When the pump shaft is driven by the motor to rotate, because the blade has a certain helix angle with the axis of the pump shaft, a thrust (or lift) is generated on the liquid, and the liquid is pushed out and discharged along the discharge pipe. When the liquid is pushed out, a partial vacuum is formed at the 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 keeps rotating, the pump can continuously suck in and discharge liquid. The forced circulation pump works by using the horizontal thrust along the direction of the pump axis generated by the rotation of the impeller, so it is also called a horizontal axial flow pump. Mainly used in the evaporation of diaphragm method caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chlorate, sugar, molten salt, paper, waste water and other industries. Concentration and cooling, in order to improve the production capacity of the equipment, increase the heat transfer coefficient of the heat exchanger for forced circulation. Therefore, it can also be called an axial flow evaporative circulation pump.

range ofdifferent designs possible. Fast, intensive and uniform heating ofthe screw
barrel section is ensured by electrical heaters. The barrel sections are cooled with
water, by means ofan internal bore system, with bores arranged close to the inside
barrel wall.
Closed barrel section
Barrel section with opening for material feed or for devolatilization
The processing section is provided with stainless steel plates as a protection against
accidental contact.
Screw Elements: High-speed steel W6Mo5Cr4V2,nitrogen treatment.
Screw Shaft:Â High performance alloy steels,40CrNiMoA; with standing high load,Etc
Â
The inter meshing screws co-rotate and wipe each other with narrow clearance so that
no residues are left in the screw flight and clean effort is thus reduce.
Screw elements with various pitches and lengths
Kneading blocks with various angles ofstagger, numbers ofkneading disks and disk
widths.
Screw tips to fix the screw set axially
Gear teeth connection to ensure power flow between the screw shaft and screw
elements.
Reducing and distributing gearbox
(include shaft coupling)
1 set TSE-75
The gearbox reduces the motor speed to the speed ofthe screw shafts and
distributes it to the two output shafts. Screw torque is 1050 N.m per shaft
The gearbox consists of:
Involute gear teeth couplings between the output shafts and screw shafts
Integrated thrust bearing assembly, radial bearings ofthe output axis are NSK products
Bottom part ofcasing designed as oil sump
1. Screw components designed by computer aids is kneading type, has excellent self-cleaning function, the new kneading block design effectively avoid the problems of overheating and energy consumption.
2. According to process system and formula requirements, the unit can optimize its L/D ratio, barrel structure, screw array, venting number and location, feeding method, electrical control methods etc. For rational allocation.
Package: Wooden case or Using Anti-rust oil processing, then use stretch film cover extruder against moisture damage.
