What is the phenomenon of gear pump trapped oil? In order for the gear pump to continuously and smoothly supply oil, the gear meshing coefficient of overlap ε> 1 must be ensured to ensure that at least one pair of gear teeth are engaged at any instant of operation. Since ε> 1, there will be two pairs of gear meshing at the same time, that is, the original pair of meshing gear has not been disconnected, the back of a pair of gear has been engaged. This creates a closed volume between the teeth of the two pairs of teeth, called the trapped oil zone, so that the oil remaining between these two pairs of teeth is trapped in this closed volume. Gear pump with gear rotation, sleepy oil volume changes. When the volume is reduced, due to the oil can not be discharged, the oil trapped in the oil area is squeezed, the pressure increased sharply; with the continued rotation of the gear, the dead volume gradually becomes larger (the front pair of meshing gear tooth is about to be released The location, the dead volume is the largest), due to the lack of oil, trapped in the oil zone to form a partial vacuum. Oil in the sleepy oil zone, the need to drain no place to row, and need to be filled, they can not be added, this phenomenon is called trapped oil.
