Application of Axial flow Pump Double End Face Mechanical Seal in Caustic Soda
As we all know, forced circulation axial flow pump is one of the key equipment of the three-effect countercurrent evaporation caustic soda plant, which relates to the normal operation of the whole plant.There are three sets of three- The axial flow pump of the two kinds of performance adopts double-end mechanical seal structure, so far, the three axial-flow pumps have been running continuously for four months without any mechanical seal leakage and the normal and reliable operation. The results show that double-end mechanical seal is feasible in caustic soda evaporation forced circulation axial-flow pump and can be used as seal reference for other caustic soda pumps. The process requires that each evaporator be equipped with an axial flow pump and the lye is circulated through an axial flow pump as shown in Figure 1. The lye is fed from the pump inlet circulation pipe 8 into the axial flow pump 5 through the pump impeller, The outlet circulation pipe 4 flows into the inner circulation pipe of the heater 3 and the heated and heated lye flows into the evaporation tank 1 through the distributor 2. The evaporated lye is introduced into the collector 9 from the outer circulation pipe of the heater 3 , And then through the circulation tube 8 and then into the axial flow pump cycle.Figure 6 in the axial flow pump for the double-end mechanical seal parts, its reliability directly affects the operation of the device. Axial flow pump working conditions of the mechanical seal Effect is very influential.
