Abstract
[Summary]
Present device refers to cooling material compulsion circulation of pump and slurry inflow prevention equipment of sealing surface.
Coolant compartment of coolant circulation in the internal sealing section, which formed in pump shaft's sleeve, and coolant compartment of coolant circulation in the external sealing section, which is formed in coolant compartment's sleeve surface, is formed in spiral circulation. And due to the pressure of coolant's helical circulation, frictional surface, which is formed in the sealing section from compressed substance, is smoothed. It protects sealing section's frictional surface with cooling effect in the coolant compartment and improves the function of sealing section.

[Construction of Device]
Coolant inner sleeve (4) is installed between shaft sleeve (3) in pump shaft (1)'s internal sealing section (2) and sealing section cover (2a). Spiral coolant compartment (5) is formed due to spiral home (3a)(4a), which is formed in shaft sleeve (3)'s external surface and coolant inner sleeve (4)'s internal surface. External sealing section (8), which has spiral coolant compartment (7) formed by spiral home (7a)(7b) between shaft sleeve (3)'s outer surface (3b) and coolant inner sleeve (4)'s inner side, is installed.
And, with the end of spiral coolant compartment (7)'s interval (9) it is composed to funnel with the pump compartment ( 10).
Slurry inflow is prevented in internal sealing section (2) and external sealing section (8) of the pump compartment (10) by mechanism 1 and 2. <Mechanism 1> In internal sealing section (2), coolant is circulated to coolant storage tank (13) by flowing coolant from coolant circulation intake (11) to coolant circulation outlet (12).
<Mechanism 2>
In external sealing section (8), substance in pump compartment (10) is flowed outward to interval (9) by flowing inward to external sealing section's coolant circulation intake (IS) through the separator (14).
Coolant, which is compulsively circulating spiral coolant compartment (5) of internal sealing section (2), smoothes the condition of internal sealing section (2)'s surroundings with helical circulation pressure. Coolant, which is compulsively circulating spiral coolant compartment (7) of external sealing section (8), smoothes the severe condition of external (8) and internal sealing section (2)'s surroundings pressured from pump compartment (10)'s substance with helical circulation pressure.
As a result, frictional surface of the sealing section is protected.
Drawing 3 shows other performance example of present device formed by external sealing section (8)'s cover (8a) as the pump body (6). It simpli fled external sealing section (8)'s structure without the external sealing section (8)'s cover ( 8a).
Drawing 4 shows another performance example of present device, preventing slurry inflow from pump compartment (10) to shaft sleeve (3) with helical circulation in the external sealing section (8). It simplified sealing equipment by installing only external sealing section (8) outside the shaft sleeve (3).
[Effect of Device) Coolant, which goes through the spiral coolant compartment (5) of internal sealing section (2) in pump shaft (1), sufficiently cools frictional surface by compulsive circulation with helical circulation. And coolant's outflow pressure smoothes the severe condition of internal sealing section (2)'s surroundings with helical circulation.
Coolant, which goes through the spiral coolant compartment (7) of external sealing section (8), sufficiently cools frictional surface by compulsive circulation with helical circulation. And it prevents inflow of substance and slurry toward sealing section of the pump compartment (10) by outward flow of coolant's outflow pressure to interval (9) with helical circulation. And it improves the function of sealing section by protecting the frictional surface smoothing severe condition of sealing section.
In addition, present device applies to all sealing section of pumps transferring gas, air-pressure, vacuum or solid material, and substances.
