1，概述
The pump is characterized by its suction valve and pressure valve are zero leakage,
Its suction pipe should be as short as possible,
這樣可避免非運行狀態下泵的吸入口無油液充滿。
單作用形式的泵，
And the oil level of the tank must be maintained at the same height as the suction port or above the suction port,
This avoids the non-operating state of the pump inlet without oil filled.
均向壓力管道排出同樣的油量。
敞開式的泵和全封閉式的泵的操作機構（手柄機構）是不同；
。對于全封閉式的泵，其驅動部分在機殼內，
And the oil is discharged to the pressure pipe while the handle is moving in the other direction.
The double acting form of the pump, when the operating handle moves forward or backward,
The same amount of oil is discharged to the pressure pipe.
The open type pump and the fully enclosed pump operating mechanism (handle mechanism) are different;
雙作用形式的泵，在操作手柄向前或向后運動時，
The For an open pump, the drive part is exposed,
Recommended for regular maintenance (cleaning and lubricating oil).
此泵的特點是其吸入閥和壓力閥均為零泄漏，
其吸入管應盡可能短，
且油箱的油面必須和吸入連接口保持同樣的高度或高于吸入口，
The For fully enclosed pumps, the drive section is in the housing,
There is oil lubrication and therefore no maintenance
In the operating handle in one direction to move into the oil,
