Wherein: 1. the packing gland comprises a packing gland 2, a compression bolt 3, packing 4, a packing chamber 5, a packing shaft sleeve 6, a transmission shaft 7, a central hole 8, a pressing ring 9, a compression groove 10 and a butt plate.
Detailed Description
Fig. 1 to 3 are preferred embodiments of the present invention, and the present invention will be further explained with reference to fig. 1 to 3.
As shown in figure 1, the deep well pump comprises a transmission shaft 6, a packing shaft sleeve 5 is sleeved outside the transmission shaft 6, and a packing chamber 4 is sleeved outside the packing shaft sleeve 5. And a containing cavity is formed between the inner ring of the packing chamber 4 and the outer ring of the packing shaft sleeve 5 at intervals. The packing 3 is filled in a containing cavity formed between the packing chamber 4 and the packing sleeve 5. After the packing 3 is filled, a packing gland 1 is arranged at the port of the packing 3, the packing gland 1 is simultaneously sleeved on the outer ring of the transmission shaft 6, two pressing bolts 2 are respectively arranged on two sides of the packing gland 1, the pressing bolts 2 penetrate through the packing gland 1 along the axial direction of the transmission shaft 6 and then are screwed into the packing chamber 4 to fix the packing gland 1, and meanwhile, the packing 3 is pressed in the packing chamber 4.
With reference to fig. 2 to 3, a center hole 7 for a transmission shaft 6 to pass through is formed in the center of the packing gland 1, two pressing grooves 9 with outer end openings are symmetrically formed in two sides of the packing gland 1, and two pressing bolts 2 respectively pass through the pressing grooves 9 in the two sides when the packing gland 1 is fixed. A pressing ring 8 is arranged on one side of the packing gland 1, and after the packing gland 1 is fixed, the pressing ring 8 is in contact with the outer end face of the outermost packing 3.
The packing gland 1 is split and is formed by oppositely butting two gland monomers with the same shape. Each single gland is provided with a semicircular notch, and the two single glands are butted to form the central hole 7. Two sides of the opening end of each single gland are respectively provided with a butt joint plate 10, and the butt joint plates 10 on the two sides are arranged in a vertically staggered mode. Because the two sides of the single gland are respectively provided with the butt-joint plates 10 which are arranged in a staggered manner, after the two single gland are butted oppositely, the butt-joint plates 10 at the two ends of the two single gland are overlapped in a staggered manner. And after the two gland monomers are butted, the two semicircular bosses are simultaneously butted to form the pressing ring 8.
The outer side of each butt joint plate 10 is respectively provided with a pressing groove 9, so that after the two butt joint plates 10 at the same end of the two gland monomers are overlapped along with the butt joint of the gland monomers, the two pressing grooves 9 at the same end are also overlapped up and down. Therefore, when the gland 2 is fixed, the same gland bolt 2 simultaneously passes through the gland grooves 9 of the two gland monomers. Therefore, when the gland 1 is fixed with the packing chamber 4, the compression bolt 2 simultaneously locks two gland monomers forming the gland 1.
Therefore, the split type packing gland in the application avoids the defect that the packing gland of a split structure in the prior art needs to be additionally provided with the locking bolt to lock each section of single body, and the locking bolt is installed in the direction perpendicular to the compression direction of the packing 3 when each section of single body is locked, so that the problem that the packing gland is difficult to dismantle due to compression deformation of the locking bolt in the prior art is fundamentally solved due to the omission of the locking bolt.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
