Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model It is clear, describe in detail.Described embodiment is only a part of the embodiment of the utility model.
The technical solution that the utility model solves above-mentioned technical problem is:
Referring to Fig. 3 and Fig. 4, the through-hole piece 6 that absorbs water is made of oblique through-hole 7, and oblique through-hole 7 has corresponding Parallel to the flow direction Oblique, oblique through-hole 7 can be various shape structure composition.Fig. 5 is only on the basis of absorbing water through-hole piece 6 and oblique through-hole 7 More a hole piece runner bridge 9,9 width of hole piece runner bridge are approximately equal to impeller water outlet, and there is oblique through-hole 7 on piece runner bridge 9 both sides in hole Hole piece runner bridge 9, which encloses, is attached to the work of impeller water outlet knockout press, and liquid is discharged on hole piece runner bridge 9 for a part of liquid Water outlet 8, for another same suction pressure of part on the through-hole outflow road junction 4 of oblique through-hole 7, hole piece runner bridge 9 can allow the stream of liquid It is dynamic more to there is inertia and impact force to reach reinforcing effect.Illustrate that water suction through-hole piece 6 and oblique through-hole 7 can be there are many morphosis groups At change slightly should be in the scope of this patent.Its through-hole piece 6 that absorbs water can be linked to be body with pump case 1 and cast, and can also will inhale Water through-hole piece 6 coincide by modes such as screws to be fixed in pump case 1.The layout and size range of the water suction through-hole piece 6 of this patent Interior requirement is extremely stringent, while the size at through-hole outflow road junction 4 and the size of oblique through-hole 7 will be done by a certain percentage with layout At so that it is compact to exert pressure, strength is powerful, reaches the optimum lift effect of certain flow.
This patent further includes water seal, and impeller 2 (can be applied) containing open type, semi-open type, enclosed impeller, sealing device Deng.In centrifugal pump, referring to Fig. 1,1 inner flow passage of pump case is provided with water suction through-hole piece 6, and water suction through-hole piece 6 has corresponding oblique logical There is the through-hole being arranged to outflow road junction 4 and through-hole inner flow passage slot 5 in hole 7, there is a corresponding water outlet 8, the impeller intake 3 of docking, The initial end of water suction through-hole piece 6 is close to or is linked to be body in pump case 1, from drawing it can be seen that water suction through-hole piece 6 is about in water outlet Nearby it is tightly attached to pump case, this is conducive to suction pressure work of entire pump case process, and the rearmost end for the through-hole piece 6 that absorbs water is towards water outlet 8.
Referring to fig. 2, when being used for self priming pump, as Fig. 3, Fig. 4, Fig. 5 case, impeller 2 includes water suction through-hole piece 6 Open type, semi-open type, closed dress are used, and water suction through-hole piece 6 is rack-mount, outside impeller intake and water suction through-hole piece 6 There is (only one water outlet around some impeller housings, and there are one small water outlets for housing inner edge of self-suction pump impeller housing 10 Equal similar structures, similarly this patent can be applied and protection), the through-hole outflow road junction 4 of formation and through-hole inner flow passage slot 5, with water outlet Mouth 8.The initial end of water suction through-hole piece 6 is close to or is linked to be body in self-suction pump impeller housing 10, the rearmost end court for the through-hole piece 6 that absorbs water To water outlet 8.Water seal 11 is seen in Fig. 2, the impeller mouth of reasoning is just no longer drawn and indicated;Sealing outside self-suction pump impeller housing Circle, resistance water sucking mouth back flow plate etc. attachment device with commonly use as self priming pump and (no longer draw and explanation).
When this patent works, by liquid spinning on water suction through-hole piece 6 and oblique through-hole 7, through-hole outflows the knockout press of impeller Road junction 4 generates and suppresses runner, and liquid is attracting to be pressed in oblique through-hole 7 and water suction through-hole piece 6 (or the hole piece runner bridge in Fig. 5 case 9) on, acceleration water outlet is discharged energetically, this process runner formed speed-up ratio outflow, although when high load capacity the rebound of liquid and return Stream pressure can also be lacked as far as possible, then, the impact force of water is discharged from water outlet 8 energetically.It can be in the knot of same power and impeller Flow lift is improved on structure, because being also that can improve for suction when the high knockout press of lift is big.Again because being phase in the pump case of this patent Mutual suction pressure, conducive to rotating again for impeller, the loss of power consumption is reduced, wear and tear in machines is reduced and the excessive oil consumption of power is lost.
The above embodiment is interpreted as being merely to illustrate the utility model rather than limits the guarantor of the utility model Protect range.After the content for the record for having read the utility model, technical staff can make various changes to the utility model Or modification, these equivalence changes and modification equally fall into the utility model claims limited range.
