolumen hverken er forbundet til sugekammeret eller til trykkammeret, dannes en forseglet olievolumen . Hvis størrelsen af dette forseglede olievolumen ændres, genereres den hydrauliske olie, der er lukket i volumen Indfangning .
