Oil seal ring is placed in inside stuffing box against mop, and for the oil sealing ring set on axle sleeve, the tetrafluoro packing abuts oil seal ring
It is placed in inside stuffing box, the tetrafluoro packing covers on axle sleeve, and the tetrafluoro packing is placed in by gland component compression
Inside stuffing box, the accessory impeller and stuffing box use clearance seal.
Preferably, mop and axle sleeve are interference fit.
Preferably, gland and stuffing box are fixed by bolt and nut.
Preferably, screw-down type grease cup is connected through a screw thread in stuffing box, is injected and is lubricated to oil seal ring by screw-down type grease cup
Oil.
Preferably, stuffing box and accessory impeller use clearance seal.Can balancing axial thrust, reduce sealing cavity pressure, prevent
Grain enters sealing position and damages axle envelope.
Preferably, the mop is placed in stuffing box most the inside, for preventing impurity from entering at axle envelope.
Preferably, the oil seal ring is placed in inside stuffing box against mop, for lubricating packing seal structure.
Preferably, the filler is placed in inside filler against oil seal ring by gland compression.
Preferably, the screw-down type grease cup is directly injected into molybdenum disulfide to oil seal ring and is lubricated to axle envelope, without external
Flushing water is rinsed axle envelope component.
Preferably, the screw-down type grease cup is directly injected into molybdenum disulfide to oil seal ring and is lubricated to axle envelope, without external
Flushing water is rinsed axle envelope component.
Preferably, the axle sleeve improves 2 times using martensitic stain less steel heat treatment surface ceramic platingv processing, service life.
Preferably, the accessory impeller uses camber blades, improves abrasion-resistance compared with previous prismatic blade.
The utility model has the following beneficial effects:
The structure uses mop, oil seal ring and tetrafluoro packing combined sealing structure, straight from screw-down type grease cup to oil seal ring
Injection molybdenum disulfide is connect to be lubricated axle envelope, mop uses a point half formula structure, and it is convenient for disassembly and assembly, it is safe and reliable to operation；It is whole
Structure is simple, convenient for disassembly and assembly, the advantages that running smoothly, is safe and reliable, by mop and accessory impeller combination sealing, thus effectively
Prevent slurry enter axle envelope damage packing.
