Environmental whirlwind has been blowing all over the world, but for the tire industry, time is extraordinarily nervous.
The new tyre labeling law promulgated by the European Union: Since November 1, 2012, tyres for passenger cars, light truck tyres, truck tyres and buses sold in the European Union must be labelled to indicate the tyre's fuel efficiency, rolling noise and wet grip. The grade.
There is no doubt that the new tire labeling method will greatly increase the pressure on the safety and environmental protection of tire enterprises that export to the European Union.
Success is always reserved for those who are prepared. As a leader in the industry, Delta Group Corporation has already shifted its development strategy to energy conservation and environmental protection, taking the path of “low-carbon economy, green manufacturing†and creating a new productivity model for sustainable development of the tire industry.
"We must be willing to protect the environment"
In recent years, the Chinese automobile market has continuously achieved rapid growth. As of the end of 2011, the country’s car ownership has exceeded 100 million. In 2011, China's auto production and sales exceeded 18 million, ranking first in the world.
In the highly developed automotive market, China's tire production also showed a linear upward trend. In 2011, the production of radial tires nationwide reached 393 million. At the same time, China’s tire export volume has been growing at an annual rate, exceeding 130 million units in 2011.
“In the context of economic globalization, energy conservation, safety, and environmental protection are increasingly becoming the core of the global automotive industry revolution.†Ding Yuhua, chairman of the Delta Group Corporation, said at the 2012 Automotive and Tire Industry Summit Forum and Global Business Summit.
As an important high-speed running component of a car, the tire consumes more than 20% of the entire car energy consumption after the car is running, which is second only to the engine.
"Using energy-saving tire products, can bring more than 5% fuel efficiency of the car, which makes the tire an important vehicle for automotive energy-saving emission reduction technology innovation." Ding Yuhua said.
According to the briefing, the Triangle Group has for many years based its coordinated development of economic responsibility, social responsibility and environmental responsibility, and has built a new productivity model for the sustainable development of the tire industry as a breakthrough in corporate transformation and upgrading. And the market has greatly improved. In 2011, Delta Group Corporation still achieved a good performance under the economic downturn both at home and abroad.
Delta Group regards "protecting the earth's green homeland" as the premise and basis for formulating strategic decisions for corporate development. It has invested "green light" in the budget of energy-saving emission reduction projects, implemented clean production, and saved resources and energy.
In 2011, the Triangle Group closed a production line with 34 years of production history, which has attracted the attention of the industry. According to reports, the product line that has been eliminated, its products have a certain market space and profitability at home and abroad, but in order to meet the needs of energy-saving emission reduction and technology upgrades, the company's management has made a decision to close down.
At the same time, they built a high-tech low-carbon green product line. The new production line has obvious energy-saving effects, energy saving is up to 15%, and makes full use of clean energy; digital technology, robot operation, bar code intelligent technology, etc. are used on the manufacturing system to realize the informationization of the whole process of production, inspection and logistics. Control.
With such determination, the Delta Group has invested over 1.5 billion yuan in energy-saving technologies over the past five years, and energy efficiency has maintained a 4% annual increase.
"Standards are very important," and there are no rules that do not qualify.
In the developed countries and regions of the world, compulsory decrees will be implemented to classify tires, with clear definitions on aspects such as fuel economy, energy consumption efficiency and noise, in order to further improve access standards for tire use and promote accelerated Enterprises develop green products.
Efforts to promote and encourage consumer green consumption have become mainstream. China is also accelerating the research and development of standards for the integration of green manufacturing and consumption in order to accelerate the upgrading and upgrading of tire products.
At present, the global economic growth is slowing, and the tire domestic sales market is also slightly pessimistic. These factors will restrict the development of China's tire industry in the medium and long term. In addition, as far as traditional consumption habits are concerned, the peak of auto sales in China in the first half of the year is March, which will gradually decrease or remain unchanged month by month. Some analysts said that it is difficult for China's auto sales growth to break through in April, and this will increase the difficulty of removing rubber inventory in China.
