功能特点:
双作用:当电机带动转子沿转动时，叶片在离心力和叶片底部压力油的双重作用下向外伸出，其顶部紧贴在定子内表面上。处于四段同心圆弧上的四个叶片分别与转子外表面、定子内表面及两个配流盘组成四个密封工作油腔。这些油腔随着转子的转动，密封工作油腔产生由小到大或由大到小的变化，可以通过配流盘的吸油窗口(与吸油口相连)或排油窗口(与排油口相连)将 oil液吸入或压出。
双联叶片泵常用于有快速进给和工作进给要求的机械加工的专用机床中,这时双联泵由一小流量和一大流量泵组成。当快速进给时,两个泵同时供 oil(此时压力较低),当工作进给时,由小流量泵供 oil(此时压力较高),同时在 oil路系统上使大流量泵卸荷,这与采用一个高压大流量的泵相比,可以节省能源,减少oil液发热。这种double联leaf片pump也常用于machine床liquid pressure系统中需要两个互不影响的独立oil路中。

These pumps have high performance and are designed for low noise operation to meet a variety of applications including injection molding machines,
The PV2R series single pump output flow range is very wide from 5.8 to 237 cm³/rev (.354 to 14.46 cu.in./rev).
The pump's drive components are combined into a cartridge form that can be supplied as a separate unit making it easy to replace the drive components
These double pumps consist of two PV2R seires single pumps connected in line within a common housing and driven by a shared shaft.
Provided with an independent suction port and two discharge ports allowing the output flow to be provided separately for each circuit.
Set the suction pressure at the pump inlet according to the values given below. Additionally use piping on the suction side with diameter as shown in installation drawing.
If installed above or on top of an oil reservoir or tank having an open top surface distance between pump inlet height should be less than 1 meter (3.3 ft). If using phosphate esters or water-containing fluids)
