Stability of Drainage axial flow pump

Drainage Axial flow pump running stability, is the general pump can not be compared.
⑴ single-stage high, single-stage pump shell height is short, shortening the height of the machine to increase the stability of the operation.
⑵ pump shaft diameter is much larger than the national standard diameter, for the extraction of super deep underground groundwater source to increase the safety factor.
⑶ castings using HT200 super deep well pump shell with ductile iron or cast steel to improve the pump casing pressure coefficient.
⑷ check valve with a unique design, from the fundamental to avoid the super deep well submersible pump due to stop the pump when the impact of water hammer is too large caused by the body of the broken body defects.
⑸ small axial force, an increase of the motor life, improve the efficiency of the unit.
