Civilian four-meter water meter, gas meter, electricity meter, heat meter. These four kinds of meters are common instruments in the lives of residents and they are also necessary instruments. Whether the installation of the civil four meters meets the standards, whether the readings are accurate and reliable, and whether the use is safe and convenient is related to the interests of the residents' lives. It can be said that only the civilian use of the four tables can not really benefit the people.
With the advent of the "Measurement Law" revised this year, this situation has changed. Article 26 of the "Measurement Law" stipulates that "measurement instruments that fall within the scope of compulsory verification, if they fail to apply for verification in accordance with the regulations or continue to use the test after they pass the test, shall be ordered to stop using the device and may concurrently be fined." Before use, strict inspections must be carried out. Any entity or individual that does not apply for verification or fail to pass the inspection in accordance with regulations shall not use it. The value created by the "Civil Four" plus the "Measurement Method" is obviously greater than the value produced by the four civilian forms alone.
The function of the civilian four-meter plus smart grid smart grid for civilian four-meter is mainly manifested in two aspects. One is the main network intelligence, that is to say, the power grid that controls the civil four-meter must be intelligent, and can use the civil four-table. Conduct timely monitoring. At the same time, the smart grid can perform panoramic diagnosis through the original state, and can perform one-button operation and automatic fault handling through intelligence. To ensure the safety of daily use of residents and automatic processing.
The second is the intelligentization of distribution networks, which is the intelligentization of employees and maintenance personnel who participate in the civil four-meter form. With the cooperation of the smart grid, you can use it as usual, and you can achieve a reasonable allocation of resources. At the same time, you don't need to worry about the maintenance because the smart grid will enter the fault into the network and provide this information to the maintenance personnel in a timely manner. , to reach home without leaving home can make people repair. This facilitates the ease of use of the customer and promotes the mobility of maintenance personnel. It can be said that "1+1" is completely greater than 2.
Under the premise of the Internet of Things and the "Internet +" policy, the civilian four watches can be combined with many strategies to achieve a value of 1 plus 1 and more than 2. At the same time, the development of the civilian four-form table will also begin to focus on how to find a point that can be combined, and hope that in the future there will be a policy that allows 1 plus 1 to be greater than 3.
Daily maintenance of excavator hydraulic cylinders
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.
