It has been decades since the introduction and development of submersible pumps. China is already the largest manufacturer of submersible pumps, with low-end and mid-end submersible pumps almost monopolizing the market, and large manufacturers are entering into submersible pumps. The following is a brief list of the development direction of submersible pumps in my country in recent years.
Submersible sewage pumps are mainly developed towards high power, large flow and high lift. From the initial dozens of cubic meters to the current double-suction submersible sewage pump and axial flow pump, the flow rate can reach tens of thousands of cubic meters, and the power has exceeded a thousand orders of magnitude. It has been used in pumping stations and municipal engineering.
Small submersible pumps are mainly developed in the direction of cheapness and corrosion resistance. my country has formed a large-scale production of submersible pumps. QDX submersible pumps, QY submersible pumps, etc. have reached the assembly line operation, and the cost has been reduced to the lowest level. With the provision of living standards, the service life of submersible pumps has become increasingly demanding. In recent years, it has developed rapidly, and there are many materials. Sand casting, precision casting, and stamping have all formed a scale.
High temperature resistant submersible pump is a direction that has just emerged. The submersible pump with circulating water structure is a large category of high temperature resistance before. It mainly achieves the purpose of cooling the motor through external circulating water. At present, the high temperature submersible pump produced by our company can withstand temperature of 100 ℃ without circulating water, and the target is higher temperature. developing.
There are many types of submersible pumps. Each manufacturer combines its own advantages to become better and stronger. After decades of development, I believe that my country will be able to open up its own market in the field of submersible pump manufacturing and break the European monopoly on price.
