Description
Technical Field
[0001] The utility model relates to the technical field of water pump mouth rings, in particular to an energy-saving mouth ring structure for a turbid water pump. Background Art
[0002] The mouth ring of a water pump refers to an annular metal ring installed between the impeller and the pump body. Its function is to prevent the conveying medium from flowing from the high-pressure area to the low-pressure area, and to play a sealing role. It also plays a wear-resistant role, avoiding direct contact between the impeller and the pump body and damaging it, and protecting the impeller. There is a gap between the mouth ring and the impeller and the pump body. The size of the gap affects the operating parameters of the pump, including flow and efficiency. During the operation of the pump, due to natural wear, solid particles in the medium, impeller shaking, etc., the gap will gradually increase and may even fail to play a sealing role.
[0003] Especially in turbid water, due to the high impurity content, the ring wears very quickly, and the parameters will drop significantly and the energy consumption per ton of water will increase significantly in a short period of time. Frequent replacement of the ring is required to ensure the efficient operation of the water pump. Therefore, the traditional water pump ring has the following main shortcomings:
[0004] (1) The traditional mouth ring structure is used for turbid water medium transportation, which can easily lead to the problem of parameter decrease and increased energy consumption;
[0005] (2) When repairing or replacing worn rings, the traditional method is: if the ring is slightly worn, the worn part is welded or thermally sprayed before machining; if the ring is severely worn, a new ring is reprocessed. These methods are time-consuming and labor-intensive, with high maintenance costs. In addition, during the period before the ring is maintained and replaced, the increase in electricity costs caused by increased energy consumption is far greater than the maintenance cost. Summary of the invention
[0006] The purpose of the utility model is to solve the above-mentioned deficiencies and provide an energy-saving mouth ring structure for a turbid water pump, which has better sealing durability and is convenient and quick to replace, and can keep the internal leakage of the turbid water pump at a low level for a long time, reduce maintenance costs and maintain efficient operation.

The radial dimension of the sealing gap 2 12 is smaller than the radial dimension of the sealing gap 11, thereby preventing particles larger than the sealing gap size from entering the sealing gap.
[0010] Furthermore, the ring base 5 is made of metal material, and the outer ring 4 and the inner ring 6 are made of elastomeric material, which has a longer service life. The elastomer also has a certain compensation effect, the sealing gap can be smaller, and the sealing effect is better.

[0018] (4) The radial dimension of the sealing gap of the utility model is smaller than the radial dimension of the sealing gap, which can prevent particles larger than the sealing gap from entering the sealing gap. When the ring wears, the wear is located in the radial position of the ring, so that the ring base will basically not wear;
[0019] (5) In the structure of the utility model, the vulnerable parts of the mouth ring are only the outer mouth ring and the inner mouth ring, so when wear occurs, only the outer mouth ring and the inner mouth ring need to be replaced;

