Since the reform and opening up, China's pump and valve industry has achieved a well-deserved development, its overall strength has been significantly enhanced, and its international competitiveness has also been significantly improved. However, China's pump and valve industry is still in a disadvantageous position in the field of high-end pump and valve products. Before foreign well-known pump and valve enterprises with strong research and development capabilities and innovation capabilities, domestic companies may find it hard to see what they want. What are the reasons behind the impediment to the localization of high-end products in the pump and valve industry? CNPV China Pump Valve Network Industry Alliance (CHINAPUMPVALVENETWORKINDUSTRYALLIANCE) made a detailed analysis of this situation and pointed out that it is not difficult to see from the “2012-2016 China Valve and Coil Manufacturing Development Prospects and Investment Forecast Analysis Reportâ€. Since 2012, the localization of high-end valves has become very difficult. According to the data provided by the China General Machinery Industry Association and the study on the domestic import and export of pump products in 2014, the CNPV consortium has reached the following conclusion: Since 2014, China's imports of larger pump products mainly include: Hydraulic reciprocating Plunger pumps, other hydraulic reciprocating discharge pumps, rotary axial piston pumps, other centrifugal pumps with speeds below 10,000 rpm, liquid pump parts, vacuum pumps, etc. Valve products include: pressure relief valves, hydraulic transmission valves, pneumatic transmission valves, safety valves or relief valves, valve parts and so on. These valve products occupy a considerable proportion in China's high-end products, showing that China's dependence on imported valve products is very strong. According to analysts at the CNPV Coalition for Economics and Production, there are four main reasons that hinder the smooth development of China's high-end pump valves: First, the investment in innovative R&D capital is obviously insufficient. According to the incomplete statistics of the pump industry, investment in R&D capital accounted for less than 2% of the company's main operating revenue, and the investment in R&D for the valve industry was similar. Without funding as a backing and guarantee, how about innovation and R&D? Second, the capacity for independent innovation is weak. Most of the domestic pump and valve companies are mainly SMEs. They have no ability to carry out independent innovation and R&D. The company's focus is also on low-end, low-margin products, and a serious lack of independent innovation awareness and capabilities. Third, customers have low recognition of domestic high-end pump and valve products. Due to many problems in marketing concepts and narrow sales channels of domestic pump companies, many customers hold an unappreciated attitude towards domestic high-end pump valves, which directly leads to poor customer willingness to purchase domestic products. Fourth, the lack of industry common technology research. As a result of restructuring, some research institutes facing industry services have become companies that are fighting for each other. The nature of the structure and the focus of their work have changed greatly, and their technical support has also weakened. At this stage, our country's pump and valve companies want to make breakthroughs in independent innovation, we must be targeted, stable and steady, and gradually gain market position.

A lemon yellow to brown powder. The relative density is 2.44 ~ 3.60. Melting point 350 ~ 400 ℃. Insoluble in water, alcohol and acid. The fine powder is a crystalline iron oxide hydrate. Due to the different production methods and operating conditions, the degree of hydration is different, and the crystal structure and physical properties are very different. Good coloring power, covering power, light resistance, acid resistance, alkali resistance and heat resistance. Crystal water is decomposed above 150 ℃, and most of it turns red above 400 ℃.
