Abstract
The utility model relates to a cartridge packing seal box for a pump, comprising a front cover, a pump body, an impeller and a shaft sleeve, wherein a packing box is arranged between the pump body and the shaft sleeve, the packing box is filled with packing, a water seal ring is arranged in front of the packing, and a packing gland cover is arranged behind the packing, the impeller is arranged between the front cover and the pump body, and the shaft sleeve is connected with a shaft by thread, so the defect of the old pump can be basically resolved, the maintenance is more convenient, at the same time, the shaft sleeve can be more firmly connected with the impeller.
Description
Technical field:
The utility model relates to a kind of pump, particularly relates to a kind of pump unit loading type packing seal case.
Background technique:
At present, the sealing means of conventional pump always is contained in filler in the packing cavity in the pump cover, fixes with Gland again, such design makes the wearing and tearing of filler or pump shaft easily, normally use often repair and replacement, and the loading and unloading packing cavity is very difficult, not only time-consuming, and is difficult to reach the precision of design.And the impeller of pump is fixed, and generally also is to adopt impeller nut to fix, and pump is long service time one, and impeller is easy to become flexible, and causes a lot of inconvenience for normal production.
Summary of the invention;
The purpose of this utility model will provide a kind of novel pump unit loading type packing seal case exactly, and it can overcome the existing defective of above product well.The purpose of this utility model is to realize like this, a kind of pump is made up of protecgulum, the pump housing, impeller, axle sleeve with unit loading type packing seal case, it is characterized in that: between the pump housing and axle sleeve, be provided with stuffing box, the filler of in described stuffing box, packing into, front at filler is provided with seal cage, in the back of filler Gland is set; Be provided with impeller between the protecgulum and the pump housing, axle sleeve is connected with axle by screw thread with impeller.The utility model is simple in structure, and is easy for installation, and impeller is not easy to come off when operation, and is easy to maintenance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
1. protecgulum 2. impellers 3. pump housings 4. axle sleeves 5. seal cages 6. stuffing boxes 7. fillers 8. Glands are 9.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing
In Fig. 1, a kind of pump of the utility model is made up of protecgulum, the pump housing, impeller, axle sleeve with unit loading type packing seal case, it is characterized in that: between the pump housing and axle sleeve, be provided with stuffing box, the filler of in described stuffing box, packing into, front at filler is provided with seal cage, in the back of filler Gland is set; Be provided with impeller between the protecgulum and the pump housing, axle sleeve is connected with axle by screw thread with impeller.During concrete enforcement, filler is packed in the stuffing box, before and after it seal cage and Gland are set respectively then, forms a pump with unit loading type packing seal case, integral body can be easy for installation and removal like this, feasible keep in repair and nursing becomes easy and convenient.Axle sleeve and impeller are connected with axle by screw thread, the impacting force that two component are screwed added all the time between screw thread and the effect of friction, thus make impeller to be fixed on the axle reliably.
