Abstract
The invention provides an anti-leakage device used for the dynamic seal position of a water pump, and belongs to dynamic seal refitting of a submerged pump. The anti-leakage device comprises a pump shaft and a filler body wrapping the pump shaft. An inner hole is machined between the filler body and the pump shaft. A framework oil seal stuffing box is embedded in the inner hole. A framework oil seal is arranged in the framework oil seal stuffing box. Adjustment rings used for adjusting the tightness degree of the framework oil seal are arranged at the upper end and the lower end of the framework oil seal. A filler gland connected with the filler body is arranged on the upper portion of the inner hole of the filler body. The anti-leakage device has the beneficial effects that the leakage problem is solved, and therefore the maintenance frequency of the pump is reduced; and meanwhile, expenses of spare parts such as pump shaft pump sleeves and filler bodies are saved, and the workloads of maintainers are reduced.
Description
Technical field
The invention belongs to the motive sealing transformation of Under Water Pumps.
Background technique
The form that existing Under Water Pumps is sealed into butter rope filling filling body seals, this kind of seal form is subject to the restriction of this pump structure, when there is seal leakage in running, if want to change packing rope, will be very difficult, due to packing gland and gap, filling body upper-end surface too small cause operate limited, namely clear up old packing rope completely and have certain difficulty, even can not clear up thoroughly, and the packing rope newly added is not easy to add reality, the leakage problem causing this pump to be arranged on pump on pond, ground cannot be solved thoroughly.Reason is mainly because packing rope causes wick aging, hardening after long time running, and cause pump shaft surface and filling body inwall to form cut, can not add tight when substantially changing butter rope, just Seepage is had after pump testing, general use will start water dumping after one week, if solve this phenomenon thoroughly to solve by changing stand by pump, solution replaces with axle sleeve and filling body after disintegrating by water pump.
Summary of the invention
The object of the invention is, a kind of leakage preventer of motive sealing place for water pump is provided
In order to achieve the above object, the technical solution used in the present invention is:
A kind of leakage preventer of motive sealing place for water pump, comprise the filling body of pump shaft and parcel pump shaft, it is characterized in that: between described filling body and pump shaft, process an endoporus, outside framework oil seal stuffing box is inlayed in endoporus, outside framework oil seal is provided with in described outside framework oil seal stuffing box, be provided with the adjustment ring for adjusting outside framework oil seal tightness at the two ends up and down of outside framework oil seal, described filling body endoporus top is provided with the packing gland be connected with filling body.
Bottom above-described reinforced seal stuffing box and processed after filling body endoporus between be provided with rubber pad.
The invention has the beneficial effects as follows: solve leakage problem, thus decrease the maintenance frequency of pump, save the spare part expenses such as pump shaft pump block and filling body simultaneously, and decrease the workload of maintainer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1. pump shaft; 2. packing gland; 3. filling body; 4. outside framework oil seal stuffing box; 5. adjustment ring; 6. outside framework oil seal; 7. rubber pad.
Embodiment
From accompanying drawing 1, the present invention includes the filling body 3 of pump shaft 1 and parcel pump shaft 1, an endoporus is processed between described filling body 3 and pump shaft 1, outside framework oil seal stuffing box 4 is inlayed in endoporus, outside framework oil seal 6 is provided with in described outside framework oil seal stuffing box 4, be provided with the adjustment ring 5 for adjusting outside framework oil seal tightness at the two ends up and down of outside framework oil seal 6, described filling body 3 endoporus top is provided with the packing gland 2 be connected with filling body 3.After adjustment ring 5 and outside framework oil seal 6 are assembled, its height should, a little more than the exterior edge face of filling body 3, like this when being assembled with filling body 3 by packing gland 2, can make adjustment ring 5 and outside framework oil seal 6 be subject to downward pressure, increases the sealing intensity with pump shaft 1.
The present invention utilizes existing water pump filling body to process, endoporus increases diameter of bore by lathe cutting, then a reinforced seal stuffing box 4 is processed with polytetrafluoroethylmaterial material, be set in foregoing processed after filling body 3 on, reinforced seal stuffing box 4 with processed after filling body 3 inlay time, install the rubber pad 7 that a 2mm is thick between additional, to play seal action between the two.
Only the filling body be worn need be pulled down repairing in pump process, after carrying out car endoporus, assemble with the reinforced seal stuffing box 4 processed in advance, thus decrease the maintenance frequency of pump, save the spare part expenses such as pump shaft pump block and filling body simultaneously, and decrease the workload of maintainer.
Claims (2)
1. the leakage preventer for motive sealing place of water pump, comprise the filling body of pump shaft and parcel pump shaft, it is characterized in that: between described filling body and pump shaft, process an endoporus, outside framework oil seal stuffing box is inlayed in endoporus, outside framework oil seal is provided with in described outside framework oil seal stuffing box, be provided with the adjustment ring for adjusting outside framework oil seal tightness at the two ends up and down of outside framework oil seal, described filling body endoporus top is provided with the packing gland be connected with filling body.
