Embodiment Construction
[0008] Such as figure 1 As shown, this embodiment includes a packing gland 4 and a stuffing box 5, the stuffing gland 4 is connected to the outer wall of the shaft sleeve 2, the stuffing box 5 is connected to the stuffing gland 4 through bolts 3, and the feature is that the stuffing box 5 The filler is mud-like, which is a mixture of synthetic Kevlar fibers, polytetrafluoroethylene, and organic sealants.
[0009] Normally, it is necessary to stop the pump for operation, but the present invention does not need to stop the pump for operation, and can directly add filler with a filler gun.

The device comprises a packing gland (4), stuffing box (5), packing gland (4) and sleeve (2) the outer wall connection, stuffing box (5) by a bolt (3) and packing gland (4), the stuffing box (5) of the filler was mashed by synthetic Kevlar, Teflon, and organic sealants mixture.
Description
technical field [0001] The invention relates to a sealing device of a double-suction pump, which comprises a shaft sleeve, a packing gland and a stuffing box. The stuffing gland is connected to the outer wall of the shaft sleeve, and the stuffing box is connected to the stuffing gland through bolts. Background technique [0002] Double suction pump is a kind of rotating equipment, there must be a gap between the pump shaft and the pump casing, in order to prevent the liquid from flowing out of the pump, a sealing device is provided between the shaft and the pump casing; as the equipment is used for a long time, the shaft sleeve Severe wear and tear, frequent water ingress into the bearing box causes oil emulsification and deterioration, resulting in bearing damage. The existing sealing device often leaks oil, the spare parts consumption rate is high, and maintenance is frequent. . Contents of the invention [0003] The object of the present invention is to provide a doubl...
