Description
Technical field:
The utility model relates to the pump field, refers more particularly to a kind of new packing seal arrangement.
Background technique:
Existing water pump packing mode has packing filling sealing commonly used and the sealing of mechanical metal, packing filling is sealed in the water pump operation process, the air horsepower that friction between packing and the axle sleeve consumes is big, and it is also quite serious to axle sleeve wearing and tearing and leakage phenomenon, just needed to change packing and axle sleeve in per two months, can not sustainable high efficiency turn round, not only uneconomical but also unreliable.Though machinery metal sealing leakage rate is quite little, life cycle long (generally can reach more than 1 year), but the complete cost of mechanical seal is very high, mechanism's very complicated, have deviation very big to the water pump operation influence during installation slightly, must disintegrate to water pump during maintenance and just can carry out, workload greatly increases, thereby influenced normal production, reduced social benefit and economic benefit of enterprises.
Summary of the invention:
The purpose of this utility model provides a kind of new packing seal arrangement that turns round steadily, can improve sealability and working life, cuts down the consumption of energy.
The utility model is achieved in that a kind of new packing seal arrangement, comprise pump cover, seal ring, axle sleeve, pump shaft, it is characterized in that: described pump shaft is provided with axle sleeve, and the axle sleeve left end is provided with impeller, is provided with seal ring, new packing sealing, sealing gland on the axle sleeve from left to right; Be provided with " K " RunddichtringO in the sealing gland, be arranged with pump cover on the seal ring, the pump cover right side is provided with sealing gasket and machine sealed cover and is fastenedly connected by hexagon socket head cap screw, machine sealed cover and axle sleeve, seal ring, machine sealed cover are formed Seal cage, be provided with the new packing sealing in the Seal cage, be provided with the dottle pin circle between machine sealed cover and the sealing gland, by bolt machine sealed cover, dottle pin circle, sealing gland three closely are joined together to form a cooling water tank, the dottle pin circle is provided with the cooling water nozzle, is provided with filter screen in the cooling water tank
The utility model is rational in infrastructure, turns round steadily, has improved sealability and working life, has reduced energy consumption.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure 1, pump cover, 2, seal ring, 3, sealing gasket, 4, hexagon socket head cap screw, 5, the machine sealed cover, 6, the dottle pin circle, 7, sealing gland, 8, filter screen, 9, " K " RunddichtringO, 10, axle sleeve, 11, new packing sealing, 12, pump shaft, 13, bolt, 14, cooling water nozzle, 15, impeller nut, 16, impeller.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, a kind of new packing seal arrangement, comprise pump cover 1, seal ring 2, axle sleeve 10, pump shaft 12, it is characterized in that: described pump shaft 12 is provided with axle sleeve 10, axle sleeve 10 left ends are provided with impeller 16, are provided with seal ring 2, new packing sealing 11, sealing gland 7 on the axle sleeve 10 from left to right; Be provided with " K " RunddichtringO 9 in the sealing gland 7, be arranged with pump cover 1 on the seal ring 2, pump cover 1 right side is provided with sealing gasket 3 and machine sealed cover 5 and is fastenedly connected by hexagon socket head cap screw 4, machine sealed cover 5 and axle sleeve 10, seal ring 2, machine sealed cover 5 is formed Seal cage, be provided with new packing sealing 11 in the Seal cage, be provided with dottle pin circle 6 between machine sealed cover 5 and the sealing gland 7, by bolt 13 with machine sealed cover 5, dottle pin circle 6, sealing gland 7 threes closely are joined together to form a cooling water tank, dottle pin circle 6 is provided with cooling water nozzle 14, is provided with filter screen 8 in the cooling water tank.During concrete enforcement, the filler that adopts in the utility model packing seal mixes a kind of clay shape material of forming by four kinds of different materials such as the KEVLAR fiber that isozygotys, highly purified graphite, teflon organic encapsulant.Machine sealed cover and axle sleeve, seal ring, machine sealed cover are formed Seal cage, and the high-temperature resistant fiber filler is equipped with at the Seal cage two ends, and intermediate portion injects clay shape filler, is provided with inlet at the machine sealed cover, and filler injects Seal cage by special tool; Packing cavity contacts with medium near an end of impeller, cool off water nozzle on the other end cooling water tank and connect cooling water and cool off, so the two ends of packing cavity all can not produce high temperature and the damaged fiber filler.Clay shape filler has very strong plasticity in the utility model; in the movement process of axle; can tightly be wrapped on the axle sleeve; and along with axle sleeve is done rotation synchronously; form one " rotating layer "; this " rotating layer " keeps relative static with axle sleeve; along with the diameter of " rotating layer " progressively increases; axle will progressively weaken the winding ability of fiber, and all the other fillers are relative static with the Seal cage maintenance, and the branch aspect is sheared in one of formation in the middle of filler like this to form one " motionless layer "; rather than between filler and the axle sleeve; thereby namely reach the purpose of sealing, effectively avoided the wearing and tearing of axle sleeve again, protected axle sleeve.This clay shape filler, because intermolecular force is very little, its frictional force is very little, so also very little to the air horsepower loss, have only about 22% of packing_seal, namely be 2%～3% of air horsepower, greatly reduce power consumption, improved the efficient of water pump, ensure effectively to produce and save energy and reduce the cost.Even having, this packing seal leaks when needing repairing; it can not shut down reparation; only need directly to packing cavity, to inject the new clay shape filler of a part from inlet is installed, greatly reduce maintenance load, even axle sleeve has some wearing and tearing; owing to be the ring-type wearing and tearing; the rotating layer of filler can tightly wrap on the axle sleeve all the time, keeps relative static filler with axle sleeve, reaches sealing effect equally; this sealing makes the equipment operation period prolong greatly, even the several years all need not to carry out bigger maintenance.
