Hydraulic Pump The Heart Of Hydraulic System
🔧 Hydraulic Pump, the Heart of Hydraulic System That Every Mechanic Should Know!
Compared to a hydraulic system as a human body, a hydraulic pump is like a "heart" that sends hydraulic oil to feed equipment - excavators, tractors, folklifts, cranes, factory machines, or virtually any industrial machine.
Many people mistake the hydraulic pump as a pressure generator, but in fact, the pump produces the flow rate (Flow). The pressure occurs when there is a load or resistance in the system, so understanding the principle of pump operation can help analyze the damage and maintenance.
Today, there are three common types of hydraulic pumps: the Gear Pump, which has a simple structure, is strong, low cost, is suitable for general work, the Vane Pump, which runs silently, the oil flow is uniform, and the Piston Pump, which supports high pressure, provides good performance, is suitable for machines that need a lot of power.
Before opting for a pump, many factors should be considered. Whether it is operating pressure, flow rate, engine or motor cycle speed, type of oil, cleanliness of system, installation method, including cost and service life, because choosing the right pump will keep the machine running at full capacity, reduce wear and save costs in the long run.
Another thing to know is the difference between a fixed Displacement Pump and a Variable Displacement Pump. A fixed volume pump supplies a fixed amount of oil every time it is rotated. A volume pump can change the flow rate according to system requirements, saving energy and controlling the operation more accurately.
📌 Brief summary Understanding the working principle of hydraulic pumps is not only useful to repairmen, but also allows users to choose the right equipment, diagnose initial symptoms, and effectively prolong the life of the machine.
