Abstract
The utility model discloses a stuffing seal structure with an air exhaust chamber. The stuffing seal structure comprises an upper protective pipe (1), an upper guide bearing (2), a stuffing box (3), a stuffing shaft sleeve (4) and a lubrication water cavity (9), wherein a water inlet chamber (7) is formed by the upper guide bearing (2), the stuffing box (3) and the stuffing shaft sleeve (4); the air exhaust chamber (6) is arranged in the water inlet chamber (7) of the stuffing box (3); the upper protective pipe (1) is provided with an air exhaust hole (8) used for communicating the lubrication water cavity (9) and the air exhaust chamber (6); and the stuffing box (3) is provided with an automatic air exhaust valve (5) which is connected with the air exhaust chamber (6). With the adoption of the stuffing seal structure provided by the utility model, the air in the lubrication water cavity can be exhausted completely, and the lubrication of the upper guide bearing is excellent; and the stuffing seal structure is provided with the air exhaust chamber, compact in structure, convenient to use and widely used on a vertical diagonal flow pump, and has strong practical and popularization values.
Description
Technical field
The utility model relates to a kind of packing seal structure, particularly relates to a kind of packing seal structure with exhaust cavity that is applied to the pump series products such as vertical diagonal flow pump.
Background technique
Packing seal is the shaft seal mode of vertical diagonal flow pump, and external press water upwards forms water seal water after entering water-inlet cavity from the stuffing box lower end, and the top guide bearing groove of flowing through downwards carries out water lubrication to guide bearing, and pillar consists of lubricated water chamber.But because the air in lubricated water chamber can't be emptying, cause the top guide bearing insufficient lubrication, can cause the overheated phenomenon that burns out of guide bearing.
The model utility content
It is emptying that technical problem to be solved in the utility model is to provide a kind of interior air of lubricated water chamber that can make, and makes top guide bearing lubricate the good packing seal structure with exhaust cavity.
In order to solve the problems of the technologies described above, the packing seal structure with exhaust cavity that the utility model provides, comprise pillar, top guide bearing, stuffing box, packing sleeve and lubricated water chamber, top guide bearing and stuffing box, packing sleeve form water-inlet cavity, the water-inlet cavity of described stuffing box divides and is separated with exhaust cavity, described upper pillar increases the exhaust port that is communicated with described lubricated water chamber and exhaust cavity, is provided with the automatic control pressure vent that is connected with described exhaust cavity on described stuffing box.
Adopt the packing seal structure with exhaust cavity of technique scheme, due to adopted upper pillar with exhaust port, with stuffing box and the automatic control pressure vent of exhaust cavity, can be effectively the air that lubricates in water cavity be discharged automatically, prevent that effectively guide bearing from burning phenomenon to death because insufficient lubrication causes.
In sum, the utility model is that a kind of interior air of lubricated water chamber that can make is emptying, makes top guide bearing lubricate the good packing seal structure with exhaust cavity, compact structure, easy to use, extensively be used on vertical diagonal flow pump, have very strong practical and popularizing value.
Description of drawings
Fig. 1 is the packing seal structure figure of the utility model band exhaust cavity.
Fig. 2 is packing seal structure figure before improving.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, comprise pillar 1, top guide bearing 2, stuffing box 3, packing sleeve 4 and lubricated water chamber 9, top guide bearing 2 forms water-inlet cavity 7 with stuffing box 3, packing sleeve 4, packing seal is the shaft seal mode of vertical diagonal flow pump, external press water upwards forms water seal water, the top guide bearing groove of flowing through downwards after entering water-inlet cavity 7 from the stuffing box lower end, guide bearing is carried out water lubrication, and pillar consists of lubricated water chamber 9.But because the air in lubricated water chamber 9 can't be emptying, cause the top guide bearing insufficient lubrication, can cause the overheated phenomenon that burns out of guide bearing.
Referring to Fig. 1, top guide bearing 2, packing sleeve 4 are consistent with the part of original structure, and the water-inlet cavity of stuffing box 3 was separated with exhaust cavity 6 in 7 minutes, and upper pillar 1 increases exhaust port 8, exhaust port 8 is communicated with lubricated water chamber 9 and exhaust cavity 6, and increasing on stuffing box 3 has the automatic control pressure vent 5 that is connected with exhaust cavity 6.
Referring to Fig. 1 and Fig. 2, due to adopted upper pillar 1 with exhaust port 8, with stuffing box 3 and the automatic control pressure vent 5 of exhaust cavity, can effectively the air that lubricate in water chamber 9 be discharged automatically, prevent that effectively guide bearing from burning phenomenon to death because insufficient lubrication causes.The utility model compact structure, easy to use, extensively be used on vertical diagonal flow pump, have very strong practical and popularizing value.
Personnel in the art should be realized that, above-described embodiment is not with this novel restriction of opposing, as long as in this novel connotation scope, any above-described embodiment technique variation, flexible program are not all exceeded protection domain of the present utility model.
Claims (1)
1. packing seal structure with exhaust cavity, comprise pillar (1), top guide bearing (2), stuffing box (3), packing sleeve (4) and lubricated water chamber (9), top guide bearing (2) and stuffing box (3), packing sleeve (4) forms water-inlet cavity (7), it is characterized in that: the water-inlet cavity (7) of described stuffing box (3) minute is separated with exhaust cavity (6), described upper pillar (1) increases the exhaust port (8) that is communicated with described lubricated water chamber (9) and exhaust cavity (6), be provided with the automatic control pressure vent (5) that is connected with described exhaust cavity (6) on described stuffing box (3).
