Cycloidal rotor gear pump design

Slap, so the surge natural frequency of the spring pulse frequency should be avoided in order to avoid the resonance. Inside and outside the rotor with the gap 5 and 5.1 Rotor pump power with the gap of the cylindrical outer rotor and the radial pump with the gap at about 0.03 - 0.25mm between, for large diameter, high speed large jump of pumping large value, and vice versa take a small value. Inner and outer rotor meshing tooth tip radial clearance is 0.02 ~ 0.15mm, on the oil viscosity is low, high pressure, low speed condition of the pump should be selected small value. Axial face and the face clearance between the pump cover is about 0.02 ~ 0.12mm. Meshing of the tooth tip clearance gap and affect the pump performance of the main factors , particularly the most influential face clearance, the leakage rate and pressure proportional to the cube. The greater the gap, the higher the pressure, leak more, the lower the volumetric efficiency of low viscosity, especially the diesel pump. In the design flow reserve is not the case, the gap is too large, or even to obtain the required supply pressure, of course, will not receive the oil; gap small can increase the volumetric efficiency, but the gap is too small, Jjn-r high precision and increased production costs, but also prone to jamming phenomenon. Powder metallurgy technology in October 2003 5.2 pump drive power pump drive power can be calculated by the formula N = No / Tit = APQ / Tlt (5) where,[link widoczny dla zalogowanych], Nf is the input power ( W); N0 is the output power (W); △ P is the pressure difference between the import and export pump (Pa); Q △ P is the pressure when the pump output flow (actual flow) (m3 / s); for the overall efficiency. The total efficiency of Tl: = 7 = (Nf-) / Sj '(No / Nb) = Nb / Nf ・ Q/Q0 where, for the mechanical efficiency; the volumetric efficiency; N for the mechanical loss power , w; N6 was pump oil power, w; Q0 theoretical flow for the pump, ln3 / S. Directly take into account when calculating the total efficiency, general admission = 0.45 ~ 0.75, the pressure is high,[link widoczny dla zalogowanych], the oil viscosity to take small values. 6 Conclusion At present, the overall design of cycloidal rotor pump very little relevant information, not to establish criteria for the design complete, the paper design to give a rough idea. Because the rotor parameters are linked to each other, so the selection of the parameters given in accordance with the principles of paper trial and error, modified, and finally determined.
