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.

What is the matter with the engine speed drop when the excavator is working? How to solve it?
8 reasons for the engine speed drop of the excavator, 6 solutions are here!
As the name suggests, engine speed drop means the failure of the engine speed drop during the operation of the excavator. There are two manifestations of speed drop, one is a slight speed drop within 200 revolutions, and the other is a serious speed drop above 300 revolutions, which is likely to cause the excavator to suddenly shut down. There are 8 main reasons for the engine speed drop of the excavator.
1. The diesel oil circuit of the excavator is faulty. Generally speaking, when the diesel oil circuit is blocked, it may cause the speed drop phenomenon.
2. The hydraulic system of the excavator has a fault, so that the hydraulic pump cannot change the displacement normally, causing the system pressure to be too high, and the speed drop may also cause a machine failure.
3. The output power of the excavator engine itself is insufficient, the output power is lower than the rated power, and the speed is too low. There is also a problem with the main pump.
4. The engine uses fuel of poor quality or the water content of the fuel is too high, which will lead to insufficient engine power and speed drop.
5. When the air intake system leaks or is blocked, the engine will be short of air supply, resulting in incomplete combustion of fuel, and there will be speed drop and black smoke failure.
6. Due to the large gap of the solenoid valve, the fuel supply is insufficient, which causes the engine to drop.
7. The joint of the fuel supply circuit of the fuel system is loose or the pipeline is broken, causing fuel leakage or foreign matter blockage, resulting in insufficient fuel supply. In addition to speed drop, it may also cause flameout.
8. There are many reasons for speed drop, such as incorrect valve clearance, wrong injection timing, damaged turbocharger, faulty brakes, etc.
Having said so many reasons for the speed drop of the excavator engine, what should we do when the speed drop occurs?
The solutions are all here!
1. First, check whether the diesel used in the excavator is deteriorated, whether there are impurities in the oil, and whether the oil circuit is blocked.
2. Check the valve clearance of the excavator engine and the speed of the engine.
3. Check the intake pipeline, clean the air pre-filter and air filter element, and start the engine again.
4. Check whether the speed drop of the excavator occurs when the engine is under load?
5. Carefully check the engine to see if the engine failure causes the speed drop of the excavator engine.
6. In addition, the electronic control, hydraulic system, fuel system, etc. need to be checked.
How do you diagnose a faulty fuel injector in an excavator engine?
To diagnose a faulty fuel injector, listen for any unusual engine noises or misfires. Perform a balance test to identify which injector is causing the problem. Use a diagnostic tool to check for fault codes related to the fuel system. If necessary, remove and inspect the injector for signs of clogging or damage, and replace it if needed.
