In recent years, by the domestic good investment environment and the deepening of infrastructure policies, China's valve industry will usher in the continued growth of new opportunities for development. Enterprises continue to self-innovation, the achievements of the leading technology, a wide range of products dizzying, showing a thriving development prospects. It is precisely because of such technological achievements, which makes the valve instrumentation industry can always maintain a positive upward trend. In the "12th Five-Year Plan", the central government has emphasized the strategy of localization of major equipment manufacturing industry, strived to make major projects in key projects in the short term and localization of key valves to achieve localization or partialization so that China's valve manufacturing industry will be at the forefront of the world. This brings a golden opportunity for valve manufacturing.
　
In 2013, the development of the valve has a long way to go and should be constantly striving for continuous efforts to increase the reliability, applicability and performance of domestic products. Believe that under the correct leadership of our party, through our unremitting efforts, China-made machinery and electronic products will surely have stronger international competitiveness so that China's manufacturing will become China's creation. First of all, the pump test run should meet the following requirements: ①drive the steering should be the same with the pump steering; ② identify the pipeline pump and coaxial pump steering; ③ fixed connections should be no loose, Lubricants specifications and quantity should be consistent with the provisions of equipment and technical documents; ④ pre-lubrication requirements of the site should be pre-lubricated; ⑤ all instrumentation, safety devices should be sensitive, accurate and reliable; ⑥ crank should be flexible, No abnormalities; ⑦ high temperature pump should be preheated before the test run, the temperature should be uniform rise, the temperature rise per hour should not exceed 50 ℃; pump body surface with a working medium import process pipe temperature difference should not exceed 40 ℃; ⑧ set to eliminate the impact of temperature rise of the connection device, set the bypass connection device to provide cooling water.
　　
Second, the fluorine plastic centrifugal pump should pay attention to the following points: ①prohibit water-free operation, do not adjust the suction port to reduce the displacement, prohibit the operation of the flow is too low; ② monitoring operation, completely prevent packing box leakage, replacement Fill the box with a new filler; ③ to ensure that the mechanical seal flush water, water-cooled bearings prohibit the use of excessive water flow; ④ do not use too much lubricant; ⑤ inspection according to the recommended cycle. Establish operating records including operating hours, packing adjustments and replacements, adding lubricants and other maintenance measures and times. Record and record pump suction and discharge pressures, flow rate, input power, temperature of wash fluid and bearings, and vibration conditions on a regular basis. ⑥ pump host is relying on the atmospheric pressure will be low water pumping to a height, while the atmospheric pressure can only support about 10.3m of water column, so the pump host to leave the water 12 meters can not work.
Fluoroplastic centrifugal pump operation precautions
With the valve industry to accelerate the pace of restructuring, the future competition between the valve industry enterprises will be the valve between the product quality and safety and product brand competition, the product to high-tech, high-parameter, resistant to corrosion, high Life direction. Domestic valve manufacturing industry in a huge demand environment, will also show a better development prospects.
