Sharing of Use Cases of Shovel Plate Hydraulic Cylinder: Experience and Lessons Learned from Practical Applications
Release Time :
2024-07-03
In the field of engineering machinery, the shovel oil cylinder, as a key power transmission component, its stability and reliability directly affect the operational efficiency and safety of the entire machine. This article aims to provide reference and inspiration for relevant industries by sharing the experience and lessons learned from the practical application of shovel oil cylinders.
1、 Case background
During the mining process of a large mine, a large number of loaders are used for ore loading and transportation. Among them, the shovel plate oil cylinder, as an important component of the loader, is responsible for driving the lifting and tilting of the shovel plate, achieving effective loading of ore. However, in actual use, there were some problems with the shovel oil cylinder, which affected the normal operation of the loader.
2、 Problem phenomenon
After on-site observation and inspection, it was found that the shovel plate oil cylinder has the following problems:
Leakage problem: Some hydraulic oil cylinders of the shovel plate have experienced hydraulic oil leakage after being used for a period of time, resulting in a decrease in oil pressure and affecting the lifting speed of the shovel plate.
Stuck piston rod: In some cases, the piston rod of the shovel oil cylinder may become stuck, unable to retract and retract normally, causing the loader to malfunction.
Seal damage: Due to the harsh working environment, the seal of the shovel oil cylinder is prone to wear and damage, resulting in hydraulic oil leakage and contamination.
3、 Cause analysis
We have conducted in-depth analysis on the above issues and found that the main reasons are as follows:
Hydraulic oil quality does not meet the standard: Some hydraulic oil quality does not meet the standard, containing impurities and moisture, which can easily cause corrosion and wear to the oil cylinder, leading to leakage and damage to the sealing components.
Improper maintenance of the oil cylinder: In daily use, insufficient attention is paid to the maintenance of the shovel plate oil cylinder, and the hydraulic oil is not regularly replaced and the system filter is not cleaned, resulting in oil contamination and internal damage to the oil cylinder.
Improper operation: Some operators operate the loader improperly, such as overloading, violent impact, etc., which leads to excessive pressure on the oil cylinder, accelerating its wear and damage.
4、 Solutions and lessons learned
We have taken the following measures to address the above issues:
Strictly control the quality of hydraulic oil: choose high-quality and genuine hydraulic oil to ensure the cleanliness of the oil and reduce the wear and damage of the oil cylinder.
Strengthen oil cylinder maintenance: Regularly maintain the shovel plate oil cylinder, replace hydraulic oil and clean the system filter screen, and maintain the internal cleanliness and integrity of the oil cylinder.
Standardized operation: Strengthen training and management of operators, standardize operational behavior, avoid improper operations such as overloading and violent impacts, and reduce damage to oil cylinders.
Through the implementation of the above measures, the problem of the shovel oil cylinder has been effectively solved, and the operational efficiency and safety of the loader have been significantly improved. Meanwhile, we have also learned valuable lessons from this case:
Pay attention to the quality of hydraulic oil: Hydraulic oil is the foundation for the normal operation of the shovel oil cylinder, and high-quality genuine hydraulic oil must be selected to ensure the cleanliness of the oil.
Strengthening oil cylinder maintenance: Regular maintenance of the shovel plate oil cylinder is the key to ensuring its stable operation, and it is necessary to strengthen the maintenance and management of the oil cylinder.
Standardized operation: Standardized operation behavior can not only reduce damage to oil cylinders, but also improve the operational efficiency and safety of loaders.
In summary, as an important component of loaders, the stability and reliability of the shovel oil cylinder's performance are crucial for the operation of the entire machine. By implementing measures such as strictly controlling the quality of hydraulic oil, strengthening cylinder maintenance, and standardizing operating behavior, the problems existing in the shovel plate cylinder can be effectively solved, and the operational efficiency and safety of the loader can be improved.
