德國BOSCH-REXROH，葉片泵選型指南
德國BOSCH-REXROH，葉片泵選型指南REXROTH葉片泵均為臥式、單泵殼結(jié)構(gòu)的離心泵。采用特殊的卡箍夾緊泵體與泵蓋，泵的吐出口方向可在360度的任何個位置，安裝使用方便。 砂泵的軸承組件采用圓筒式結(jié)構(gòu)，便于調(diào)整葉輪與泵體之間的間隙，維修時可整體拆除。軸承采用油脂潤滑。砂泵的軸封形式有填料密封、付葉輪密封、機(jī)械密封。
德國BOSCH-REXROH，葉片泵選型指南
Low operating noise
Extended bearing life cycle due to hydrodynamically lubricated plain bearings
Pressure and flow can be controlled
Low hysteresis
Very low control up times and down control times
Mounting and connection dimensions according to VDMA 24560/1 and ISO 3019-2
Please state the required setting in clear text on the order
(e.g. qVmax = 20 l/min; pzero stroke = 70 bar).
The pump will then be set to the desired values and the operating noise optimised accordingly.
德國BOSCH-REXROH，葉片泵選型指南
Without indication in clear text, the flow and the zero stroke
pressure will be set to the relevant maximum values and
the operating noise optimised to these maximum values.
Thanks to their specific design, type PV7... vane pumps with adjustable
displacement boast a low flow pulsation and achieve very high
repetition accuracy with low pressure peaks during the down control.
The noise optimization achieved by adjusting the height
adjustment screw provides for a low operating noise.
Hydrodynamically lubricated plain bearings ensure a long life cycle.
The axial compensation of the displacer provides optimum volumetric efficiency.
