How to Prime a Hydraulic Pump: Comprehensive Guide by Kyotechs
In the world of excavators and heavy machinery, the hydraulic pump is a crucial component that ensures efficient operation. Proper maintenance, which includes priming, significantly enhances the pump's longevity and functionality. In this guide, brought to you by Kyotechs, a leader in providing robust solutions for excavator parts since 2009, we delve into the essential steps and tips on how to prime a hydraulic pump correctly.
Introduction
Priming a hydraulic pump is necessary to remove air from the hydraulic system, ensuring smooth and efficient functionality. Air trapped within the system can lead to erratic movements, noise, and even damage over time. With our extensive experience in hydraulic components and systems, Kyotechs offers invaluable insights and products to support your machinery needs.
Why Priming is Important
Properly primed hydraulic systems lead to enhanced operational efficiency. Here’s why priming should be prioritized:
1. Prevents Cavitation: Cavitation occurs when vapor bubbles form and collapse in the liquid, causing damage. Priming prevents such issues.
2. Enhances Performance: With no air pockets, the hydraulic system operates more smoothly and efficiently.
3. Prolongs Equipment Life: Proper maintenance, including priming, can significantly extend the life of your equipment's components.
Step-by-Step Guide to Priming a Hydraulic Pump
1. Preparation
- Safety First: Always prioritize safety. Ensure the machinery is off and adhere to safety protocols.
- Gather Necessary Tools: You’ll need appropriate wrenches, containers for fluid collection, and new hydraulic fluid if necessary.
2. Initial Inspection
- Check Fluid Levels: Ensure the hydraulic reservoir is filled to the appropriate level. Low fluid levels introduce air into the system.
- Inspect for Leaks: Check for any visible leaks in the hydraulic lines that may introduce air into the system.
3. Bleeding the System
- Locate Bleeder Valve: Identify the bleeder valve on your hydraulic pump or associated equipment.
- Loosen the Valve: Use the correct wrench to slowly open the bleeder valve. Air will begin to hiss out.
- Operate the System: Engage the hydraulic system at a low speed to help expel trapped air while collecting escaping fluid in a suitable container.
- Tighten the Valve: Once the fluid flow is consistent and air-free, securely tighten the bleeder valve.
4. System Check
- Recheck Fluid Levels: Refill the reservoir to optimum capacity if needed.
- Test the System: Turn on the machinery and operate it through its full range of motion. Verify that the system runs smoothly with no sporadic movements or unusual noises.
Common Challenges and Troubleshooting
- Persistent Air in System: If air issues persist, consider checking seals and connections for integrity.
- Fluid Contamination: Replace fluid if contamination is suspected, as dirty fluid can introduce new problems.
- Component Failures: Inconsistent priming or ongoing issues might be signs of failing components needing professional inspection or replacement.
FAQs about Priming a Hydraulic Pump
Q1: How often should the hydraulic pump be primed?
A: There isn’t a set frequency for priming; it should be done whenever you notice erratic system behavior or after maintenance tasks that would introduce air.
Q2: Can improper priming damage my hydraulic pump?
A: Yes, if not done correctly, it can lead to cavitation and subsequent pump damage. Following best practices helps prevent such outcomes.
Q3: Do all hydraulic systems require priming?
A: Most do, but the need can vary based on design and operational parameters. Always refer to your machinery's manual.

FAQS
How to test the performance of the excavator's engine?
Testing engine performance includes checking the engine's start-up, running, acceleration, and emissions. Use diagnostic equipment to read engine fault codes, test the fuel system and ignition system, and regularly conduct compression tests and exhaust analysis.
What should be checked when the hydraulic pump has insufficient pressure?
When the pressure is insufficient, check the hydraulic oil level, filter, hydraulic line leakage, pressure relief valve and internal wear of the pump.
What are the common symptoms of hydraulic pump wear?
Symptoms of wear include reduced efficiency, increased noise, leakage, and reduced hydraulic function.
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 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.
