What is a pump impeller and what is its use?<\/strong><\/h2>\n

The pump impeller is one of the rotating parts in all types of pumps that transfers energy from the pump motor to the used fluid. The propeller consists of a series of vanes that go out from its open entrance in the central part of the propeller or the eye of the propeller, and when it rotates, a force is created and it directs the desired fluid from the chamber to the place of discharge. Water pump hubs are located in the middle part of the propellers and are mounted on the main axis. The design and use of each propeller plays an important role in the size of the .ball<\/p>\n

In buildings with a large number of\u00a0 floors, when the water pressure decreases, the need \u00a0for\u00a0 a water becomes more.<\/p>\n

Also, in\u00a0 industry and\u00a0 agriculture, the\u00a0 water\u00a0 pump has\u00a0 high efficiency. The pump impeller\u00a0 is\u00a0 the most important part of the water pump, which is\u00a0 located\u00a0 in the\u00a0 inner\u00a0 part of the water\u00a0 supply pump. The\u00a0 impeller of\u00a0\u00a0 the\u00a0 water\u00a0 pump\u00a0 increases\u00a0 or decreases\u00a0 the\u00a0 pressure and\u00a0 flow of liquids according\u00a0 to\u00a0 the\u00a0 application of\u00a0 water\u00a0 supply \u00a0pumps.<\/p>\n

What are the types of water pump?<\/strong><\/h2>\n

There\u00a0 are\u00a0 different types of pump impellers, and each of them\u00a0 has its own special\u00a0 characteristics, and\u00a0 for\u00a0 this reason, each of\u00a0 them has a specific application. Impellers play a very\u00a0 important\u00a0 role\u00a0 in the perfor mance \u00a0of pumps, and for this\u00a0 reason, the size and\u00a0 type\u00a0 of impeller has a direct impact on\u00a0 determining the specifications and characteristics of\u00a0\u00a0 pumps.<\/p>\n

Types of pump propellers in\u00a0 terms of mechanical construction<\/strong><\/h3>\n

The pump impeller has 4 different types in terms of mechanical structure,including open impeller,semi-open impeller, shear\u00a0 impeller,and vortex pump impeller.<\/p>\n

Open pump impeller<\/strong><\/h4>\n

The open\u00a0 propeller has blades, that are\u00a0 free and uncovered \u00a0on both\u00a0 sides, and this\u00a0 makes\u00a0 them work weaker.it \u00a0is\u00a0 used in small\u00a0 and cheap pumps that are supposed to withstand\u00a0 low pressure. Unlike closed type impellers, these impellers can\u00a0\u00a0 also pump some solids. This type can be used in the sludge pump.<\/p>\n

closed pump impeller<\/strong><\/h4>\n

this type is closed on both sides and\u00a0 has\u00a0 the\u00a0 most\u00a0 strength among\u00a0 all\u00a0 types of pumps.<\/p>\n

These types of\u00a0 propellers have a more complex structure than other pumps, and\u00a0 hence they have a higher price. These impellers are one of the most famous types\u00a0 for use in large pumps that have the task of \u00a0transferring clean liquids.<\/p>\n

Because\u00a0 the\u00a0 impellers of\u00a0 this type are closed on both sides and\u00a0 there is a\u00a0 possibility of\u00a0 blocking the impeller,<\/p>\n

These cannot be\u00a0 used\u00a0 for\u00a0 pumping fluids with solid materials.<\/p>\n

Pump impeller half open<\/strong><\/h4>\n

In\u00a0 this\u00a0 type of\u00a0 propellers,one side of its blades has a protective plate\u00a0 that\u00a0 increases mechanical\u00a0 strength ,and\u00a0 the other side is open. In terms of function, this type of\u00a0 propeller\u00a0 can be considered\u00a0 between\u00a0 open and\u00a0 closed . these types of\u00a0 propellers are used\u00a0 in medium- sized pumps with a small amount of soft solids. For efficiency and\u00a0 better<\/p>\n

Performance,the distance between\u00a0 the\u00a0 impellers and\u00a0 the\u00a0 pump\u00a0 housing\u00a0 should\u00a0 be small.<\/p>\n

To prevent\u00a0 the\u00a0 propellers from blocking, the\u00a0 number\u00a0 of\u00a0 blades\u00a0 is small and\u00a0 their length\u00a0 is considered\u00a0 long.<\/p>\n

Vortex pump impeller<\/strong><\/h4>\n

Unlike the previous 3 models\u00a0 mentioned, the impeller of\u00a0 the vortex pump is not channeled.<\/p>\n

The appearance of the impeller is similar to the semi-open types, but the\u00a0 space between the blades is more, and they have different\u00a0 functions. This type of\u00a0 propeller is suitable for contaminated liquids or some suspended solids, because when it\u00a0 draws in the liquid, it creates a vacuum-like vortex, and\u00a0 the \u00a0solids move away from the blade and do not\u00a0 damage the internal parts. This propeller model does not have a high efficiency, but\u00a0 it has\u00a0 advantages such as a very low probability of clogging and\u00a0 transfer of solid materials in some cases\u00a0 has\u00a0 made them\u00a0 popular and therefore they are used a lot.<\/p>\n

