Abstract
The utility model is composed of a pump body, a pump cover, a rotor, etc. The utility model is characterized in that the utility model is provided with a shell body; the pump cover is closed half, and the shell body and the pump cover are assembled into a sealing body; a bearing sealing body and the outer circumference of the sealing body are fixedly connected by screw bolts; an impeller wheel and a shaft of the rotor are fixedly connected respectively by a stable fixing and a stable locking sheaths. The pump provided with a cover of the structure has the advantages of good technology performance, easy casting and fabrication, simple component structure, etc.
Description
The utility model relates to a kind of pump.
Several middle-opening pumps of present domestic use, owing to be single group, double-sucking type and the different structure of stator casing shape so there is that manufacturability is poor, problem such as casting processing difficulty, part applicability are bad, are unfavorable for its production and are used.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of new structure middle-opening pump is provided, and compared with prior art, has good manufacturability, easily casting processing, advantage such as component structural is simple, applicability is good, and fabulous popularizing value is arranged.
The utility model is achieved through the following technical solutions.
The utility model is to be made of the pump housing, pump cover and rotor etc., it is characterized in that being provided with the pump housing, pump cover narrows and is assembled into a seal, and bearing support also is made as the sealing assembling and directly is contained on the seal, promptly by seal outer garden supporting.Between honey envelope body and bearing support, be provided with a link press span of being convenient to adjust Gland.On rotor shaft, also be arranged with and prevent lock sleeve, a loosening right-handed thread and the flat key of impeller.
Fig. 1, structural profile schematic representation of the present utility model.
Fig. 2, the utility model packing seal structure generalized section.
The structural profile schematic representation of Fig. 3, rotor part of the present utility model.
In conjunction with Fig. 1,2,3, by the following examples the technical program is further described.
Embodiment:
Referring to Fig. 1,2,3, the utility model is to be made of the pump housing 1, pump cover 2 and rotor 3 etc., it is characterized in that being provided with the pump housing 1, pump cover 2 narrows and be assembled into a seal, and adopt the screw rod nut to be connected between the pump housing 1 and the pump cover 2, bearing support 4 also is made as the sealing assembling, and be fixed by bolts on the seal, by seal outer garden supporting.Between seal and bearing support 4, be provided with a link press span 5, connect with bolt to each other.9,10 be respectively mechanical seal body and seal ring.Also be arranged with a right-handed thread and a flat key 8 on 36 of rotors, fixing and lock sleeves 7 are connected by flat key 8 respectively between impeller 11 and the axle 6.
Assembling of the present utility model and operation running, all basic identical with the pump of general type, so in this just no longer narration.
