Abstract
A combined water-cooling bearing seat is characterized in that a bearing is arranged on a pump shaft, and a water-cooling bearing body is arranged on an outer ring of the bearing in a transition fit manner; a bearing gland is arranged on the right side of the water-cooled bearing body, the water-cooled gland is fixed on the left side of the bearing body by a bolt, and a small sealing ring and a large sealing ring are arranged on the contact surface of the water-cooled gland and the water-cooled bearing body; the outer edge of the water-cooling bearing body is provided with a water inlet communicated with a cold water pipe and a water outlet communicated with a drain pipe, a water circulation groove is arranged in the water-cooling bearing body, and the water inlet and the water outlet are communicated with the water circulation groove. Because the water-cooling bearing body is internally provided with the water circulation groove which is communicated with the water inlet communicated with the cold water pipe and the water outlet communicated with the water discharge pipe, the bearing can be effectively cooled by water circulation, and the service life of the bearing is prevented from being influenced by overhigh temperature of the bearing. The combined water-cooling bearing seat is simple in structure, easy to cast, convenient to process and stable and reliable in cooling effect, and improves the mechanical efficiency of the water pump.
Description
Technical Field
The utility model relates to a water pump bearing frame technical field especially relates to a modular water-cooling bearing frame.
Background
The bearing used in various industries is an important part in the modern mechanical equipment, and the main function of the bearing is to support a mechanical rotating body, reduce the friction coefficient in the motion process of the mechanical rotating body and ensure the rotation precision of the mechanical rotating body. At present, multistage centrifugal water pump has been widely used in steel mill, power plant, heating equipment, and its application occasion mostly is the operation under high temperature high pressure, and gaseous temperature can be conducted to the bearing frame through the casing, leads to the bearing again. The bearing can lead to the bearing to seriously wear under high temperature and high pressure long-term operation, can reduce the life-span of bearing to bring the potential safety hazard, lead to the bearing locking to shut down even, influence the production efficiency of whole production line.
Disclosure of Invention
In order to solve the defects of the prior art, the utility model aims at providing a combined water-cooling bearing seat, thereby solving the problem that the bearing can reduce the service life of the bearing when operating at high temperature for a long time, thereby bringing about potential safety hazards.
Realize the utility model discloses a technical scheme that the purpose adopted is: a combined water-cooling bearing seat comprises a water-cooling gland, a sealing ring, a water-cooling bearing body, a water inlet, a bearing gland, a bearing, a water outlet and a pump shaft; the pump shaft is provided with a bearing, and a water-cooled bearing body is arranged on the outer ring of the bearing in a transition fit manner; a bearing gland is arranged on the right side of the water-cooled bearing body, the water-cooled gland is fixed on the left side of the bearing body by a bolt, and a small sealing ring and a large sealing ring are arranged on the contact surface of the water-cooled gland and the water-cooled bearing body; the outer edge of the water-cooling bearing body is provided with a water inlet communicated with a cold water pipe and a water outlet communicated with a drain pipe, a water circulation groove is arranged in the water-cooling bearing body, and the water inlet and the water outlet are communicated with the water circulation groove.
The utility model has the advantages that: because the water-cooling bearing body is internally provided with the water circulation groove which is communicated with the water inlet communicated with the cold water pipe and the water outlet communicated with the water discharge pipe, the water circulation cooling bearing can be effectively cooled, and the service life of the bearing is prevented from being influenced by overhigh temperature. The combined water-cooling bearing seat is light in weight, small in size, free of leakage, attractive in appearance, simple in structure, easy to cast, convenient to process and disassemble, stable and reliable in cooling effect, relatively small in friction coefficient of the bearing, and capable of improving the mechanical efficiency of the water pump.

Detailed Description
In the attached drawings, the utility model relates to a combined water-cooling bearing seat, which comprises a water-cooling gland, a sealing ring, a water-cooling bearing body, a water inlet, a bearing gland, a bearing, a water outlet and a pump shaft; the pump shaft 10 is provided with a bearing 7, and a water-cooled bearing body 4 is arranged in transition fit with the outer ring of the bearing 7; a bearing gland 6 is arranged on the right side of the water-cooled bearing body 4, a water-cooled gland 1 is fixed on the left side of the bearing body 4 by bolts, a small sealing ring 2 and a large sealing ring 3 are arranged on the contact surface of the water-cooled gland 1 and the water-cooled bearing body 4, and the two sealing rings are sealed to prevent water in the water circulation tank from leaking laterally; the outer edge of the water-cooling bearing body 4 is provided with a water inlet 5 communicated with a cold water pipe and a water outlet 8 communicated with a drain pipe, a water circulation groove 9 is arranged in the water-cooling bearing body 4, and the water inlet 5 and the water outlet 8 are communicated with the water circulation groove 9. Because the water-cooling bearing body is internally provided with the water circulation groove which is communicated with the water inlet communicated with the cold water pipe and the water outlet communicated with the water discharge pipe, the water circulation cooling bearing can be effectively cooled, and the service life of the bearing is prevented from being influenced by overhigh temperature. The combined water-cooling bearing seat is light in weight, small in size, free of leakage, attractive in appearance, simple in structure, easy to cast, convenient to process and disassemble, stable and reliable in cooling effect, relatively small in friction coefficient of the bearing, and capable of improving the mechanical efficiency of the water pump.
