Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, handy type through-flow pump of the present utility model comprises inlet segment 1, diffuser 2, impeller 3, sealed member 4, main shaft 5, permanent magnet frequency conversion motor 6, externally connected pipe 7, water exit end 8, with motor casing 9, diffuser 2 comprises diffuser inner casing and diffuser shell, flow passage chamber is formed between the inner casing of this diffuser and shell, diffuser inner casing connects motor casing 9, permanent magnet frequency conversion motor 6 is located in motor casing 9, permanent magnet frequency conversion motor 6 connects main shaft 5, main shaft 5 connects impeller 3, sealed member 4 is set between main shaft 5 and diffuser inner casing, inlet segment 1, diffuser shell, externally connected pipe 7 and water exit end 8 are linked in sequence successively, to form flow passage chamber, the blade of impeller 3 stretches to the flow passage chamber between inlet segment 1 and diffuser 2.Because this through-flow pump have employed, power is high, volume is little, lightweight permanent magnet frequency conversion motor 6, and correspondingly, pump body structure layout has done innovative design, and make this through-flow pump overall structure compacter, volume is less, and weight is lighter.
The working principle of this through-flow pump is: start permanent magnet frequency conversion motor 6, motor is by main shaft 5 Driving Torque, and main shaft 5 impeller 3 rotates, and medium is after the horn mouth intake impeller 3 of inlet segment 1, flowing medium obtains supercharging, fluid evenly leads through impeller 3, and due to the blade rotary of impeller 3, the velocity of medium on blade top will increase, and the flow velocity of bottom will reduce, according to bernoulli's equation, the local pressure that flow velocity is large is little, and the little local pressure of flow velocity is large.Because the change of speed this around blade and pressure just creates a kind of thrust upwards, this power is called lift, and medium then enters in flow passage chamber along with this strand of lift, by being discharged by water exit end 8 after diffuser 2 and externally connected pipe 7.
The compact structure of diffuser 2, be fixedly connected with permanent magnet frequency conversion motor 6, have the drainage lumens effect of bearing (ball) cover, mechanical seal chamber, flowing medium concurrently, make through-flow pump overall structure easier to be compact, externally connected pipe 7 can also utilize fluid to flow in pipe while being led by flowing medium and cool the motor of heating, and motor self is maintained.
Permanent magnet frequency conversion motor 6 comprises stators and rotators, rotor adopts Ru-Fe-Mn rare earth magnetic steel, this rotor is set to 8 grades, stator adopts supporting double-deck coiling to form, and its copper factor reaches more than 80%, can permanent magnet frequency conversion motor be made to reach volume little, high-power effect, such as, ordinary power is that the motor of 15KW is about 110Kg, and the permanent magnet frequency conversion motor weight that same power is 15KW is only 17Kg.
Impeller 3 is diagonal flow type higher specific speed impeller, and its liquid medium flows out impeller along the direction that axis tilts, and the impeller flow of this mode is large, and power loss is little, and the specific speed of impeller is high, and when rotating speed is 3100n/min, its flow can reach 1500cm
2, lift is 20m.
As shown in Figure 1, inlet segment 1 is flaring pipe, and the osculum of tubaeform suction connects diffuser 2, and its large mouth is water intake, the efficient suction stream body medium of flaring intake pipe energy, thus flowing medium can be made to have enough energy.
As shown in Figure 1, permanent magnet frequency conversion motor 6 is provided with electric motor end cap 12 near one end of water exit end 8, main shaft 5 is non-uniform shaft, large footpath section in the middle of main shaft 5 is connected with permanent magnet frequency conversion motor 6, the path section at main shaft 5 two ends is combined with clutch shaft bearing 10 and the second bearing 11 respectively, clutch shaft bearing 10 is fixed on diffuser inner casing, second bearing 11 is fixed on electric motor end cap 12, by arranging electric motor end cap 12, motor seal is isolated with tube fluid, in order to avoid enter fluid in motor and impaired, the main shaft 5 of variable cross section can change torque, thus play speed changing effect, the impeller be connected with main shaft 5 is made to have enough power rotating speeds, thus supercharging is carried out to the flowing medium entering impeller.
As shown in Figure 1, water exit end 8 comprises water exit end inner casing and water exit end shell, water exit end inner casing is connected with motor casing 9, water exit end shell is connected with externally connected pipe 7, and the inwall of water exit end inner casing and electric motor end cap 12 are closely fixed, by water exit end 8, the flow passage chamber in the pump housing and permanent magnet frequency conversion motor 6 are effectively isolated, protect motor further, flowing medium in the pump housing is discharged along the cavity between water exit end inner casing and shell, in the unlikely chamber entering motor part of inner casing buffer fluid medium of simultaneously water exit end, arrange rationally effectively, the circulate meeting flowing medium also protects motor.
As shown in Figure 1, Lubricants is marked with in cavity between main shaft 5 and diffuser 2, sealed member 4 adopts mechanical seal mode to the shaft sealing of main shaft 5 envelope, mechanical seal keeps sealing component to fit under the pressure of Lubricants and the elastic force effect of compensation mechanism, and be equipped with auxiliary seal and reach the gland seal device of Drain Resistance.Wherein, mechanical seal structure is existing mature technology, and this patent does not repeat to set forth.
The inlet segment 1 of this handy type through-flow pump, water exit end 8, diffuser 2, externally connected pipe 7 and motor casing 9 all adopt high tensile aluminium alloy, impeller 3 adopts stainless steel, its intensity and hardness satisfy the demands, the mechanical property of this pump is improved, and also reduces total volume and gross weight simultaneously, and its gross weight is only about 35Kg, compare traditional vane pump and through-flow pump more lightweight, make it without the need to also working in the water that all submerges, facilitate the emergent water drainage in low laying areas to use, reduce labor intensity.
It should be noted that, when carrying out draining lift and being less, this handy type through-flow pump can be used alone, when it is large that draining lift need be carried out, some this handy type through-flow pump head and the tail can be connected use, reach the object of remote drainage by supercharging step by step, substantially increase output lift, be both applicable to low-lying water drainage and be also applicable to urban road and pipe network draining and speedily carry out rescue work application.
In sum, a kind of handy type through-flow pump of the present utility model, power is large, and lift is large, and volume is little, lightweight, compact structure, and arrange rationally effectively, working efficiency is high, applied widely.
Finally illustrate: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
