How a Hydraulic Pump Works: A Comprehensive Guide
In the world of heavy machinery, understanding the intricacies of components like hydraulic pumps can lead to better maintenance, longer life spans, and improved performance. As a leading supplier of excavator parts, Kyotechs is dedicated to ensuring our customers have all the information they need about pivotal components such as hydraulic pumps.
Introduction to Hydraulic Pumps in Excavators
Hydraulic systems are the backbone of modern machinery. Highly efficient and potent, they transform mechanical energy into hydraulic energy, which is then harnessed to perform work. At the heart of these systems is the hydraulic pump, a component critical to the functionality of excavators from brands like Hitachi, Sany, and Volvo.
What is a Hydraulic Pump?
A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. It generates a flow of hydraulic fluid that can be used to do work by circulating the fluid under pressure to other hydraulic components, such as motors and cylinders. This capability makes hydraulic pumps indispensable in operating machinery like excavators.
How Does a Hydraulic Pump Work?
To fully grasp how a hydraulic pump works, we need to explore its core components and functions:
1. Intake: The pump draws hydraulic fluid from a reservoir into the pump chamber through the suction port. This is facilitated by the movement of rotating or reciprocating parts inside the pump.
2. Compression: As the pump operates, it compresses this fluid, generating hydraulic pressure. This pressure is achieved by either a decrease in the volume within the pump chamber or the use of pistons and vanes.
3. Discharge: Finally, the fluid is released at high pressure through the discharge port. This pressurized fluid is what drives hydraulic motors, cylinders, and other systems.
Types of Hydraulic Pumps
There are several types of hydraulic pumps, each designed for specific functions and performance characteristics:
- Gear Pumps: Utilized for their simplicity and reliability, these are often found in systems with low-pressure requirements.
- Piston Pumps: Known for high efficiency and pressure capabilities, piston pumps are ideal for heavy-duty applications.
- Vane Pumps: Often used in mid-range pressure systems, vane pumps offer balanced efficiency and performance.
Benefits of Hydraulic Pumps in Excavators
- Efficiency: Hydraulic pumps are highly efficient, as they deliver consistent power with minimal losses.
- Control: These pumps allow for precise control over excavator movements, providing operators with accuracy in tasks.
- Durability: Designed to withstand tough working conditions, hydraulic pumps are built for long-lasting service.
FAQ: Hydraulic Pump Insights
1. What role does a hydraulic pump play in an excavator?
A hydraulic pump serves as the power source for moving the components of an excavator, enabling it to lift, dig, and move materials with ease.
2. Can regular maintenance extend the life of a hydraulic pump?
Yes, regular maintenance, including checking for leaks, monitoring fluid levels, and replacing worn-out components, can significantly extend the lifespan of a hydraulic pump.
3. How do hydraulic pumps contribute to energy savings?
By efficiently converting mechanical power into hydraulic energy, pumps reduce the overall energy consumption of an excavator.
4. What signs indicate a failing hydraulic pump?
Common signs include unusual noises, decreased performance, overheating, and fluid leaks.

FAQS
Why do you need to check and replace the engine belt regularly?
Regularly checking and replacing the engine belt can prevent the belt from breaking and ensure the normal operation of the engine.
What to do if the excavator has difficulty starting?
Check the battery charge and connections, inspect the starter motor and ignition system, ensure the fuel system is supplying fuel properly, and read fault codes for further diagnostics.
How to check if the hydraulic system of a track excavator is functioning properly?
To check if the hydraulic system is functioning properly, observe the color and viscosity of the hydraulic oil, check the oil level in the hydraulic tank, look for leaks in the lines and fittings, and test the output pressure of the hydraulic pump.
How should Kobelco excavators be maintained in high temperatures in summer?
Kobelco excavator maintenance tips 1: Cooling to prevent air blockage In high temperatures in summer, the engine is prone to air blockage due to high speed and difficult heat dissipation, which makes it difficult to start the engine after stopping for a few minutes. Once air blockage occurs, the excavator driver should stop the engine immediately to cool down and eliminate the fault.
Kobelco excavator maintenance tips 2: Observe the water temperature gauge at any time to prevent water shortage When driving in high temperature weather, always pay attention to checking the cooling water volume and the water temperature gauge. When water shortage is found, immediately idle the engine to cool down before adding water, and be careful not to open the radiator cap immediately to prevent burns.
Kobelco excavator maintenance tips 3: Prevent engine oil from deterioration Lubricating oil is easily diluted by heat, resulting in poor oxidation resistance, easy deterioration, and even causing faults such as burning of the bearing and the shaft. Therefore, the crankcase and gearbox should be replaced with summer lubricating oil, and the amount and quality of the lubricating oil should be checked frequently, and replaced in time.
Kobelco excavator summer maintenance tips 4: timely cleaning of engine surface oil If the external oil of the engine is too thick, it will affect the heat dissipation and bury the hidden danger of failure of various parts. You can use the high-pressure spray method to clean the engine parts with a cleaning agent that does not corrode the body parts.
Kobelco excavator summer maintenance tips 5: prevent the water tank water temperature from being too high In summer, the cooling water of Kobelco excavators evaporates and consumes quickly. You must add enough cooling water before leaving the vehicle, and check the water level frequently during work. For single-cylinder diesel engines without a water temperature gauge, always pay attention to the red mark height of the water tank float. If the float cannot be used normally, it should be repaired in time. If the boiling phenomenon occurs during work, do not add cooling water directly. Stop the work, slow down the generator, and slowly add cooling water after the water temperature drops to avoid cracks in the water tank when it is cold.
Kobelco excavator summer maintenance tips 6: Ensure the best oil supply time In summer, the oil supply time of Kobelco excavators should be adjusted. If the oil is supplied too early, the engine will make a knocking sound and sometimes reverse; the oil supply time should not be too late, otherwise the engine will work weakly.
How to charge a new battery for the first time?
After the newly purchased battery is injected with the liquid with the appropriate specific gravity, it should be placed for 6-8 hours to allow the liquid to penetrate the plates. When the temperature of the liquid drops below 30℃, it can be charged for the first time. The initial charge should be carried out in two stages. The charging current in the first stage should be lower than 1/10 (one tenth) of the rated capacity of the battery, and the time is about 25-35 hours. When the voltage of a single cell rises to 2.4 volts, the current is reduced by half and the second stage is entered, which takes about 20-30 hours. When the electrolyte emits strong bubbles and the specific gravity no longer rises, the voltage of a single cell rises to 2.6-2.75 volts and remains unchanged for 2-3 hours, it means that the battery is fully charged. During charging, the temperature of the electrolyte will rise, exceeding 40℃ in summer and 35℃ in winter. Charging should be suspended and recharged when the temperature drops below 30℃ to prevent damage to the plates and separators.
