Recently, Fast developed its own hydraulic retarder and launched the national quadruple weight card to quickly seize the high ground. After supporting 45 heavy-duty tanker trucks of Shaanxi and Ningxia PetroChina natural gas transportation companies, there was another 60 in early March this year. Vehicles equipped with Fast parallel hydraulic retarder and a 10-speed large center-span transmission are used in the Gansu market to be delivered to customers in Gansu.
It is understood that the Fast Reactor has passed the tests of the harsh natural environment, working conditions, and road conditions such as the plateau, high cold, high temperature, and long distances, steep slopes, etc., and the performance indicators are far higher than the entire vehicle. According to the design load, the slope of 6%, the speed of 30 km/h, independent braking for 6 km or 12 minutes†national standard. With advanced design, cost-effectiveness, and high security, it has formed a large-scale, mass-production capacity, and successfully matched domestic trucks and passenger car companies such as Shaanxi Auto, Shengda, Hualing, Yutong, and Jinlong. The braking performance and economy are highly valued by users.
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.
