Product Overview:

1、 Overview of FJX forced circulation pump

FJX evaporative crystallization circulation pump works by utilizing the horizontal thrust generated by the rotation of the impeller along the pump axis, hence it is also known as a horizontal axial flow pump.Mainly used in industries such as diaphragm caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chlorate, sugar production, molten salt production, papermaking, and wastewater for evaporation, concentration, and cooling. To improve equipment production capacity and increase the heat transfer coefficient of heat exchangers for forced circulation. Therefore, it can also be called an axial flow evaporative crystallization circulation pump.

2、 Working principle of FJX axial flow pump

The FJX horizontal axial flow pump does not rely on the centrifugal force of the impeller to transport liquid, but uses the thrust of the rotating impeller blades to make the transported liquid flow along the pump shaft direction. When the pump shaft is driven to rotate by the electric motor, the blades have a certain helix angle with the pump shaft axis, which generates thrust (or lift) on the liquid, pushing it out and discharging it along the discharge pipe. After the liquid is pushed out, a local vacuum is formed at its original position, and the liquid outside will be sucked into the impeller along the inlet pipe under the action of atmospheric pressure. As long as the impeller continues to rotate, the pump can continuously suck in and discharge liquid.

3、 Usage description of FJX forced circulation pump

This series of axial flow pumps can be widely used in processes such as evaporation, crystallization, and chemical reactions in industries such as chemical engineering, non-ferrous metals, 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 liquid evaporator medium.
Diaphragm caustic soda plant: forced circulation of NaCl containing caustic soda liquid evaporator medium.
Vacuum salt production: forced circulation pump for NaCl evaporation crystallizer medium.
Mangnitrate plant: forced circulation pump for Na2SO4 evaporator medium.
Wet metallurgical plant: forced circulation of evaporation crystallizer media such as copper sulfate and nickel sulfate.
Alkali refining plant: ammonium chloride process cold precipitation crystallizer, 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 the medium in the dark night concentrator.
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.

5、 Structural characteristics of FJX forced circulation pump

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 range: By changing the blade installation angle and changing the speed, we can meet the user's requirements for flow rate and head, and achieve energy-saving effects within the pump area of the operating station.
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 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.
Shaft seal: using a containerized machine seal, with a lifespan of 6-12 months; Seal with a new type of liquid blocking packing for 3-6 months.
Evaporator without expansion joint: can be used for elastic pump base or suspended pump, reliable thermal compensation, reducing evaporator investment.
High 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.
