Excavator Cylinder Piston Rod Seals
Installation and application of piston rod seal for excavator hydraulic cylinder Excavator hydraulic cylinder piston rod seal, hydraulic cylinder piston seal, sealing kit Safe Seal Technology Co., Ltd. , https://www.aprseal.com
The installation and application of hydraulic cylinder piston rod seals in excavators mainly include the following aspects:
1. Applying lubricating oil: Before installing the seal, the surface of the piston rod must be coated with lubricating oil to facilitate the installation and use of the seal.
2. Install the seal: Install the seal on the piston rod in sequence, taking care not to pinch or bend the seal.
3. Pressing the seal: After installing the seal, special tools need to be used to press the seal tightly to ensure its tightness and stability.
4. Check the sealing effect: After installing the sealing element, it is necessary to check the sealing effect. It can be detected by observing the working status of the hydraulic cylinder or using tools such as leak detectors.
5. Application scenario: The piston rod seal of excavator hydraulic cylinder is mainly used in the hydraulic system of construction machinery such as excavators, loaders, and bulldozers to prevent hydraulic oil leakage and ensure the normal operation of the machine.
In summary, the installation and application of hydraulic cylinder piston rod seals in excavators is a very important part of the hydraulic system, and must be strictly operated in accordance with regulations to ensure the normal operation and safety of the machine.
Facing the various problems in the development of the automobile industry and going global, it is now time to formulate a national strategy for China’s auto “going outâ€, revising and improving relevant industrial policies as soon as possible, and actively creating favorable conditions for independent brand enterprises with good product quality and high operating quality. The supporting environment for international development has seized the historical opportunity of rapid industrial development to realize industrial upgrading as soon as possible, to launch the “Chinese car†brand in the world and realize the dream of a powerful automobile country in China. Create an industrial policy environment for starting the "Chinese car" brand.
"Going out" starts the "Chinese car" brand
In fact, a number of self-owned brand companies have begun to voluntarily carry out brand building of “Chinese carsâ€, and the quality of their own brand cars has also been steadily increasing, which has provided the basis for building brands overseas. Great Wall, JAC and other automotive company products have been exported to Asia, Africa, South America, Europe and other countries, and have a large-scale 4S stores, overseas KD factories and overseas joint ventures.
However, due to the impact of the world economic crisis in recent years, the export of self-owned brands has been threatened by local industrial policies, trade protection, and technical barriers, and the continuous appreciation of the renminbi is a new pressure on the export of auto companies. In recent years, one of the problems faced by China’s auto exports is the continuous rise in the exchange rate of the renminbi against the U.S. dollar, which has caused tremendous pressure on auto exporters. Although some products can be digested and absorbed through the improvement of productivity and the formulation of contractual terms, sustained large exchange rate fluctuations make it difficult for exporters to grasp, and can only be released through the rise in the dollar price of exported cars, which ultimately weakens price competitiveness. In addition, as resource prices rise and domestic labor costs increase, exporters face greater pressure on costs. Some companies suggested that the pilot of cross-border trade settlement of RMB should be expanded as soon as possible, and major auto export trading enterprises should be included in the scope of the pilot to cope with the adverse impact of the continuous appreciation of the RMB on export enterprises.
The "Suggestions of the CPC Central Committee on Formulating the Twelfth Five-Year Plan for National Economic and Social Development" put forward: "We must conduct a good research on the overseas investment environment and strengthen the scientific assessment of investment projects. We should improve the ability of comprehensive coordination and improve the inter-departmental coordination mechanism. Implementation of the "going out" strategy of the macro guidance and services; safeguard our country's overseas rights and interests and prevent all kinds of risks." This also provides a basis for the development of China's auto "going out" national strategy.
"OEM" is also the way out for the development of independent brands
In addition to the largest market for new cars, China is also the world’s largest car producer. How to make full use of production capacity and prevent overcapacity is a difficult problem for car companies.
Judging from international experience, OEM is a way out for digesting production capacity. The BMW X3, Mercedes-Benz G, Saab 9-3, Chrysler 300C... These high-end sedans are not unfamiliar, but what is rarely known is that these cars were built by the Magnustel factory in Austria. As the world's third largest component factory, Magnathair has a strong production capacity, but these production capabilities are somewhat overkill for the production of parts and components, so OEM production of cars will become the company's "three production." Even parts and components companies are "enthusiastic" OEM, not to mention car prices, and Mitsubishi, Chrysler, Fiat and other car companies are large OEM.
In fact, independent brands including Chery and Changan are also interested in OEM Subaru and Jaguar Land Rover models. Bentley throws an olive branch to its own brand and has publicly stated that it hopes to find Bentley’s first overseas company outside Crewe, England. Processing factory. Many other high-end brands are also eager to find partners in the country. In the future, OEM may become a pillar business of domestic automobile enterprises.
Technology upgrade is the foundation for the survival of independent brands
After becoming the world's largest automotive market, China's auto industry has stepped into the node of industrial upgrading. How to seize the opportunity of growing market size to achieve industrial upgrading, develop their own core technologies, and become an urgent need to solve the problem of industrial development.
For the independent car companies, the breakthrough of core technology is the real way out for their own brands. After spurt growth in recent years, the domestic automobile industry has gradually established the status of the world's largest automobile manufacturing country, and also provided momentum and conditions for the accelerated development of auto industry independent innovation. Breakthrough in core technology is a top priority. Even if it is a purchased technology, it can also enhance the level of independent brands as a whole. Because blindly playing a price war can increase some sales, the brand will be harmed, and eventually the road will narrower and narrower, and even die. Of course, the improvement of technology brings about an increase in prices. Whether it can be recognized by the market does present certain risks, but this risk must be taken. Some independent brand companies have realized this.
