Description
Technical Field
The present utility model relates to a swirl pump.
Background
The vortex pump comprises a pump body, a pump cover and a pump shaft, wherein the pump cover is connected to the pump body, a cavity is formed between the pump cover and the pump body, one end of the pump shaft is connected with an impeller, the impeller is positioned in the cavity, a mechanical seal is sleeved on the pump shaft to prevent medium leakage, a cooling system and a lubricating system are required to be added to cool and lubricate the mechanical seal for preventing the sealing surface from being damaged, in addition, when the sealing performance of the mechanical seal is reduced, the mechanical seal is required to be detached for repair, and the maintenance is inconvenient; there is therefore a need for improvement.
Disclosure of utility model
In view of the above problems, the present utility model provides a vortex pump with convenient seal maintenance, which can omit a system for cooling a sealing member on the basis of ensuring sealing performance; the maintenance of sealing performance can be facilitated.
The technical scheme is that the vortex pump convenient to seal and maintain comprises a pump body 6, a pump cover 1 is connected to the left end of the pump body in a sealing manner, an impeller 2 is arranged in the pump body, the left end of a pump shaft 4 is fixedly connected with the impeller, the pump shaft is supported by a bearing 3, the bearing is arranged in a bearing chamber 5 of a right side wall 7 of the pump body, a sleeve 9 extends rightwards on the right side wall 7 of the pump body, a mud-shaped filler 10 is arranged between the sleeve and the pump shaft, a first filler ring 8 is arranged on the left side of the mud-shaped filler, a second filler ring 11 is arranged on the right side of the mud-shaped filler, the left end face of the first filler ring 8 is attached to the right side wall of the bearing chamber, the second filler ring 11 is pressed by a pressing cover 12, and the model of the mud-shaped filler is SR900.
The mud-like packing seal is characterized in that: the pump is simple to install, has no leakage, is reliable in sealing, has no abrasion to the pump shaft, and does not need cooling and lubrication.
The utility model has the beneficial effects that on the basis of ensuring the sealing performance, a system for cooling the sealing part and a lubrication system are omitted; the maintenance of sealing performance can be facilitated.

Description of the embodiments
The utility model provides a convenient vortex pump is maintained in seal, it includes pump body 6, the left end sealing connection of pump body has pump cover 1, be equipped with impeller 2 in the pump body, the left end and the impeller fixed connection of pump shaft 4, the pump shaft is supported by bearing 3, the bearing is installed in the bearing room 5 of the right side wall 7 of pump body, extend a sleeve 9 to the right on the right side wall 7 of pump body, be equipped with the mud form packing 10 between sleeve and the pump shaft, the left side of mud form packing is equipped with first packing ring 8, the right side of mud form packing is equipped with second packing ring 11, the left end face of first packing ring is pasted with the right side wall of bearing room, the external diameter of first packing ring and second packing ring cooperatees with the internal diameter of sleeve, leave the clearance between the interior circle of first packing ring and second packing ring and the pump shaft, the left end face of gland 12 flange extends to the left and has the bulge loop, the bulge loop is inserted in the sleeve and is pasted with the second packing ring, the sleeve right end extends there is the flange, be connected with bolt between flange of sleeve and the gland flange, screw down the bolt can compress tightly mud form packing, mud form packing is SR900. The right end of the pump shaft is connected with a rotating shaft of a motor (not shown in the drawing)
The mud-like packing seal is characterized in that: the pump is simple to install, has no leakage, is reliable in sealing, has no abrasion to the pump shaft, and does not need cooling and flushing.
The mud packing seal is also characterized by on-line repairability after wear, for which: radial injection holes 14 are symmetrically arranged on the wall of the sleeve 9, the number of the injection holes is 8-12, the injection holes are positioned at the middle part of the mud filler, and the opening parts of the injection holes are hermetically screwed with screw plugs 13. When the sealing performance is reduced, the mud-shaped filler can be extruded into the sleeve by a certain pressure through the injection hole in a successive way, and the abrasion loss is compensated; the screw thread is blocked after injection is finished; this enables maintenance of sealing performance without dismantling the sealing member.
