Description
Technical field
The utility model relates to centrifugal pump, is specially in a kind of single-stage double-suction and drives centrifugal pump.
Background technique
Double suction pump is widely used in the medium of carrying clear water or being similar to clear water.In the existing technology, double suction pump adopts horizontal middle open type pump body structure, single-stage double-suction receded disk impeller, and its suction port and exhaust port are positioned on the same center line, and level sucks, discharges medium, and motor can be arranged on the left side or the right side of pump as required.But because of runner adopts trapezoidal runner, volume is big, and bearing two end supports spacing is long, and same rotor part is not reversible, and axle contacts with medium, and is not corrosion-resistant, so operation maintenance is inconvenient.
The model utility content
The technical problem that the utility model solved is to provide drives centrifugal pump in a kind of single-stage double-suction, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
Drive centrifugal pump in the single-stage double-suction; Comprise the pump housing, pump cover, rotor part dress and impeller, said pump cover removably is fixed on the said pump housing, is running through the said rotor part dress that can oppositely install in the said pump housing; Said rotor part is loaded onto and is provided with impeller and said impeller is positioned at the said pump housing; The additional line system also is installed on the said pump housing, and an end of said rotor part dress is provided with coupling portion dress, and the rotor part of the outer both sides of the said pump housing is loaded onto and is connected with fore bearing portion dress and bearing portion dress respectively; Said fore bearing portion dress and said coupling portion dress are positioned at the same side of the said pump housing, are provided with casing ring between said pump cover inside and the impeller.
In the utility model, said fore bearing portion dress is fixed on the said pump housing through stud bolt and headkerchief nut.Said bearing portion dress is fixed on the said pump housing through stud bolt and headkerchief nut.Be provided with runner in the said pump housing, said runner is a rectangularl runner.Said rotor part dress does not contact with medium for hermetically sealed axle.
In the utility model, the conventional trapezoidal runner changes rectangularl runner into, has shortened bearing two end supports spacing; Increased the rigidity of rotor part dress, and adopted no worm structure to make the same rotor part dress can be reverse, the rotor part dress seals fully; Do not contact with medium, thus corrosion-resistant.
Beneficial effect
The utility model volume is little, and the rotor part dress is fixed in the pump housing, and shockproof effect is good, and axle is corrosion-resistant, and pump cover can be dismantled, and makes that repair demolition is convenient, seal ring easy mounting location.And in the utility model, the conventional trapezoidal runner changes rectangularl runner into, has shortened bearing two end supports spacing; Increased the rigidity of rotor part dress, and adopted no worm structure to make the same rotor part dress can be reverse, the rotor part dress seals fully; Do not contact with medium, thus corrosion-resistant.
