Further, bearing cooling water pipe 31 is positioned at pump shaft fuel tank 82.
Further, bearing cooling water pipe 31 is positioned at pump shaft fuel tank shell 81.
Further, the semi-open type runner 44 of hydraulic gland 4 is by narrow gradually wide screw-shaped flow paths.
Further, the semi-open type runner 44 of hydraulic gland 4 is radial inflow runner, and namely water outlet 43 is positioned at the inner side of flow passage ends.
Further, hydraulic gland 4 side is connected on the decompression lid 9 of Pulp pump, is bolted.
Further, the blade 51 of turbine 5 is semi-open type blade.
Beneficial effect: by the import and export in machine joint sealing body are become the centripetal semi-open type of distinctive efficient spiral with runner design, turbine design is become open type blade shape, and machine joint sealing to be sealed with machine and turbine is connected, make pump turbine when getting into smooth machine can be sealed sparge water and form longitudinal whirlpool, lift is superposed under the repeatedly effect of centrifugal force, reach and at import and export serial connection bearing cooling water pipe, and can finally receive the object of pump water tank use.Like this, even if under the work condition environment of lack of water, due to high-lift machine seal cooling water, only need one case water can meet the cooling circulating water sealed from Pulp pump bearing chamber to machine and work together, make the use of Pulp pump under lack of water operating mode more secure, whole mechanism is very simple and practical.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Fig. 1 to Fig. 6 is a kind of embodiment of the present utility model, wherein Fig. 1 is that utility model works mode is illustrated, black box 6 uses the utility model mechanism, machine seals external wash tub pipe and is concatenated into bearing cooling tube 31 and cools to bearing unit 83, is finally concatenated on water tank 1 and forms reflux cycle.
Fig. 2 and Fig. 3 is the structural principle signal of the utility model black box 6.With a Pulp pump sealed case mechanism for cooling water circulation turbine, comprise hydraulic gland 4, mechanical seal 61, open type blade turbine, baffle plate 7.Mechanical seal 61 is arranged in hydraulic gland 4, and wherein stationary ring is connected in hydraulic gland stationary ring groove, and rotating ring is fixed on axle by rotating seat.Open type blade turbine be enclosed within machine seal 61 peripheries be fixed by screws in machine envelope rotating seat on.Inside turbine 5, arrange baffle plate 7 near decompression lid place makes current focus in hydraulic gland runner.
Fig. 4 and Fig. 5 is the utility model hydraulic gland 4 structure, it is characterized in that, outside hydraulic gland stationary ring groove, be arranged with screw heart semi-open type runner 11, the narrow waterexit end of runner feed-water end is wide, from feed-water end to waterexit end helix gradual change.Feed-water end and centre, waterexit end arrange cut water 41 and separate current, runner feed-water end is provided with water intake 43, water intake 43 is arranged on hydraulic gland side runner feed-water end and machine seals between 61, and separate with runner and be not directly communicated with, runner waterexit end is provided with water outlet 42, and water outlet 42 is arranged on hydraulic gland side near mechanical seal 61 and is communicated with runner waterexit end is centripetal.
Fig. 6 is the utility model open type blade turbine schematic diagram, uses open type blade.
Pump drives turbine 5 to operate in the running, liquid in open type blade is thrown in the centripetal semi-open type runner 44 of spiral under centrifugal action, the pressure of blade interior reduces simultaneously, and liquid is again inhaled in blade from runner, liquid is produced and turns to identical longitudinal whirlpool 45 with turbine.This longitudinal whirlpool makes the liquid in runner repeatedly repeatedly return in blade, once again by centrifugal action, superposition like this, the centripetal semi-open type runner of spiral of hydraulic gland runner employing simultaneously, greatly strengthen the trend that import water is assembled to outlet, the lift that final generation is larger, be enough to the resistance overcoming bearing cooling water and machine envelope wash tub pipe, water tank is received in final series connection, even if reach the effect using a small amount of water also can meet cooling and rinse.And water intake and runner are not communicated with inlet's current adds to blade place continually after throwing away blade, due to the centripetal layout of water outlet, even if enter a small amount of bubble also can realize driving bubble to flow out with current, successfully achieving using the utility model only needs one case water can meet the situation of the cooling circulating water work of sealing from Pulp pump bearing chamber to machine, make the use of Pulp pump under lack of water operating mode more secure, whole mechanism is very simple and practical.
