Abstract
The utility model discloses a space guide blade type long shaft pump depressurizing structure, which comprises a space guide blade, a pump shaft, a bearing component, a sealing component, a protective pipe, a connecting pipe and a depressurizing pipe, wherein the pump shaft is matched with and positioned in the interior of the space guide blade; the space guide blade, the protective pipe and the connecting pipe are connected into a whole through bolts; the sealing component is matched with the positioned together with the pump shaft and the space guide blade through bolts; and the depressurizing pipe is arranged on the space guide blade. A depressurizing seal cavity and a depressurizing hole are arranged on the space guide blade. The space guide blade type long shaft pump depressurizing structure disclosed by the utility model is simple in structure, low in fabrication cost and simple and convenient to install and maintain, improves the sealing performance and prolongs the service life of the sealing component, effectively stops liquid from rising up along the pump shaft to be pressurized, and ensures that the liquid does not enter the bearing component, thereby achieving the effect of protecting the bearing component and the pump shaft, improving the operating performance of a pump unit, and prolonging the service life of the pump unit.
Description
Technical field
The utility model relates to a kind of pressure reduction structure, relates in particular to a kind of spatial guide blade formula major axis pump pressure reduction structure.
Background technique
At present; Existing space stator formula major axis pump be the inlet segment of suction bell formula bottom; Liquid gets into through the inlet segment horn mouth; Make the pumping chamber runner of liquid between spatial guide blade, connecting tube and pillar realize pumping of liquid through the impeller rotation to its workmanship, the spatial guide blade inner chamber is provided with seal arrangement and sub-propeller decompressor.As long axis of the end portion of the guide vane pump space immersed in the pumped liquid below the long-term, so the guide vane cavity space corrosion and liquid within the space debris will be deposited in the lumen of the guide vanes.When the pump group is moved, the highly pressurised liquid that impeller work produces, this highly pressurised liquid reduces pressure to it through sub-propeller.As Vice-speed rotating impeller, guide vane cavity space will produce high pressure liquid rotation vane cavity due to space corrosion and liquid is deposited within the debris, make these deposits occur on the inner wall of the guide vanes space erosion speed rotation, thus destroying the normal use of the guide vanes space, and vice impeller decompression are poor, which causes these deposits with high pressure liquid into the seal assembly, thus undermining the pump shaft and bearing assembly performance, affecting the normal operation of pump and reduce its life.Therefore need a kind of more effective pressure reduction structure.
Summary of the invention
The purpose of the utility model is to overcome the deficiency in the problems referred to above, and a kind of spatial guide blade formula major axis pump pressure reduction structure is provided.
For solving the problems of the technologies described above; The technological scheme of the utility model is: a kind of spatial guide blade formula major axis pump pressure reduction structure; Comprise spatial guide blade, pump shaft, bearing unit, black box, pillar, connecting tube, relief pipe, said pump shaft is positioned in the spatial guide blade through the bearing unit cooperation; Said spatial guide blade, pillar and connecting tube are connected as a whole through bolt; Said black box is positioned at pump shaft, spatial guide blade cooperation through screw; Said relief pipe places on the spatial guide blade.
Spatial guide blade is provided with reduced pressure sealing chamber and vent.
The utility model fabricating cost simple in structure is low; Installation and maintenance are simple and convenient, and water pump can make the pressure self balancing of spatial guide blade inner chamber liquid and spatial guide blade outer wall liquid reach under the condition attitude through this pressure reduction structure and work, promoted the sealability and the working life of black box; And then effectively stop liquid along pump shaft rise pressure; Guarantee that liquid that can not gets into bearing unit, reach the effect of protection bearing unit and pump shaft, improved pump group usability, prolonged the working life of pump group.
