Abstract
The utility model relates to a long -axis submerged pump's sealing device. The sealed department that has mainly solved current long -axis submerged pump easily blocks the problem of dying and maintaining the difficulty. Bottom plate top is equipped with seal structure, and seal structure includes that condiment box and graphite packing pack, and the filler box passes through set screw fixed connection on the bearing box, and bearing box fixed connection is on the bottom plate, and an axle lower extreme is equipped with the location bush. This long -axis submerged pump's sealing system shifts up to the bottom plate top, replaces and the secret technical scheme who seals through the packing is sealed, has both played sealed effect, and the foreign particles who also avoids the medium to open gets into sealed, makes the sealed card die, and the bearing is dustproof simultaneously, increase of service life, and the sealing system shifts up the dismouting of being convenient for and maintains, reduces user's cost.
Description
Technical field
This utility model relates to long shaft submerged pump, is specifically related to the sealing device of a kind of long shaft submerged pump.
Background technology
Long shaft submerged pump is applicable to the multiple Korrosionsmediums such as conveyer belt granule, high viscosity, strong acid, alkali, salt, strong oxidizer, and the scope of application is the most extensive.Its structure is that motor is partially disposed on liquid level, and pump portion is placed under liquid level.Generally use mechanical seal in the market, the fault of machine seal face: abrasion, hot tearing, deformation, breakage；The fault of spring: relax, rupture and corrode；Mechanical seal often occurs vibrating, generates heat, faults such as causing dielectric leakage of wearing and tearing.
Pump is sealed by the form that this mechanical seal is placed in pump cover simultaneously, and owing to having the entrance of impurity in medium unavoidably, this structure can make machine envelope the most stuck, damages；Secret is sealed and placed in bottom it cannot be guaranteed that shaft concentricity so that pump shakes, and at the sealing structure of existing major axis slag slurry pump under liquid, time-consuming long, the maintenance difficult of maintenance trouble, causes customer using cost high.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides the sealing device of a kind of long shaft submerged pump, mainly solve the most stuck at the sealing of existing long shaft submerged pump and the problem of maintenance difficult, move in the sealing system of this kind of long shaft submerged pump above base plate, replaced by packing_seal and the technical scheme of secret envelope, both sealing function had been served, also the impurity particle avoiding medium to open enters at sealing, make sealing stuck, bearing is dust-proof simultaneously, increase the service life, sealing system is moved and is easy to dismounting maintenance, lower the cost of user.
This utility model be the technical scheme is that the sealing device of a kind of long shaft submerged pump, including axle and base plate, axle top connects motor, described base plate is arranged over sealing structure, described sealing structure includes filler casing and graphite packing filling, described filler casing is fixedly connected on bearing housing by location screw, and described bearing housing is fixedly connected on base plate, and described axle lower end is provided with location lining.
Described graphite packing filling is placed in stuffing box body and sealing.
Described graphite packing filling is arranged over gland, and gland is fixed on filler casing by alignment pin.
Described location lining is secured within pump cover, is provided with axle sleeve between location lining and axle, and described axle sleeve is fixed on axle, and described location sleeve inner surface is provided with bar-shaped trough, and described bar-shaped trough trench bottom is that globoidal structure is arranged.
The beneficial effects of the utility model are: owing to taking technique scheme, effectively improve the most stuck at the sealing of existing long shaft submerged pump and the problem of maintenance difficult, move in the sealing system of this kind of long shaft submerged pump above base plate, replaced by packing_seal and the technical scheme of secret envelope, both sealing function had been served, also the impurity particle avoiding medium to open enters at sealing, make sealing stuck, bearing is dust-proof simultaneously, increase the service life, move in sealing system and be easy to dismounting maintenance, lower the cost of user.

In figure 1, axle；2, base plate；3, structure is sealed；4, filler casing；5, graphite packing filling；6, gland；7, bearing housing；8, location lining；9, pump cover；10, axle sleeve；11, bar-shaped trough；12, motor.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further.
As Fig. 1 combines Fig. 2, Fig. 3, shown in Fig. 4, a kind of sealing device of long shaft submerged pump, including axle 1 and base plate 2, axle 1 top connects motor 12, described base plate 2 is arranged over sealing structure 3, described sealing structure 3 includes filler casing 4 and graphite packing filling 5, described filler casing 4 is fixedly connected on bearing housing 7 by location screw, described bearing housing 7 is fixedly connected on base plate 2, described axle 1 lower end is provided with location lining 8, described graphite packing filling 5 seals with axle 1 in being placed in filler casing 4, described graphite packing filling 5 is arranged over gland 6, gland 6 is fixed on filler casing 4 by alignment pin.
Pump is sealed by the form that this sealing structure 3 replaces original mechanical seal to be placed in pump cover, it is to avoid makes because there being impurity to enter in medium and seals stuck, damages pump, seals to move in structure 3 simultaneously and is easy to dismounting maintenance, easy to use.
Described location lining 8 is secured within pump cover 9, it is provided with axle sleeve 10 between location lining 8 and axle 1, described axle sleeve 10 is fixed on axle 1, it is provided with tolerance between location lining 8 and axle sleeve 10, this tolerance is 56, axle sleeve 10 moves with axle 1 relative localization lining 8, keep axiality, described location lining 8 inner surface is provided with bar-shaped trough 11, described bar-shaped trough 11 trench bottom is that globoidal structure is arranged, bar-shaped trough 11 is easy to flowing down of the i.e. medium of coolant, the heat radiation of heat is produced when axle 1 works, cooling rubbing surface, good heat dissipation effect, will location lining 8 be set at former sealing structure 3, move in former sealing structure above base plate 2, avoid sealing structure 3 and be placed in liquid level situation once, place granule foreign impact in medium to seal, extend pump service life.
This utility model effectively improves the most stuck at the sealing of existing long shaft submerged pump and the problem of maintenance difficult, move to above base plate in the sealing structure of this kind of long shaft submerged pump, replaced by packing_seal and the technical scheme of secret envelope, both having served sealing function, the impurity particle also avoiding medium to open enters at sealing, makes sealing stuck, bearing is dust-proof simultaneously, increase the service life, seal to move in structure 3 and be easy to dismounting maintenance, lower the cost of user.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention; but invention thought of the present utility model is not limited to that utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
