A metal gasket (2) is sleeved between the motor rotor spindle (7) and the double-spiral sand throwing ring (3), the double-spiral sand throwing ring (3) is fixed through the metal gasket (2) on one end and a connecting flange (1) on other end, and then is fixed and sealed through a mechanical seal or a framework oil seal (4) inside the metal gasket. An abrasion-resisting pad (6) is fixed on the motor bearing seat, and the abrasion-resisting pad (6) is placed between the motor bearing seat and sand throwing blades on the double-spiral sand throwing ring (3).
Description
Technical field
The utility model relates to a kind of Submerged Motor Pumps, particularly a kind of Submerged Motor Pumps that can sand control.
Background technique
Submerged Motor Pumps was when being used for the large occasion of medium silt content in the past, because silt particle is easy to enter between rotor shaft and the motive sealing, make rotor shaft and sealing because of the Fast Wearing earlier period damage of silt particle, cause submersible motor to intake because of the sealing short term failure, thus motor damage.Shorten the working life of this machine, affected job schedule, also strengthened cost simultaneously.
Summary of the invention
For overcoming above defective, the purpose of this utility model provides a kind of sand control seal arrangement that has, long service life, the Submerged Motor Pumps that manufacturing efficiency is high, comprise motor, motor bearing seat and water pump, be provided with the sand control seal arrangement between motor and the water pump, described sand control seal arrangement mainly is comprised of double helix sand-throwing ring, sediment outflow circle and wear-resistant pad.To solve the problem of the Submerged Motor Pumps seal failure that existing Submerged Motor Pumps causes because of the Fast Wearing of silt.
To achieve these goals, the utility model has adopted following technological scheme: a kind of sand control Submerged Motor Pumps, comprise motor, motor bearing seat and water pump, between motor and water pump, be provided with the sand control seal arrangement, described sand control seal arrangement is provided with a double helix sand-throwing ring, described double helix sand-throwing ring is set on the rotor axis of electric, is fixed with the sediment outflow circle on the motor bearing seat, is provided with the gap between sediment outflow circle endoporus and the double helix sand-throwing ring cylindrical.
Cover has metallic shim between rotor axis of electric described in the utility model and double helix sand-throwing ring, and the double helix sand-throwing ring is fixed by the metallic shim of an end and the adpting flange of the other end, again by the mechanical seal in the metallic shim or outside framework oil seal fixing seal.One end outer periphery of described double helix sand-throwing ring is provided with gets rid of sand blade and twin-feed spiral groove, and the other end is provided with a boss, the curved transition in outer periphery of boss and double helix sand-throwing ring, and double helix sand-throwing ring inner circle is provided with a draw-in groove vertically.Be fixed with wear-resistant pad on the described motor bearing seat, described wear-resistant pad getting rid of between the sand blade on motor bearing seat and double helix sand-throwing ring.Sediment outflow circle endoporus and double helix sand-throwing ring cylindrical gap are 1～2mm.Getting rid of sand blade and wear-resistant pad gap on the described double helix sand-throwing ring is 2～3mm.
After adopting above technological scheme, the utility model has a double helix sand-throwing ring at the rotor axis of electric cover, rotor axis of electric drives the double helix sand-throwing ring and rotates, High Rotation Speed by the double helix sand-throwing ring, by the twin-feed spiral groove of its outer periphery with get rid of the sand blade, drive water flow rotary, form centrifugal force from inside to outside, silt particle is thrown away rotor axis of electric and double helix sand-throwing ring surface, reach the purpose of anti-sand wear.
