Description

Technical Field

[0001] The utility model belongs to the technical field of cast iron pumps, and in particular relates to a cast iron pump casing structure. Background Art

[0002] A water pump is a machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increases the liquid energy, and can pump the liquid from a low place to a high place or a distant place. Cast iron pump is a type of water pump. Most pumps that use cast iron to make the pump casing are called cast iron pumps.

[0003] The cast iron pump casing structure currently on the market has the following problems when in use:

[0004] 1. The traditional cast iron pump casing structure is usually put into the liquid together with the cast iron pump for use. Most of the casings can only cover the outside of the pump body. However, due to the weight of the cast iron pump and the casing, they will sink to the bottom of the liquid when in use. There are usually foreign objects such as dirt or sand at the bottom of the liquid. As a result, when the cast iron pump pumps the liquid into the interior, it is easy to suck the dirt or sand foreign objects at the bottom of the liquid into the pump body, which is less practical when in use;

[0005] 2. The traditional cast iron pump casing structure usually installs the main parts of the cast iron pump, such as the pump body, impeller, pump shaft, bracket, coupling, etc., inside the casing during use, and uses the external casing of the cast iron pump for protection. When it is hit, most of the impacts are directly on the surface of the casing, but most of the casing and the cast iron pump are an integrated structure, which means that the entire casing needs to be replaced after the casing is damaged by a collision. The protection of the casing is low, and the protection is insufficient during use. Utility Model Content

[0006] The utility model aims to provide a cast iron pump casing structure to solve the technical problems raised in the background technology.

[0028] like Figure 1-4 As shown, a cast iron pump casing structure of the utility model comprises a main body 1, a base 2 is installed at the bottom of the main body 1, a bottom plate 6 is installed at the bottom of the base 2, a fixing plate 7 is provided at the top of the bottom plate 6, a first bolt 10 is passed through the interior of the fixing plate 7, and the fixing plate 7 can be fixed to the bottom plate 6 by the first bolt 10, and the floating ring 9 can be removed by unscrewing the first bolt 10 when the floating ring 9 is not needed or needs to be replaced, which is more convenient when used, the external thread of the first bolt 10 is connected to the bottom plate 6, the top of the fixing plate 7 is fixedly connected to the supporting column 8, and the floating ring 9 is installed on the top of the supporting column 8, and through the provided floating ring 9, when the cast iron pump machine casing is put into the liquid for use, the floating ring 9 is subjected to a large buoyancy, and the floating ring 9 will be suspended in the liquid, which makes the cast iron pump and the casing also be pulled and suspended by the floating ring 9 to avoid contact with the bottom liquid, and it is not easy to suck foreign matter such as dirt or mud in the bottom liquid into the interior of the cast iron pump during operation, and the practicality is better when used.

[0029] A first protective shell 11 is provided on the outside of the main body 1, and a second protective shell 12 is provided on the outside of the main body 1. The surface rotation axis of the first protective shell 11 is connected to the second protective shell 12, and a buffer pad 13 is installed inside the first protective shell 11 and the second protective shell 12. The first protective shell 11 is provided, and the second protective shell 12 is cooperated to cover the four sides of the main body 1. When a collision occurs, the first protective shell 11 or the second protective shell 12 receives the impact, and the buffer pad 13 inside it is used for buffering, thereby reducing the damage to the main body 1 caused by the collision, avoiding damage to the main body 1 during a collision, and providing better protection when used.

[0030] A clamp seat 16 is installed on the surface of the first protective shell 11, and the internal thread of the clamp seat 16 is connected to the butterfly bolt 15. The surface of the second protective shell 12 is welded with a threaded strip 14. Through the provided threaded strip 14, the threaded strip 14 can be inserted into the interior of the clamp seat 16, and the butterfly bolt 15 is turned to drive the threaded strip 14 to move, so that the first protective shell 11 and the second protective shell 12 are tightened and pressed together, so that the first protective shell 11 and the second protective shell 12 are fixed to the outside of the main body 1, which is more convenient to fix.

[0031] The top of the main body 1 is fixedly connected to the threaded seat 3, and the internal thread of the threaded seat 3 is connected to the hanging ring 4. Through the provided hanging ring 4, the main body 1 can be effectively taken, which is more convenient to use.

[0032] A flange 5 is welded on the surface of the main body 1, and a mounting hole is provided inside the flange 5. Through the flange 5, it is more convenient to connect with the pipeline, and it is more convenient to connect the pipeline.

[0033] The surface of the main body 1 is welded with reinforcing ribs 17, and the reinforcing ribs 17 are distributed in a ring shape. The strength of the main body 1 can be effectively improved by providing the reinforcing ribs 17, and the strength is higher during use.

[0034] The working principle of the cast iron pump housing structure: when the cast iron pump housing structure is applied, the first protective shell 11 and the second protective shell 12 outside the main body 1 are connected together by a rotating shaft, and the first protective shell 11 and the second protective shell 12 are installed with a buffer pad 13 inside. The first protective shell 11 and the second protective shell 12 cover the main body 1 on all sides. When a collision occurs, the first protective shell 11 or the second protective shell 12 receives the impact to avoid hitting the surface of the main body 1. The buffer pad 13 is used for buffering, reducing the impact force transmitted to the main body 1 and reducing the damage to the main body 1 caused by the collision. The protection is better when used. The bottom of the base 2 at the bottom of the main body 1 is installed with a bottom plate 6, and the fixing plate 7 at the top of the bottom plate 6 passes through the first bolt 10, which can be The fixing plate 7 is fixed to the bottom plate 6 by the first bolt 10, and a float 9 is installed on the top of the support column 8 on the top of the fixing plate 7. When the cast iron pump machine housing is placed in liquid for use, the float 9 is subjected to a large buoyancy and will be suspended in the liquid. The buoyancy is greater than or equal to the overall weight, so that the float 9 will also pull the cast iron pump and the housing to suspend. At this time, the cast iron pump does not contact the liquid at the bottom, and will draw liquid at the upper position during operation, so it is not easy to suck foreign matter such as dirt or mud at the bottom of the liquid into the cast iron pump. The practicality is better when used. When the float 9 is not needed or needs to be replaced, the first bolt 10 can be unscrewed to remove the float 9 together with the fixing plate 7 and the support column 8, which is more convenient to use.
