Introduction to hydraulic piston pump
The hydraulic piston pump relies on the pneumatic oil supply tank. After each start of the machine, the hydraulic oil tank must be used to reach the operating air pressure before the machine can be operated. The straight-axis swash plate type piston pump is divided into two types: self-suction type of pressure oil supply type. Pressure-supply type hydraulic pumps mostly use a gas tank with air pressure, and the hydraulic pump itself has a charge pump to supply pressure oil to the oil pump inlet. The self-priming hydraulic pump has a strong self-priming capability and requires no external force to supply oil.
