Delegates exchanged their annual work in 2009 and discussed the revision of the "Interim Measures for the Administration of the National Analysis and Testing Center" and the "Interim Measures for the Administration of the National Large Scientific Instrument Center", as well as the national analytical testing centers and countries during the "12th Five-Year Plan" period. The orientation and development ideas of the large scientific instrument center were thoroughly discussed. Wu Xueti, deputy inspector pointed out in the summary speech of the meeting, pointed out that the National Analysis and Testing Center and the National Large Scientific Instrument Center are important components of China’s scientific research condition system. During the “Twelfth Five-Year Plan†period, we must emancipate our minds and be brave to innovate. While strengthening our own capacity building, we must further promote exchanges and cooperation between the centers, standardize management, and continuously improve the capabilities of each center’s services and support technological innovation and economic development.
The hydraulic cylinder of an excavator is one of the important hydraulic components responsible for driving and controlling mechanical movements. In order to ensure the normal use of hydraulic cylinders and extend their service life, daily maintenance is necessary.
1. Regularly clean the hydraulic cylinder: During use, the hydraulic cylinder will be attacked by various pollutants, such as dust, sediment, oil stains, etc. These pollutants can affect the working efficiency and lifespan of the hydraulic cylinder. Therefore, it is necessary to regularly clean the hydraulic cylinder.
2. Regular inspection of seals: The seals of hydraulic cylinders are key components to ensure their normal operation. If the seals are damaged or worn, it can lead to oil leakage or unstable operation of the hydraulic cylinder. Therefore, it is necessary to regularly inspect the sealing components of the hydraulic cylinder and replace them in a timely manner if there is any damage or wear.
3. Regular inspection of hydraulic oil: The operation of hydraulic cylinders requires the support of hydraulic oil, so the quality of hydraulic oil has an important impact on the working effect of hydraulic cylinders. Regularly check the quality of hydraulic oil, and replace it promptly if there is contamination or deterioration.
4. Regularly check the hydraulic pipeline: The hydraulic pipeline is the blood vessel of the hydraulic cylinder. If there is oil leakage or damage to the pipeline, it can cause the hydraulic cylinder to not work properly. Therefore, it is necessary to regularly inspect the hydraulic pipelines and promptly repair or replace them if there is any oil leakage or damage.
5. Regularly lubricate the hydraulic cylinder: The piston rod and piston ring of the hydraulic cylinder need to be lubricated to reduce wear and friction. Therefore, it is necessary to regularly apply lubricating oil to ensure the normal operation of the hydraulic cylinder.
In short, the daily maintenance of excavator hydraulic cylinders is very important, which can extend their service life and improve work efficiency. Regular cleaning of hydraulic cylinders, inspection of seals, hydraulic oil, hydraulic pipelines, and lubrication of hydraulic cylinders are required.
From March 24th to 26th, the Scientific Research Condition and Finance Department of the Ministry of Science and Technology organized and organized the National Analytical Testing Center and the National Large Scientific Instrument Center Annual Meeting in Shanghai. The deputy inspector Wu Xueti of the Ministry of Finance and Economic Affairs, as well as more than 70 people such as the National Analysis and Test Center and the National Large Scientific Instrument Center, attended the meeting.
