Description
Technical field
The present invention relates to centrifugal pump technical field, specifically the packing ring of a kind of single stage single suction volute pump.
Background technology
At present, for the sealing between impeller and the pump shaft of single stage single suction volute pump, conventional has packing seal and mechanical seal two kinds, for gland sealed centrifugal pump, if tension is pressed to obtain in packing seal, meeting great load, filler quickly can warm up, the degree of wear of pump shaft is strengthened, it is thus desirable to often change, but press too loose, then can flowing water air inlet, cause using, when single stage single suction volute pump changes packing ring, owing to packing ring is an overall annulus, all parts beyond axle head packing ring all need to be disassembled, since so, packing ring is changed for client and bring very big inconvenience, sometimes also pump or motor disassembling are got off, when assembling, cause again not easily installing.
Summary of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, it is provided that a kind of novel structure, convenient disassembly, single stage single suction volute pump quick for installation packing ring.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of packing ring of single stage single suction volute pump, it is characterized in that being provided with packing ring and O, packing ring is to be put together by least two packing ring body, packing ring body is semi-circular, packing ring outer body circumference is provided with detent, it is respectively arranged at two ends with annular groove, packing ring body is radially provided with inlet opening, inlet opening is connected with detent, dismounting silk hole it is provided with in annular groove, to facilitate the fixing of packing ring body, O is stuck in the annular groove at packing ring body two ends and packing ring body is pieced together packing ring, reach replacing packing ring under the premise not removing other parts, solve when packing ring is changed and dismantled multipart trouble, reduce replacing construction, improve work efficiency.
Due to the fact that employing said structure, there is novel structure, convenient disassembly, the advantage such as quick for installation.
Description of drawings 1 is the structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Accompanying drawing labelling: O 1, packing ring body 2, detent 3, annular groove 4, inlet opening 5, dismounting silk hole 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of packing ring of single stage single suction volute pump, it is characterized in that being provided with packing ring and O 1, packing ring is to be put together by least two packing ring body 2, packing ring body 2 is in semi-circular, packing ring body 2 outer circumference is provided with detent 3, it is respectively arranged at two ends with annular groove 4, packing ring body 2 is radially provided with inlet opening 5, inlet opening 5 is connected with detent 3, dismounting silk hole 6 it is provided with in annular groove 4, to facilitate the fixing of packing ring body 2, O 1 is stuck in the annular groove 4 at packing ring body 2 two ends and packing ring body 2 is pieced together packing ring, reach replacing packing ring under the premise not removing other parts, solve when packing ring is changed and dismantled multipart trouble, reduce replacing construction, improve work efficiency.
The present invention is when mounted, first with O 1, packing ring body 2 is pieced together packing ring, again packing ring is installed to inside packing cavity, it is fixed on stuffing box with bolt through dismounting silk hole, during replacing, gland and filler are disassembled, O on packing ring body is taken out, again back-out dismounting silk hole in bolt, as long as packing ring can disassemble once going out packing cavity, convenient and swift, it is not necessary to the pump housing and electric motor end cap to be separated, only need to dismantle gland, without taking out from axle head, facilitate the replacing of packing ring.
Due to the fact that employing said structure, there is novel structure, convenient disassembly, the advantage such as quick for installation.
