How to Test Hydraulic Pump: A Comprehensive Guide
Hydraulic systems are crucial for the functioning of various machinery, and ensuring their optimal performance often hinges on the hydraulic pump. Whether you’re in construction, mining, or any related industry, knowing how to test a hydraulic pump can save you time and resources while maintaining operational efficiency. At Kyotechs, where we have been specializing in excavator parts since 2009, we understand the importance of keeping your equipment up and running. This article will teach you how to test a hydraulic pump, ensuring your machinery performs at its best.
Introduction to Hydraulic Pump Testing
Hydraulic pumps are vital components in hydraulic systems, responsible for converting mechanical energy into hydraulic energy by moving hydraulic fluid. Any malfunction can lead to significant downtime, impacting productivity. Therefore, regular testing and maintenance are critical to identify and resolve issues early. At Kyotechs, our mission has been to support industries by providing High-Quality hydraulic pumps and parts for a wide range of excavators, including renowned brands like Hitachi, Volvo, and Caterpillar.
Steps for Testing a Hydraulic Pump
Testing a hydraulic pump involves several steps. Here’s a guided plan to ensure a thorough examination:
1. Initial Inspection
Begin by visually inspecting the pump for any visible signs of wear, corrosion, or leakages. Check seals, bolts, and connections. At Kyotechs, we offer comprehensive maintenance kits tailored for all significant excavator brands to assist with this process.
2. Check Hydraulic Fluid Levels
Ensure that the hydraulic fluid is at the correct level and is free of contaminants. Dirty fluid can damage the pump, leading to inefficient operation or failure.
3. Measure Pump Pressure
Using a pressure gauge, verify that the pump is operating at the manufacturer’s recommended pressure levels. Kyotechs stocks quality pressure gauges and kits to facilitate this process for excavator models including Sany and Komatsu.
4. Flow Rate Test
Flow meters provide insights into whether the pump delivers hydraulic fluid at the desired flow rate. A drop in flow rate could indicate wear and tear or potential blockages.
5. Listen for Unusual Sounds
A functioning hydraulic pump produces a steady, consistent sound. Listen for any abnormal noises, which might suggest mechanical issues such as cavitation or air entrapment within the system.
6. Temperature Check
Monitor the pump’s temperature during operation. An overheating pump can signify functional inefficiencies that need addressing immediately. Kyotechs’s expert team can guide you in identifying the ideal operational temperature for your equipment.
Common Issues and Troubleshooting
Knowing how to test a hydraulic pump involves recognizing common issues:
- Pump Cavitation: Occurs when there’s an abnormal formation of vapor cavities, indicating a fluid intake problem.
- Internal Leakage: Results from worn-out components or seal failures, noticeable through a drop in pressure.
- Thermal Overload: Overworking the pump can cause overheating, resulting in potential damage.
Our Kyotechs experts recommend regular inspections and using genuine parts to mitigate these issues, ensuring the longevity and reliability of your hydraulic systems.

FAQS
How to check the electrical connection of the hydraulic pump?
The way to check the electrical connection is to visually check whether the connection is loose or damaged, and use a multimeter to test whether the voltage and current are normal.
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.
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.
What is the reason for the cylinder pulling in the excavator engine?
Reasons from the piston group
1. The piston ring gap is too small. If the opening gap, side gap or back gap of the piston ring is too small, the piston ring will be stuck due to heat expansion when the engine is working, and it will be pressed tightly against the cylinder wall, or the piston ring will be broken, which can easily pull out grooves on the cylinder wall.
2. The piston pin is out. Because the piston pin retaining ring is not installed or falls off or breaks, the piston pin will be out during movement, which can easily damage the inner wall of the cylinder and cause the cylinder to blow into the crankcase.
3. The piston cylinder gap is too small or too large. If the piston material is poor, the manufacturing size error is too large, or the piston is deformed after the piston pin is assembled, the matching gap between the piston and the cylinder is too small, and the piston is stuck after heat expansion, which will then damage the cylinder wall.
4. The piston ring is seriously carbonized. Excessive carbon deposits cause the piston ring to stick or bite in the ring groove. At the same time, carbon deposits are a hard abrasive that will grind into longitudinal grooves on the cylinder wall.
5. The piston is seriously off-cylinder. Due to the bending and twisting of the connecting rod, the parallelism and coaxiality deviations of the connecting rod journal, main journal, and piston pin seat are too large, causing the piston to be significantly off-cylinder, which will accelerate the wear of the piston ring, piston and cylinder wall and destroy the formation of the oil film.
Reasons for cylinder sleeves
1. The roundness and cylindricality tolerances of the cylinder sleeves exceed the allowable range, which greatly reduces the sealing of the piston and cylinder sleeves. The high-temperature gas in the cylinder flows down, destroying the oil film between the piston and the cylinder wall, and then causing cylinder pulling.
2. The cylinder sleeve is deformed during the assembly process. For example: the protrusion of the upper end surface of the cylinder sleeve is too large, and the cylinder sleeve is deformed after the cylinder head is installed; the cylinder sleeve water blocking ring is too thick, and the cylinder sleeve is deformed after being pressed into the body, which can easily cause cylinder pulling.
Reasons for use:
1. Whether the size of the cylinder sleeve used during assembly does not match the cylinder body and piston.
2. The air filter is not sealed, which makes the filtering effect worse. Dust, sand and other impurities in the air are sucked into the cylinder, forming abrasive wear. Tests show that if a few grams of dust are sucked in every day, the wear of the cylinder liner will increase by more than 10 times.
What to do if the boom and arm movements are slow?
Check the hydraulic system pressure, inspect control valves and hydraulic cylinders for leaks or wear, clean or replace hydraulic filters, and replace hydraulic oil if necessary.
