Abstract
The utility model provides a high-efficiency sealed submersible pump, which is characterized in that the mechanical seal assembly with double end carbon of the submersible pump adopts corrosion-resistant shaft sleeve made of stainless steel to replace the original rubber shaft sleeve with embracing shaft transmission; the original one spring is changed into two springs; a moving ring, a rotating shaft and the corrosion-resistant shaft sleeve are sealed by sealing rings; the corrosion-resistant shaft sleeve and a major-diameter shaft shoulder of the rotating shaft are sealed by a sealing ring. The utility model has the advantages of long service life, stable operation, simple structure, good sealing lubricity, convenient maintenance, etc., and is suitable for various submersible pump submerged pumps.
Description
The utility model belongs to a kind of improved submersible pump, particularly a kind of good airproof performance, the efficient sealed submersible pump of long service life.
Submersible pump, as the term suggests be the suction pump of in water, working, be usually used in the rural area draw water water drainage, irrigate and aspirate sewage or industrial wastewater.Submersible pump is simple in structure, only is made up of submersible motor, rotating shaft, water pump and mechanical seal assembly, but sealing problem is difficult to solution always, should prevent that the liquid of being taken out from entering between water pump and the motor in the sealed type oil pocket, prevents that again the oil of oil pocket from entering in the motor.In prior art, generally adopt double mechanical seal to solve, the structure of this mechanical seal assembly as shown in Figure 1, by in the stationary ring 3 and stationary ring seal ring 2, the rotating shaft 9 that are arranged on motor 1 and water pump 8 bearing faces seize transmission rubber axle sleeve 7, place the spring 6 on the seize transmission rubber axle sleeve 7 and form with 3 contacts of two stationary rings and two rotating rings 4 that are connected with spring 6 and ring seat 5 respectively.This double mechanical seal assembly is to rely on stationary ring seal ring 2, seize transmission rubber axle sleeve 7 and rely on spring 6 pressure to make rotating ring 3 be close to stationary ring 3 end faces contact the oil film that produces between end face with two and realize that radial seal and axial end seal.This sealing mechanism can play the better seal effect at the effect initial stage, but time one is long, because the complexity of institute's pumping liquid medium is easy to make seize transmission rubber axis 7 covers aging, in case occur agingly influencing the transmission of spring and making seal failure with regard to direct.In addition, the pressure that the sealing of two end faces all produces by same spring very much, if wherein the contact of end face was on one side lost efficacy, whole sealing was just lost efficacy.Therefore, this mechanical seal exists always lost efficacy soon, outside the high deficiency of repair rate, directly had influence on the working life of submersible pump.
The purpose of this utility model is to make improvements at the deficiency of existing immersible pump double mechanical seal, provides a kind of effective sealing time long, the efficient sealed submersible pump that repair rate is low.
Description of drawings:
Fig. 1 is the partial sectional view of existing submersible pump mechanical seal part.
Fig. 2 is the partial sectional view of the utility model mechanical seal part.
Task of the present utility model realizes by this way: as shown in Figure 2, and this practicality Novel main is close by submersible motor 1, water pump 8, rotating shaft 9, grease chamber 10 and Double End machinery The envelope assembly forms, this double mechanical seal assembly include stationary ring 3, stationary ring seal washer 2, Rotating ring 4, rotating seat 5 and spring 6 is characterized in that rotating shaft 9 is one and has size diameter Multidiameter, at path section cover an anti-corrosion axle sleeve 11 is arranged, anti-corrosion axle sleeve 11 with turn to Path section between the axle 9 big footpath sections is provided with sealing ring 12, and spring 6 is two, with anti-corrosion The convex shoulder of axle sleeve 11 is spacingly to be connected with two rotating seats 5 respectively, two rotating rings 4 with turn to Be provided with sealing ring 13 and 14 between axle 9 and the anti-corrosion cover 11.
The purpose of this utility model also can adopt following measure to realize: described anti-corrosion axle sleeve 11 can be to use corrosion-resistant nylon, and corrosion resistant metal is made, but the most handy stainless steel manufacturing.Described two springs 11, the spring 11 of water pump end is preferably levoform, and the spring of motor side is the dextrorotation formula, can improve the tension force of spring.
Compared with the prior art the utility model has following advantage:
1,, exists aging and cause the problem of premature failure, and adopt the anti-condom 11 of stainless steel, liquid body medium influence not, the working life that can improve the double mechanical seal assembly greatly because cancellation seize transmission rubber axle sleeve.
2, owing to adopt two springs 6, work alone separately, therefore the seal face of any one side damages, and does not also influence the mechanical seal work of opposite side, has improved working life.
In addition, the utility model also have simple in structure, seal lubrication good and advantage such as convenient for maintaining maintenance.
The utility model mainly is applicable to submersible pump.
Claims (2)
1, a kind of efficient sealed submersible pump, mainly by submersible motor (1), water pump (8), rotating shaft (9), grease chamber (10) and the close assembly of Double End machinery are formed, this double mechanical seal assembly includes stationary ring (3), stationary ring seal washer (2), rotating ring (4), rotating seat (5) and spring (6), it is characterized in that rotating shaft (9) is a multidiameter shaft with size diameter, on the path section, be with an anti-corrosion axle sleeve (11), on the path section between anti-corrosion axle sleeve (11) and the big footpath of rotating shaft (9) section, be provided with seal ring (12), spring (6) is two, with the convex shoulder of anti-corrosion axle sleeve (11) is spacingly to be connected with two rotating seats (5) respectively, is provided with seal ring (13) and (14) between two rotating rings (4) and rotating shaft (9) and anti-corrosion cover (11).
2, submersible pump according to claim 1 is characterized in that anti-corrosion cover (11) is to make with stainless steel.
