Abstract
The invention relates to a stuffing box, in particular to a submerged pump stuffing box capable of displaying the amount of residual stuffing and belongs to the technical field of shaft seals with stuffing boxes. The submerged pump stuffing box capable of displaying the amount of residual stuffing comprises a first stuffing base, a second stuffing base, a columnar stuffing cavity and a device for displaying the amount of residual stuffing. The first stuffing base is installed outside a shaft sleeve of a pump shaft. The second stuffing base is installed outside the first stuffing base. The section of the first stuffing box and the section of the second stuffing box are both squares. The columnar stuffing cavity is arranged on the side wall of the second stuffing base in the radial direction of the pump shaft. One end of the columnar stuffing cavity extends to the first stuffing base and is communicated with the interior of the first stuffing base. The other end of the columnar stuffing cavity is sealed. A bolt is arranged at the sealed end of the columnar stuffing cavity. The bolt is sleeved with a spring. The end, far away from the bolt, of the spring is connected with a gland plate. The submerged pump stuffing box is long in service life and convenient to use.
Description
Technical field
The present invention relates to a kind of stuffing box, belong to the shaft sealing technical field with stuffing box.
Background technique
Existing pump adopts the packing of sizing specification more, is filled in the stuffing box of pump.Although this sealing means is comparatively easy, can play effect to a certain extent, yet between this type of packing and pump shaft, still exist friction to a certain degree, even if the packing that friction factor is very little, it is also surprising with the heating value of the synapsis that is coupling, and therefore often needs to coordinate cooling system co-operation.Use is for a long time also quite serious to bearing wear simultaneously, and long-term use meeting causes permanent injury to bearing.
Muddy packing------also claims: " pouring-in soft packing " is equipped with special grease and lubricated by high-performance fiber of new generation, refining senior " packing "---the soft packing forming, arbitrary dimension, arbitrary shape, very easily install, by special-purpose High Pressure Gun, just can directly inject, needn't resemble traditional packing, need to precut, can be suitable for the packing box seal of any size.
Soft packing is installed and need to gives the certain prestressing force of filler, will apply to the filler in stuffing box a power, the direction of power is to point to pump shaft, as shown in Figure 1, is the structural representation of a submersible pump, in figure centre circle, is stuffing box, and the below of stuffing box is impeller 1.Because submersible pump is all generally underwater operation, therefore add filler and pump need to be taken out from water to rear interpolation, comparatively trouble.And when filler surplus is too low, can affects the pump housing and normally work, occur the phenomenons such as pump housing vibrations impeller shake.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, propose a kind of can automated packing, show the submersible pump stuffing box of filler surplus.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: submersible pump shows stuffing box by filler surplus, this stuffing box comprises the first filler seat, the second filler seat, column packing cavity and filler residue display device, described the first filler seat is installed on outside the axle sleeve of pump shaft, described the second filler seat is installed on outside described the first filler seat, and described the first filler seat and described the second filler seat cross section are square; Described column packing cavity is arranged on the sidewall of described the second filler seat along the radial direction of described pump shaft, described column packing cavity one end extends to described the first filler seat and is communicated to described the first filler seat inner, described column packing cavity the other end sealing, described closed end is provided with bolt, on described bolt, be equipped with spring, described spring is connected with cover clamp away from one end of bolt; Described filler residue display device comprises: metal contact, metal column, light emitting diode, protection load and safety switch, described hard contact is arranged on the surface of contact of described cover clamp and filler, described metal column is arranged on described axle sleeve, and described hard contact is in parallel with light emitting diode by copper paint envelope curve with metal column; Described light emitting diode is with protection load, safety switch and DC electrical source series connection.
When using this stuffing box, need in described the first filler seat He in described column packing cavity, fill up filler, described filler is muddy packing.
Described metal column is established the scalable metal column of spring in being.
The present invention adopts the beneficial effect of technique scheme to be: by pressure spring being applied on cover clamp, promote filler, when the filler in the first filler seat consumes, cover clamp is just pushed the filler in column packing cavity in the first filler seat; And this case adopts hydraulic pressure as applied external force, need to be at the parts of separately establishing pressuring action.
And can when filler surplus is too low, extinguish tutorial light to remind, the problem that the water pump of avoiding remaining in operation brings when filler surplus is too low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of the submersible pump mentioned in background technique.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the A-A sectional view of stuffing box 2 in Fig. 2.
Embodiment
Embodiment
The filler surplus of the present embodiment shows that stuffing box is used in submersible pump as shown in Figure 1, and Fig. 2 is the partial enlarged drawing of part in circle in Fig. 1, stuffing box 2 general structures that this enlarged view is shown, and its A-A sectional view is as shown in Figure 3.In use, this stuffing box can be loaded filler automatically by external water pressure, extends life cycle, alleviates artificial burden.
The submersible pump of the present embodiment shows stuffing box by filler surplus, as shown in Figure 3, this stuffing box comprises the first filler seat 5, the second filler seat 3, column packing cavity 6 and filler residue display device, the first filler seat 5 is installed on outside the axle sleeve 4 of pump shaft 7, the second filler seat 3 is installed on outside the first filler seat 5, and the first filler seat 5 and the second filler seat 3 cross sections are square; Column packing cavity 6 is arranged on the sidewall of the second filler seat 3 along the radial direction of pump shaft 7, column packing cavity 6 one end extend to the first filler seat 5 and are communicated to the first filler seat 3 inside, 6 the other end sealings of column packing cavity, closed end is provided with bolt, on bolt, be equipped with spring, spring is connected with cover clamp 8 away from one end of bolt; Filler residue display device comprises: metal contact, metal column 9, light emitting diode, protection load and safety switch, hard contact is arranged on the surface of contact of cover clamp 8 and filler, metal column 9 is arranged on axle sleeve, and hard contact is in parallel with light emitting diode by copper paint envelope curve with metal column 9; Light emitting diode is with protection load, safety switch and DC electrical source series connection.
When using this stuffing box, need be the first filler seat 3 in column packing cavity in 6 fill up filler, filler is muddy packing.
