Description
Technical field
The utility model relates to a kind of centrifugal pump suction inlet priming apparatus.
Background technique
General taken out by water in a pond toward another one local, all need to use pump, centrifugal pump is one wherein, first the general principle describing lower centrifugal pump, and centrifugal pump utilizes vane rotary and centrifugal force that water is produced carrys out work.But centrifugal pump before activation, must make to be full of water in pump case and suction sleeve, then starting electrical machinery, pump shaft impeller and water is made to do high speed rotary motion, water under the influence of centrifugal force, is thrown toward impeller outer edge, and the runner through volute pump case flows into the setting-out pipeline of water pump.Water pump vane center, because water is thrown out of rear formation vacuum under the influence of centrifugal force, the water in priming reservoir is just pressed in pump case under the effect of atmospheric pressure, and impeller is by gyrating, make water constantly flow under the effect of impeller and flow out, reach the object of conveying water.Find out from principle, centrifugal pump is when starting, manually now must be full of water by pump case and water pipe, normally water could be smoked, so generally all fill a safety check at suction inlet, but fill safety check and obviously can strengthen pipe resistance, and at suction inlet place once there be dirt, just easily cause blocking, if but not loaded check valve, when adding water manually to pump case and suction inlet pipeline, water will flow to pond from back of pipeline, so just require that the speed of adding water is greater than back-flow velocity, the water of the inside could be filled, open water pump again, operate like this and bother very much.My department has several ponds periphery to have many foreign material in addition, and it is distant that water pump can only be put, and such suction pipe just needs to lengthen, and manually adds water and just more requires great effort.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of centrifugal pump suction inlet priming apparatus, and this apparatus structure is simple, has simple to operate, more laborsaving.
In order to realize above-mentioned object, the utility model have employed following technological scheme:
A kind of centrifugal pump suction inlet priming apparatus, this device comprises motor, centrifugal pump, water pump suction inlet pipeline, water tank, intake pipe and inlet valve, pond suction inlet pipeline and pond; Centrifugal pump is connected to the bottom on the left of water tank by water pump suction inlet pipeline, and the right upper portion of water tank is provided with osculum, described intake pipe connection is arranged on osculum, inlet valve is arranged on intake pipe, also be connected on osculum by pond suction inlet pipeline, the other end of pond suction inlet pipeline is connected with pond simultaneously; Reach suction inlet pipeline place, pond for cistern water level with water level in water tank, the spatial volume filling water below cistern water level with mouth piece pipeline is designated as A, and the spatial volume to pond above cistern water level is designated as B, and part A volume is greater than part B volume.
The utility model, owing to have employed above-mentioned technological scheme, provides a kind of centrifugal pump suction inlet priming apparatus, and this apparatus structure is simple, has simple to operate, more laborsaving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
A kind of centrifugal pump suction inlet priming apparatus as shown in Figure 1, this device comprises motor 1, centrifugal pump 4, water pump suction inlet pipeline 5, water tank 6, intake pipe 8 and inlet valve 7, pond suction inlet pipeline 9 and pond 10, motor 1 connects the impeller of centrifugal pump, is provided with water outlet 3 above centrifugal pump; Centrifugal pump is connected to the bottom on the left of water tank 6 by water pump suction inlet pipeline 5, and the right upper portion of water tank 6 is provided with osculum, described intake pipe 8 connection is arranged on osculum, inlet valve 7 is arranged on intake pipe 8, also be connected on osculum by pond suction inlet pipeline 9, the other end of pond suction inlet pipeline 9 is connected with pond 10 simultaneously; Reach suction inlet pipeline 9 place, pond for water tank 6 water level with water level in water tank 6, the spatial volume filling water below water tank 6 water level with mouth piece pipeline is designated as A, and the spatial volume to pond 10 above water tank 6 water level is designated as B, and part A volume is greater than part B volume.
Specific operation are as follows, before centrifugal pump 4 is opened, first open valve 7 toward water filling inside water tank 6, water slowly can fill it up with water tank 6 and water pump suction inlet pipeline 5, until water level reaches pond suction inlet pipeline 9 in water tank 6, the water that now adds water again will be back in pond 10 from pond suction inlet pipeline 9, so now throttle down 7 stops adding water, but here we have a principle followed, we specially change the openning above water tank 6 little, become near that side of suction inlet pipeline 9, pond, exactly in order to reduce above water tank 6 water level to the volume of air in this section of pipeline in pond 10, B is designated as at this.By below water tank 6 water level and this part spatial volume filling water of mouth piece pipeline 5 be designated as A.Volume A must be allowed during design to be greater than volume B, like this when after open water pump motor 1, impeller 2 rotates, the water of such part A just can be quickly drawn out, send from water outlet 3, because A volume is greater than part B, so when the water in part A is drawn out of in process again, part B forms vacuum, and the water in pond 10 is just pressed in pipeline and water tank 6 under the effect of atmospheric pressure, because A volume is greater than B, when the water of part A exhausts, the water of part B has also been forced into water tank 6, and with regard to moment water abrim in such water tank 6, water just can be extracted out from pond 10 always.
