Abstract
A sealing filler for water pump is prepared from fibres (1-1.6%), graphite powder (14-18), teflon resin (16-20), mica powder (18-22) and polyacrylic sealing agent (44-48) through mixing to obtain semi-solid filler. Its advantages are no abrasion to axle sleeve, high plasticity, durable and reliable sealing, and low friction resistance.
Description
The present invention relates to a kind of lock packing of pump, be specially adapted to the sealing of water pump.
The packing_seal that the stuffing box of existing water pump extensively adopts the differing materials braiding to form, because trim is between packing and axle, friction resistance is big, causes the packing_seal mode to be leaked for a long time, and work-ing life is short, and the wearing and tearing axle sleeve is pacified problems such as tearing inconvenience open.When the water pump stuffing box adopted wear ring, model was not general, and running resistance is big, and duration of service is short; If adopt mechanical seal, versatility is bad, changes more numerous and diverse.The shaft cavity seal packing for water pump that other 94105406.3 patent applications propose; by waste leather, dried matter sawdust, grease composition; it has improved the problem that above three kinds of sealing means exist to a certain extent, but still has the wearing and tearing axle sleeve, can not shut down the problem of reparation.
The present invention is directed to the problems referred to above, a kind of semi-solid water pump packing is provided, fundamentally solves the leakage and the wear problem of the shaft cavity seal packing for water pump existence of packing, seal ring seal, mechanical seal, 94105406.3 patent applications proposition, the present invention forms trim in filler, axle sleeve does not does not wear and tear, fabulous plasticity-is arranged, and Intermolecular Forces is little, and sealing effectiveness reliably and with long-term, friction resistance is little, power consumption is low, can onlinely repair, thus the maintenance cost and the labour intensity of reduction pump.
Of the present inventionly relate to a kind of water pump packing, its component and content are: fiber 1～1.6%, and Graphite Powder 99 14～18%, teflon resin 16～20%, mica powder 18～22%, polyacrylic acid sealing agent 44～48%, described percentage ratio are weight percentage.
The fiber that water pump packing adopted that the present invention relates to can be aramid fiber or tetrafluoroethylene.
The water pump packing preparation method who the present invention relates to is: fiber was immersed in the polyacrylic acid sealing agent after 5-10 hour, puts into mixing roll, and add teflon resin successively, Graphite Powder 99, the mixing one-tenth semisolid of mica powder.
The present invention has compared following advantage with other water pump packing material and sealing means:
1, filler part in stuffing box is wrapped in axle sleeve and forms moving layer, and another part is static, forms motionless layer, and trim is formed at filler inside and not between filler and axle sleeve, can produce wearing and tearing to axle sleeve like this;
2, filler has fabulous plasticity-, and Intermolecular Forces is little, and sealing effectiveness does not have and leaks reliably and with long-term, reduces maintenance cost;
3, Intermolecular Forces is little in the filler, and friction resistance is little, and power consumption is low;
4, adopt the High Pressure Gun injection, install simple, can be online during unscheduled maintenance labour intensity low;
5, have wide range of applications.
Following mask body provides the realization embodiments of the invention:
Embodiment 1: aramid fiber 1.2% was immersed in the polyacrylic acid sealing agent 46.8% after 5 hours, puts into mixing roll, and add teflon resin 17%, Graphite Powder 99 16%, mica powder 19% mixing one-tenth semisolid successively.
Embodiment 2: polytetrafluoroethylene fiber 1.5% was immersed in the polyacrylic acid sealing agent 44.5% after 10 hours, puts into mixing roll, and add teflon resin 20%, Graphite Powder 99 14%, mica powder 20% mixing one-tenth semisolid successively.
During use, the woollen yarn knitting end ring is set up at the stuffing box two ends, with High Pressure Gun the semi-solid state lock packing is injected in the stuffing box from injection port to get final product.
Claims (2)
1, a kind of water pump packing, its component and content are: fiber 1～1.6%, Graphite Powder 99 14～18%, teflon resin 16～20%, mica powder 18～22%, polyacrylic acid sealing agent 44～48%, described percentage ratio are weight percentage.
2, water pump packing as claimed in claim 1 is characterized in that described fiber is aramid fiber or tetrafluoroethylene.
