Abstract
A shell structure of a furnace water circulating pump. The furnace water circulating pump shell comprises an inner layer and an outer layer, the inner layer comprises a base layer and a corrosion-resistant layer, the outer connecting layer and a supporting layer are connected together through reinforcing ribs, and the reinforcing ribs are in a honeycomb regular hexagon shape. The shell structure of the boiler water circulation pump is characterized in that the shell is provided with an inner layer structure and an outer layer structure, the inner layer structure and the outer layer structure are connected through the reinforcing ribs, the shell has higher strength and pressure resistance, but the weight is increased by a small amount, and in addition, the reinforcing ribs are arranged into a honeycomb regular hexagon, so that the structure is more stable, the larger strength can be achieved by using smaller mass, the stress is balanced, no weak position exists, and the pressure bearing is larger.
Description
Technical Field
The invention relates to the technical field of circulating pumps, in particular to a shell structure of a furnace water circulating pump.
Background
The boiler water circulating pump is a large-flow, low-lift single-stage centrifugal pump which is arranged in a boiler evaporation system and bears high temperature and high pressure to make working media perform forced flow, and structurally comprises a pump shell, pump blades, a bearing and a heat insulator. Boiler water circulation pumps are commonly used in start-up systems for forced circulation drum boilers and once-through boilers. A pump housing and an impeller. The pump casing is a hemispherical structure, and is characterized by that its wall thickness is small, its correspondent thermal stress is small, and the pump blade is a high-specific revolution centrifugal type, close to mixed flow type single-stage centrifugal pump, and the outlet of pump blade is equipped with pump blade to make partial kinetic energy be converted into pressure energy.
Wherein the pump case is exactly used for circulating furnace water, because furnace water has higher temperature, so the casing of general material all lacks in withstand voltage aspect, contain a lot of impurities in addition in the furnace water, such as metal particle, active ion and material such as acid-base, therefore pump case inner wall is corroded very easily, the casing will become thin for a long time, and then be intolerant to high pressure, present technique is many can be through increasing casing thickness increase life, but so will increase the material of use, increase the quality of casing, from the other side increase the cost, and also must not increase its withstand voltage ability yet.
Disclosure of Invention
Aiming at the problems in the related art, the invention provides a shell structure of a furnace water circulating pump, which has the advantages that the shell has higher strength and pressure resistance through an inner layer structure and an outer layer structure, and the two layers are connected through reinforcing ribs, but the weight is increased less, in addition, the reinforcing ribs are arranged into a honeycomb regular hexagon, so the structure is more stable, the larger strength can be achieved by using smaller mass, the stress is balanced, no weak position exists, and the pressure bearing is larger.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a furnace water circulation pump shell structure, which adopts the following scheme:
the furnace water circulating pump shell comprises an inner layer and an outer layer, the inner layer comprises a base layer and a corrosion-resistant layer, the outer connecting layer and a supporting layer are connected together through reinforcing ribs, and the reinforcing ribs are in a honeycomb regular hexagon shape.
Furthermore, the side length of the regular hexagon is 1-1.5cm, the height of the regular hexagon is 0.5cm, and the thickness of each side length is 1 mm.
The invention has the beneficial effects that:
the shell structure of the boiler water circulation pump is characterized in that the shell is provided with an inner layer structure and an outer layer structure, the inner layer structure and the outer layer structure are connected through the reinforcing ribs, the shell has higher strength and pressure resistance, but the weight is increased by a small amount, and in addition, the reinforcing ribs are arranged into a honeycomb regular hexagon, so that the structure is more stable, the larger strength can be achieved by using smaller mass, the stress is balanced, no weak position exists, and the pressure bearing is larger.

FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
According to an embodiment of the invention, a pump shell structure of boiler water circulation is provided, and the scheme is as follows:
referring to fig. 1, the furnace water circulating pump shell comprises an inner layer and an outer layer, the inner layer 1 comprises a base layer and a corrosion-resistant layer, the outer layer 2 comprises a connecting layer and a supporting layer, the base layer of the inner layer 1 and the connecting layer of the outer layer 2 are connected together through a reinforcing rib 3, the reinforcing rib 3 is a honeycomb-shaped regular hexagon, the side length of the regular hexagon is 1-1.5cm, the height of the regular hexagon is 0.5cm, and the thickness of each side length is 1 mm.
The boiler water circulation pump shell structure is through inside and outside two-layer structure, and connect through the strengthening rib between two-layer, make the casing have higher intensity and compressive capacity, but increase less weight, intensity and compressive resistance are higher under the same quality, the quality is littleer under the same intensity and compressive resistance, cellular regular hexagon is set to in addition the strengthening rib, so the structure is more stable, regular hexagon length of side 1-1.5cm, high 0.5cm, the thickness of every length of side is 1mm, so available less quality reaches great intensity, and the atress is balanced, there is not weak position, the pressure-bearing is bigger.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