It is not an exaggeration to say that the current situation of China's tire companies can be described in terms of internal and external problems.
"It can be said that after experiencing the test of the economic crisis, automobiles, tires and other manufacturing industries are in a new 'turning point' and a challenging industrial upgrading process." Ding Yuhua said that fundamentally, this is people Reconsidering and positioning the relationship between economic development, human survival and natural environment.
As a chairman unit of the China Tire Industry Technology Innovation Strategic Alliance, the chairman of the China Rubber Industry Association Tire Branch and the chairman of the National Tire Rim Standardization Committee, Delta Group always adheres to the policy of standardization and international integration in the process of industrial development.
In recent years, the Triangle Group has participated in the formulation of 35 national standards. In 2011, the company’s representatives participated in the UN World Vehicle Regulations Harmonization Forum (WP29) held in Geneva and participated in the formulation of the “Global Tire Technical Regulationsâ€. At present, the company is working with relevant agencies of the state to initiate the "green tire industrialization" strategy and jointly research and formulate new tire technical performance standards, testing standards and environmental standards.
Ding Yuhua believes that through the establishment of advanced technology thresholds and access thresholds, we can better promote the continuous improvement of the level of product development and environmental protection.
â‘ Single acting cylinder: only one end of the cylinder has a piston rod. Air is supplied from one side of the piston to generate air pressure. The air pressure pushes the piston to produce thrust to extend and return by spring or self weight.
â‘¡ Double acting cylinder: supply air alternately from both sides of piston, output force in one or two directions.
â‘¢ Rodless cylinder: general term for cylinders without piston rod. There are magnetic cylinder and cable cylinder.
The reciprocating cylinder is called swing cylinder. The inner cavity is divided into two parts by the blade, and the air is supplied to the two cavities alternately. The output shaft swings, and the swing angle is less than 280 °. In addition, there are rotary cylinder, gas-liquid damping cylinder and stepping cylinder.
Compared with the electric actuator, the cylinder can work reliably under harsh conditions, and the operation is simple, and the basic maintenance free can be realized. Cylinder is good at reciprocating linear motion, especially suitable for industrial automation in the most transmission requirements - workpiece linear handling. Moreover, only adjusting the one-way throttle valve installed on both sides of the cylinder can simply achieve stable speed control, which has become the biggest feature and advantage of the cylinder drive system. Therefore, for users without multi-point positioning requirements, most of them prefer to use cylinder from the perspective of convenience. At present, most of the applications of electric actuators in the industrial field require high-precision multi-point positioning, which is the result that it is difficult to achieve with the air cylinder.
The electric actuator is mainly used for rotating and swinging conditions. Its advantage lies in the fast response time and the precise control of speed, position and torque through the feedback system. But when it needs to complete the linear motion, it needs to be transformed by mechanical devices such as toothed belt or screw rod, so the structure is relatively complex, and there are high requirements for the working environment and the professional knowledge of the operation and maintenance personnel.
advantage
(1) The requirement for users is low. The principle and structure of the cylinder are simple, easy to install and maintain, and the requirements for users are not high. Electric cylinder is different, engineering personnel must have certain electrical knowledge, otherwise it is likely to be damaged due to misoperation.
(2) The output force is large. The output force of the cylinder is proportional to the square of the cylinder diameter; The output force of the electric cylinder is related to three factors: cylinder diameter, motor power and screw pitch. The larger the cylinder diameter and power, the smaller the screw pitch, the greater the output force. The theoretical output force of a cylinder with a diameter of 50 mm can reach 2000 n. for the electric cylinder with the same diameter, although the products of different companies are different, they are basically no more than 1000 n. Obviously, the cylinder has more advantages in terms of output force.
(3) Strong adaptability. The cylinder can work normally in high and low temperature environment, and has the ability of dustproof and waterproof, which can adapt to all kinds of harsh environment. Because of a large number of electrical components, the electric cylinder has high requirements for the environment and poor adaptability.