DETAILED DESCRIPTION
[0030] The utility model provides an energy-saving mouth ring structure for a turbid water pump, comprising a mouth ring 2, which is installed between a pump body 1 and an impeller 3. Figure 1 shown.
[0031] As attached Figure 2 To Attachment Figure 7 As shown, the mouth ring 2 includes an outer mouth ring 4, a mouth ring base 5, an inner mouth ring 6 and a mouth ring gland 7. The outer mouth ring 4 and the inner mouth ring 6 are both annular and are respectively installed on the outer circumference and inner circumference of the mouth ring base 5. The outer annular surface and the inner annular surface of the mouth ring base 5 are respectively provided with an outer annular recess 51 and an inner annular recess 53. The outer mouth ring 4 is provided with an outer annular protrusion 42, and the outer annular recess 51 is inserted through the outer annular protrusion 42. The inner mouth ring 6 is provided with an inner annular protrusion 62, and the inner annular recess 53 is inserted through the inner annular protrusion 62. The outer mouth ring 4, the mouth ring base 5, and the inner mouth ring 6 are installed with a mouth ring gland 7 at the bottom; the mouth ring base 5 is made of metal material, and the outer mouth ring 4 and the inner mouth ring 6 are made of elastomer material, which has a longer service life, and the elastomer also has a certain compensation effect, the sealing gap can be smaller, and the sealing effect is better.
[0032] Among them, threaded holes 1 52 are distributed along the circumferential direction on the bottom surface of the ring base 5, and corresponding threaded holes 2 71 are arranged on the ring gland 7. The ring gland 7 and the ring base 5 are connected as a whole through the threaded holes 1 52, the threaded holes 2 71 and the hexagon socket bolts. The ring gland 7 axially fixes the outer ring 4 and the inner ring 6, thereby avoiding axial movement. There are sealing gaps 2 12 between the outer ring 4 and the pump body 1 and between the inner ring 6 and the impeller 3. There are sealing gaps 11 between the upper part of the ring base 5 and the pump body 1 and the impeller 3. The radial dimension of the sealing gap 2 12 is smaller than the radial dimension of the sealing gap 11, thereby preventing particles larger than the sealing gap size from entering the sealing gap.
[0033] The mouth ring base 5 is a T-shaped structure in the longitudinal section composed of an upper base and a lower base. The upper base and the lower base are an integral structure. The outer mouth ring 4 and the inner mouth ring 6 are respectively installed on the outer circumference and inner circumference of the lower base; the outer annular recess 51 is arranged at the angle between the top of the outer annular surface of the lower base and the bottom surface of the upper base, and the inner annular recess 53 is arranged at the angle between the top of the inner annular surface of the lower base and the bottom surface of the upper base; the outer annular protrusion 42 is arranged on the inner circumference of the top of the outer mouth ring 4, and the inner annular protrusion 62 is arranged on the outer circumference of the top of the inner mouth ring 6.
[0034] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:
[0035] The turbid water pump mouth ring structure described in the utility model has a mouth ring 2 installed between the pump body 1 and the impeller 3. The mouth ring 2 is composed of an outer mouth ring 4, a mouth ring base 5, an inner mouth ring 6, and a mouth ring pressure cover 7. There are two annular recesses on the annular surface of the mouth ring base 5, namely an outer annular recess 51 and an inner annular recess 53. The outer mouth ring 4 has an outer annular protrusion 42, which is inserted into the outer annular recess 51 during assembly; the inner mouth ring 6 has an inner annular protrusion 62, which is inserted into the inner annular recess 53 during assembly, radially fixing the outer mouth ring 4 and the inner mouth ring 6 to avoid radial movement. There are several threaded holes on the annular surface of the mouth ring base 5, and the mouth ring pressure cover 7 also has several corresponding threaded holes, which are connected with hexagon socket bolts to axially fix the outer mouth ring 4 and the inner mouth ring 6 to avoid axial movement.
[0036] The outer ring 4 contacts the pump body 1, and the inner ring 6 contacts the impeller 3, and both have a certain sealing gap 12; there is a certain sealing gap 11 between the ring base 5 and the pump body 1 and the impeller 3; the sealing gap 12 is close to the high-pressure area, and the sealing gap 11 is close to the low-pressure area. A small amount of conveying medium enters the low-pressure area from the high-pressure area, first passing through the sealing gap 12, and then passing through the sealing gap 11; the radial dimension of the sealing gap 12 is smaller than the radial dimension of the sealing gap 11, which can prevent particles larger than the size of the sealing gap 12 from entering the sealing gap 11; when the ring is worn, the wear is located in the radial position of the ring, so the wear surfaces are the outer ring wear surface 41 and the inner ring wear surface 61, respectively, and the ring base 5 basically does not wear, and even if some wear occurs, it does not affect the use. In this structural arrangement, the vulnerable parts of the ring are only the outer ring 4 and the inner ring 6. When wear occurs, only the outer ring 4 and the inner ring 6 need to be replaced.
[0037] The steps of replacing the mouth ring of the utility model are: remove the mouth ring 2 → remove the inner hexagonal bolt → remove the mouth ring cover 7 → remove the worn outer mouth ring 4 and the inner mouth ring 6 → install the new outer mouth ring 4 and the inner mouth ring 6 → install the mouth ring cover 7 → tighten the inner hexagonal bolt → install the mouth ring 2, which shows that the replacement is very convenient and quick.
[0038] In the utility model, the mouth ring base 5 is a skeleton, which is made of metal material. The outer mouth ring 4 and the inner mouth ring 6 are used for wear and sealing, and are made of elastomeric materials, which have a certain elasticity. The wear resistance to natural wear, impeller shaking, particles in the medium, etc. is better than that of metal materials, and the service life is longer; and the elastomer also has a certain compensation effect, the sealing gap 12 can be smaller, and the sealing effect is better. The outer mouth ring 4 and the inner mouth ring 6 account for a smaller structure of the entire mouth ring 2, and the manufacturing accuracy and roughness requirements are much lower than those of traditional mouth rings. The manufacturing is more convenient and the cost is lower. It can be mass-produced as spare parts and replaced regularly. The utility model achieves lower maintenance costs to ensure that the turbid water pump always maintains efficient operation and saves energy and reduces consumption.
