SLIDING VANE PUMP WITH DIESEL ENGINE

Vane Pump Overview

A vane pump is a positive displacement hydraulic pump that uses rotating vanes inside a rotor to draw in and discharge liquid, creating a stable flow. It generates a pressure difference between the suction and discharge chambers by changing the volume of the compartments formed by the vanes during rotation.

Operating Principle

1. Rotor rotation: The motor drives the rotor, where vanes are mounted in slots.
2. Chamber formation: As the rotor turns, vanes are pushed outward (by centrifugal force or springs), forming variable-volume chambers between the rotor and the pump casing (stator).
3. Liquid suction: At the suction side, chamber volume increases, lowering pressure and drawing liquid in.
4. Liquid discharge: At the discharge side, chamber volume decreases, compressing the liquid and expelling it at higher pressure.

Features and Applications

• Smooth and stable operation with low pulsation.
• High volumetric efficiency, adjustable flow rate.
• Types: single vane pump (one suction and one discharge per revolution) and double vane pump (two suctions and two discharges per revolution).
• Commonly used in hydraulic systems, pumping thin liquids, or systems requiring precise flow such as machine tools and oil press systems.

• Shaft: steel alloy
• Seal: oil-resistant mechanical seal
• Speed: 1800 RPM
• Diesel engine power: 7.5 kW

Diesel Engine Overview

A diesel engine is an internal combustion engine that uses diesel fuel. It operates by compressing air inside the cylinder to extremely high pressure and temperature, then injecting diesel fuel into the combustion chamber. The fuel ignites spontaneously without the need for spark plugs, unlike gasoline engines.
