Deck/Hand tool/615162-615165 PUMP HYDRAULIC FOR HYDRAULIC

A wide range of hydraulic pumps are available, the two most common types which are applicable to the Jacks described in the former chapter are as follows:  Hand-Operated Pumps for Hydraulic Return Jack.  To be used as the hydraulic source for the hydraulic return jack of 720 kgf/cm2 series.  Has a high and low automatic control-valve, the low pressure pump operates up to the loading of 30 kgf/cm2.  This means larger output volume and higher speed without loss of capacity.  As the safety-valve is recessed inside, operation is assured.  Applicable to hydraulic spring return jacks.

有多种液压泵可供选择，适用于前一章所述千斤顶的两种最常见的类型如下：用于液压返回千斤顶的手动泵。用作720kgf/cm2系列回油千斤顶的液压源。具有高、低自动控制阀，低压泵的负荷最高可达30kgf/cm2。这意味着更大的输出量和更高的速度而不会损失容量。由于安全阀内嵌有安全阀，因此操作安全可靠。适用于液压弹簧回程千斤顶。
