Described fixed sleeving is welded tube or the antiwear composite ceramic steel pipe of diameter 100-500mm.Described moving casing is the welded tube of diameter 80-500mm, antiwear composite ceramic steel pipe or wear-resisting PE manage.The external diameter of described moving casing is less than the internal diameter 10-30mm of fixed sleeving.Described stuffing box packing is asbestos rope, packing or rag.
The described telescopic pipe with flange plate is macromolecule polythene flexible pipe or rubber hose, and diameter is 80-500mm.
The described moving casing length stretched in fixed sleeving is less than or equals the length of telescopic pipe.The internal diameter of described moving flange plate is greater than the external diameter 1-5mm of moving casing.
The beneficial effects of the utility model are:
1, the gap that between fixed sleeving and moving casing outer wall, useful stuffing box packing is filled up, and the telescopic pipe of flexibility all can reduce the coaxality requirement of the precision of sand pump level installation and the ore pulp inlet tube of fixed sleeving and sand pump.
2, flexible telescopic pipe eliminates the impact on sand pump pond and pre-buried fixed sleeving and flange plate tie point when sand pump vibrates, and has stopped the point of attachment spillage phenomenon brought because sand pump vibration, has decreased the loss of useful metal, improve operating environment.
3, moving casing can protect pre-buried fixed sleeving not frayed, and after moving casing wearing and tearing, replacing is very convenient.
