Background technique
Domestic water is supplied with by water pressure tank on the large and medium-sized boats and ships, and the water pump that the conventional pressure water tank is equipped with mainly contains two types, and what application quantity was maximum is horizontal centrifugal vortex pump, and another kind is the direct connection vertical centrifugal pump.These two kinds of water pumps are less relatively because of volume, are particularly suitable for the limited cabin working environment in space.But still there are some structural imperfection in these two kinds of pumps in use, are prone to some faults take place, and influence water pressure tank and normally move.Since the cabin space little with the mobile characteristics of boats and ships, the supporting water pump inconvenient maintenance that breaks down in the navigation, promptness is poor.Horizontal centrifugal vortex pump most common failure is that impeller damages, and the reason of its damage is that the impeller of existing technology is a closed type structure, and blade is thinner.In case sneak into granule foreign in the domestic water of carrying, welding slag, the welding agent skin left over when particularly cabin is built are not cleaned out, and these granule foreigns are with the high speed flow blade of breaking.Direct connection vertical centrifugal pump most common failure is that pump seal lost efficacy, and causes motor to damage.In view of above-mentioned actual conditions, be that the supporting water pump of water pressure tank is to the reliability requirement particular importance on blue-water shipping and naval vessels.
The model utility content
The utility model is primarily aimed at the horizontal centrifugal vortex pump of existing technology and the deficiency that the supporting water pressure tank of direct connection vertical centrifugal pump is prone to break down, and proposes that a kind of hydraulic performance is good, efficient is high, the centrifugal vortex unipump of the horizontal self-priming of good reliability.
The utility model is realized technical goal through following technical proposals.
The centrifugal vortex unipump of horizontal self-priming, it comprises motor, pump shaft, carriage, pump case, the dextrorotation whirlpool pump housing, the left-handed whirlpool pump housing, pump cover, impeller, swirl vanes and black box.Said pump case is a horizontal type structure, and the top is provided with water outlet, and the right side constitutes agent structure through carriage and horizontally-arranged motor direct connection.The overhanging axle head direct connecting pump shaft of motor, pump shaft cooperates the formation shaft seal structure with the black box that install in pump case right-hand member hole.Its improvements are: be in pump shaft the positioning string dress dextrorotation whirlpool pump housing, swirl vanes, the left-handed whirlpool pump housing and impeller successively in the pump case inner chamber; The dextrorotation whirlpool pump housing that axially cooperates, swirl vanes and the left-handed whirlpool pump housing constitute the peripheral pump structure, and peripheral pump is arranged in the pump case inner chamber and directly links up water outlet.Said pump cover is two-way quarter bend pipe fitting; Lower end nozzle flange end face and the pump case open-mouth end formation centrifugal pump structure that is tightly connected; Coaxial and centrifugal pump delivery outlet and vortex pump intake that lean on are mutually linked up, and the pump cover upper end mouth of pipe is a suction port, its endoporus setting-in filter screen.Said swirl vanes is an open architecture, is uniformly distributed with radial blade on the circumference, circumference likeness in form shuttlecock front projection shape between the adjacent radial blade.
Black box adopts mechanical seal in the said structure, and the filter opening of filter screen is 30 orders～60 orders.
The utility model compared with prior art has following good effect:
1, coaxial bilobed wheel is simple in structure, compact, and is easy for installation;
2, easy manufacturing of the swirl vanes of open architecture and blade are thick, and the particle-resistant impact capacity is strong, long service life;
3, end thrust is little, helps the mechanical seal operation, good sealing effect;
4, peripheral pump structure entry port is a malleation, and net positive suction head is little, and pump efficiency is high.

Embodiment
According to accompanying drawing the utility model is described further below.
The centrifugal vortex unipump of horizontal self-priming shown in Figure 1, it comprises motor 1, pump shaft 2, carriage 3, pump case 4, the dextrorotation whirlpool pump housing 5, the left-handed whirlpool pump housing 6, pump cover 7, impeller 8, swirl vanes 9 and black box 10.Said pump case 4 is a horizontal type structure, and the top is provided with water outlet, and the right side constitutes agent structure through carriage 3 and horizontally-arranged motor 1 direct connection.Motor 1 overhanging axle head direct connecting pump shaft 2, pump shaft 2 cooperates the formation shaft seal structure with the black box 10 that install in pump case 4 right-hand member holes, and black box 10 is mechanical seal in the present embodiment.Be in pump shaft 2 the positioning string dress dextrorotation whirlpool pump housing 5, swirl vanes 9, the left-handed whirlpool pump housing 6 and impeller 8 successively in pump case 4 inner chambers; The dextrorotation whirlpool pump housing 5 that axially cooperates, swirl vanes 9 and the left-handed whirlpool pump housing 6 constitute the peripheral pump structure, and peripheral pump is arranged in pump case 4 inner chambers and directly links up water outlet.Said pump cover 7 is two-way quarter bend pipe fitting, lower end nozzle flange end face and the pump case 4 open-mouth ends formation centrifugal pump structure that is tightly connected, and coaxial and centrifugal pump and vortex pump intake that lean on are mutually linked up.The pump cover 7 upper end mouths of pipe are suction port, and its endoporus setting-in filter screen 7.1 as shown in Figure 5 is 30 order filter screens 7.1 in the present embodiment.Said swirl vanes 9 is an open architecture, is uniformly distributed with radial blade on the circumference, circumference likeness in form shuttlecock front projection shape between the adjacent radial blade.
When present embodiment used for the first time, at first from pump case 4 top water outlet water fillings, repeated use did not need water filling in the short time afterwards.Starting electrical machinery 1 drives peripheral pump and the coaxial rotation of centrifugal pump synchronously, and the water that centrifugal pump is introduced from suction port directly supplies water to the peripheral pump import, realizes that the peripheral pump import is a malleation, reduces net positive suction head greatly, and peripheral pump is exported from the water outlet high efficiency.The utility model adopts coaxial bilobed wheel structure, and it is simple, compact, easy for installation to remove structure, also significantly reduces axial force, helps the running of mechanical seal, improves sealing effect, avoids leaking and causes motor 1 to damage.Another improvement of the utility model is a swirl vanes 9 like Fig. 3, open architecture shown in Figure 4; Be uniformly distributed with radial blade on the circumference except that being prone to shape; Also has particle-resistant impact capacity preferably; This improvement improves the working life of swirl vanes 9 greatly, has strengthened the reliability that the centrifugal vortex unipump of horizontal self-priming uses, and satisfies the supporting water pressure tank service condition of ocean going vessel and naval vessels fully.
