Hazardous chemicals are highly toxic chemicals and other chemicals that are toxic, corrosive, explosive, combustible, and flammable, and that are harmful to humans, facilities, and the environment. According to the relevant management measures, the inspection and quarantine department will mainly conduct conformity inspections on the classification, labelling, and safety data sheets for import and export of dangerous goods. Imported dangerous chemicals may also require the use of Chinese labels; inspections that are not qualified will not be allowed to import and export. .
In order to ensure the smooth import and export of dangerous chemicals, the inspection and quarantine department reminds relevant import and export companies to provide inspection materials such as dangerous characteristic classification identification reports, Chinese safety data sheets and dangerous publicity labels according to regulations. At the same time, we should actively study the latest relevant provisions of the GHS knowledge and hazardous chemicals management at home and abroad, master the classification of chemicals, label review and production of safety data sheets; and collect and understand the requirements of importing countries for hazardous chemicals, such as exports to the European Union Should be familiar with the EU CLP regulations, etc. to ensure that the product meets the requirements of the importing country.
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.
On November 18th, 2011, the inspection and quarantine authorities learned that according to the "Regulations on the Administration of Dangerous Chemicals Safety" to be implemented soon, on December 1st this year, the inspection and quarantine authorities will inspect the import and export of dangerous chemicals and packaging without inspection or Unqualified hazardous chemicals will not be allowed to be imported or exported. Related companies should pay close attention to this.
