Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.
As shown in Fig. 1~2, a kind of sealing structure for submerged pump, including submerged pump ontology 1 are provided, in submerged pump ontology
Front end is provided with rotary blade 2, is respectively arranged with lip seal chamber 3 in the rear end of submerged pump body interior rotary blade and fills out
The double sealing structure that material seal chamber 4 is formed, wherein packing seal chamber are arranged in the front end of lip seal chamber；In submerged pump ontology
It is additionally provided with closing mounting hole 5 at upper lip seal chamber and packing seal chamber position, the outside of closing mounting hole is provided with envelope
Close cover board 6；It is further opened with spout hole 7 in the rear end of submerged pump ontology, which is connected to lip seal chamber and filler is close
At the double sealing structure position that envelope chamber is formed.
The lip seal chamber is using single lip seal structure.
The packing seal chamber includes stuffing box 8, is internally provided with filler 9 in stuffing box, is also set on the outside of stuffing box
It is equipped with gland 10.
It is additionally provided with pipe fitting 11 on stuffing box, seal cage 12 is provided in stuffing box, seal cage is arranged in filler
