Abstract
The utility model discloses a leakage proof centrifugal pump, comprising a shaft sleeve nut, an end cover with holes, a bearing, a bearing sleeve, a shaft sleeve A, a gland cover, a bearing body, a suction segment, a sealing ring, a vane wheel, a middle segment, a guide vane, a guide vane sleeve, a discharge segment, a balancing loop, a balancing plate, a gland container, a shaft sleeve B, a shaft, a round nut and an end cover without holes. The concave grove of the gland container which is positioned on the two ends of the centrifugal is provided with a Y shape wire sealing ring, the inner diameter of which is the same with the shaft diameter. The shaft passes through the Y shape wire sealing ring and tightly pressed and fixed the Y shape wire sealing ring through the shaft sleeve A and the shaft sleeve B. With the adoption of the structure of arranging the Y shape wire sealing ring inside the concave groove of the gland container of the centrifugal, the shaft can be tightly cooperated with the Y shape wire sealing ring, thereby ensuring no leakage when the centrifugal is in use. The utility model also has the advantages of simple structure and easy operation.
Description
Technical field
The utility model relates to a kind of improvement of water pump leakage proof device, particularly a kind of novel leakage proof centrifugal pump.
Background technique
Existing various water pump all adopts in the stuffing box body of pump and adds the effect that asbestos packing reaches sealing, prevent the water pump seepage, but adopt the asbestos packing sealing can only use several usefulness more to renew, so both increased labor intensity, change inconveniently again, and the asbestos packing that changes can cause to a certain degree pollution to environment.
Summary of the invention
The purpose of this utility model will provide a kind of novel leakage proof centrifugal pump exactly, and it can overcome the deficiencies in the prior art, adopts " Y " type Cowhells seal ring to make sealing material, reaches the purpose of centrifugal pump leakage proof, and replacing is convenient, sealing effect is reliable.
The purpose of this utility model is achieved in that a kind of novel leakage proof centrifugal pump, comprise sleeve nut 1, porose end cap 2, bearing 3, bearing interstage sleeve 4, axle sleeve first 5, Gland 6, bearing support 7, suction casing 8, seal ring 9, impeller 10, stage casing 11, stator 12, stator cover 13, Spit Section 14, balance ring set 15, Balance disc 16, stuffing box body 17, axle sleeve second 18, axle 19, round nut 20 and atresia end cap 21, be provided with " Y " type Cowhells seal ring 22 in the groove of centrifugal pump two ends stuffing box body 17, the internal diameter of " Y " type Cowhells seal ring 22 is identical with axle 19 diameters, axle 19 passes " Y " type Cowhells seal ring 22, and by axle sleeve first 5 and axle sleeve second 18 " Y " type Cowhells seal ring 22 is fixed.
The utility model is because employing is provided with the structure of " Y " type Cowhells seal ring in the groove of the stuffing box body of centrifugal pump, so axle and " Y " type Cowhells seal ring are closely cooperated, centrifugal pump the seepage phenomenon can not occur when guaranteeing use.The utility model also is simple in structure and convenient in use.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Wherein, Fig. 1 double as Figure of abstract.
Among the figure: 1, sleeve nut, 2, porose end cap, 3, bearing, 4, the bearing interstage sleeve, 5, axle sleeve first, 6, Gland, 7, bearing support, 8, suction casing, 9, seal ring, 10, impeller, 11, the stage casing, 12, stator, 13, stator cover, 14, the Spit Section, 15, the balance ring set, 16, Balance disc, 17, stuffing box body, 18, axle sleeve second, 19, axle, 20, round nut, 21, the atresia end cap, 22, " Y " type Cowhells seal ring.
Embodiment
As shown in Figure 1, a kind of novel leakage proof centrifugal pump, comprise sleeve nut 1, porose end cap 2, bearing 3, bearing interstage sleeve 4, axle sleeve first 5, Gland 6, bearing support 7, suction casing 8, seal ring 9, impeller 10, stage casing 11, stator 12, stator cover 13, Spit Section 14, balance ring set 15, Balance disc 16, stuffing box body 17, axle sleeve second 18, axle 19, round nut 20 and atresia end cap 21, be provided with " Y " type Cowhells seal ring 22 in the groove of centrifugal pump two ends stuffing box body 17, the internal diameter of " Y " type Cowhells seal ring 22 is identical with axle 19 diameters, axle 19 passes " Y " type Cowhells seal ring 22, and by axle sleeve first 5 and axle sleeve second 18 " Y " type Cowhells seal ring 22 is fixed.
During assembling, centrifugal pump two ends stuffing box body 17 is pulled down, " Y " type Cowhells seal ring 22 is packed in the groove of stuffing box body 17, again axle 19 is penetrated Y " type Cowhells seal ring 22; with axle sleeve first 5 and axle sleeve second 18 " Y " type Cowhells seal ring 22 is compressed sealing, use sleeve nut 1 and round nut 20 that porose end cap 2 is fixedlyed connected with axle 19 with atresia end cap 21 at last and get final product.
