Nota:
- Pn: presiunea nominala la care se garanteaza functionarea continua, durabilitatea i randamentul volumic.
- Pmax: presiunea maxima la care poate lucra pompa intermitent (max. 20 s); presiunea medie nu va depa i presiunea nominala.
- Vārfurile de presiune, de comutare, pot depa i presiunea maxima cu 20 bar.
- Randamentele volumice r|vn se garanteaza in conditii nominale i la o vāscozitate a uleiului de 30....40 mm2/s.
- Caracteristicile de mai sus sunt valabile i pentru pompele duble (la fiecare treapta in parte).
- Pentru n>1500 rot/min, P<36 500 000 / (Vg x nef)
- Functionarea pompelor la turatii ridicate, fara cavitatie, este posibila numai cu o aspiratie suficient de larga.
- Presiunea de aspiratie nu va scadea sub 0.7 bar abs.
Note:
- Pn: nominal pressure for which, continuous running, life time and volumetric efficiency are guaranted.
- Pmax: maximum pressure at which the pumps can intermittently work (max. 20 s); average pressure should be lower than Pn.
- Pressure peaks, in comutations can be 20 bar higher as Pmax.
- Volumetric efficiency r\ vn is guaranted in nominal conditions and viscosity 30....40 mm2/s.
- The characteristics mentioned above are valid also for double pumps (for every stage).
- For n>1500 rev/min, P<36 500 000 / (Vg x nef)
- Functioning at high speed, without cavitation, it is possible only with an enough large inlet.
- The inlet pressure should not decrease under 0.7 bar absolute.
