A7V变量柱塞泵Variable Displacement Pump

A7V变量柱塞泵说明：

※斜轴式轴向柱塞泵，用于开式回路静液压传动中。

※流量与驱动转速及排量成正比，在恒定驱动转速下，可实现无级变量。

※控制装置品种齐全，用于每种控制和调节功能。

※用矿物油和抗燃液体工作。

※Variable displacement pump, axial piston, bent axis design, for hydrostatic transmissions in open circuits.

※The flow if proportional to the drive speed and the displacement and is steplessly variable at constant drive speed.

※Comprehensive programme of control devices for every control and regulation function.

※Operation of both mineral, and fire- -resistant fluids.

结构特点：Special Features

※高性能的旋转组件及球面配油盘，可实现自动对中，低周速，高效率High performance rotary group with sphericalcontrol area offering the fllwing。advantages,;elf-centering, low peripheral speed, highefficiency.

※驱动轴能承受径向载荷。Drive shaft will support radial loads.

※长寿命。Long service life.

※低噪声级。Low noise level.

注意事项

注意:泄漏油(壳体泄油)温度受压力和转速的影响，总是高于回路温度，然而要求回路中任何点温度不得超过90°。

泵的进口压力须≥0.08MPa (绝对压力)，及泄油压力( 壳体内允许的最高压力)须≤0.2MPa (绝对压力)，壳体内压力值必须等于或高于作用在轴密封上的外部压力值。

NOTES

   Important: The leakage oil (case drain oil) temperature is influenced by pressure and pump speed and is always higher

than the circuit temperature. However, at no point in the circuit may the temperature exceed 90°C.

   The minimum pressure at the suction port of the pump≥0.08MPa (absolute pressure), and the drain pressure (max.

permissible casing pressure) is 0.2MPa (absolute pressure). The pressure in the housing must be the same or greater than the

external pressure to the shaft seal.

requirements.
