Abstract
The utility model provides a guide vane type diving helico-centrifugal pump. The guide vane type diving helico-centrifugal pump consists of a suction section (1), an impeller (2), a guide vane (3), a shaft (4), a motor (5), a bearing (6), an oil cavity (7) and a mechanical seal (8). The guide vane type diving helico-centrifugal pump is characterized in that a water-pressurized chamber is formed by adopting the space guide vane (3) instead of a spiral volute, and effectively shortens the radial dimension of a pump. The guide vane can generally be manufactured alone, can also be processed by machining, and brings great convenience for processing and manufacturing. In addition, the space guide vane is installed in a lateral wall way, the motor and the oil chamber both can extend into a guide vane inner cavity, and therefore the radial dimension of the diving helico-centrifugal pump is effectively shortened, materials are saved, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of helico-centrifugal pump, particularly a kind of diving helico-centrifugal pump that adopts spatial guide blade.
Background technique
At present; Known helico-centrifugal pump mainly is made up of spiral receded disk impeller and volute, and the impeller inlet of its reaping hook shape can be screwed into the solid matter that is deposited in pump inlet on one's own initiative, as screw pump; Produce the screw propulsion effect, the impeller of volute part produces centrifugal action as centrifugal pump.The blade wheel structure of this kind uniqueness makes helico-centrifugal pump work the time both not have current and impacts, again can positive feed, and have the fabulous performance of passing through, thereby avoided the winding and the obstruction of foreign material, be widely used in the middle of the sewage treatment.Yet, because it adopts the spirality volute, increased the radial dimension of pump from face, it can not be applied in the environment that radially size limits to some extent; And its spiral flow channel can not machining, size shape, shows that degree of finish directly guarantees by casting, makes and the difficulty of processing thereby increased.
The model utility content
For addressing the above problem, the utility model adopts spatial guide blade to replace the spirality volute, has dwindled the radial dimension of pump greatly, and this kind stator generally can make separately, and can carry out machining, brings great convenience for processing and manufacturing.In addition, the form that its spatial guide blade also adopts sidewall to install, motor and grease chamber can stretch into the stator inner chamber, have effectively shortened the axial dimension of diving helico-centrifugal pump, have saved material, have reduced cost of production.
Realize that above-mentioned purpose adopted technological scheme be:
After impeller, adopt spatial guide blade to replace the spirality volute, vane inlet adopts the orthodrome transition, and it is axially effluented.And the mounting type of stator improved, no longer the grease chamber is directly installed on the stator end, but the stator inner chamber is goed deep in grease chamber and motor, the grease chamber is connected through screw with the stator internal chamber wall and fixes.The outer chamber wall of stator links to each other with the outer wall of suction casing through screw, thereby has realized the installation of stator.The spatial guide blade of this kind form makes the radial and axial length of pump shorten dramatically, and makes pump structure compact more, safeguards to installation and operation and has brought convenience, and particularly for large-scale vertical diving helico-centrifugal pump, effect is more obvious.
Above-described a kind of stator formula diving helico-centrifugal pump, mainly by suction casing (1), impeller (2), stator (3), axle (4), motor (5), bearing (6), grease chamber (7) and mechanical seal (8) are formed; It is characterized in that: pumping chamber takes spatial guide blade (3) to replace the structural type of spirality volute.
Described a kind of stator formula diving helico-centrifugal pump is characterized in that: the form that spatial guide blade (3) takes sidewall to install.
The utility model advantage is: effectively shortened the radial and axial size of whole pump, reduced the production and the operation expense of pump.
The beneficial effect of the utility model is: evaded big this shortcoming of helico-centrifugal pump radial dimension, realized the energy-saving material-saving of whole pump.
The utility model is on probation through the user, reflects respond wellly, and can be applied to has in the running environment of requirement size radially.

Embodiment
Fig. 1 is the structural type of diving helico-centrifugal pump in the present embodiment, mainly by suction casing (1), and impeller (2), stator (3), axle (4), motor (5), bearing (6), grease chamber (7) and mechanical seal (8) are formed.Take the structural type of spatial guide blade (3) replacement spirality volute, effectively dwindled the radial dimension of pump.
Fig. 2 is the axial plane figure of diving helico-centrifugal pump stator in the present embodiment; It is mainly by blade (10); Stator inwall (13) and stator outer wall (14) are formed in this example, take grease chamber (7) to be connected fixing mode with stator (3) inwall (13) through interior hexagonal round head bolt, and motor (5) directly is fixed on the top of grease chamber (7) through hexagon head bolt; And the outer wall (14) of stator (3) is fastened on the suction casing (1) through screw, thereby has realized installing and fixing of grease chamber (7), motor (5) and stator (3).This kind mounting type makes grease chamber (7) and motor (5) stretch into stator (3) inner chamber, thereby the axial dimension of pump is shortened dramatically.
Claims (2)
1. stator formula diving helico-centrifugal pump, mainly by suction casing (1), impeller (2), stator (3), axle (4), motor (5), bearing (6), grease chamber (7) and mechanical seal (8) composition; It is characterized in that: pumping chamber takes spatial guide blade (3) to replace the structural type of spirality volute.
2. a kind of stator formula diving helico-centrifugal pump according to claim 1 is characterized in that: the form that spatial guide blade (3) takes sidewall to install.
