Description
Technical field
The utility model relates to a kind of stuffing box, belongs to the shaft sealing technical field with stuffing box.
Background technique
The existing pump packing adopting sizing specification, is filled in the stuffing box of pump more.Although this sealing means is comparatively easy, effect to a certain extent can be played, but the friction still also existed between this type of packing and pump shaft 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.Long-Time Service is also quite serious to bearing wear simultaneously, and Long-Time Service can cause permanent injury to bearing.
Muddy packing------also claims: " pouring-in soft packing " is equipped with special grease and lubrication by high-performance fiber of new generation, refining senior " packing "---soft packing, arbitrary dimension, arbitrary shape, very easily install, just can directly be injected by special High Pressure Gun, traditional packing need not be resembled, need precut, the packing box seal of any size can be suitable for.
Installing soft packing needs to the certain prestressing force of filler, namely will apply a power to the filler in stuffing box, and pump shaft is pointed in the direction of power, and as shown in Figure 1, being the structural representation of a submersible pump, is stuffing box in figure centre circle, and the below of stuffing box is impeller 1.Because submersible pump is all generally underwater operation, therefore adding filler needs pump to be taken out from water rear interpolation, comparatively bothers.And when filler surplus is too low, the pump housing can be affected and normally work, occur the phenomenons such as pump housing vibrations impeller shake.
Model utility content
The technical problems to be solved in the utility model is, not enough for prior art, propose a kind of can automated packing, display filler surplus submersible pump stuffing box.
The utility model is the technological scheme solving the problems of the technologies described above proposition: a kind of submersible pump filler surplus display stuffing box comprises the first filler seat, the second filler seat, column packing cavity and filler residue display device, described first filler seat is installed on outside the axle sleeve of pump shaft, described second filler seat is installed on outside described first filler seat, and described first filler seat and described second filler seat cross section are square; Described column packing cavity is arranged on the sidewall of described second filler seat along the radial direction of described pump shaft, described column packing cavity one end extends to described first filler seat and is communicated to described first filler seat inside, and the described column packing cavity the other end extends the pump housing; Described column packing cavity has hydraulic transmission near pump housing arranged outside, and described hydraulic transmission comprises: the first plunger, the second plunger and working medium; 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 second plunger 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 protecting load, safety switch and DC electrical source series connection.
Described column packing cavity quantity is four, and is vertically located in respectively on the different sidewall of described second filler seat.
Described first plunger is arranged on described hydraulic transmission near described pump housing outside, described second plunger is arranged on described hydraulic transmission near described stuffing box end, and contact with the filler be filled in described stuffing box, described working medium is mineral oil, and is filled between described first plunger and described second plunger.
When using this stuffing box, need fill up filler in described first filler seat He in described column packing cavity, described filler is muddy packing.
Described metal column establishes the scalable metal column of spring in being.
The beneficial effect of the utility model employing technique scheme is: the pressure of water passes on the filler in column packing cavity by hydraulic transmission, when the filler in the first filler seat consumes, under hydraulic pressure effect, the filler in column packing cavity is just pushed in the first filler seat by the second plunger; And this case adopts hydraulic pressure as applied external force, does not need at the parts separately establishing pressuring action.
And tutorial light can be extinguished when filler surplus is too low to remind, the problem that water pump of avoiding remaining in operation when filler surplus is too low brings.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
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
