Housing and Casing: The housing and casing of the KYB87 series piston pump are typically made of robust materials, such as cast iron or steel, to withstand high-pressure hydraulic systems.
These components enclose and protect the internal parts.
Pistons: The heart of the piston pump, these cylindrical components move back and forth within their cylinders to create fluid flow. Pistons are usually made of hardened steel and sealed with high-quality rings to prevent fluid leakage.
Cylinders: The KYB87 pump contains multiple cylinders that house the pistons. These are precision-engineered to ensure a tight fit with minimal clearance to maximize efficiency.
Valve Plates: Valve plates control the flow of hydraulic fluid in and out of the pump cylinders. These plates are precisely machined to regulate fluid flow and minimize pressure loss.
Swash Plate: The swash plate is a critical component that converts the rotary motion of the drive shaft into the reciprocating motion of the pistons. It is typically adjustable, allowing for variations in flow rate and pressure.
Drive Shaft: The drive shaft connects the pump to the power source, often a motor or engine. It transmits rotational motion to the swash plate, initiating the piston movement.
Bearings: High-quality bearings reduce friction and wear in the pump, ensuring smooth and efficient operation. They are strategically placed to support moving parts such as the swash plate and drive shaft.
Seals and Gaskets: Seals and gaskets are crucial for preventing fluid leakage within the pump.
They are usually made from durable materials like rubber or synthetic compounds.
Suction and Discharge Ports: These are the entry and exit points for hydraulic fluid in the pump. Suction ports draw in fluid, while discharge ports push it out under pressure.
Pressure Relief Valve: A safety feature, the pressure relief valve protects the pump and the hydraulic system from excessive pressure. It opens to release excess pressure and closes when pressure returns to the safe operating range.
Filter and Strainer: Many KYB87 series piston pumps incorporate filters and strainers to remove contaminants from the hydraulic fluid. Clean fluid helps prevent damage to the pump and other hydraulic components.
Mounting Flange: The mounting flange allows for secure attachment of the pump to its designated location in the hydraulic system.
Shaft Seal: Located where the drive shaft exits the pump housing, the shaft seal prevents fluid from escaping and contaminants from entering the pump.
