A7V變量柱塞泵Variable Displacement Pump

A7V變量柱塞泵說明：

※斜軸式軸向柱塞泵，用于開式回路靜液壓傳動中。

※流量與驅動轉速及排量成正比，在恒定驅動轉速下，可實現無級變量。

※控制裝置品種齊全，用于每種控制和調節功能。

※用礦物油和抗燃液體工作。

※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.

結構特點：Special Features

※高性能的旋轉組件及球面配油盤，可實現自動對中，低周速，高效率High performance rotary group with sphericalcontrol area offering the fllwing。advantages,;elf-centering, low peripheral speed, highefficiency.

※驅動軸能承受徑向載荷。Drive shaft will support radial loads.

※長壽命。Long service life.

※低噪聲級。Low noise level.

注意事項

注意:泄漏油(殼體泄油)溫度受壓力和轉速的影響，總是高于回路溫度，然而要求回路中任何點溫度不得超過90°。

泵的進口壓力須≥0.08MPa (絕對壓力)，及泄油壓力( 殼體內允許的最高壓力)須≤0.2MPa (絕對壓力)，殼體內壓力值必須等于或高于作用在軸密封上的外部壓力值。

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.
