Abstract
The energy-saving single-stage double-suction axially split pump with the reinforcing rib rotating body type bearing body comprises a pump body, the bearing body, a bearing, reinforcing ribs, a pump cover, a sealing ring, an impeller and a pump shaft, wherein the bearing supports the rotating pump shaft; the side surfaces of the pump body and the pump cover are connected with a rotating body type bearing body through fasteners, and reinforcing ribs are distributed on the outer edge of the bearing body. Because the rotary body type bearing body is fixedly connected with the side surfaces of the pump body and the pump cover, the vibration of the water pump during working is greatly reduced, the noise is reduced, the service life of the water pump is prolonged, and the mechanical efficiency of the water pump is improved. The utility model discloses simple structure has reduced the vibration of the pump body, and the noise of making an uproar falls, easily casting, the processing of being convenient for, the appearance is pleasing to the eye, reduce cost.
Description
Technical Field
The utility model relates to an energy-conserving single-stage double suction split pump, especially a take energy-conserving single-stage double suction split pump of strengthening rib rotator formula bearing body.
Background
The energy-saving single-stage double-suction split pump is used for conveying water and slightly corrosive liquid in occasions such as steel mills, power plants, chemical industry, oil fields, heating and the like, and structurally comprises a pump body, a bearing body, a pump shaft, an impeller and a pump cover. However, in the current energy-saving single-stage double-suction axially split pump, two structures are available for connecting the bearing body and the pump body. One is that two ears of the cantilever are cast on the left and right sides of the pump body, an inner hole capable of supporting a bearing body is bored on the ears, and the bearing body is embedded into the inner hole to enable the bearing to support the pump shaft to rotate (see figure 1); the other is that two cantilever beams are cast at the left side and the right side of the pump body, a bearing body with a connecting boss is connected to the side of the cantilever beam, and the bearing supports the pump shaft to rotate (see attached figure 2). As is known, the structure of horizontal middle opening pump, radial load are very big, and cantilever beam formula support bearing body structure can cause the water pump great vibration can appear in service, and big vibration can reduce the life of water pump, influences water pump mechanical efficiency, and the noise is high, and the environment is not pleasing to the eye. In addition, the water pump is inconvenient to cast and process, and the production cost of the water pump is increased. Therefore, it is necessary to design a new structure to replace the above-mentioned structure of the cantilever beam type support bearing body to overcome the disadvantages of the prior art.
Disclosure of Invention
In order to solve the defects of the prior art, the utility model aims at providing a take energy-conserving single-stage double suction split pump of strengthening rib rotating body formula bearing body that the vibration is little, the noise is low to prolong the life of water pump, improved water pump mechanical efficiency.
Realize the utility model discloses a technical scheme that the purpose adopted is: the energy-saving single-stage double-suction axially split pump with the reinforcing rib rotating body type bearing body comprises a pump body, the bearing body, a bearing, reinforcing ribs, a pump cover, a sealing ring, an impeller and a pump shaft, wherein the bearing supports the rotating pump shaft; the pump is characterized in that the side surfaces of the pump body and the pump cover are connected with a rotating body type bearing body through a fastening piece, and reinforcing ribs are distributed on the outer edge of the bearing body.
Compared with the prior art, the utility model the advantage be:
1. because the side fastening connection of rotator formula bearing body and pump body, pump cover compares with prior art firstly and has removed the cantilever beam, secondly has shortened the length of pump shaft, greatly reduced the during operation vibration of water pump, the noise diminishes, has prolonged the life of water pump, has improved water pump mechanical efficiency, and operational environment becomes more beautiful.
2. The reinforcing ribs are additionally arranged on the outer edge of the bearing body, so that the supporting strength of the bearing body is further enhanced, the vibration of the pump body is reduced, and the noise reduction and service life are prolonged.
3. The bearing body is a rotating body, a connecting boss at the outer edge is removed, the pump body is not provided with a cantilever beam, the structure is simple, the casting is easy, the processing is convenient, the appearance is attractive, and the cost is reduced.

FIG. 2 is a cross-sectional block diagram of another single-stage, double suction, split pump of the prior art.
Fig. 3 is a sectional structure view of the energy-saving single-stage double-suction axially split pump with the reinforcing rib rotary bearing body of the utility model.
Detailed Description
In the attached figure 3, the utility model relates to an energy-saving single-stage double-suction axially split pump with a reinforced rib rotator type bearing body, which comprises a pump body, a bearing, a reinforced rib, a pump cover, a sealing ring, an impeller and a pump shaft, wherein the bearing 3 supports a rotary pump shaft 9, the middle part of the pump shaft 9 is fixed with the impeller 8, the impeller 8 is connected with the pump body 1 through the sealing ring 7 in a matching way, and the pump cover 6 is connected on the pump body 1; the pump is characterized in that the side surfaces of the pump body 1 and the pump cover 6 are connected with a rotating body type bearing body 2 through a fastening piece. Because the side fastening connection of rotator formula bearing body and pump body, pump cover compares with prior art firstly and has removed the cantilever beam, secondly has shortened the length of pump shaft, greatly reduced the during operation vibration of water pump, the noise diminishes, has prolonged the life of water pump, has improved water pump mechanical efficiency, and operational environment becomes more beautiful. Reinforcing ribs 5 are distributed on the outer edge of the bearing body 2; the reinforcing ribs can further enhance the supporting strength of the bearing body, reduce the vibration of the pump body and reduce noise and prolong the service life. The bearing body is a rotating body, a connecting boss at the outer edge is removed, the pump body is not provided with a cantilever beam, the structure is simple, the casting is easy, the processing is convenient, the appearance is attractive, and the cost is reduced.
