Abstract
The utility model discloses an anti-leakage structure of a long-axis submerged pump, which comprises a shaft (1), a shaft sleeve (2), a water outlet elbow (3), a packing seal (4) and a sealing gland (5). The anti-leakage structure of a long-axis submerged pump is characterized in that a throttling ring (6) is sleeved at the lower end of the shaft sleeve (2), an opening is arranged in an annular groove closed by the water outlet elbow (3) and the shaft sleeve (2), and a reflux pipe (7) leading to a pump sump is disposed at the opening. By means of matching the throttling ring with the reflux pipe, the anti-leakage structure of a long-axis submerged pump can reduce abrasion of packing and the packing shaft sleeve to the utmost extent while realizing zero leakage, and leads sealing property to be more reliable, thereby reducing maintenance cost and prolonging service life.
Description
Technical field
The utility model relates to a kind of pump structure, especially relates to a kind of long shaft submerged pump leakage-proof structure.
Background technique
Long shaft submerged pump is mainly used in industrial and mining enterprise such as water utility, sewage treatment works, power plant, Iron And Steel Plant, mine, and in municipal plumbing, field irrigation, the engineering such as control flood and drain flooded fields.At present, the sealing configuration of long shaft submerged pump at the pump shaft place mainly adopts packing seal to add the gland form and realizes that medium is when upwards flowing, because medium is to the pressure of packing seal place, more or less can leak, cause strengthening maintenance cost, influence the working life of pump from the sealing configuration of pump shaft.
Summary of the invention
The purpose of this utility model provides a kind of long shaft submerged pump leakage-proof structure that can reduce packing seal place pressure.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises axle and axle sleeve, Discharging bent-tube, packing seal and sealing gland, the lower end that it is characterized in that described axle sleeve is set with restrictor ring, be provided with opening in the circular groove of Discharging bent-tube and axle sleeve sealing, opening is provided with the reflow pipe that leads to the pump pond.
The structure that the utility model adopts is used restrictor ring and reflow pipe, can reduce the wearing and tearing of filler and packing sleeve to greatest extent when realizing zero leakage, makes sealability more reliable, thereby reduces maintenance cost, increases the service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Among the figure 1, axle 2, axle sleeve 3, Discharging bent-tube 4, packing seal 5, sealing gland 6, restrictor ring 7, reflow pipe
Embodiment
By accompanying drawing as can be known, this long shaft submerged pump leakage-proof structure comprises axle 1 and axle sleeve 2, Discharging bent-tube 3, packing seal 4 and sealing gland 5, the lower end that it is characterized in that described axle sleeve 2 is set with restrictor ring 6, be provided with opening in the circular groove of Discharging bent-tube 3 and axle sleeve 2 sealings, opening is provided with the reflow pipe 7 that leads to the pump pond.Restrictor ring in the utility model can adopt the 0Cr18Ni9 stainless steel to make, and can be used for increasing the resistance of leakage flow, and excellent sealing performance can be provided, and is wear-resistant, can well protect packing seal, reduces the pressure of packing seal place.The part medium back flow that reflow pipe can leak between centers Da Chi to the pump.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation or changes on the basis of the above description.Here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present utility model draws and still are among the protection domain of the present utility model.
