Description of drawings: 1, impeller 2, suction inlet flange 3, front plate 4, outlet(discharge) flange 5, pump case 6, mechanical sealing element 7, rear plate 8, cushion block 9, bearing housing 10, leg 11, pump shaft 12, coupling 13, motor 14, base 15, water conservancy diversion bend pipe 16, slinger ring 17, cooling water chamber
Embodiment
Below be to describe technological scheme of the present invention in detail by accompanying drawing.
As shown in Figure 1, a kind of efficient graphite axial-flow pump of the present invention, form by base 14, motor 13, bearing housing 9, pump case 5 and impeller 1, wherein, described motor 13 utilizes leg 10 to fixedly connected with described base 14 with described bearing housing 9, described pump case 5 both sides utilize front plate 3 and rear plate 7 to clamp respectively and fixedly connected with base 14, utilize coupling with rubber type element 12 to be connected between described motor 13 and the described bearing housing 9, the connection of realization elasticity.Described bearing housing 9 is bolted to connection in rear plate 7, and be provided with a plurality of cushion blocks 8 between rear plate 7 and the bearing housing 9, make and formed spacing between rear plate 7 and the bearing housing 9, on the pump shaft 11 at this spacing place, be provided with a rubber slinger ring 16, when mechanical seal is worn and torn or cause medium or mechanical lubrication cooling water to reveal unusually, just see leak case by this spacing, and rubber slinger ring 16 is during with pump shaft 11 rotation, the liquid of revealing can be blocked and throws away again, be unlikely to enter bearing housing 9.There is the water conservancy diversion bend pipe 15 of 90 degree in footpath at a gulp described pump case 5 inside, and described pump case 5 adopts graphite to be processed by five-axle number control machine tool.Described impeller 1 core has screw thread, is convenient to be connected and driving torque with pump shaft 11, and described impeller 1 adopts whole graphite to be processed by four-shaft numerically controlled extra bed, and the blade shape of impeller 1 and propeller cavitation are similar.One double mechanical seal spare 6 is arranged on the hole at described impeller 1 afterbody and described pump case 5 rear portions.
Because the suction inlet honeycomb duct of pump case 5 is longer, adopt steel suction inlet flange 2 to be connected with described conduction pipe 15, pump case 5 has described front plate 3 and rear plate 7 to clamp by screw rod, become an integral body, delivery side of pump is provided with outlet(discharge) flange 4 in order to be connected with pipeline, and be fixed on front plate 3 and the rear plate 7, so just formed a pump housing, front plate 3 and rear plate 7 respectively have two ears, so that be installed on the described base 14.Described bearing housing 9 bottoms are provided with a cooling water chamber 17.
Working principle of the present invention:
When motor 13 rotates, drive pump shaft 11 runnings by coupling 12, because impeller 1 adopts with pump shaft 11 and is threaded, thereby the moment on the pump shaft 11 passes to impeller 1 by the screw thread of axle 11 front ends, thus impeller 1 rotation, and the blade on the impeller 1 is starched shape in the shape of a spiral, during rotation conveying liquid is done work, moving after forcing liquid by forward direction, upwards is that the pump discharge direction flows along water conservancy diversion bend pipe 15, to reach the purpose of carrying liquid again.
In the hole at impeller 1 afterbody and pump case 5 rear portions, double mechanical seal spare 6 is housed, the 6 inner chamber water flowings of this double mechanical seal spare, the Sealing 6 of front end separates the medium of pump chamber and the water in the Seal cage, the Sealing 6 of rear end separates the water in the Seal cage and the external world, water enters from the Seal cage bottom of a side of pump, discharge on top, thus sealing surface lubricated and cooling machinery.
Because axial-flow pump is when carrying high-temp liquid, pump shaft 11 can be with heat transfer to bearing housing 9, cause lubricating oil temperature rising in the bearing housing 9, and bearing also can generate heat in the running, the bearing of running so at high temperature can shorten working life, therefore, can take away the heat of lubricant oil in the bearing housing 9 after cooling water chamber 17 water flowings of bearing housing 9 bottoms, thereby the temperature when having reduced bearing operation prolongs its working life, and cooling water is introduced into the cooling water chamber 17 of bearing housing 9, enter the mechanical seal chamber after coming out again, can discharge after going out Seal cage, also can send into total return pipe, realize recycling.Because the property of graphite makes the graphite axial-flow pump high temperature resistant, corrosion-resistant, long service life.
