The hydraulic pump is a key component in the hydraulic system. It is responsible for converting mechanical energy into hydraulic energy to drive various actuators of the hydraulic system. The internal accessories of a hydraulic pump include many key components. Here are some of the main internal accessories of a hydraulic pump:
Turbine Hub (Impeller): The turbine hub of a hydraulic pump is a rotating component that is rotated by mechanical energy input to guide fluid into the pump.
Pump Casing: The pump casing is the outer casing of the hydraulic pump. It houses the turbine hub and other internal accessories and guides the fluid from the inlet to the outlet.
Inlet Port: The suction port of a hydraulic pump is where the liquid enters the pump, usually loTQed on the side of the pump casing. Liquid enters the pump through the suction port.
Outlet Port: The outlet is where liquid exits the pump, usually on the other side of the pump casing. Through the pressure port, fluid is fed into the hydraulic system.
Seals: The hydraulic pump contains a variety of seals, such as shaft seals and check valve seals, to ensure that liquid does not leak or backflow inside the pump.
Gears, Pistons, or Blades: These are the working parts of a hydraulic pump that move inside the pump and are responsible for generating pressure and pushing fluid through the hydraulic system. Hydraulic pumps can be gear pumps, piston pumps or vane pumps, depending on how they work.
Drive Shaft: The drive shaft of a hydraulic pump is connected to an external power source (usually an electric motor or engine) and transmits mechanical energy to the turbine hub, thereby starting the operation of the pump.
Filter: A filter is usually included in a hydraulic pump to filter the liquid to prevent solid particles or contaminants from entering the hydraulic system.
The design and assembly of these internal components will vary depending on the type and manufacturer of the hydraulic pump. Different types of hydraulic pumps (such as gear pumps, plunger pumps and vane pumps) also differ in their internal structure and working principles. Selecting the appropriate type of hydraulic pump and understanding its internal construction are critical to the performance of your hydraulic system.
