Description
Technical field
The utility model belongs to centrifugal pump technical field, particularly a kind of seal arrangement of Novel major axis pump.
Background technique
At present, long-shaft pump is widely used in pumping medium from deep-well, under liquid, length several meters tens meters at most at least, as shown in Figure 1, the pump shaft 7 of long-shaft pump is provided with bearing support, sliding bearing 6 is provided with in bearing support, by bolt 2, plain washer 3, spring washer 4 by gland 5 fixed bearing block, coordinating between pump shaft 7 with sliding bearing 6 does not adopt axle sleeve mode, after pump shaft is worn and torn, directly can only change pump shaft, add the cost of pump maintenance; Traditional long-shaft pump sliding bearing 6 directly and medium contact, does not have Seal cage, when water pump works under severe conditions, increases the wearing and tearing of sliding bearing 6, pump shaft 7; What adopt between sliding bearing 6 and pump shaft 7 is loose fit, and when working medium difference, in use a period of time, pump shaft 7 and sliding bearing 6 gap increase, and the stability of water pump operation is reduced.
Summary of the invention
The purpose of this utility model to solve the problems of the technologies described above.
The purpose of this utility model is achieved in that a kind of seal arrangement of Novel major axis pump, comprise jack shaft bolster, bolt, pump shaft, upper press cover, jack shaft bolster center is provided with bearing support, it is characterized in that: be provided with axle sleeve between described pump shaft and bearing support, two ends, axle sleeve left and right are all fixed on pump shaft by the Cock screw of circumference uniform distribution on several external cylindrical surface; Screw bolt passes lower cover, packing washer are fixed on the left side of bearing support, are provided with sliding bearing between bearing support and axle sleeve; Sliding bearing left end is provided with seam, and the internal tooth of packing washer is arranged in seam; Be provided with two K type circles between sliding bearing left end and the step surface of lower cover, two K type circles are arranged back-to-back; Bearing washer is provided with between sliding bearing right-hand member and the step surface of inner hole of bearing seat.
Described upper press cover is bolted on the right side of bearing support, is provided with two K type circles between upper press cover and axle sleeve, and two K type circles are arranged back-to-back.
Described K type circle adopts PE antiwear and anticorrosive material.
The utility model good airproof performance, improves the stability of long-shaft pump, improves the wear resistance of pump shaft, sliding bearing, extend the working life of long-shaft pump, the material that can reduce pump drops into, and reduces cost of production, applies and have good economic and social benefit.
Accompanying drawing explanation
Fig. 1 is the long-shaft pump sliding bearing internal stent structural representation of prior art.
Fig. 2 is internal structure schematic diagram of the present utility model.
In figure: 1. jack shaft bolster; 2. bolt; 3. plain washer; 4. spring washer; 5. gland; 6. sliding bearing; 7. pump shaft; 8. axle sleeve; 9. Cock screw; 10. lower cover; 11.K type circle; 12. packing washers; 13. bearing washers; 14. upper press covers.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
A kind of seal arrangement of Novel major axis pump, comprise jack shaft bolster 1, bolt 2, pump shaft 7, upper press cover 14, jack shaft bolster 1 center is provided with bearing support, be provided with axle sleeve 8 between described pump shaft 7 and bearing support, axle sleeve about 8 two ends are all fixed on pump shaft 7 by the Cock screw 9 of circumference uniform distribution on several external cylindrical surface; The left side that bolt 2 passes lower cover 10 successively, packing washer 12 is fixed on bearing support, is provided with sliding bearing 6 between bearing support and axle sleeve 8; Sliding bearing 6 left end is provided with seam, and the internal tooth of packing washer 12 is arranged in seam; Be provided with two K type circles, 11, two K type circles 11 between the step surface of sliding bearing 6 left end and lower cover 10 to arrange back-to-back; Bearing washer 13 is provided with between sliding bearing 6 right-hand member and the step surface of inner hole of bearing seat; Described upper press cover 14 is bolted on the right side of bearing support, is provided with two K type circles, 11, two K type circles 11 and arranges back-to-back between upper press cover 14 and axle sleeve 8; Described K type circle 11 adopts PE antiwear and anticorrosive material.
During concrete enforcement, 1), in pump shaft 7 and sliding bearing 6 cooperation place of long-shaft pump install axle sleeve 8 additional, whole pump shaft can not be changed because of the wearing and tearing of axle sleeve 8, thus reduce cost; 2), by sliding bearing chamber do Seal Design, ensure that pump uses under severe conditions, reduce the wearing and tearing of sliding bearing 6, axle sleeve 8, pump shaft 7; 3), Seal cage adopts K type circle 11 to seal, each sliding bearing 6 is equipped with two groups, often organize two, and mounting type is a positive and a negative to be installed, to prevent Seal cage inner cooling water from leaking or pump intraluminal medium inflow Seal cage, this structure can not only reduce sliding bearing 6, axle sleeve 8, pump shaft 7 wear conditions, because K type circle 11 " armful " is on pump shaft 7, can play good stablizing effect equally.
Obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
