Abstract
The utility model relates to the technical field of centrifugal pumps, particularly to a packing ring of a single stage single suction centrifugal pump, which is characterized in that the centrifugal pump is provided with a packing ring and an O-ring, the packing ring is formed by joining at least two packing ring bodies, the packing ring bodies are annular, a positioning groove is arranged on the outer circumference of each packing ring body, an annular groove is arranged at each end of each packing ring body, a water inlet hole is arranged on each packing ring body in the radial direction and is communicated with the positioning groove, a dismounting screw hole is arranged inside each annular groove to facilitate the fixation of the packing ring body, and the O-ring is clamped in the annular grooves at the two ends of each packing ring body to join the packing ring bodies into the packing ring, so as to achieve the purpose of replacing the packing ring on the premise of not dismounting other components. The packing ring of a single stage single suction centrifugal pump provided by the utility model eliminates the trouble that too many components are dismounted for replacing the packing ring, reduces replacement time, and improves work efficiency.
Description
Technical field
The utility model relates to the centrifugal pump technical field, specifically a kind of packing ring of single stage single suction volute pump.
Background technique
At present, for the impeller of single stage single suction volute pump and the sealing between the pump shaft, commonly used have two kinds of packing seal and mechanical seals, as far as the gland sealed centrifugal pump; If packing seal press tension, can strengthen load, filler can warm up very soon; The degree of wear to pump shaft strengthens, and therefore needs often to change, but presses too loose; Then can the flowing water air inlet, cause and can not use, when single stage single suction volute pump is changed packing ring; Because packing ring is a whole annulus, need all component beyond the axle head packing ring are all disassembled, changed packing ring for the client since like this to have brought very big inconvenience; Sometimes also to disassemble pump or motor, when assembling, cause again being difficult for installing.
Summary of the invention
The purpose of the utility model is the deficiency that solves above-mentioned existing technology, and the packing ring of a kind of novel structure, convenient disassembly, single stage single suction volute pump quick for installation is provided.
The utility model solves the technological scheme that its technical problem adopted:
A kind of packing ring of single stage single suction volute pump is characterized in that being provided with packing ring and O shape circle, and packing ring is to be put together by at least two packing ring bodies; The packing ring body ringwise, packing ring body outer circumference is provided with positioning groove, two ends are respectively equipped with annular groove; The packing ring body radially is provided with the water inlet, and the water inlet is connected with positioning groove, is provided with dismounting silk hole in the annular groove; To make things convenient for the fixing of packing ring body; O shape is enclosed in the annular groove that is stuck in packing ring body two ends and with the packing ring body and is pieced together packing ring, has reached under the prerequisite of not removing other parts and has changed packing ring, has solved and has dismantled multipart trouble when packing ring is changed; Reduce the replacing time, improved working efficiency.
The utility model is owing to adopt said structure, has novel structure, convenient disassembly, advantage such as quick for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Reference character: O shape circle 1, packing ring body 2, positioning groove 3, annular groove 4, water inlet 5, dismounting silk hole 6.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Shown in accompanying drawing, a kind of packing ring of single stage single suction volute pump is characterized in that being provided with packing ring and O shape circle 1; Packing ring is to be put together by at least two packing ring bodies 2, packing ring body 2 ringwise, packing ring body 2 outer circumference are provided with positioning groove 3; Two ends are respectively equipped with annular groove 4, and packing ring body 2 radially is provided with water inlet 5, and water inlet 5 is connected with positioning groove 3; Be provided with a dismounting silk hole 6 in the annular groove 4, making things convenient for the fixing of packing ring body 2, O shape circle 1 is stuck in the annular groove 4 at packing ring body 2 two ends and with packing ring body 2 and pieces together packing ring; Reached under the prerequisite of not removing other parts and changed packing ring; Solved when packing ring is changed and dismantled multipart trouble, reduced the replacing time, improved working efficiency.
The present invention earlier pieces together packing ring with O type circle 1 with packing ring body 2 when mounted, packing ring is installed to inside the packing cavity again; Pass dismounting silk hole with bolt and be fixed on the Stuffing box, during replacing Gland and filler are disassembled, the O type circle on the packing ring body is taken out; Back-out and dismantle the bolt in the silk hole, packing ring is as long as can disassemble once going out packing cavity, and is convenient and swift; Need the pump housing and electric motor end cap not separated; Only need the dismounting Gland, need not to take out, made things convenient for the replacing of packing ring from axle head.
The utility model is owing to adopt said structure, has novel structure, convenient disassembly, advantage such as quick for installation.
