, technical requirements
. The submersible axial flow pump is used to pump rainwater containing a small amount of floating objects in urban rainwater pumping stations and can work normally.
.The water inlet chamber of the submersible axial flow pump is equipped with a tapered water inlet and an anti-vortex facility to ensure an ideal inlet flow pattern at the suction port.
. The submersible axial flow pump can operate normally within the specified range and has stable head flow characteristics. When the pump operates at any point on its characteristic curve, the motor power will not be overloaded.
. All pressure-bearing parts of the submersible axial flow pump are subjected to air pressure tests. The test pressure is times of the design pressure but not less than the test pressure without leakage for a period of time.
. The submersible axial flow pump is carried out after the seal is assembled. There is no leakage during the air pressure test.
. The surface of the submersible axial flow pump is sprayed with anti-corrosion paint and the surface is bright and free of stains, bruises, cracks and other phenomena. After rust and oil removal, the surface of the components is sprayed with epoxy resin anti-corrosion paint
. Submersible axial flow pump The impeller adopts a semi-adjustable structure. The impeller blades and the spherical chamber cooperate with perfect clearance and uniformity. The impeller undergoes a static balance test before assembly. The unbalance amount is within the allowable range and the balance accuracy is .
