Which Type of Hydraulic Pump Used in Excavator: A Comprehensive Guide
In the ever-evolving field of construction machinery, the hydraulic pump plays a pivotal role, especially in excavators. These powerhouses transform mechanical power into hydraulic energy, enabling the various functionalities of excavators from movement to digging. we delve into the various types of hydraulic pumps used in excavators and how Kyotechs provides unparalleled solutions for your machinery needs.
Introduction to Hydraulic Pumps in Excavators
Hydraulic systems are the lifelines of excavators, and at the core of these systems are hydraulic pumps. These pumps convert mechanical power from the engine into hydraulic energy, which powers the movement of the excavator's arm, boom, and attachments. The right choice of hydraulic pump is critical for efficient operation, influencing both performance and durability.
Types of Hydraulic Pumps Used in Excavators
Understanding the types of hydraulic pumps can guide operators in making informed decisions about maintenance and replacements. Here are the main types commonly used in excavators:
1. Gear Pumps: Simple and robust, gear pumps are known for their durability and ease of maintenance. They consist of two gears meshing together to create a flow of hydraulic fluid. While they are cost-effective, their efficiency is generally lower compared to other types. Gear pumps are suitable for low-pressure applications.
2. Vane Pumps: Vane pumps are often used for medium-pressure applications. They consist of vanes mounted on a rotor, which spins inside the cavity. The movement of the vanes creates a vacuum that helps in drawing and pushing the fluid. These pumps offer better efficiency than gear pumps but aren’t as robust.
3. Piston Pumps: Known for high efficiency and versatility, piston pumps cater to high-pressure operations. They use multiple pistons moving in a cylinder to create pressure and flow. Although more expensive, they provide the best performance and are often used in high-demand excavators.
Each type has its specific use case, determined by the unique demands of the excavation task at hand. Selecting the appropriate hydraulic pump ensures that your excavator operates at optimal performance levels.

FAQS
The travel oil motor has just been repaired. The track moves faster at low throttle, but will not move at high throttle. What is the remedy?
This is because the valve plate was over-ground during maintenance and the grinding amount was too much, so the pressure between the valve plate and the cylinder plane is insufficient. At low throttle, the oil pressure is small, and it is not easy to leak between planes; at high throttle, the oil pressure increases, and overflow occurs between planes, causing the track to be unable to move at high throttle. The remedy is to add a gasket to the spring. If it is a butterfly spring, you can add an extra butterfly spring.
How to remove air from the hydraulic system?
The way to remove air is to slowly operate all functions of the hydraulic system until the air is exhausted, and check and maintain the hydraulic oil level during this process.
How to solve electrical issues in a track excavator?
Use a multimeter to check circuits, inspect fuses and relays, test the battery voltage and charging system, and check the control panel and sensors. Replace faulty components as necessary.
What causes the efficiency of hydraulic pumps to decrease?
The reasons for the decrease in efficiency include wear of internal components, filter blockage, hydraulic oil contamination and insufficient system pressure.
How can I pay the order?
We can accept payment by T/T, Trade Assurance, Paypal, or Western Union.
