Fluorine material pump, as its name implies, is a pump lined with fluorine plastic. According to its structure, it can be generally divided into: fluorine-lined Centrifugal Pump, fluorine-lined Magnetic Pump, and fluorine-lined self-priming pump. The fluorine-lined pump body adopts advanced production technology and is made of metal shell lined with fluorine plastics (F46, F4, etc.), and the load-bearing part of the pump is made of metal material, which has the advantages of high mechanical strength, strong pressure resistance, and superior mechanical impact resistance; The impeller, pump cover, etc. of the main flow components are all made of metal inserts and fluorine plastics covered by one-time high-temperature molding. And acid addition process, electrolyte transportation in non-ferrous metal smelting, pickling process in automobile manufacturing, and pharmaceutical, petroleum, electroplating, dyes, pesticides, paper, food and other industries, long-term under the temperature conditions of -20 ℃ ~ 150 ℃ Transport any concentration of sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant and other strong corrosive media without damage.

Recently, the FAB welding technology of Zhongji Shipbuilding Co., Ltd. passed the physical and chemical test of the welding evaluation module of Zhoushan Quality and Technical Supervision and Inspection Institute, and was approved by ABS Classification Society. It became the only one in China that can also build a large-scale sub-meter without using the plane segmentation line. The segment's shipbuilding enterprise reflects the comprehensive technical capabilities of the company's shipbuilding.
It is reported that the FAB welding process is an advanced technology. It uses the single-sided automatic submerged arc welding machine to achieve double-sided forming effect, and overcomes the outstanding problems of turning over and lifting caused by large-scale segmentation and double-sided welding. . In the past 20 meters of construction of the shipbuilding enterprises, if it is necessary to carry out double-sided welding, it is necessary to introduce a flat-segmented assembly line, or equipped with large-scale lifting equipment, and the cost of supporting equipment is over 100 million yuan.
Since the construction of the 320,000-ton crude oil wheel J0132 ship in 2011, Zhongji Shipbuilding has purchased 10 lower-cost automatic submerged arc welding machines to improve production capacity, save equipment costs and ensure large-scale segmentation. Argument, after half a year of technical exploration by the company's technical backbone, FAB welding technology finally passed the AH36 and EH32 material tests of Zhoushan Quality and Technical Supervision and Inspection Institute, obtained ABS welding evaluation and approved the welding problems of the VLCC ship under construction. This technology replaces the general automatic welding and manual overhead welding hybrid welding operation, which reduces the work intensity, improves the work efficiency and welding quality, and successfully applied in the 20-meter segment construction of J0132 ship, follow-up technical promotion and promotion work. It is also in steady progress.
