Forced circulation pump

detailed description:

1、 Overview

Our company has developed the FJX type evaporative circulation pump by integrating the advantages of domestic and foreign evaporative circulation pumps. It can be widely used in processes such as evaporation, crystallization, and chemical reactions in industries such as chemical, non-ferrous metallurgy, salt production, and light industry. Its typical application scope is as follows:

*Phosphate fertilizer plant: forced circulation of media for wet process phosphoric acid concentrator and ammonium phosphate slurry concentrator.

*Bayer process alumina plant: forced circulation of sodium aluminate alkali evaporator medium.

*Diaphragm caustic soda plant: forced circulation of caustic soda evaporator medium containing NaCl.

*Vacuum salt production: forced circulation of NaCl crystallization medium.

*Mangnitrate plant: forced circulation of Na2SO4 evaporator medium.

*Wet metallurgical plant: forced circulation of evaporation crystallizer media such as copper sulfate and nickel sulfate.

*Joint alkali plant: Cold precipitation crystallizer in ammonium chloride process, forced circulation of ammonia mother liquor in salt precipitation crystallizer.

*Soda ash plant: ammonium waste liquid recovery process, forced circulation of CaCL2 evaporator medium.

*Paper mill: forced circulation of black liquor concentrator medium.

*Power plants: forced circulation of ammonium sulfate evaporation crystallizer media in flue gas desulfurization, coking plants, and chemical fiber plants.

*Light industry: forced circulation of station media such as alcohol concentration, citric acid evaporation, and sugar evaporation.

Structural Features

*Good anti cavitation performance: suitable for low-level evaporators, significantly reducing investment in evaporation plants. It is also suitable for new evaporators with high fluid resistance heating chambers on the inlet side of the pump (reverse circulation evaporator, dual heating chamber series evaporator).

High pump efficiency and wide high-efficiency zone: By changing the blade installation angle and speed, users' requirements for flow rate and head can be met, and the operating conditions of the pump can be located within the high-efficiency zone of the pump, resulting in significant energy-saving effects.

*Slow type: The pump runs smoothly; The overcurrent components have light wear and long service life; Low degree of crystal damage, suitable for evaporative crystallization process.

*Cantilever rotor: Compared with the double support type, the number of shaft seals is halved, the pump is lightweight, the external dimensions are small, and the maintenance is convenient.

*Pump body center support: Compared with the pump body foot support type, the rotor has better thermal neutrality.

*Rear door structure: The rotor can be extracted without disassembling the inlet and outlet flanges of the pump body, making maintenance convenient and quick.

*Advanced shaft seal: using containerized machine seal, with a lifespan of 6-12 months; Seal with a new type of liquid blocking packing, with a packing life of 3-6 months.

*Evaporator without expansion joint: can be used for elastic pump base or suspended pump, reliable thermal compensation, reducing evaporator investment.

*Good overall reliability: The pump shaft has high strength, the bearing capacity is large, the bearing seat has a water-cooled sleeve, the shaft seal has a long service life, and the material performance is good, ensuring long-term operation of the single pump.

3、 Transmission mode

*Direct connection: The pump and motor are directly connected through a flexible coupling (code D).

*Belt drive: It is easy to adjust the pump performance by changing the speed through a triangular belt drive (code V)

*Reducer: Reduce speed through a gearbox, suitable for high-power pumps (code G)
