In the utility model, the water inlet rubber valve is arranged at the location of the intake line, thus effectively preventing the refluence problem of the water in the pump body and ensuring the working performance of the self-priming pump.
Description
Technical field
The utility model relates to a kind of pump, relates in particular to a kind of direct-connection type vertical self-priming centrifugal pump with suction capacity.
Background technique
Before startup, must in the pump housing, pour under the situation of enough water (or suction line is full of by water) in order to solve Ordinary Centrifugal Pumps at every turn, can make the pump proper functioning, very inconvenient.And self-priming centrifugal pump when needing only initial start-up, pours into enough water in the pump housing, and the effect by pump itself can run well within a short period of time, starts later on, guarantees that because of leaving water in the pump pump can start once more.Common self-priming centrifugal pump is divided into three kinds at present, be respectively the gas-liquid mixed formula, water ring is wheeled, jet-type, the working procedure of gas-liquid mixed formula self-priming pump: because the special construction of the self-priming pump pump housing, after the water pump stall, there is a certain amount of water in the pump housing, pump starts the back once more because the impeller turning effort, the empty G﹠W of suction line fully mixes, and be discharged to air-water separation chamber, and the gas on air-water separation chamber top overflows, and the water of bottom returns impeller, again the surplus air with suction line mixes, up to the gas in pump and the suction pipe is all discharged, finish self-priming, and normally draw water.The wheeled self-priming pump of water ring is that water ring wheel and water pump vane are combined in the housing, by the water ring wheel gas is discharged, and realizes self-priming.After the pump proper functioning, can block the passage of water ring wheel and water pump vane by valve, and bleed off the liquid in the water ring wheel.The jet-type self-priming pump is combined by centrifugal pump and Jet injector (or sparger), relies on injection apparatus, causes vacuum to realize suction at the nozzle place.Wherein the wheeled and jet-type of water ring exists self-priming weak effect, defective such as bulky, and the combination property of gas-liquid mixed formula self-priming centrifugal pump is better, so that uses is comparatively extensive, but there be the problem of the interior water of the pump housing, thereby influence the service behaviour of pump by the intake line backflow.
The model utility content
The utility model is at above-mentioned defective, and purpose is to provide a kind of straight connection type self-priming centrifugal pump that can prevent water reflux problem in the pump housing.
The technical solution of the utility model is: the utility model comprises the pump housing that has pump chamber and is positioned at the impeller that pump chamber is driven by pump shaft by motor, the pump housing is provided with intake line and the discharge conduit that is communicated with pump chamber, be provided with in the pump housing and the corresponding stator that is provided with of impeller, the intake line place is provided with into water one-way valve.
Maintain the radial clearance between the 2-3mm between stator and the impeller, stator top is provided with return port.
Be provided with seal ring between the impeller inlet place and the pump housing, the gap of sealing is between the 0.3-0.5mm.
The utility model is provided with the into unidirectional glue valve of water at the intake line place, effectively prevented the reflux problem of water in the pump housing, has guaranteed the service behaviour of self-priming pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is motor, the 2nd among the figure, liquid filling hole, the 3rd, and discharge conduit, the 4th, seal, the 5th, impeller, the 6th, stator, the 7th, the pump housing, the 8th, base, the 9th, pump shaft, the 10th advances the unidirectional glue valve of water, the 11st, intake line, the 12nd, return port, 13, the 14th, seal ring, 15 is a suction chamber.
Embodiment
The utility model comprises the pump housing 7 that has pump chamber and is positioned at the impeller 5 that pump chamber is driven by pump shaft 9 by motor 1, be provided with the intake line 11 and the discharge conduit 3 that are communicated with pump chamber in the pump housing 7, be provided with in the pump housing 7 and the impeller 5 corresponding stators 6 that are provided with, intake line 11 places are provided with into water glue valve 10.Maintain the radial clearance between the 2-3mm between stator 6 and the impeller 5, stator 6 inwalls are formed with towards the runner of impeller 5 outer circumferential sides, stator 6 tops are provided with return port 12, be provided with seal ring 13,14 between impeller 5 inlets and the pump housing 7, the gap of sealing is between the 0.3-0.5mm, and the pump housing 7 is installed on the base 8.
Working procedure of the present utility model is: when pump starts first, the water of capacity will be added by the liquid filling hole on the seal 42 in the pump housing 7, must flood impeller 5, starting electrical machinery 1, motor 1 rotation drives pump shaft 9, make impeller 5 rotations, with the water in suction chamber 14 and the impeller 6, be transported to stator 6 inlets through impeller 5 centrifugation effect, be drained into pump chamber through stator 6, after the water of suction chamber 15 is by impeller 5 emptyings, gas in suction chamber 15 and the inlet pipeline enters impeller 5, forms gas in stator 6 outlet ports, the liquid phase mixture, different and carry out gas by the proportion of water and gas, liquid separates, gas is discharged from through outlet pipe, and the return port 12 of water on seal 4 got back to impeller 5.Along with carrying out repeatedly of this process, the air in the inlet pipeline is constantly by emptying, and water charges into suction line gradually, and this process is about about 2min, and pump begins normal operation.When pump quit work, the pump housing 7 internal memories left the water that enough allows pump normally move once more, settled the unidirectional glue valve 10 of water inlet at the suction port place, and the water in the pump housing 7 are unlikely by intake line 11 backflows.When pump is activated once more, because the water of retention is arranged in the pump, need not to add water by liquid filling hole 2, just can make the pump proper functioning.
Working principle of the present utility model is: so self-priming centrifugal pump can be seen water off is because action of centrifugal force.Water pump is before work, the pump housing 7 and suction chamber be must jar full water capable to become vacuum state, when impeller 5 quick rotation, blade impels the very fast rotation of water, the water that is rotating flies to enter stator 6 from impeller 5 under action of centrifugal force, reason gas-liquid separation owing to proportion, gas is discharged by discharge conduit 3, and a part of water is got back to impeller 5 by return port 12, after the water in the pump is dished out, the core of impeller 5 forms vacuum area, the water at water source is opened the into unidirectional glue valve 10 of water under the effect of atmospheric pressure, gas enters in the pump housing 7, repeats above-mentioned circulation again, gradually the air in the pump is drained, realize continuous pumpage, when pump quits work, the barometric pressure balance that pump is inside and outside, the unidirectional glue valve of intaking cuts out, and has prevented the problem that water refluxes.
The utility model is in order to strengthen the service behaviour of pump, adopt stator 6 structures, after water comes out from impeller 5, have certain pressure energy and kinetic energy, behind stator 6, speed reduces, kinetic energy changes into pressure energy, formation has the water of certain pressure energy, and stator 6 also can be eliminated liquid from rotatablely moving that impeller comes out, and avoids the energy loss of bringing thus.
