Što je uzrok umetanja ulja u zupčanim pumpama

Kad pumpa zupčanika radi, postoji fenomen zarobljenog ulja, a razlozi za to analiziraju se na sljedeći način:
1. In the process of meshing transmission of gear pumps, in order to maintain stability and prevent collision and impact of gear teeth, it is necessary to ensure that the overlap coefficient of gear meshing is greater than 1 in the design, that is, before the previous pair of gear teeth are disengaged, the latter pair of gear teeth have already entered meshing, thus forming a closed tooth groove space between the two meshing točke .
2. Veličina prostora za utor za zube stalno se mijenja tijekom rotacije zuba zupčanika, najprije od velikih do malih, a zatim od malih do velikih . To stvara dva objektivna uvjeta za fenomen zarobljenog ulja .
3. When the enclosed tooth groove space shrinks, the oil remaining in the enclosed space cannot overflow, and the phenomenon of trapped oil occurs. At this point, the oil is subjected to strong compression, causing a sharp increase in pressure and squeezing out from any possible leaks, resulting in increased bearing load, power consumption, and oil temperature. Kad se prostor promijeni iz malih do velikih, vakuum se stvara u zarobljenom području nafte, a tlak je izuzetno nizak, što potiče isparavanje ulja i oborine plina, što rezultira kavitacijom, vibracijama i bukom .}
