How to Choose the Appropriate Hydraulic Oil for Excavators?
Choosing the correct hydraulic fluid is vital for the efficient operation and longevity of construction machinery like excavators. Here are some key considerations for selecting the right hydraulic oil for various types of excavators:
Understanding Hydraulic Fluid Classification:
Hydraulic fluids are classified based on application, oil properties, and quality levels. When selecting a hydraulic fluid, consider the excavator’s working environment and operating conditions. For example, if the excavator works in harsh conditions, you will need a hydraulic fluid with appropriate viscosity and oxidation resistance.
Compatibility with Engine and Hydraulic Pump:
Ensure that the hydraulic fluid is compatible with the excavator’s engine and hydraulic pump. Proper matching is essential for the efficient operation of the entire system, including load adaptability and high transmission efficiency throughout the engine speed range.
Quality of Hydraulic Fluid:
The quality of the hydraulic fluid is crucial, especially under the harsh conditions typical of construction machinery operations. Choose a hydraulic fluid that meets the required viscosity, oxidation resistance, and other quality criteria to protect equipment, enhance efficiency, and extend its lifespan.
Selection Principles and Requirements:
Consider the viscosity, oxidation resistance, and filtration properties of the hydraulic fluid. Especially when dealing with complex geological conditions or specific working environments, selecting the right hydraulic oil becomes even more critical.
By thoroughly analyzing the excavator’s working environment and conditions, and understanding the characteristics and standards of hydraulic oils, you can make a well-informed choice that ensures optimal performance and longevity of the machinery.
How To Add Hydraulic Fluid To Excavator?
Adding hydraulic fluid to an excavator involves several crucial steps and precautions to ensure the hydraulic system operates efficiently and to extend the lifespan of the machinery. Here’s a comprehensive guide:
Selecting the Appropriate Hydraulic Oil:
Choose the right hydraulic oil based on the excavator’s working conditions and the specific requirements of its hydraulic system. Hydraulic fluid plays a key role in energy transfer, lubrication, sealing, and cooling. The selection should consider compatibility with the materials, seals, coatings, and paints used in the hydraulic components.
Using an Automatic Oiler:
To prevent dirt and water from entering the hydraulic and lubrication systems, consider using an automatic oiler. This tool facilitates the addition of hydraulic fluid by adjusting the height and pump drive, reducing labor intensity and enhancing operational ease.
Filtration and Purification:
Before adding hydraulic oil, use advanced filtration and purification methods to remove contaminants. This helps maintain the cleanliness of the hydraulic system, which is crucial for prolonging the life of the machinery. Ensure the hydraulic tank is designed with oil absorption and return filter elements to maintain oil purity.
Replacing the Hydraulic Oil Filter:
Traditionally, replacing hydraulic oil involves draining the oil from the tank, changing the hydraulic oil filter, and refilling with new oil. However, this method replaces only about 48% of the oil, leaving dirty oil in the system. This can reduce the service life of hydraulic components, so thorough replacement procedures should be considered.
Maintenance and Monitoring:
Regularly check and maintain the hydraulic oil to ensure it meets performance requirements. Monitor for changes in oil quality and replace aged or deteriorated hydraulic oil promptly to prevent damage to the hydraulic system.
Controlling Oil Cleanliness:
Ensure oil cleanliness by controlling contaminants, reducing residues, and selecting proper oil filters. Maintaining oil cleanliness is critical to reducing the probability of system failures.
Considering Environmental Factors:
Since excavators are often used in varying environmental conditions, it’s important to select hydraulic oil that can withstand changes in temperature and other environmental factors. This ensures reliable performance under diverse working conditions.
In summary, adding hydraulic fluid to an excavator requires careful consideration of multiple factors. By selecting the appropriate hydraulic oil, using an automatic oiler, ensuring thorough filtration and purification, replacing filters correctly, maintaining the system regularly, and considering environmental impacts, you can ensure the excavator’s hydraulic system operates smoothly and prolong the machine’s lifespan.
