The service reliability of the horizontal self-priming centrifugal vortex sundstrand pump is improved and the complementary conditions for ocean vessel pressure tanks are satisfied.
Description
Technical field
The present invention relates to a kind of water pump peculiar to vessel, specifically, the present invention relates to a kind of Horizontal-type self-absorption centrifugal-peripheral combination pump of bilobed wheel structure.
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 traditional water pressure tank is equipped with mainly contains two types, and what application quantity was maximum is the horizontal centrifugal peripheral pump, and another kind is the direct connection vertical centrifugal pump.These two kinds of water pumps are particularly suitable for the cabin working environment of limited space because of the volume less.But still there are some structural imperfection in these two kinds of pumps in use, and some faults easily occur, and affect water pressure tank and normally move.Because the mobile characteristics of the little and boats and ships in cabin space, the supporting water pump inconvenient maintenance that breaks down in the navigation, promptness is poor.Horizontal centrifugal peripheral pump most common failure is that impeller damages, and the reason of its damage is that the impeller of prior art is 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 velocity liquid stream 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 at blue-water shipping and naval vessels.
Summary of the invention
The present invention proposes the Horizontal-type self-absorption centrifugal-peripheral combination pump that a kind of hydraulic performance is good, efficient is high, reliability is strong mainly for the deficiency that horizontal centrifugal peripheral pump and the supporting water pressure tank of direct connection vertical centrifugal pump of prior art easily breaks down.
The present invention is achieved through the following technical solutions technical goal.
Horizontal-type self-absorption centrifugal-peripheral combination pump, 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.Described pump case is horizontal type structure, and the top is provided with water outlet, and the right side consists of agent structure by 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 successively the positioning string dress dextrorotation whirlpool pump housing, swirl vanes, the left-handed whirlpool pump housing and impeller in the pump case inner chamber, the dextrorotation whirlpool pump housing that axially cooperates, swirl vanes and the left-handed whirlpool pump housing consist of the peripheral pump structure, and peripheral pump is arranged in the pump case inner chamber and directly links up water outlet.Described 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, centrifugal pump delivery outlet and vortex pump intake coaxial and that lean on are mutually linked up, and the pump cover upper end mouth of pipe is suction port, its endoporus setting-in filter screen.Described swirl vanes is open architecture, uniform 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 present invention compared with prior art has following good effect:
1, coaxial bilobed wheel is simple in structure, compact, and is easy for installation;
2, the 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, is conducive to the mechanical seal operation, good sealing effect;
4, peripheral pump structure entry port is malleation, and net positive suction head is little, and pump efficiency is high.

Embodiment
The invention will be further described with reference to the accompanying drawings for the below.
Horizontal-type self-absorption centrifugal-peripheral combination pump 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.Described pump case 4 is horizontal type structure, and the top is provided with water outlet, and the right side consists of agent structure by 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 successively the positioning string dress dextrorotation whirlpool pump housing 5, swirl vanes 9, the left-handed whirlpool pump housing 6 and impeller 8 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 consist of the peripheral pump structure, and peripheral pump is arranged in pump case 4 inner chambers and directly links up water outlet.Described 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 centrifugal pump and vortex pump intake coaxial and that lean on are mutually linked up.The pump cover 7 upper end mouths of pipe are suction port, and its endoporus is setting-in filter screen 7.1 as shown in Figure 5, are 30 order filter screens 7.1 in the present embodiment.Described swirl vanes 9 is open architecture, uniform 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, reusing in the afterwards short time did not need water filling.Starting electrical machinery 1 drives peripheral pump and centrifugal pump coaxial rotating 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 malleation, greatly reduces net positive suction head, and peripheral pump is exported from the water outlet high efficiency.The present invention adopts coaxial bilobed wheel structure, except structure is simple, compact, easy for installation, also significantly reduces axial force, is conducive to the running of mechanical seal, improves sealing effect, avoids leaking and causes motor 1 to damage.Another improvement of the present invention is swirl vanes 9 open architecture as shown in Figure 3, Figure 4, uniform radial blade is except easily shaping on the circumference, also has preferably particle-resistant impact capacity, this improves the working life of greatly improving swirl vanes 9, strengthen the reliability that Horizontal-type self-absorption centrifugal-peripheral combination pump uses, satisfied the supporting water pressure tank service condition of ocean going vessel and naval vessels fully.
