Description
Technical field
The present invention relates to a kind of water pump structure, specifically, the present invention relates to a kind of jet-type self-priming centrifugal water pump.
Background technique
Centrifugal water pump belongs to main flow pump product, and is extensively supporting in conventional water-carriage system.From structure centrifugal pump suction capacity itself very a little less than, usually at the effect of additional self-priming apparatus realization self-priming down.The existing supporting self-priming apparatus of centrifugal pump has multiple structural type; Wherein structure the most simply is a built-in return port between pump housing water outlet and water sucking mouth; Centrifugal water pump starts the MEDIA FLOW of back impeller output and is shunted a part to the water sucking mouth through return port; Part MEDIA FLOW so circulation is facilitated the pump water sucking mouth to form negative pressure and is realized self-priming, and this structure exchanges the pump self-priming for through sacrificing pump efficiency.The structure of positive displacement retaining self-priming apparatus is equally also very simple, but volume is bigger, and it is supporting to be not suitable for boats and ships.Vacuum type self-priming apparatus compact structure realizes that self-priming time is short, and suction capacity is strong, but needs to be equipped with the kind equipment of corresponding air compressor or vacuum pump, increases match power thus, increases supporting cost.
Summary of the invention
The present invention is primarily aimed at the existing technology deficiency, proposes a kind of simple and reasonable for structurely, and suction capacity is strong, the jet-type self-priming centrifugal pump that efficient is high.
The present invention realizes technical goal through following technical proposals.
The jet-type self-priming centrifugal pump, it is a kind of horizontally-arranged structure pump, comprises the pump housing, nozzle, Diffuser, impeller, interior pump cover, stator, outer pump cover, pump shaft, carriage and motor.Said motor output shaft end face direct connection carriage, pump shaft is connected with motor coaxle, and the impeller location and installation is in the pump shaft end, and the pump cover cooperation constituted the centrifugal pump pump chamber structure in the impeller both sides were reached by outer pump cover and stator respectively.The said pump housing is the prone position open hood type container, and upper semisection is provided with the water sucking mouth towards the exterior edge face, and pump housing end face is provided with water outlet; Pump housing inner chamber is separated into two Room by the interior dividing plate of establishing; What link up the water sucking mouth is water sucting cavity, and what link up water outlet is water chamber, and dividing plate is provided with the aperture that Diffuser is installed.Its improvements are: the said pump housing is connected with outer pump cover end face seal with a uncovered end; Make the centrifugal pump pump chamber place pump housing inner chamber; Be uniformly distributed with axial hole on the interior pump cover end face and link up the water chamber of the pump housing; The Diffuser that between interior pump cover and dividing plate, is tightly connected, the coaxial installation nozzle in Diffuser end that is positioned at water sucking mouth one end constitutes jet pump structure, and the outlet port of Diffuser is in the inlet of impeller.
In the said structure, nozzle and Diffuser abutting end are provided with the threaded adjusting structure.
The present invention compared with prior art has following good effect:
1, jet pump and centrifugal pump organic assembling are simple in structure, are prone to make;
2, the water that the high pressure liquid stream of returning through nozzle helps to drive in the water sucting cavity gets into Diffuser, realizes that self-priming time is short, and suction capacity is strong;
3, the outlet port of jet pump is in the inlet of impeller, and jet pump helps the centrifugal pump self-priming, reduces centrifugal pump shaft power, reduces support expense.
Description of drawings
Fig. 1 is a structural profile schematic representation of the present invention.
Embodiment
According to accompanying drawing the present invention is described further below.
Jet-type self-priming centrifugal pump shown in Figure 1, it is a kind of horizontally-arranged structure pump, comprises the pump housing 1, nozzle 2, Diffuser 3, impeller 4, interior pump cover 5, stator 6, outer pump cover 7, pump shaft 8, carriage 9 and motor 10.Supporting motor 10 output shaft end face direct connection carriages 9, pump shaft 8 and 10 coaxial connections of motor, impeller 4 location and installation are in pump shaft 8 ends, and impeller 4 both sides constitute the centrifugal pump pump chamber structure by outer pump cover 7 and stator 6 and 5 cooperations of interior pump cover respectively.The said pump housing 1 is the prone position open hood type container; Upper semisection is provided with water sucking mouth 1.1 towards the exterior edge face; The pump housing 1 end face is provided with water outlet 1.2, and the pump housing 1 inner chamber is separated into two Room by the interior dividing plate 1.3 of establishing, and what link up water sucking mouth 1.1 is water sucting cavity; What link up water outlet 1.2 is water chamber, and dividing plate 1.3 is provided with the aperture that Diffuser 3 is installed.The said pump housing 1 installs on the impeller and with outer pump cover 7 end face seals with a uncovered end cover and is connected, and makes the centrifugal pump pump chamber place the pump housing 1 inner chamber.Be uniformly distributed with axial hole 5.1 on interior pump cover 5 end faces and link up the pump housing 1 water chamber; Diffuser 3 is tightly connected between interior pump cover 5 and dividing plate 1.3; The coaxial installation nozzle 2 in Diffuser end that is positioned at water sucking mouth one end constitutes jet pump structure, and the outlet port of Diffuser 3 is in the inlet of impeller 4.Nozzle 2 is provided with the threaded adjusting structure with Diffuser 3 abutting ends, through the axial position of adjustment nozzle 2, to reach the self-priming optimum condition.
The present invention is fills with water in starting the forward direction pump housing 1 water chamber, starts back impeller 4 high speed rotating, makes the water supercharging of water chamber, and wherein a part is carried the water of pressing through nozzle 2 ejection at a high speed, and the pressure of water can be changed into kinetic energy.High-velocity flow forms certain negative pressure through making water sucting cavity, and air under siphonage in the water sucting cavity and water are brought in the lump in the Diffuser 3 by high-velocity flow and mixed, and gas-liquid mixed flows to when reaching Diffuser 3 outlet sections; Because of making the kinetic energy of gas-liquid mixed stream, the internal taper hole diffusion changes into the pressure ability; This moment, the flow velocity of gas-liquid mixed stream reduced, and pressure raises, and air is further compressed the back and in the pump housing 1, realizes gas-liquid separation; Air is discharged through the water outlet 1.2 of the pump housing 1; Remaining water is got back to nozzle 2 under pressure and is circulated once more, again the surplus air in the water sucting cavity is sucked and mixes, and the number of steps that repeats above-mentioned deaeration minute can realize self-priming.
Organic assembling jet pump of the present invention and centrifugal pump reach performance complement.The outlet port of jet pump is in the inlet of impeller, and jet pump helps the centrifugal pump self-priming, and the self-priming process is short, suction capacity is strong, also reduces centrifugal pump shaft power, realizes energy-saving and cost-reducing purpose.In addition, the present invention is integrated, and does not need to be equipped with in addition self-priming apparatus, saves support expense.
