A10VS0100DR/31R-PPA12N00 R910912007 internal parts wear oil pump internal parts wear will cause internal leakage. The leakage area between floating sleeve and gear end face is large, which is the main part of internal leakage. This part of the leakage accounts for about 50% ~ 70% of the total internal leakage. 

             No matter how noisy the world is, it's always surprisingly quiet to see you. No wind, no rain, leaving my eyes to look at you. Piano playing notes, slowly knead into the heart. You are all in your eyes, dotted with black and white keys with fingertips. Playing quietly.The volume efficiency of Rexroth gear pump with wear and internal leakage decreases, and the output power of the pump A10VS0100DR/31R-PPA12N00 R910912007 is much lower than the input power. Its loss is all converted into heat energy, which will cause the oil pump to overheat. If the joint plane is pressed tightly, 

          Rexroth plunger pump to work smoothly, the A10VS0100DR/31R-PPA12N00 R910912007 coefficient of gear meshing must be greater than 1, that is, at least one pair of teeth are engaged at the same time. Therefore, in the working process, a part of the oil is trapped in the closed oil cavity formed by the meshing of two pairs of teeth. Used to hate noise, hate noise; but now I miss the complaints around my ears, miss the noisy sigh. You leave very quietly, without a trace of nostalgia; I stay very quiet, only powerless monologue.

          As shown in the figure, the size of the sealing volume changes with the rotation of the gear.  resulting in cavitation, which is the oil trapping phenomenon of gear pump for A10VS0100DR/31R-PPA12N00 R910912007.
