"What is a hydraulic pump?" "Types of pumps" etc., an introduction to hydraulic pumps.
The "hydraulic pump" is a device that draws oil from a tank and sends it to an actuator, supplying the actuator with force (pressure) and speed (flow rate) by sending oil. There are two types of pumps: "fixed displacement pumps" and "variable displacement pumps," which can be broadly categorized into three mechanisms: gear type, vane type, and piston type. Additionally, in a gear pump, two gears mesh and rotate within the casing. Inside the pump, oil is sent to the discharge side in the space between the teeth of the gears. 【Types of Pumps】 ■ Fixed Displacement Pump: The oil discharge amount (flow rate) is constant. ■ Variable Displacement Pump: The oil discharge amount (flow rate) can be changed. ★ We are sending a continuation of the hydraulic course via our newsletter!
