Abstract
The utility model relates to the field of centrifugal pump design, particularly to a connecting structure of a high-hardness centrifugal pump and a pipeline, and includes an intake end cap and an intake flange of the centrifugal pump, and a plurality of mounting holes are formed in the intake flange. The connecting structure is characterized by also including an annular nut ring, and a plurality of mounting threaded holes are uniformly distributed in the nut ring; an annular groove is arranged in the intake end cap, an inverse T-shaped groove is arranged in the annular groove, the nut ring is embedded in the inverse T-shaped groove, and a connecting bolt end is arranged in the inverse T-shaped groove and sequentially penetrates the mounting threaded holes of the nut ring and the mounting holes of the intake flange so as to be fixed by a nut. The connecting structure overcomes the inconveniences brought by conventional boring and tapping, as long as the machining die of the intake end cap is slightly improved, the intake end cap can be completely matched with the intake flange. At the same time, the feasibility of utilizing the high-chromium iron and other high-hardness pumps is improved, and a guiding significance is achieved for the design as well as the research and development of the high-hardness centrifugal pump.
Description
Technical field
The utility model relates to the centrifugal pump design field, specifically relates to the linkage structure of a kind of high hardness material centrifugal pump and pipeline.
Background technique
In the existing technology, for being connected between the suction end cap of embedded flange and pump, mainly be through bolted, this just need suck drilling and tapping on the end cap.
Be higher than 600 high chromium cast iron material for Brinell hardness, boring is inconvenience very, needs the labor resource, if tapping processing can't realize almost that then this brings great inconvenience with regard to the processing of giving high hardness material centrifugal pump.
The model utility content
To the technical problem that exists in the existing technology, the purpose of the utility model is to provide the linkage structure that a kind of mounting structure is novel, connect reliable high hardness material centrifugal pump and pipeline.
The technological scheme that the utility model adopts is following:
The linkage structure of high hardness material centrifugal pump and pipeline, comprise centrifugal pump the suction end cap, suck flange, said suction flange is provided with several mounting holes, it is characterized in that, also comprises the collar nut circle, said nut circle is evenly equipped with several tapped hole is installed; Said suction end cap is provided with circular groove; Be provided with inverse-T-shaped groove in the said circular groove, said nut circle is embedded in the inverse-T-shaped groove, and the connecting bolt head end places inverse-T-shaped groove; Pass the installation tapped hole of nut circle, the mounting hole of suction flange successively, pass through fixed by nut again.
Further, be evenly equipped with several square grooves in the said circular groove, square groove and inverse-T-shaped groove adjacent distributions one by one in circular groove.
Further, said nut circle also is provided with a plurality of fastening screw pits, and said fastening screw pit is symmetrically distributed on the nut circle.
Further, said nut circle is locked through lock bolt with the suction end cap, and said lock bolt passes the fastening screw pit of nut circle and gos deep into the bottom of square groove.
The linkage structure of the utility model high hardness material centrifugal pump and pipeline has solved some row inconvenience that the conventional borehole tapping is caused, and only needs on suction end cap processed mould, to do a spot of change, can reach and the perfect cooperation that sucks flange.Simultaneously, the utility model has increased the feasibility of rich chromium cast iron and the utilization of other high hardness material pump, and research and development have the meaning of directiveness for high hardness material characteristic of centrifugal pump design.

Fig. 7 is the sectional view that sucks end cap and another angle of mounting structure that sucks flange.
Embodiment
The linkage structure of high hardness material centrifugal pump and pipeline as a kind of preferred embodiment, comprises suction end cap 2, suction flange 3 and the collar nut circle 1 of centrifugal pump, sucks flange and is provided with several mounting holes.
See also Fig. 1, nut circle 1 is evenly equipped with 12 tapped hole 5 is installed, and 4 symmetrical distribution fastening screw pits 4.
See also Fig. 2 and Fig. 3, suck end cap 2 and be provided with circular groove, be evenly equipped with 12 inverse-T-shaped grooves 6 and 12 square grooves 7 in the circular groove, square groove 7 and inverse-T-shaped groove 6 adjacent distributions one by one in circular groove.
12 connecting bolts 8 are passed the installation tapped hole 5 of nut circle 1, nut circle 1 is embedded in the inverse-T-shaped groove 6 again, see also Fig. 4, at this moment, the head end of connecting bolt 8 places square groove 7.
See also Fig. 7,4 lock bolts 9 are passed the fastening screw pit 4 of nut circle 1 and go deep into the bottom of square groove 7, thereby nut circle 1 and the relative position that sucks end cap 2 are fixed, it can't be rotated.
See also Fig. 6, will suck flange 3 and insert, make 12 connecting bolts 8 all pass the mounting hole that sucks flange 3,, be fixedly connected with suction flange 3 thereby will suck end cap 2 again through fixed by nut.
Above content only is to be given an example and explanation to what the utility model structure did; Under the technician in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of model utility or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
