Abstract

The invention discloses a single-stage double-suction horizontal self-sucking pump, and aims at providing a single-stage double-suction horizontal self-sucking pump achieving high flow, high efficiency and zero leakage. The single-stage double-suction horizontal self-sucking pump comprises a pump case. A pump case through hole is formed in the pump case. A rotating shaft is mounted in the pump case through hole. A pump case cavity is arranged in the pump case. An impeller is fixed to the rotating shaft. Mechanical seal assemblies are fixed to the outer side face of the pump case and arranged at the two ends of the pump case through hole. A first bearing body assembly is fixed to one mechanical seal assembly, and a second bearing body assembly is fixed to the other mechanical seal assembly.An inlet pipeline is arranged on one side of the pump case, and a chamber is arranged on the other side of the pump case. The single-stage double-suction horizontal self-sucking pump has the beneficial effects that the double-suction impeller is adopted, axial force is low, the cavitation performance is improved, and the displacement of a pump head is increased; mechanical seal is adopted, performance is stable, and no leakage happens; and a reducer is adopted for butt joint, hydraulic losses are reduced, and the energy utilization rate is increased.

Description

technical field [0001] The invention relates to the related technical field of pipeline centrifugal pumps, in particular to a single-stage double-suction horizontal self-priming pump. Background technique [0002] There are two types of existing self-priming pumps, horizontal and vertical, both of which use single-stage single-suction impellers; horizontal self-priming pumps have small flow, low efficiency, and large axial force, making it difficult to balance; vertical self-priming pump rotors The design of direct connection with the motor leads to large rotor jump, which is easy to damage the sealing ring and impeller, and the replacement of the rotor is complicated. The auxiliary impeller used for the rotor seal will leak when the pump is started and stopped, affecting the site environment. SUMMARY OF THE INVENTION [0003] The invention provides a single-stage double-suction horizontal self-priming pump with large flow, high efficiency and zero leakage in order to over...
