Abstract
The utility model relates to a submerged pump with an axial seal structure, solving the problem of the axial seal of the submerged pump, and comprising a motor, a machine base, a bearing, a double mechanical sealing mechanism, a front end cap, a pipe connection, an oil chamber, a pump body, a sealing ring, a pump cover, an impeller, a bottom plug and a bottom cover, wherein, the position of a shaft hole of the motor on the pump cover is provided with a concave chamber which is provided with a shaft sealing ring whose inner ring surface is in movable fit with a shaft of the motor; a V-shaped or a convex-shaped annular groove is arranged on the surface, of the shaft sealing ring, which is close to the impeller. The utility model has the advantages of good axial tightness, high delivery lift, big water flow, less power consumption, large quantity of pumped water, simple structure and long service life.
Description
The utility model relates to a kind of submersible pump, particularly has the submersible pump of axial seal structure.
Existing submersible pump mainly comprises motor, support, bearing, double mechanical seal mechanism, front cover, pipe joint, grease chamber, the pump housing, seal ring, pump benefit, impeller, bottom plug, end cover.Infiltration, particularly motor shaft to infiltration, be the subject matter that existing submersible pump exists, because the employed condition difference of submersible pump, as the motor shaft of the submersible pump height difference to the water surface, the hydraulic pressure that is subjected in the motor shaft place of submersible pump is also different, causes burning of motor, hydraulic pressure is high more, and the osmotic force of water is just strong more.Add at submersible pump and open when drawing water, during impeller high speed rotating on the motor shaft end, in the pump housing, produce a high pressure, the easier gap by axle of water in the pump housing is infiltrated.
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of under the high situation of water pressure, and motor shaft is to good seal performance, the submersible pump with axial seal structure of long service life.
For realizing the purpose of this utility model, the submersible pump of this axial seal structure, comprise motor, support. bearing, double mechanical seal mechanism, front cover, pipe joint, grease chamber, the pump housing, seal ring, pump cover, impeller, bottom plug, end cover, motor axis hole place on pump cover is provided with a cavity, is provided with Simmer ring in cavity, cooperating for movingly between the axle of the inner ring surface of Simmer ring and motor.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is an I enlarged view among Fig. 1.
Fig. 3 is the local figure of the sealing configuration of Simmer ring and motor shaft.
Fig. 4 is the local figure of the another kind of form of the sealing configuration of Simmer ring and motor shaft.
Below in conjunction with accompanying drawing one of them embodiment of the present utility model is described in further detail:
As shown in figs. 1 and 2, the submersible pump of axial seal structure has motor (1), support (2), bearing (3), double mechanical seal mechanism (4), front cover (5), pipe joint (6), grease chamber (7), the pump housing (8), seal ring (9), pump cover (10), impeller (11), bottom plug (12), end cover (13), Simmer ring (15), motor (1) is fixed on the interior bearing (3) of support (2), between front cover (5) and pump cover (10), be provided with ring-type grease chamber (7), between the axle of grease chamber (7) and motor (1), be provided with double mechanical seal mechanism (4), impeller (11) is arranged between the pump cover (10) and the pump housing (8), be fixed on axle (18) end of motor (1), on the pump housing (8), be provided with end cover (13), on the end cover (13) water inlet (14) is arranged, be used to stop foreign material, prevent that bigger foreign material from sucking in the pump housing (8), is provided with bottom plug (12) on the pump housing (8) water intake.Be respectively arranged with seal ring (9) between support (2), front cover (5), pump cover (10), the pump housing (8), sealing circle (9) is to prevent that the gap that produces between each parts from can leak.For preventing that more effectively sealing is penetrated in the support between motor shaft and the pump cover, motor (1) axis hole place on pump cover (10) is provided with a cavity (16), in cavity (16), be provided with back pressure type Simmer ring (15), the back pressure type Simmer ring adopts the high-quality abrasive rubber to make, simple in structure, easily change.Be provided with annular groove (17) at back pressure type Simmer ring (15) by on the face of impeller (11).Groove (17) both can be " V " word shape, can be " protruding " word shape again, as shown in Fig. 3 and 4.This design can make water pressure energy fully enter into the inside of back pressure type Simmer ring (15) by groove (17), and it is expanded outwardly, and enlarges the deformation band of back pressure type Simmer ring (15).And when motor rotates, the impeller extruding that water in the pump housing is rotated, can produce certain hydraulic pressure again, back pressure type Simmer ring (15) leans on the face of impeller (11) owing to be subjected to the pressure of water, force Simmer ring to produce distortion, make it to be close to the sealing surfaces of pump cover and motor shaft, the interior ring of back pressure type Simmer ring can diminish, and reduces with the gap of motor shaft.Hydraulic pressure in the pump housing is big more, the distortion of back pressure type Simmer ring is big more, also just more little with the gap of motor shaft, trend towards the drive fit state, the waterproof sealing of submersible pump is just good more, thereby has guaranteed that effectively the water in the submersible pump pump housing can be because of the increase of water pressure from axially in axle seal in motor.For improving the working life of submersible pump, on the inner ring surface of Simmer ring (15), be provided with packing groove (19), in packing groove (19), be provided with sealing wear resistant filler (20), strengthen sealing and scurf resistance between Simmer ring and the motor shaft.After submersible pump quits work, because of pond or outlet pipe top to a drop is arranged between the submersible pump, so the hydraulic pressure in the pump housing still exists, the pressure that acts on the back pressure type Simmer ring back side is not removed immediately, the back pressure type Simmer ring is still keeping excellent sealing performance, only remain hydraulic pressure in the pump housing when dropping to certain value, the residual water pressure that the back pressure type Simmer ring just can overcome in the pump housing restores, be state movingly with motor shaft, utilize the submersible pump starting of working for the second time, remaining press water keeps off in the pump housing by the seal ring of double mechanical seal mechanism, because the hydraulic pressure in the pump housing reduces greatly, even this moment, the sealing of back pressure type Simmer ring was removed, remaining press water also can't pass the seal ring of double mechanical seal mechanism and enter in the motor.
The immersible pump of the utility model axial seal structure owing to adopt back pressure type Simmer ring structure, have simple in structure, Axial seal is directly proportional with hydraulic pressure, and namely hydraulic pressure is more big, and axial sealing property is more good characteristics just, have the lift height, go out Water is violent, little power consumption, and pump-out is big, the advantage of long service life.
