Abstract
The utility model provides a glue metering pump with high sealing performance. The glue metering pump comprises a pump body (3) and a rotating shaft (4), wherein the rotating shaft (4) is arranged on the pump body (3) in a rotating manner; a seal device which is used for preventing glue in the pump body from leaking outside along the rotating shaft (4) is arranged between the pump body and the rotating shaft. The glue metering pump is characterized in that the seal device is a mechanical seal (2) which is sleeved on the rotating shaft (4); one end of the mechanical seal (2) props against the pump body (3), and the other end of the mechanical seal (2) is connected with a gland (1); the gland (1) is fixedly connected with the pump body (3).
Description
Technical field
The utility model relates to spinning pump technical field, specifically refers to a kind of glue metering pump.
Background technique
Metering pump is a kind ofly can meet various strict technological process needs, flow can be within the scope of 0-100% step-less adjustment, be used for carrying a kind of special displacement pump of liquid (particularly corrosive liquids).Metering pump also claims metering pump or dosing pump.Metering pump belongs to reciprocating volumetric pump, for accurate measurement.Along with the development of modernization industry towards automation mechanized operation, this situation of far distance automatic controlling, the matching performance of metering pump is strong, advantage is particularly evident widely to adapt to medium, so find broad application industrial.Spinning pump is widely used in chemical fiber plant as a kind of of metering pump.Spinning pump of the prior art is to adopt gear structure mostly, it comprises a driving gear and a driven gear, two gears intermesh, while rotating by gear, gap between tooth and tooth is come quantitative medium (chemical fibre used of spinning, glue, finish etc.) to be transported to opposite side from a side of gear.Described driving gear is provided with the driving shaft that driven gear rotates, and driving shaft is driven by power sources such as motors.In prior art, there is a kind of glue metering pump for spinning, between its rotating shaft and the pump housing, be all generally that the sealed packing adopting seals, although this sealing configuration cost is low, early stage good sealing effect, but the prolongation along with service time, packing can grind fewer and fewer, thereby leak, as shown in Figure 1, glue metering pump of the prior art, comprise gland 01, sealed packing 02, the pump housing 03 and rotating shaft 04, sealed packing 02 is filled between rotating shaft 04 and the pump housing 03, and is compressed by gland 01.In the course of the work, along with extend service time, the place that sealed packing 02 contacts with rotating shaft 04 can be worn metering pump, thereby sealability declines.Therefore in prior art there is the shortcoming that sealability is not high in the glue metering pump for spining technology field.
Model utility content
The technical problems to be solved in the utility model is that the glue metering pump that a kind of sealability is higher is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: a kind of glue metering pump, and it comprises the pump housing and rotating shaft; Rotating shaft is rotatably installed on the pump housing, and is provided with between the two for preventing glue in the pump housing seal arrangement along rotating shaft to external leakage; Described seal arrangement is mechanical seal, and described mechanical seal is socketed in rotating shaft, and one end and the pump housing of mechanical seal offset, and the other end of mechanical seal is connected with gland, and gland is fixedly connected with the pump housing.
Adopt after above structure, the utlity model has following advantage: adopt after mechanical seal, originally rotating shaft is to rub with whole packing, only have now the special-purpose friction member in mechanical seal to rub, rubbing surface reduces, and stability is higher, and sealability is also just better.
As preferably, described mechanical seal is the modular mechanical seal with kinetic friction ring and static friction ring.Kinetic friction ring coordinates with static friction ring, and in modular mechanical seal, both are ceramic structure, and friction factor is little, is more not easy to leak.
Accompanying drawing explanation
Fig. 1 is the structural representation of glue metering pump in prior art.
Fig. 2 is the structural representation of glue metering in the utility model.
As shown in the figure: in prior art: 01, gland, 02, sealed packing, 03, the pump housing, 04, rotating shaft.
1, gland, 2, mechanical seal, 3, the pump housing, 4, rotating shaft, 5, kinetic friction ring, 6, static friction ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
By reference to the accompanying drawings 2, a kind of glue metering pump, it comprises the pump housing 3 and rotating shaft 4; Rotating shaft 4 is rotatably installed on the pump housing 3, and is provided with between the two for preventing glue in the pump housing seal arrangement along rotating shaft 4 to external leakage; Described seal arrangement is mechanical seal 2, and described mechanical seal 2 is socketed in rotating shaft 4, and one end of mechanical seal 2 and the pump housing 3 offset, and the other end of mechanical seal 2 is connected with gland 1, and gland 1 is fixedly connected with the pump housing 3.Described mechanical seal 2 is the modular mechanical seal with kinetic friction ring 5 and static friction ring 6.
The utility model in the specific implementation, described glue metering pump also comprises other conventional components identical with glue metering pump structure of the prior art, as driving gear, driven gear etc., because the related inventive point of these parts and the application does not have substantial annexation, so describe in detail no longer one by one herein, described mechanical seal 2 has ripe commercially available.
Above the utility model and mode of execution thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of mode of execution of the present utility model, and actual structure is not limited to this.If generally speaking those of ordinary skill in the art is enlightened by it, in the situation that not departing from the utility model creation aim, without the creationary mode of structure similar to this technological scheme and the embodiment of designing, all should belong to protection domain of the present utility model.
Claims (2)
1. a glue metering pump, it comprises the pump housing (3) and rotating shaft (4); It is upper that rotating shaft (4) is rotatably installed in the pump housing (3), and be provided with between the two for preventing glue in the pump housing seal arrangement along rotating shaft (4) to external leakage; It is characterized in that: described seal arrangement is mechanical seal (2), described mechanical seal (2) is socketed in rotating shaft (4), one end of mechanical seal (2) and the pump housing (3) offset, the other end of mechanical seal (2) is connected with gland (1), and gland (1) is fixedly connected with the pump housing (3).
2. glue metering pump according to claim 1, is characterized in that: described mechanical seal (2) is the modular mechanical seal with kinetic friction ring (5) and static friction ring (6).
