How Hydraulic Pumps Work: A Comprehensive Guide | Kyotechs
In the realm of heavy machinery and construction, hydraulic pumps play a pivotal role in powering various components of excavators and other equipment. Understanding how hydraulic pumps work is essential for maximizing the efficiency and durability of your machinery. Established in 2009, Kyotechs has been at the forefront of providing top-notch parts and solutions for excavators, underscoring the importance of high-quality hydraulic systems.
What is a Hydraulic Pump?
A hydraulic pump is a mechanical source of power that converts mechanical energy into hydraulic energy. It facilitates the movement of hydraulic fluid within a system, enabling the machinery to perform a multitude of tasks like lifting, digging, and moving heavy loads. Excelling in the functionality of heavy-duty equipment, hydraulic systems are vital for the smooth operation of excavators.
How Does a Hydraulic Pump Work?
1. Energy Conversion: The primary function of a hydraulic pump is to convert mechanical energy from a prime mover (like an engine) into hydraulic energy. This conversion is what powers hydraulic machinery.
2. Fluid Movement: The pump moves the hydraulic fluid (usually oil) from the reservoir to the area of the machinery that requires movement. This movement is facilitated through hoses, tubes, or pipes.
3. Pressurization: During its operation, the hydraulic pump pressurizes the fluid, creating a force that can be used to perform work. High pressure is essential in ensuring the fluid is delivered precisely where and when it is needed.
4. Control Valves: The pressurized fluid is then directed through control valves, which regulate the flow of the fluid and the direction and speed of movement within the system.
5. Return to Reservoir: Once the work is performed, the hydraulic fluid returns to the reservoir, ready to be recirculated by the pump.
Types of Hydraulic Pumps:
Understanding the different types of hydraulic pumps can aid in choosing the right one for your machinery:
- Gear Pumps: Known for simplicity and reliability, gear pumps are often used in lower pressure applications. They use gears to move fluid through the system.
- Vane Pumps: These have adjustable flow rates and are usually quieter in operation, making them suitable for more sensitive applications.
- Piston Pumps: These are highly efficient and best for high-pressure systems. Their design allows for variable displacement, making them versatile in demanding tasks.
Importance of Hydraulic Pumps in Excavators:
Hydraulic pumps are the heart of an excavator. A reliable pump ensures effective force multiplication, allowing for efficient use of power in digging or lifting heavy loads. At Kyotechs, we provide a comprehensive range of hydraulic pumps that ensure optimal performance and longevity, reaffirming our commitment to quality and innovation.

FAQS
What causes hydraulic pump cavitation?
Possible low hydraulic oil level, high oil viscosity, or restricted fluid flow.
Solution: Refill hydraulic oil, use correct viscosity oil, check and clear restricted areas.
What are the reasons that may cause the excavator engine to emit white smoke?
1. Most of the white smoke is caused by water in the cylinder. Please check whether there is water in the excavator diesel. Generally, the white smoke is emitted for a short time after starting, and there is no problem with the engine;
2. If the excavator starts to emit white smoke, the oil is not reduced, and the excavator works weakly, it means that the cylinder mattress of the excavator engine is worn;
3. Poor atomization of the injector and low cylinder pressure are also one of the reasons for the excavator engine to emit white smoke. Check the injector.
How to handle hydraulic pump pressure fluctuations?
Possible air in the system, clogged filter, or worn pressure relief valve.
Solution: Bleed air from the system, clean or replace filter, replace pressure relief valve.
