Abstract
The utility model provides a sealing device of a shaft end for water pumps. A labyrinth type water-sealing ring arranged between the outer packing of the water pump whose inner and outer packings are sealing types is used to substitute the inner packing. The water-sealing ring is provided with a water inlet distribution hole and a water cooling passage, and the inner part is provided with a labyrinth type channel. The utility model is suitable for all of the sealing type water pumps which can use the inner and the outer packings.
Description
The utility model relates to the manufacturing technology field of water pump, a kind of shaft end seal device of water pump specifically.
At present, the water pump that uses in the factory all is to adopt inside and outside packing to seal as Sh type water pump.Because it is tight excessively that interior packing easily forms sealing, press water is let out less than in the pump, thereby act on inside and outside packing, cause external leakage, especially run to certain hour, packing corruption or counterpart are not tight, current wash away for a long time, and the inner disc velamen all washes away, and the gap increases, moisture film destroys and does not have seal action, thereby causes leakage, current swing and the phenomenon of not fetching water.When above two kinds of situations took place, tight packing then caused the axle sleeve rapid wear, until can't working, or blocked blue gland fracture, blocked blue bolt and threaded off, and fracture is forced to the maintenance of disintegrating.
The purpose of this utility model provides the shaft end seal device of the water pump of packing in a kind of need not, and reduces tight packing number of times, reduces the wearing and tearing of axle sleeve.
The technical solution of the utility model is as follows:
Packing place in water pump is former, between packing and the pressure release outside just cover by adorning a mazy type seal cage.The effect of this seal cage is identical with former interior packing effect.Its structure is, in the seal cage the inside mazy type conduit arranged, and inlet distribution hole and cooling water passage are arranged.When pump operation, can form the steady pressure moisture film, thereby play seal action.
The utility model has the advantages that: reduced the number of times of tight packing, can reduce the axle sleeve wearing and tearing and prolong the cycle of disintegration overhaul; Shorten simultaneously the axle be length, reduce cost; Also be better than pump with mechanical seal, because of disintegrating after the damage of mechanical pump Sealing, could change, workload is big.
Below in conjunction with accompanying drawing the utility model is further explained:
Fig. 1 is the water pump that the mazy type seal cage is housed;
Fig. 2 is the structural representation of mazy type seal cage;
Fig. 3 is the left view of Fig. 2;
As we know from the figure, between the outer packing 3 of water pump and pressure release cover 10 by a mazy type seal cage 9 is housed.Six inlet distribution holes 15 and four cooling water passages 17 are arranged on the seal cage 9, mazy type conduit 16 is arranged in the seal cage the inside.Other sign is respectively pump shaft 1 among the figure, and axle sleeve locknut 2 blocks the blue nut 5 of blue bolt 4 tight cards, the blue gland 6 of card, pump cover 7, sealing water pipe 8, axle sleeve 11, impeller 12, key 13, pump lower body 14.
During fabrication, also mazy type seal cage 9 and pressure release cover 10 can be fused.
The sealing device also can be used for the shaft end seal of vertical, horizontal various model pumps, as long as principle is identical all applicable.
Claims (3)
1, a kind of shaft end seal device of water pump comprises that the outer packing of axle sleeve, card are blue, sealing water pipe, pressure release water jacket, and it is characterized by between the outer packing of water pump overlaps with pressure release has a mazy type seal cage; There are inlet distribution hole, cooling water passage, seal cage the inside that the mazy type conduit is arranged on the seal cage.
2, the shaft end seal device of a kind of water pump as claimed in claim 1, it is characterized by has six inlet distribution holes and four cooling water passages on the described mazy type seal cage.
3, the shaft end seal device of a kind of water pump as claimed in claim 1 is characterized by the mazy type seal cage and can be linked as one with the pressure release cover.
