1. The sealing of the oil cylinder piston should use products of reliable quality to ensure good sealing performance.
2.Before installing the oil cylinder piston seal, the seal and sealing groove should be cleaned to ensure that the sealing surface is free of impurities.
3. When installing the seal, the correct installation sequence and direction should be carried out according to the drawing requirements to ensure the correct installation of the seal.
4.When installing the seal, special tools should be used to avoid using sharp tools and hard objects to damage the seal.
5. When installing the seal, attention should be paid to whether the seal groove is damaged or worn. If so, it should be replaced or repaired in a timely manner.
6. When installing the seal, an appropriate amount of lubricating oil should be applied to avoid friction damage to the seal during installation.
7.When installing the seal, it should be ensured that the compression of the sealing ring meets the requirements to avoid excessive or insufficient compression leading to seal failure.
8.After installing the seal, a sealing test should be conducted to ensure that the sealing performance meets the requirements.
First of all, we must keep the rules upright——View the development of chemical recycling economy from the policy level
In mid-May, the National Development and Reform Commission (NDRC) and the China Petroleum and Chemical Industry Association held a circular economy exchange conference for the chemical industry. During the event, reporters spoke with government officials and representatives from chemical and petrochemical companies, who expressed two main satisfactions: first, they were impressed by the availability of advanced and practical recycling technologies; second, they gained insights into the national and industry-level policies being developed to support sustainable growth.
The conference organizers provided comprehensive technical data and arranged on-site visits to demonstrate real-world applications of these technologies. While this article will not delve into the technical details, it is worth highlighting the policy framework surrounding the circular economy, which has become a central topic in recent discussions.
The recently approved "11th Five-Year Plan" by the National People's Congress sets clear goals for the development of China’s petroleum and chemical industries. The plan emphasizes reducing energy consumption per unit of GDP by 20%, cutting water use per unit of industrial added value by 30%, and increasing the comprehensive utilization rate of industrial solid waste to 60%. It also calls for a 10% reduction in major pollutant emissions, along with specific targets for innovation, industrial restructuring, resource conservation, environmental protection, and safety production. These measures aim to guide the industry toward sustainable development over the next five years.
Additionally, the China Petroleum and Chemical Industry Association released a draft document titled “Opinions on Accelerating the Development of Circular Economy in the Petroleum and Chemical Industry.†This document outlines key strategies such as optimizing industrial structures, saving resources, controlling pollution, promoting resource recovery, and building support systems for circular economy practices.
At both national and industry levels, several laws and regulations have been introduced to guide the implementation of circular economy initiatives. Examples include the Energy Conservation Law, the State Council’s Interim Provisions on Industrial Structure Adjustment, and the Catalogue of Industrial Structure Adjustment issued by the NDRC.
Despite these efforts, many companies are still in the early stages of adopting circular economy models. While some have made progress, the current policies remain more of a guideline than a binding requirement. Companies and regions that have the capability to implement these practices often do so voluntarily, which means the full potential of the circular economy is not yet realized. To make this transition effective, stronger policy enforcement and clearer regulatory frameworks are essential.
The decision to adopt a circular economy is no longer just a local or corporate choice—it affects the entire nation. With limited natural resources, China faces significant challenges. For example, its total mineral reserves rank fifth globally, but per capita availability is low, with over two-thirds of minerals in short supply. Crude oil and natural gas reserves account for only 2.43% and 1.2% of global totals, respectively. Freshwater resources are also scarce, with per capita availability at just one-fourth of the world average, and consumption accounting for 15% of the global total.
Given these constraints, transitioning to a circular economy—based on the principles of reduce, reuse, and recycle—is not just advisable, but necessary. Companies must act now, rather than delay. Implementing a circular economy requires financial, technological, and material resources, as well as specialized equipment. However, the greatest challenge lies in ensuring consistent and meaningful progress. Only through strong policy and regulatory support can this vision become a reality.
