The vertical circulating water pump of wet scrubber is mainly used in the spraying system of the washing tower to lift the liquid in the water tank to the spray layer and spray it evenly on the surface of the packing layer. The vertical circulating water pump can be divided into two types for use in the tank and use outside the tank. The pump head in the tank is beige, which is STH series, and the black pump head outside the tank is STD series. Both pumps can be used with washing towers. If the side of the washing machine contains a water tank design, you can install STH tank pumps. ,save space. If the size of the washing tower is large and no external water tank is designed, the STD series tank pump can be installed. If the tank pump is fixed, a mounting bracket needs to be purchased.
The pump head of the wet scrubber vertical circulating water pump is made of FRPP, PVD and other plastic materials. It can be used for most chemical liquids. It is acid and alkali resistant. It can be used idling and will not be damaged by idling. It is suitable for various acid-resistant liquid circulation. Cooling, spray washing equipment, exhaust gas tower, etching machine, chemical plating, electroless nickel and other special occasions, with dry shaft seal design, which can protect the motor and prevent corrosive gas from entering the bearing and causing damage. It is suitable for vertical installation. It can be used with a filter. The motor link seat can be made of FRPP material to reduce the damage of corrosive gas to the motor and prolong the service life of the motor! The motor surface can be coated with epoxy resin according to customer requirements, and the imprisoned screws can be made of TI material, which is suitable for different workplaces.
Working principle of vertical circulating water pump for wet scrubber
The vertical circulating water pump of wet scrubber is a kind of centrifugal pump, which mainly relies on the centrifugal principle to complete the liquid transportation. Due to the function of the independent impeller structure, the internal pressure can be balanced and the liquid can be completely sealed. The structural feature of the impeller is that the blade is installed next to the impeller, and the opposite blade is on one side with a protruding ring. When it is running, the liquid flowing to the shaft (due to the internal pressure) will be blocked by the back pressure of the protruding ring and the opposing blade.
When the motor is running, the centrifugal force causes the liquid seal to automatically open, forming a state of frictionless points during operation. When the motor stops running, after the centrifugal force disappears, the liquid seal itself elastically springs back to the seal, blocking the rise of the chemical gas, preventing the motor and bearings from being corroded by the chemical gas, and prolonging the service life of the motor and pump.
Product features of vertical circulating water pump for wet scrubber
This machine is made of FRP/PP plastic material for injection molding, which can be used for most chemical liquids, and is acid and alkali resistant.
Suitable for all kinds of acid and alkali circulation, cooling, spray cleaning equipment, waste gas tower, etching machine, chemical plating, electroless nickel and other special occasions
A dry shaft seal is used in the pump, which can be used in idling operation and will not be damaged. The motor end cover has an oil seal design to ensure that acid gas will not easily enter the motor bearing, thereby protecting the motor and prolonging the service life of the motor!
