As shown in Fig. 1 ~ 3, wherein, Fig. 1 is the internal cross section structural representation of this utility model self-adjusting type energy-saving centrifugal pump；Fig. 2 is the movable hyoplastron schematic diagram being suitable for vertical vane in this utility model；Fig. 3 is to be suitable for non-perpendicular blade and the movable hyoplastron schematic diagram of runner bending in this utility model.
A kind of self-adjusting type energy-saving centrifugal pump, described centrifugal pump includes pump case 1, pump intake 2, pump discharge 3, and is positioned at described pump case 1 and connects the pump chamber 4 of pump intake 2 and pump discharge 3, is provided with the removable impeller of postnotum 5 in described pump chamber 4；Being additionally provided with regulation chamber 6 in described pump case 1, be provided with moveable end plate 7 in described regulation chamber 6, regulation chamber is divided into two relatively independent Guan Bi chamber and open cavities by described end plate 7；Wherein, described pump discharge 3 connects the liquid feeding end of pressure feedback pipe 8, and described pressure feedback pipe 8 liquid outlet turns on the Guan Bi intracavity portion regulating chamber 6；The open cavity in described regulation chamber 6 is internal with pump chamber 4 docks conducting, and in described open cavity, it is provided with Crossed Circle Bellows expansion set 9 and front end-plate 10, described telescopic 9 two ends are connected on end plate 7 and front end-plate 10, described front end-plate 10 is fixed with rotary connector 11 away from side, telescopic 9 direction, it is hinged in the middle part of a movable hyoplastron 12 on described rotary connector 11, described hyoplastron 12 afterbody stretches in pump chamber 4, and described hyoplastron 11 head holds on spindle nose set 13, in described spindle nose set 13 is fixed on pump case 1 and be positioned at the joint of open cavity and pump chamber 4.
In this utility model embodiment, for ease of the pressure in Guan Bi intracavity portion in control and regulation chamber 6, described pressure feedback pipe 8 is provided with regulation valve 14 and piezometer 15.
In actual application of the present utility model, when fluid is entered the removable impeller of postnotum 5 by pump intake 2, pumping chamber is set in entering pump case pump chamber 4(pump chamber 4 after the removable impeller of postnotum 5 throws away) in, pump discharge 3 pressure increases, and the size of pump discharge 3 pressure is relevant to flow.nullWhen pipe-line system necessary flow reduces，Pump discharge 3 pressure increases，Regulation valve 14 in pressure regulation circuit is opened greatly automatically，Reflux fluid is imported pump chamber by pressure feedback pipe 8、Enter Crossed Circle Bellows expansion set 9，Owing to differential pressure action causes Crossed Circle Bellows expansion set 9 elongation，The movable hyoplastron 12 connected by rotary connector 11 runner between blade is thus driven to move，Simultaneously because spindle nose overlaps the 13 base plane edges position-limiting action to movable hyoplastron 12 contact surface (such as D point in figure)，Movable hyoplastron 12 rotates around rotary connector 11，So Crossed Circle Bellows expansion overlap 9 elongations less time，Movable hyoplastron 12 front end runner between blade can be made to have bigger displacement，Movable hyoplastron 12 is made to block reduction flow area，As shown in Figure 1，Movable hyoplastron by A for moving to B position，Thus realize self-regulation and reduce the output flow of pump，Because revolution speed、Impeller diameter is constant，Lift is basicly stable；Otherwise, then realizing self-regulation increases the output flow of pump.In a word, thus can realize pump self-adjusting energy-saving to run.
When unexpected termination of pumping, no matter which kind of Crossed Circle Bellows expansion set 9 is in and stretches contraction state, and movable hyoplastron 12 is under refluence fluid matasomatism, automatic turning is blocked reduction flow area, as it is shown in figure 1, movable hyoplastron is moved to C position by A position, can play and reduce the non-return effect that liquid flows backwards.
Movable hyoplastron 12 can carry out without hindrance functional action between multiple blade, therefore is applicable to the centrifugal pump of multiple blade.
In this utility model embodiment, more specifically, when movable hyoplastron 12 is at the prismatic blade that postnotum removable impeller 5 is vertical, rotary connector 11 is articulated elements, movable hyoplastron 12 be out of plumb blade or when being camber blades, rotary connector 11 is universal joint at the removable impeller of postnotum 5.
Or, movable hyoplastron 12 adapts with rotary connector 11 design, and when rotary connector 11 is articulated elements, movable hyoplastron 12 afterbody is plane；When rotary connector 11 is universal joint, movable hyoplastron 12 afterbody is cusped edge shape or circular arc.
This utility model pump discharge is variable, and lift is basicly stable, solve the flow reduction that variable frequency regulating speed control pump generally exists, the problem that lift reduces the most accordingly, it is thus possible to preferably meet energy-saving centrifugal pump to the stable performance requirement of lift, additionally carry the check function preventing reverse flow of fluids.This pump structure is simple, cheap, energy-saving effect notable, has good application prospect.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
