Description
Technical field
The present invention relates to a kind of stuffing-box, belong to the sealing technical field with stuffing-box.
Background technology
The existing pump packing using sizing specification, is filled in the stuffing-box of pump more.Although this sealing means is relatively simple, a certain degree of effect can be played, but between this type of packing and pump shaft, still there is a certain degree of friction, even if the packing that coefficient of friction is the least, it is also surprising with the caloric value of axle contact position, therefore generally requires cooperation cooling system cooperation.Life-time service is also quite serious to bearing wear simultaneously, and life-time service countershaft can manufacture into permanent injury.
Muddy packing------is also referred to as: " pouring-in soft packing " is equipped with special oils and fats and lubrication by a new generation's high-performance fiber, refined senior " packing " soft packing, arbitrary dimension, arbitrary shape, easily install, just can direct injection by special High Pressure Gun, it is not necessary to as traditional packing, need precut, the packing box seal of any size can be suitable for.
Installing soft packing and need the prestressing force certain to filler, i.e. the filler in stuffing-box is applied a power, the direction of power is directed to pump shaft, as shown in Figure 1, is the structural representation of an immersible pump, is stuffing-box in figure centre circle, and the lower section of stuffing-box is impeller 1.Owing to immersible pump is typically all underwater operation, therefore add after filler needs to take out pump from water and add, more bother.And when filler surplus is too low, the pump housing can be affected and normally work, the phenomenons such as pump housing vibrations impeller shake occur.
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, the immersible pump stuffing-box of display filler surplus.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of immersible pump filler surplus display stuffing-box includes 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, and described column packing cavity one end extends to described first filler seat and is communicated to inside described first filler seat, and the described column packing cavity other end extends the pump housing；Described column packing cavity is provided with hydraulic outside the pump housing, and described hydraulic includes: the first plunger, the second plunger and working media；Described filler residue display device includes: metal contact, metal column, light emitting diode, protection load and safety switch; described hard contact is arranged on the contact surface 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 source series connection.
Described column packing cavity quantity is four, and is respectively perpendicular and is located on the sidewall that described second filler seat is different.
Described first plunger is arranged on described hydraulic near described pump housing outside, described second plunger is arranged on described hydraulic near described stuffing-box end, and contact with the filler being filled in described stuffing-box, described working media is mineral oil, and is filled between described first plunger and described second plunger.
When using this stuffing-box, and need to fill up filler in described column packing cavity in described first filler seat, described filler is muddy packing.
Described metal column sets the scalable metal column of spring in being.
The present invention uses technique scheme to provide the benefit that: the pressure of water is passed on the filler in column packing cavity by hydraulic drive, 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 uses hydraulic pressure as applied external force, it is not necessary at the parts separately setting pressuring action.
And display lamp can be extinguished when filler surplus is too low to remind, it is to avoid the problem that the water pump that remains in operation when filler surplus is too low brings.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the immersible pump mentioned in background technology.
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.
Detailed description of the invention
Embodiment
The present embodiment filler surplus display stuffing-box be used in immersible pump as shown in Figure 1, Fig. 2 be in Fig. 1 in circle part partial enlarged drawing, this enlarged drawing show stuffing-box 2 general structure, its A-A sectional view is as shown in Figure 3.In use, this stuffing-box can automatically load filler by external water pressure, extends the use cycle, alleviates artificial burden.
A kind of immersible pump filler surplus display stuffing-box of the present embodiment, this stuffing-box includes first filler seat the 5, second filler seat 3, column packing cavity 6 and filler residue display device, first filler seat 5 is installed on outside the axle sleeve 4 of pump shaft 7, 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 section 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, and column packing cavity 6 one end extends to the first filler seat 5 and is communicated to the first filler seat 3 inside, and column packing cavity 6 other end extends the pump housing；Column packing cavity 6 is provided with hydraulic (not shown) outside the pump housing, and described hydraulic includes: the first plunger, the second plunger 8 and working media；Filler residue display device includes: metal contact, metal column 9, light emitting diode, protection load and safety switch; hard contact is arranged on the contact surface of the second plunger 8 and filler; metal column 9 is arranged on axle sleeve 4, and hard contact is in parallel with light emitting diode by copper paint envelope curve with metal column；Light emitting diode is with protecting load, safety switch and DC source series connection.
