Abstract
The invention discloses a molten salt pump, which consists of a pump cover, an impeller A, a pump body A, a stuffing device, a bearing box component and so on, wherein the pump body A is provide with two impeller cavities, and the impeller A is arranged on a lower cavity and an impeller B is arranged on an upper cavity; a pump body B is connected with the pump body A through bolts, and the left of the other end of the pump body B is communicated with an output tube while the right is passed through by a pump shaft; a joint tube A and a joint tube B are arranged on the pump shaft; the output tube, the joint tube A and the joint tube B are wrapped by clamp sleeves; an upper end of the pump shaft is provided with the stuffing device and the bearing box component in a bearing frame in sequence; and the top end of the pump shaft is provided with a shaft joint. The molten salt pump uses secondary impellers to solve the problem of low single-level pump lift of the pump and improve the efficiency of the pump. Double volute casing pump body eliminates a radial force, and a middle joint tube of the pump and an outlet of the pump use clamp sleeves which are filled with heating water to ensure the consistent thermal expansion of the output tube, the pump shaft and the middle joint tube, thereby improving the service life of the device.
Description
Technical field: the present invention relates to pump, particularly relate to a kind of pump for liquid salts.It is applicable to delivery temperature about 450 ℃, and proportion is at the high-temperature molten salt of 1.8-2.0.
Technical background: present pump for liquid salts, the single-stage lift of pump is low, pump bulky, radial force is big, and the working life of pump is low.
Summary of the invention: purpose of the present invention will provide a kind of pump for liquid salts exactly, it can overcome the problem that present pump for liquid salts exists well, the object of the present invention is achieved like this, a kind of pump for liquid salts is by pump cover, impeller A, pump housing A, impeller B, pump housing B, chuck, filler device, fuel tank, bearing box assemblies etc. are formed, it is characterized in that: pump housing A is provided with two impeller cavities, the cavity of resorption setting be impeller A, impeller A radially is positioned on the pump shaft by key, axially lock by impeller nut, and pump cover is connected with pump housing A by bolt, epicoele is provided with impeller B, impeller B radially is positioned on the pump shaft by key, and by bolt pump housing B is connected with pump housing A, the other end left side of pump housing B communicates with output tube and by Bolt Connection, the right is passed by pump shaft; Described pump shaft is provided with to be taken over A and takes over B, chuck is wrapped in output tube, adapter A and adapter B, the upper end of pump shaft is disposed with the bearing box assembly in filler device and the bearing bracket stand, is provided with fuel tank on the right of bearing bracket stand, and the top of pump shaft is provided with coupling.The present invention adopts sencond stage impeller, has solved the low problem of single-stage lift of pump, has reduced the volume of pump, has improved the efficient of pump.The double volute pump housing has been eliminated radial force, reduces the vibration of pump, and pump middle adapter and pump discharge adopt chuck, is full of to add hot water between chuck, to guarantee the thermal expansion unanimity of output tube, pump shaft, middle adapter, the working life of having improved equipment.
Description of drawings: Fig. 1 is a structural representation of the present invention;
1. pump cover, 2 impeller nuts, 3 chomas, 4 impeller A, 5 pump housing A, 6 envelope I, 7 times protective shaft sleeve I, 8 impeller B, 9 pump housing B, 10 chomas, 11 times protective shaft sleeve II, 12 take over A, 13 jack shaft sheaths, 14 interstage bushings, 15 intermediate bearing block sets, 16 take over B, 17 packing sleeves, 18 base plates, 19 filler cavitys, 20 Glands, 21 pump shafts, 22 fuel tanks, 23 bearing bracket stands, 24 bearing box assemblies, 25 coupling, 26 motor cabinets, 27 chucks.
Embodiment: the invention will be further described for following knot box accompanying drawing;
In the drawings, a kind of pump for liquid salts is by pump cover 1, impeller A 4, pump housing A5, impeller B8, pump housing B9, chuck 27, filler device, fuel tank 22, bearing box assembly 24 is formed, it is characterized in that: pump housing A5 is provided with two impeller cavities, the cavity of resorption setting be impeller A 4, impeller A 4 radially is positioned on the pump shaft 21 by key, axially by impeller nut 2 lockings, and pump cover 1 is connected with pump housing A5 by bolt, epicoele is provided with impeller B8, impeller B8 radially is positioned on the pump shaft 21 by key, and by bolt pump housing B9 is connected with pump housing A5, the other end left side of pump housing B9 communicates with output tube and by Bolt Connection, the right is passed by pump shaft 21; Described pump shaft 21 is provided with to be taken over A12 and takes over B16, chuck 27 is wrapped in output tube, adapter A12 and adapter B16, the upper end of pump shaft 21 is disposed with the bearing box assembly 24 in filler device and the bearing bracket stand 23, be provided with fuel tank 22 on the right of bearing bracket stand 23, the top of pump shaft 21 is provided with coupling 25.During concrete enforcement, when coupling connects energising with motor shaft after, pump shaft rotation stably under bearing box assembly and the supporting of intermediate bearing block set, at this moment medium sucks by impeller A, impeller B, B exports to output tube by the pump housing, because delivery temperature is about 450 ℃, proportion is at 1.8-2.0, for guaranteeing the thermal expansion unanimity of output tube, pump shaft, adapter, adopt chuck at pump middle adapter and pump discharge, between chuck, be full of and add hot water, to guarantee its unanimity of being heated, thereby improve the working life of equipment, saved cost.Adopt sencond stage impeller simultaneously, solved the low problem of single-stage lift of pump.
