How to choose the circulating water pump for spray tower? -Acid and alkali resistant vertical pumps

　　Circulating water pump for spray tower is used for circulating, conveying and lifting all kinds of acid and alkali liquid on the spray tower, spray tower is also called spray device, spray device is composed of tower body, packing, liquid distributor, air-water separator, spray system, circulating water pump, circulating pool, liquid storage and feeding system, spray tower circulating water pump is used in the whole spray process.

　　Shower tower circulating water pump how to select

　　Spray tower circulating water pump can be divided into acid and alkali tank pumps and acid and alkali tank vertical pumps, Schaederbauer spray tower circulating water pump according to the material can be divided into PP vertical pumps, fluorine plastic vertical pumps, suitable for conveying a certain concentration of strong acids, alkalis, salts, oxidizing agents, and other corrosive mediums, suitable for coating pretreatment, PP spray tower, electrophoresis cycle, and so on.

　　1, to determine the spray tower pump material

　　According to the type of media, temperature, concentration to determine the pump material: customer site water is mainly: acid and alkali neutralization of liquid (PH: 9); temperature of 35 ℃ room temperature, the main medium for the 35% sodium hydroxide;

　　According to the medium PH acidity and alkalinity, temperature and concentration, we recommend the customer spray tower pump material selection: FRPP.

　　2, to determine the power of the spray tower pump

　　4KW below the spray tower with circulating water pump is recommended to use the tank vertical pump, 4KW above the spray tower circulating water pump is recommended to use the tank outside the vertical pump, do special placement of chemical pumps shelf, do not place the tank, because 4KW above the spray tower circulating water pump vibration in operation, over time, easy to the tank and the washing tower of the welded joints vibration de-welded, resulting in liquid leakage.

　　3、Determine the specific model

　　According to the customer's other requirements to determine the specific model: the combination of materials, power, technology, pumps to achieve sustainable idling, vertical installation outside the tank with rain cover requirements, customized.

　　SHIDEBAO spray tower circulating vertical pump features:

　　1、The pump body is made of FRPP and PVDF, which has the characteristics of high temperature and corrosion resistance.

　　2, complete models, according to the installation of different ways, you can choose to install outside the tank or tank installation of the pump, power from 0.75 ~ 22.5KW, full flow 14.4m ³ ~ 300m ³, full head 8 ~ 40m, to meet your various needs.

　　3、Applicable to etching and cleaning equipment, exhaust gas scrubber tower, cooling cycle and use with filter.

　　4, selection of professional, spray tower pump flow for the number of nozzles multiplied by the nozzle flow, commonly used spiral 4 points nozzle, flow rate of 1 cubic meters per hour, 6 points nozzle, 3 cubic meters per hour, 1 inch nozzle, 5 cubic meters per hour, in order to achieve better atomization effect, the head will be height plus 10 meters.

　　5, used in high corrosive liquid and environment, it is recommended to purchase another titanium screws, motor another purchase by the epoxy resin coating treatment.
