The technical solution of the utility model is: a kind of high efficient horizontal self-priming centrifugal pump, it is characterised in that: it is described from
Heart pump includes the internal layer pump housing 1, and the internal layer pump housing 1 is connected with pump cover 2, and pump cover 2 is then connected with bearing housing 3 by studs, in axis
Holding in case 3 has impeller shaft 5 by two 4 rotational supports of deep groove ball bearing, and is equipped with a bearing with each deep groove ball bearing 4
Gland 6, one end of the impeller shaft 5 are located at the outside of bearing housing 3, and the other end is then connected with impeller 7, and 7, the impeller
It being formed by cavity in the internal layer pump housing 1 and pump cover 2, one section in impeller shaft 5 positioned at 2 inner cavity of pump cover is above equipped with mechanical seal,
Breather plug 8 is additionally provided on bearing housing 3,
The arrival end of the internal layer pump housing 1 is connected with entrance pipe 9, and outer pump shell 10, outer layer are provided with outside entrance pipe 9
11 tilt distribution of top plate of pump case 10, the angle between horizontal plane is 3-8 °, while being additionally provided with and having on top plate 11
The exhaust outlet 12 of sealing-plug, and the exhaust outlet 12 is located at the higher one end of top plate 11, the level of 1 outlet end of the internal layer pump housing
Height is higher than the level height of the central axes of entrance pipe 9, at the same be also bolted to connection inside the internal layer pump housing 1 every
Tongue 13.
The utility model compared with the existing technology, has the advantages that
The high efficient horizontal self-priming centrifugal pump of this kind of structure type, simple in sturcture, ingenious in design, rationally distributed, it is directed to
The slow problem of water speed on traditional horizontal self-suction centrifugal pump, the top plate of outer layer pump case is obliquely installed, and is arranged in higher position and is arranged
Port can allow the exhaust of outer layer pump case more thorough in this way, while speed is accelerated, and then improve upper water speed；While it
The outlet height of the internal layer pump housing is higher than the center line of suction of the outer layer pump housing, can make water (and secondary upper water) speed in this way
Obviously speed；Cut water in its internal layer pump housing is assembly parts, thus may be implemented precisely to process, allow between cut water and impeller
Gap is easier to ensure that, to improve the whole work efficiency of pump；And since cut water is detachable, in cutting impeller
When cover board can be cut simultaneously, it is not necessary to impeller cover is worried and the problem of separation tongue gap is difficult to ensure, to reduce
The cost of machining；And the manufacture craft of this centrifugal pump is simple, and manufacturing cost is cheap, it can be said that it has
A variety of advantages, particularly suitable for promoting and applying in the art, market prospects are very wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the lateral view of the utility model embodiment.
Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.It is as shown in Figure 1 and Figure 2: a kind of high efficient horizontal
Self-priming centrifugal pump, it includes the internal layer pump housing 1, and the internal layer pump housing 1 is connected with pump cover 2, and pump cover 2 then passes through studs with bearing housing 3
It is connected, has impeller shaft 5 by two 4 rotational supports of deep groove ball bearing in bearing housing 3, and match with each deep groove ball bearing 4
There is a bearing gland 6, one end of the impeller shaft 5 is located at the outside of bearing housing 3, and the other end is then connected with impeller 7, and described
Impeller 7 be located at the internal layer pump housing 1 and pump cover 2 is formed by cavity, be equipped on one section of 2 inner cavity of pump cover in impeller shaft 5
Mechanical seal is additionally provided with breather plug 8 on bearing housing 3,
The arrival end of the internal layer pump housing 1 is connected with entrance pipe 9, and outer pump shell 10, outer layer are provided with outside entrance pipe 9
11 tilt distribution of top plate of pump case 10, the angle between horizontal plane is 3-8 °, while being additionally provided with and having on top plate 11
The exhaust outlet 12 of sealing-plug, and the exhaust outlet 12 is located at the higher one end of top plate 11, the level of 1 outlet end of the internal layer pump housing
Height is higher than the level height of the central axes of entrance pipe 9, at the same be also bolted to connection inside the internal layer pump housing 1 every
Tongue 13.
The course of work of the high efficient horizontal self-priming centrifugal pump of the utility model embodiment is as follows: due to its outer layer pump case 10
11 tilt distribution of top plate, while the exhaust outlet 12 being arranged on top plate 11 is located at its higher one end again, therefore is sucting water certainly
When, the gas in outer layer pump case 10 can be quick, smooth and be thoroughly discharged from exhaust outlet 12, prevent because be vented it is unsmooth due to lead
The excessively slow problem of water in cause；
Meanwhile the level height of the outlet end of the internal layer pump housing 1 is higher than the level height of the central axes of entrance pipe 9,
The reason of this design is as follows: when termination of pumping, the water body of two layers of pump body can back sucking from the entrance of outer layer pump case 10
In pond, and the liquid in outer layer pump case 10 needs to export by the internal layer pump housing 1 first, then passes through the spiral case of the internal layer pump housing 1
Back in sucking pond；Therefore when 1 outlet height of the internal layer pump housing is higher than the center line of 10 entrance pipe 9 of outer layer pump case,
Then the outlet of the internal layer pump housing 1 can effectively obstruct the liquid reflux in outer layer pump case 10, so that can save in outer layer pump case 10
More water, when restarting, then no longer need to fill pump, thoroughly prevented can not restarting the problem of；
Meanwhile the cut water 13 being arranged in the internal layer pump housing 1 is bolted in the inner cavity of the internal layer pump housing 1, that is,
It says that this cut water 13 is assembly parts, the accurate processing for cut water 13 thus may be implemented, cut water can be effectively ensured in this way
The accuracy in the gap between 13 and impeller 7, to improve the whole work efficiency of pump；Simultaneously because cut water 13 does not need directly
It connects processing on the cover board, therefore cover board can be cut simultaneously when cutting impeller 7 in the way of mach, from
And reduce the cost of machining.
