Difficulties in domestic and diplomatic relations have forced transformation and upgrading Recently, some media have linked Microsoft's Nokia plant in Dongguan and some Japanese companies to its production lines in China. The phenomenon is linked with the recent decline in economic data, and pessimistically predicts that "more intensive and large-scale manufacturing collapses." The tide is likely to erupt from January to mid-February 2015."
In January, the manufacturing purchasing managers’ index for the first time fell below the line of weakness in 28 months. The short-term data such as weaker-than-average import and export value decreased by 10.8% year-on-year, indeed reflected the manufacturing difficulties in one aspect, but at the same time, people should not ignore it. The more important economic data contains important signals.
Customs statistics show that in 2014, the export value of China's railway equipment increased by 22.6% year-on-year, and the export of railway technology covered more than 30 countries and regions. The latest data of the Ministry of Industry and Information Technology clearly confirms the pace of transformation and upgrading of China's manufacturing industry: Last year, China eliminated a total of 81 million tons of backward cement capacity; key large and medium-sized enterprises reduced sulfur dioxide emissions by 16%, and smoke and dust emissions fell by 9.1%. At the same time, domestically produced nuclear power steels were used in the world's first third-generation nuclear power project CAP1400, and the added value of electronic information manufacturing industries above designated size was up 12.2% year-on-year.
"The survival of the fittest is precisely the manifestation of normal metabolism of the economic body. Now that China's manufacturing industry is still in a period of transformation, it is indeed more tangled, but the view that 'the collapse of closure' and 'not in 2015' is unavoidable." Dong Dengxin, director of the Institute of Financial and Securities Research at the University of Science and Technology, said in an interview with this reporter.
Improving quality and efficiency are the inevitable way for the development prospects of China's manufacturing industry. Analysts generally believe that the government’s hands are in the hands of the market to promote related industries to improve quality and efficiency, so that “Made in China†can be upgraded to “China-madeâ€. Undoubtedly a bright way out.
In Dong Dengxin's view, the current manufacturing industry in China mainly involves two aspects. One is the overcapacity in some industries and the second is that many companies are still at the low end of the industry chain. To digest excess production capacity and achieve quality improvement and efficiency, we must seek breakthroughs in both the state-owned enterprises and the private sector. “On the one hand, companies that have excess capacity are mostly large-scale state-owned enterprises. This part can achieve quality improvement through voluntary elimination of backward production capacity and asset mergers and acquisitions; on the other hand, the government’s series of simple government decentralization and orientation support measures have made Small and medium-sized private enterprises get benefits, and the creative energy they release will inject fresh blood into China's manufacturing industry,†said Dong Dengxin.
The quality and efficiency of Chinese manufacturing will also be a gradual but clear process. “It needs to be pointed out that there is a lag period from R&D investment to R&D results to capacity conversion, and it takes a while for the market to allocate resources. Therefore, it is not necessary to entanglement with the decline of short-term data. This is also a new normal. Features." Dong Dengxin said.
Experts expect that the slump in China's manufacturing industry will remain for some time, but it is expected that the end of the investigation will begin in one to two years, and a new round of higher quality growth will become one of the pillars of the Chinese economy and even the world economy.
1. Turn off the hydraulic system: Before replacing the hydraulic cylinder, it is necessary to turn off the system to avoid liquid leakage in the hydraulic system.
2. Disassembling the hydraulic cylinder: Disassembling the hydraulic cylinder requires the use of tools such as wrenches, screwdrivers, etc. Firstly, the hydraulic pipeline needs to be removed, and then the bolts of the hydraulic cylinder need to be removed to remove the hydraulic cylinder from the machine.
3. Check the hydraulic cylinder: Check if there is any damage to the hydraulic cylinder, and if there is any damage, replace it.
4. Install a new hydraulic cylinder: Install the new hydraulic cylinder onto the machine and secure the cylinder with bolts.
5. Connect hydraulic pipeline: Connect the hydraulic pipeline to the hydraulic cylinder, pay attention to the position and direction of the connection, and ensure that the connection is secure.
6. Test system: after replacing the hydraulic cylinder, it is necessary to test whether the system operates normally, check whether the hydraulic cylinder operates normally, and deal with any problem in time.
7. Cleaning work: Clean the liquid and debris in the hydraulic system to ensure that the system is clean and avoid any impact on the system.
In the future, not only will China's manufacturing fail to close down, it will also become a pillar of China’s and even the world’s economy with a new look.
