Abstract
The invention discloses a centrifugal pump comprising a pump body, a pump cover, a rotor subassembly and an impeller arranged in the pump body, wherein the pump cover detachably covers the pump body; the rotor subassembly penetrates through the inside of the pump body; two ends of the rotor subassembly are arranged outside the pump body; the impeller is fixedly arranged on the rotor subassembly; the pump body is also provided with an additional pipeline system; one end of the rotor subassembly is provided with a shaft coupling subassembly and a front bearing subassembly, and the other end of the rotor subassembly is provided with a bearing subassembly; the front bearing subassembly is located between the shaft coupling subassembly and the pump body; and a pump body sealing ring is arranged between the inner wall of the pump body and the impeller. The centrifugal pump is small in size, good in shakeproof effect and convenient to maintain and dismount, and the sealing rings are easily mounted and located.
Description
Technical field
The present invention relates to pump, it is specially a kind of impeller pump.
Background technology
Two-throw pump is extensively for carrying clear water or be similar to the medium of clear water. In prior art, two-throw pump adopts horizontal middle open type pump body structure, single-stage double-entry centrifugal formula impeller, and its suction port and relief outlet are positioned on same medullary ray, and level sucks, discharges medium, and motor can be arranged on left side or the right side of pump as required. But because runner adopts trapezoidal runner, volume is big, and bearing two ends support interval is long, and same rotor part is not reversible, and axle and medium contact are not corrosion-resistant, and therefore running maintenance is inconvenient.
Summary of the invention
Technical problem solved by the invention is to provide a kind of impeller pump, with the shortcoming solved in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
Impeller pump, comprise the pump housing, pump cover, rotor portions dress and the impeller being arranged in the pump housing, described pump cover covers removably on the described pump housing, described rotor portions fills through described pump body, the two ends of described rotor portions dress are outside the described pump housing, described impeller is fixed on described rotor portions and loads onto, the described pump housing is also provided with additional line system, one end of described rotor portions dress is provided with shaft coupling portion dress and front axle bearing portion dress, the other end of described rotor portions dress is provided with bearing portion dress, described front axle bearing portion dress is between described shaft coupling portion dress and the described pump housing, it is provided with casing ring between described pump housing inwall and described impeller.
Preferably, described front axle bearing portion dress is fixed on the described pump housing by threaded stud and headkerchief nut. Described bearing portion dress is fixed on the described pump housing by threaded stud and headkerchief nut.
In the present invention, trapezoidal runner changes rectangularl runner into, shortens bearing two ends support interval, adds the rigidity of rotor, and adopts and make the same rotor part can be reverse without helicitic texture, and axle seals completely, not with medium contact, thus corrosion-resistant.
Useful effect
Rotor portions of the present invention dress is fixed in the pump housing, and shockproof effect is good, and axle is corrosion-resistant, and pump cover can be dismantled so that repair demolition is convenient, wear ring easily installs location.
Accompanying drawing explanation
Fig. 1 is the structure iron of impeller pump.
Embodiment
In order to the present invention is realized technique means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
See Fig. 1, the structure iron of impeller pump, impeller pump, comprise the pump housing 7, pump cover 2, the impeller 6 that rotor portions fills 1 and is arranged in the pump housing, described pump cover 2 covers removably on the described pump housing 7, it is inner through the described pump housing 7 that described rotor portions fills 1, the two ends of described rotor portions dress are outside the described pump housing, described impeller 6 is fixed on described rotor portions and loads onto, the described pump housing is also provided with additional line system 4, one end that described rotor portions fills 1 be provided with shaft coupling portion fill 9 and front axle bearing portion fill 8, the other end that described rotor portions fills 1 is provided with bearing portion and fills 5, described front axle bearing portion fills 8 and fills between 9 and the described pump housing 7 in described shaft coupling portion, it is provided with casing ring 3 between the described pump housing 7 inwall and described impeller 6.
Specifically, described front axle bearing portion is filled 8 and is fixed on the described pump housing by threaded stud and headkerchief nut. Described bearing portion is filled 5 and is fixed on the described pump housing by threaded stud and headkerchief nut. In above-mentioned impeller pump, runner is rectangularl runner, and axle can oppositely be installed. And described axle is hermetically sealed axle, not with medium contact.
More than show and describe the ultimate principle of the present invention and the advantage of main feature and the present invention; the technician of the industry should understand; the present invention is not restricted to the described embodiments; the principle that the present invention is just described described in above-described embodiment and specification sheets; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
