Pump Housing: The pump housing is the outer casing that encloses the internal components of the hydraulic piston pump.
It is typically made of durable materials such as cast iron or steel to withstand high pressures and provide structural integrity.
Cylinder Block: The cylinder block is a crucial component that houses the pistons. It consists of multiple cylinders where the reciprocating pistons are located. The number of cylinders can vary based on the pump size and design.
Pistons: The pistons are responsible for generating hydraulic pressure by reciprocating within the cylinders. They are usually made of high-strength materials such as steel or aluminum alloy to withstand the demanding operating conditions. The pistons are carefully machined to ensure a precise fit within the cylinders.
Swash Plate: The swash plate is a key component that converts the rotational motion of the drive shaft into reciprocating motion of the pistons. It is mounted at an angle to the drive shaft and can be adjusted to control the displacement of the pump, thereby regulating the flow rate.
Valve Plate: The valve plate is located between the cylinder block and the pump housing. It contains a series of valve ports that allow hydraulic fluid to enter and exit the cylinders. The valve plate ensures proper sequencing of the pistons' movements and controls the flow direction within the pump.
Control Mechanism: The A11VLO130 pump may incorporate various control mechanisms to enhance its performance. These mechanisms can include pressure compensators, load sensing devices, and electro-hydraulic controls. These features help optimize the pump's output and efficiency based on the system requirements.
Shaft Seal: The shaft seal prevents hydraulic fluid from leaking out of the pump and maintains a tight seal between the rotating shaft and the pump housing. It typically consists of sealing rings or gaskets that are designed to withstand high pressures and provide reliable sealing.
Bearings: The hydraulic piston pump incorporates bearings to support the rotating components, such as the drive shaft and swash plate. These bearings reduce friction and ensure smooth operation, extending the pump's lifespan and reducing wear and tear.
Suction and Discharge Ports: The pump has dedicated suction and discharge ports for the hydraulic fluid.
The suction port draws in fluid from the reservoir, while the discharge port delivers the pressurized fluid to the hydraulic system. These ports are typically equipped with fittings or connectors for easy integration into the system.
Mounting Flange: The pump features a mounting flange, which allows it to be securely attached to the system or the machine. The mounting flange ensures proper alignment and connection with other components in the hydraulic system.
