Embodiment

In order to make up the large phenomenon of noise due to the existing mechanism of pump, the catalase hush tube containing aluminium dioxide of a kind of improvement for motor provided by the invention is packed in machine, make waste gas by muffler assembly and catalyst hush tube (69), again by there being the whole protective housing that covers pump of noise elimination effect, and from its gap or aperture gap discharge.Whole centrifugal pump, or together with the protective housing of motor outer cover, or with double-deck blowing shell, liner foamed plastics, or use other materials.

Centrifugal pump prestart, must can start, otherwise the pump housing can not complete imbibition, and cause pump housing heating and vibrations to after being full of water in pump case, not go out water generates idle running, form air sinuses, cause the equipment accidents such as water pump damage.

Because the present invention relates to a kind of field that is suitable for, building site, garden, park and road side etc. are without electric field centrifugal pump used, the water pump class that belongs to universal machine product, especially a kind of with driving machine, as motor, the single-cylinder air-cooled petrol engine 139F of the mini four-stroke type that particularly contains the Carburetor of internal spiral whirlpool nozzle, or by the Carburetor that contains internal spiral whirlpool nozzle and the single-cylinder air-cooled petrol engine 1E34 of the small two-stroke type that improves many scavenging ports, to come the two ends of containing that direct connection drives are at a high speed disk planes, interior concave bottom is parabolic function face, and blade both sides are gradually to open function face, and blade both sides are interior thin and outer thick impellers, two-way left and right is even revolves labyrinth seal with containing, and contain eccentric outlet, and the northern hemisphere is counterclockwise to the shell of streamline rib, and contain outlet chamfering, and the centrifugal pump of the spiral case of the counterclockwise non-Archimedes's function line flowing in the northern hemisphere, perhaps can say, start a kind of new technical field that has swirl sprayer engine direct to be associated with high speed function impeller and occasionally to revolve the centrifugal pump in labyrinth.

Motor direct connection centrifugal pump, portable because of it, be widely used in field, building site, garden, park and road side etc. without electric field institute.Its low vibratility and low noise, if consider the foamed plastics of plus-minus vibration around, can have certain curative effect; And vibration and the very large root of noise be not only in precision and the form and position tolerance of power and pump, and be that mechanism coordinates with the harmony of motor, low vibration and the low emission of pursuit pump are in fact hard nut to cracks of leaving over for a long time.Adopt two stroke engine can improve power per liter more than 50% with respect to four stroke engine, but will take measures in discharge, this is a part of problem of the present invention; Motor direct connection centrifugal pump is portable dam, wishes that power is gently little; If exert oneself less by four stroke engine; If with pressurized machine, volume is large; If with the diesel engine easy dirty dirty person.Since motor direct connection centrifugal pump comes out, the structure of the core component impeller of its work is just based upon on the theoretical foundation of a hypothesis always, make exactly the blade quantity of impeller infinitely many, the thickness of blade is infinitely small, thereby eliminates the eddy current of water in impeller; But in fact the poor efficiency of water pump is that a gram sight exists.The shell of traditional direct-connected water pump, as Figure 12, Figure 13, Figure 14, shown in Figure 15, its water outlet is placed in the middle, and in the middle part of it, a plurality of ribs of water intake are not fusiform, so all smooth water outlet is had to certain retardation.The spiral case of traditional direct-connected water pump, two water outlet is section, if add chamfering, water outlet is just more level and smooth, and reduces unexpected section and the vortex that forms.The blade of traditional direct-connected water pump, as shown in Figure 22, Figure 23, Figure 24, Figure 25, the thickness of its blade is the same, this is disadvantageous, more outer i.e. larger radius blade stressed increasing, and current direction does accelerated motion is outward should more outer blade thicker better.The water pump spindle of traditional direct-connected water pump, as shown in Figure 29, Figure 30, Figure 31, is that extra rotary inertia is large with the external flange of two bolt connecting engine output shafts on regular way orchid, and easily inclined to one side head tremor pendulum.The conventional Compress Spring mechanical single seal of traditional direct-connected water pump, its axial pressure is larger.Also have spiral labyrinch seal also to cry the spiral seal of composite straight-through shape, be processed with respectively the multiple thread of opposite direction on axle surface with cover internal face, the tooth of internal and external threads is intersecting across gap.When axle rotates, fluid eddy generation friction between the contrary spiral of rotation direction, produces pressure head and overcomes leakage.Rotating speed is higher, and leakage rate is fewer, and it is applicable to low viscosity fluid; If be further improved to, contain that two-way left and right is even revolves labyrinth seal on this basis, and with addition of also sealable O RunddichtringO of static state, or other type is mainly static seal ring, also can be used on water pump.
