Abstract
The utility model discloses a sealing device for a high-pressure vertical long-axis pump, comprising a filling box (3), a filling bushing (4), a filling shaft sleeve (5), a filling pressure cover (8),a filler (9) and a transmission shaft (10). The filling bushing (4) is fixed on the filling box (3); the filling shaft sleeve (5) is fixed on the transmission shaft (10); the filling pressure cover (8) is connected with the filling box (3) through a stud (6); the filler (9) is packed between the filling bushing (4) and the filling pressure cover (8); and a decompression water pipe (2) is connected on the filling box (3) and is provided with a pressure regulating valve (1). The sealing device for a high-pressure vertical long-axis pump has simple structure, favorable sealing performance and convenient use, can be widely applied to a high-pressure vertical long-axis pump, particularly a long-axis fire pump and has great practical and promotional value.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly relates to a kind of high pressure vertical major axis Sealing used for pump.
Background technique
Vertical pump is widely used, and when fed sheet of a media pressure was higher, the axle envelope problem of pump was most important especially.Most of high pressure vertical pumps on its structure more adopts spiral seal, but common spiral seal must be passed through accurate calculating, and must adopt high viscosity liquid as sealing fluid, just can reach the sealing effect of expection, and therefore, use is subjected to certain narrow limitation; When axle and axis hole occur eccentricly, and offset can occur the narrow phenomenon of gap one hem width between screw thread and the hole on one side, thereby cause the flow resistance difference when big, leaks and can produce the working life that can reduce sealing simultaneously in broad gap one side.
The model utility content
Technical problem to be solved in the utility model provides a kind of simple in structure, safe and reliable high pressure vertical major axis Sealing used for pump.
In order to solve the problems of the technologies described above, the high pressure vertical major axis Sealing used for pump that the utility model provides, comprise stuffing box, packing bushing, packing sleeve, Gland, filler and transmission shaft, described packing bushing is fixed on the described stuffing box, described packing sleeve is fixed on the described transmission shaft, described Gland links to each other with described stuffing box by double-screw bolt, described filler is contained between described packing bushing and the described Gland, the pressure release water pipe is connected on the described stuffing box, on described pressure release water pipe pressure regulator valve is installed.
Described packing sleeve external diameter car has the double end square threaded form corresponding with described transmission shaft sense of rotation.
Adopt the high pressure vertical major axis Sealing used for pump of technique scheme, have good sealing function.Compare with original technology and to have following advantage:
During pump operation, fluid pressure after the process spiral seal and leakage rate all obtain reduction to a certain degree, by regulating pressure regulator valve, guarantee that packing seal place liquid becomes to drip shape and spills, rather than reduce the leakage rate of liquid by the nut of tightening Gland, thereby avoided pressing too tightly, and the power that water pump is consumed is excessive and the phenomenon of filler place appearance heating, has improved the security of operation of pump group and the working life of part because of filler.
In sum, the utility model is a kind of simple in structure, safe and reliable high pressure vertical major axis Sealing used for pump.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, packing bushing 4 is fixed on the stuffing box 3 by positioning screwn 11, packing sleeve 5 is fixed on the transmission shaft 10 by key 12 and sleeve nut 7, Gland 8 links to each other with stuffing box 3 by double-screw bolt 6, filler 9 is contained between packing bushing 4 and the Gland 8, pressure release water pipe 2 is connected on the stuffing box 3 by pipe thread, and pressure regulator valve 1 is installed on pressure release water pipe 2, and packing sleeve 4 external diameter cars have the double end square threaded form corresponding with transmission shaft 10 sense of rotation.
Referring to Fig. 1, earlier packing bushing 4 is fixed in the stuffing box 3 by positioning screwn 11, again packing sleeve 5 is fixed on the transmission shaft 10 by key 12 and sleeve nut 7, filler 9 is contained in the stuffing box 3, be between packing bushing 4 and the Gland 8, Gland 8 links to each other with stuffing box 3 by double-screw bolt 6, pressure release water pipe 2 is fixed on the stuffing box 3 by pipe thread, and pressure regulator valve 1 is installed on the pressure release water pipe 2.During pump operation, regulate pressure regulator valve 1, thereby guarantee that liquid becomes to drip shape and spills according to the leakage rate of packing seal place.
This vertical pump is simple with sealing device structure, has excellent sealing performance, and working service is convenient, can extensively be used on the high pressure vertical major axis pump, has good economic benefits.
Personnel in the present technique field should be realized that, the foregoing description is not with this novel qualification of opposing, as long as in this novel connotation scope, any the foregoing description technique variation, flexible program are not all exceeded protection domain of the present utility model.
Claims (2)
