Recently, Fangtian Pump Co., Ltd., Jilin City, developed its own high-efficiency aquaculture wells with submersible pumps through the provincial identification of new products. In order to get rid of the defects of easy corrosion, high power consumption and short service life of submersible pump products used in traditional seawater breeding wells, Fangtian Pump Co., Ltd. actively organized the relevant technical personnel to tackle this problem and focused their efforts on the development of technology that is also corrosive After repeated tests to determine the use of sintered silicon steel process, so that the products of similar products of seawater corrosion resistance was significantly enhanced, the continuous operation of up to 6-8 months, up more than 4 times the running time of similar products, and have more Good energy-saving effect, each pump can save up to 8000 degrees. In order to promote the technical establishment of the product and speed up the production up to efficiency, the municipal economic commission actively organized the relevant personnel to conduct in-depth review of the application materials and related documents by Fangtian Company, and actively negotiated with the relevant departments of the province.
