Abstract
The utility model discloses a fixture for disassembling a sealing sleeve of a water outlet section of a centrifugal pump. The fixture is characterized by comprising a lower press plate, a jack positioned above the lower press plate, an upper press plate and a fastening bolt, wherein a plug is arranged above the jack; the upper end of the plug is provided with a circular boss which is inserted into the sealing sleeve and positioned at the lower end of the sealing sleeve; a bolt hole is formed in the circular boss; the lower end of the upper press plate is provided with a second circular boss which is inserted into and positioned at the upper end of the sealing sleeve; a downward through hole is formed in the upper press plate; and the fastening bolt can pass through the through hole in the upper press plate, and is screwed into the bolt hole in the plug to compact the upper press plate and the plug at the upper end and the lower end of the sealing sleeve. During use, the fixture can disassemble the sealing sleeve from the water outlet section of the centrifugal pump conveniently and quickly, and has the characteristics of convenience in disassembly, time saving and labor saving.
Description
Technical field
The utility model relates to a kind of centrifugal pump extracting tool, especially a kind of centrifugal pump water exit end stuffing box gland dismounting frock.
Background technique
In centrifugal pump, the pump shaft at its water exit end place is outside equipped with stuffing box gland, and the water that stuffing box gland is used to support pump shaft and guarantee water exit end can not enter into the motor place along axis hole.Stuffing box gland because and have pivoting friction wearing and tearing between the pump shaft, belong to easily damaged parts, usually need to change.Simultaneously, because stuffing box gland need play seal action, so cooperating between stuffing box gland and the water exit end body is very tight.Like this, when the dismounting stuffing box gland, very inconvenience is dismantled by manpower, generally needs effect in 2 hours, and generally needs two workmans to cooperate and could it be disassembled.
The model utility content
To the deficiency of above-mentioned existing technology, the utility model technical problem to be solved promptly is: how centrifugal pump water exit end stuffing box gland dismounting frock a kind of for convenience detach, time saving and energy saving is provided.
In order to solve the problems of the technologies described above, adopted following technological scheme in the utility model:
A kind of centrifugal pump water exit end stuffing box gland dismounting frock; Its characteristics are; Comprise press table, be arranged in the jack of press table top (this programme is to be benchmark with the working state for the narration in orientation), the jack top is provided with stopper; The stopper upper end has the round platform that can insert stuffing box gland and be positioned at the stuffing box gland lower end, and round platform is provided with bolt hole; Also comprise a top board, the lower end of top board has can insert and navigate to stuffing box gland upper end second round platform, also has a downward through hole on the top board; Also comprise a clamping bolt, said clamping bolt can pass the through hole on the top board and be screwed in the bolt hole of stopper and make top board and stopper be pressed on the two ends up and down of stuffing box gland.
In the dismounting frock of the utility model; During use; The two ends up and down of earlier adopting stopper, clamping bolt and top board to be fastened on stuffing box gland are one, and then adopt the assistant tool screw rod that press table is fixed on the lower end of stuffing box gland, adopt jack to withstand between press table and the stopper then; The startup jack can be communicated with stopper with stuffing box gland quickly and easily and top board ejects the centrifugal pump water exit end together.Wherein, because the jack that uses ejects, the required take-down time reduces in a large number, only needs just can it be taken apart in 5-10 minute, and only needs a people just can it be disassembled at present.For company has practiced thrift great amount of manpower and material resources, for the delivery cycle of product has been practiced thrift great amount of time.
In sum, the dismounting frock of the utility model during use, can take apart stuffing box gland quickly and easily in the centrifugal pump water exit end, have convenient disassembly, time saving and energy saving characteristics.
Description of drawings
Structural representation when Fig. 1 uses for the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the structure and the advantage of the utility model are done further to specify.
During practical implementation; The utility model structure is referring to Fig. 1, and a kind of centrifugal pump water exit end stuffing box gland dismounting frock comprises press table 1; Be arranged in the jack 2 of press table 1 top (this programme is to be benchmark with the working state for the narration in orientation); Jack 2 tops are provided with stopper 3, and stopper 3 upper ends have the round platform that can insert stuffing box gland 4 and be positioned at stuffing box gland 4 lower ends, and round platform is provided with bolt hole; Also comprise a top board 5, the lower end of top board 5 has can insert and navigate to stuffing box gland 4 upper ends second round platform, also has a downward through hole on the top board 5; Also comprise a clamping bolt 7, said clamping bolt 7 can pass the through hole on the top board 5 and be screwed into and make top board 5 and stopper 3 be pressed on the two ends up and down of stuffing box gland 4 in the bolt hole of stopper 3.
As shown in Figure 1, when this dismounting frock is used, need to adopt some screw rods 8, screw rod 8 upper ends are screwed in the assembling screw of lower end surface of centrifugal pump water exit end 6, and the lower end is fixed after passing the through hole that is arranged on the press table 1.And then on press table 1, install jack 2; Top board 5 and stopper 3 are fixed on the two ends up and down of stuffing box gland to be removed 4 through clamping bolt 7; The lower end of then stopper 3 being withstood in jack 2 upper ends; Start jack 2 and up push up, can be easily, quickly stuffing box gland 4 is ejected in the centrifugal pump water exit end 6.
