Description

Technical Field

[0001] The utility model relates to the technical field of shaft seats, in particular to a shaft seat with a new type of outer-cladding water-cooling structure. Background Art

[0002] During the operation of the sludge pump, due to the viscosity and high friction of the sludge, a large amount of heat will be generated. If this heat cannot be dissipated in time, the temperatures of components such as the pump body, shaft and bearing will rise. When the temperature rises to a certain level, the performance of these components will be affected, such as the thermal expansion of materials, the failure of lubricating oil, etc., thereby reducing the working efficiency and service life of the sludge pump.

[0003] By setting a cooling water jacket or cooling water pipe outside the sludge pump, using the flow of cooling water to take away the heat generated by the pump body and shaft, or by setting a lubricating oil chamber inside the pump, using the circulation of lubricating oil to take away the heat, but attention needs to be paid to the selection and replacement cycle of the lubricating oil.

[0004] However, when the above cooling methods are used, the structural settings are complex, and the later maintenance cost and usage cost are high. Content of the Utility Model

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figures 1 - 3 A new type of shaft seat with an external water-cooling structure includes a shaft seat body 1, which is installed on a pump body 9. The shaft body 11 of the pump body 9 is installed in the center of the shaft seat body 1. A cooling bin 2 is provided at the bottom of the shaft seat body 1. The top of the cooling bin 2 is open. A water inlet 3 and a water outlet 4 are respectively provided on both sides of the cooling bin 2. The water inlet 3 and the water outlet 4 are respectively used for the entry and discharge of coolant. The coolant contacts the bottom of the shaft seat through the opening of the cooling bin 2.

[0020] During the normal operation of the shaft seat body 1, coolant can be injected into the cooling chamber 2 through the water inlet 3. The coolant is allowed to directly contact the shaft seat body 1 and then discharged through the water outlet 4 to achieve heat dissipation of the shaft seat. Compared with the external cooling system or the built-in lubricating oil system in the prior art, the present device has a simple structure, and the initial production and later maintenance costs are effectively reduced.

[0021] In this embodiment, the bottom of the cooling bin 2 is designed to be open, and a connecting plate 5 is installed on the outer periphery of the bottom of the cooling bin 2. The connecting plate 5 is detachably installed with a sealing plate 6 by bolts. The sealing plate 6 is abutted against the bottom of the connecting plate 5 through a sealing gasket. Through the design of the sealing plate 6, the sealing plate 6 can be directly removed to clean the inside of the cooling bin 2, thereby avoiding the formation of scale on the outside of the shaft seat body 1 due to long-term use, which affects the heat dissipation effect.

[0022] In this embodiment, embedding grooves 7 are provided above the front and rear sides of the cooling bin 2. The embedding grooves 7 are semi-elliptical and are concentrically arranged with the shaft seat body 1. The cooling bin 2 is arranged on the outside of the shaft seat body 1 through two embedding grooves 7. This design method is conducive to sufficient contact between the coolant and the shaft seat body 1.

[0023] In this embodiment, the inner wall length of the embedded groove 7 is less than half of the outer circumference of the shaft seat body 1, and mounting parts 8 are installed on both sides of the shaft seat body 1. The mounting parts 8 can be installed on the support seat 10 by bolts, and the cooling chamber 2 is integrally formed with the shaft seat body 1.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
