Abstract
The utility model discloses a kind of Stainless Steel Submersible Pump, comprise the pump housing and be arranged on the pump shaft in the described pump housing, described pump shaft is provided with some groups of impeller assemblies, described impeller assembly comprise be arranged on successively on described pump shaft with the axle sleeve of described pump shaft synchronous axial system and impeller, the bearing matched with described axle sleeve is arranged with outside described axle sleeve, described bearing is fixed in the described pump housing, mutually rotates with described axle sleeve; By seal ring seal that DuPont material is made between described impeller and the described pump housing; The described pump housing is the cylinder be made up of stainless steel material, and the diameter of itself and described impeller delivery position is greater than the diameter at all the other positions.The seal ring that DuPont material is made is set in the utility model between impeller and the pump housing, by seal ring seal impeller, the space between seal ring and impeller can be reduced to greatest extent, leakage rate is reduced, improve pump efficiency, meanwhile, the noise that the seal ring that DuPont material is made produces when can effectively reduce wheel rotation.
Description
Technical field
The utility model relates to a kind of pump and manufactures field, specifically a kind of submersible pump of more piece.
Background technique
Casting submersible pump is by motor and pump housing direct connection, water pump complete machine pulls the plug and carries out aspirating and carrying a kind of instrument of water, be generally used for and extract underground water from deep-well, also can be used for the water lift engineerings such as river, reservoir, water channel, be also widely used in farmland discharging-irrigating, industrial and mining enterprise, urban water supply and sewerage and sewage treatment etc. now.
Motor, the water pump of casting submersible pump vertically connect, and run, walked the high temperature produced in running by the fluxion strap of water in water, safely, reliably.But existing submersible pump is comparatively large due to the space between the pump housing and impeller, causes leakage rate excessive, has had a strong impact on the efficiency of submersible pump.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides a kind of Stainless Steel Submersible Pump efficiently.
Technological scheme: Stainless Steel Submersible Pump described in the utility model, comprise the pump housing and be arranged on the pump shaft in the described pump housing, described pump shaft is provided with some groups of impeller assemblies, described impeller assembly comprise be arranged on successively on described pump shaft with the axle sleeve of described pump shaft synchronous axial system and impeller, the bearing matched with described axle sleeve is arranged with outside described axle sleeve, described bearing is fixed in the described pump housing, mutually rotates with described axle sleeve; By seal ring seal that DuPont material is made between described impeller and the described pump housing; The described pump housing is the cylinder be made up of stainless steel material, and the diameter of itself and described impeller delivery position is greater than the diameter at all the other positions.
The utility model further preferably technological scheme is, the feed-water end of described pump housing bottom is fixed by bolt and motor, and the coupling of described motor is connected with described pump shaft by the flat key being arranged on pump shaft lower end.
Preferably, the upper end of the described pump housing with go out water pump shell and be connected, described in go out in water pump shell the safety check being provided with anti-backflow.
Preferably, described bearing is Tungsten carbite bearing.
Preferably, the diameter of the described pump housing and described impeller delivery position is a bit larger tham the diameter of described impeller, and the diameter at all the other positions is less than the diameter of described impeller.
Beneficial effect: the seal ring that DuPont material is made is set in (1) the utility model between impeller and the pump housing, by seal ring seal impeller, the space between seal ring and impeller can be reduced to greatest extent, leakage rate is reduced, improve pump efficiency, meanwhile, the noise that the seal ring that DuPont material is made produces when can effectively reduce wheel rotation; (2) pump housing all steel of the present utility model manufactures, lightweight, installs, uses, simply easy to maintenance, and floor space is little, does not need to build pump house; (3) the utility model arranges Tungsten carbite bearing, utilizes the effect of the low coefficient of friction of Tungsten carbite bearing, reduces the grating between axle sleeve and bearing and Rack, greatly reduces noise pollution; (4) diameter of the pump housing of the present utility model and described impeller delivery position is a bit larger tham the diameter of described impeller, and the diameter at all the other positions is less than the diameter of described impeller, reduces the leakage rate of the pump housing further, improves pump efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of Stainless Steel Submersible Pump described in the utility model.
Embodiment