Shear pump impeller<\/strong><\/h4>\n

A shear\u00a0 impeller like a vortex impeller\u00a0 is designed for use or\u00a0 contaminated\u00a0 liquids with\u00a0 solid\u00a0 materials and they\u00a0 differ in the blade. The\u00a0 cutting impeller is very\u00a0 sharp and\u00a0 cuts\u00a0 and destroys\u00a0 the\u00a0 solids before entering the pump. The\u00a0 efficiency of this impeller is not as high as that of\u00a0 a vortex, but\u00a0 it is\u00a0 a suitable option for sewage and substances\u00a0 that\u00a0 cause\u00a0 pipe\u00a0 blockage.<\/p>\n

Types of pump impellers in terms of fluid flow<\/strong><\/h3>\n

Radial flow<\/strong><\/h4>\n

In general, the fluid\u00a0 enters the\u00a0 impeller in the\u00a0 axial direction and\u00a0 leaves the impeller in the radial direction.<\/p>\n

In these types of\u00a0 propellers, the fluid moves\u00a0 along the length of the blade due to centrifugal force, and the kinetic energy of\u00a0 the\u00a0 fluid increases.This type is used in places where low flow rate and\u00a0 high\u00a0 head\u00a0 are\u00a0 required. Propellers used in\u00a0 petrochemicals are often of this type.<\/p>\n

Axial flow <\/strong><\/h4>\n

Centrifugal force does not play a\u00a0 role in producing\u00a0 pressure for\u00a0 this type of propeller . the flow enters in the direction of\u00a0 the axis and\u00a0 leaves\u00a0 it in the same direction. When high flow rate\u00a0 and\u00a0 low head\u00a0 are\u00a0 needed , this type of propeller is used.<\/p>\n

Radial, axial flow<\/strong><\/h4>\n

The\u00a0 flow enters in the direction of the axis and makes an angle with the axis and exits from it. In fact, these types of propellers have a state between\u00a0 radial flow propeller\u00a0 and\u00a0 axial\u00a0 flow propeller.<\/p>\n

Types of propellers in terms of fluid entry status<\/strong><\/h3>\n

Single suction<\/strong><\/p>\n

In this type of impeller, there\u00a0 is an\u00a0 opening on only one side of\u00a0 the impeller and the fluid\u00a0 enters the impeller from that part.<\/p>\n

Double suction<\/strong><\/h4>\n

In this type of impellers, there are\u00a0 suction openings on both sides of the impeller, and the fluid enters the pump from each of the openings. The water capacity of this type of pump is 2\u00a0 times the water capacity of a one-way suction pump.<\/p>\n

The material of the pump impeller <\/strong><\/h2>\n

Water pump impellers are\u00a0 made of\u00a0 different materials. Including different alloys such as\u00a0 bronze, cast iron,steel, brass, fiberglass, etc.The important thing is that\u00a0 the impeller is compatible with the pump itself.<\/p>\n

?What are the advantages of bronze impeller pump<\/strong><\/h3>\n

The advantages of the pump,s\u00a0 bronze impeller include the following:<\/p>\n

    \n
  1. high performance capability.<\/li>\n
  2. it has a low wear rate.<\/li>\n
  3. its axis wears less.<\/li>\n
  4. it shows high resistance to pressure.<\/li>\n
  5. it can be analyzed with water or processed liquids such as oil or grease.<\/li>\n<\/ol>\n

    What are the symptoms of water pump propeller failure?<\/strong><\/h2>\n

    Jamming the water pump\u00a0 means not moving the impeller of the pumps and\u00a0 getting them\u00a0 stuck. Also ,the jamming of the home water pump bearing can also cause it to jam.\u00a0 If this problem is not solved quickly, the force that\u00a0 enters\u00a0 the coil and does not come out, causes a lot of pressure to be applied to the engine and may burn it. Water retention can happen for a\u00a0 number of reasons, including:<\/p>\n

      \n
    • Wear parts: <\/strong>One of\u00a0 the problems that exist\u00a0 when using water is water solutes, which after some time causes them to precipitate. Deposits on the impeller limit its movements and disrupt its circulation, and if the deposits are not\u00a0 removed,the pump may get stuck.<\/li>\n
    • Rusting of pump parts :<\/strong><\/li>\n<\/ul>\n

      The parts of these water pumps are metal, although stainless metals are used to make them, but some times it has been observed that\u00a0 these metals are\u00a0 rusted. Rust fills the space\u00a0 between the shell and the propeller and prevents it\u00a0 from moving.<\/p>\n

        \n
      • Failure of\u00a0 the\u00a0 water pump bearing\u00a0 of the\u00a0 machine and\u00a0 jamming it:<\/strong><\/li>\n<\/ul>\n

        The failure of the bearing quickly affects the performance of the pump, and in case of failure, you must change it quickly .<\/p>\n

        The presence of sand particles\u00a0 in the fluid can also disrupt\u00a0 the rotation of the motor and the pump impeller.<\/p>\n

        Changing the impeller, venting the pump, changing the bearings, changing the felt bowl, etc. can prevent the pump from jamming. To prevent the water pump from jamming, it is better to service it periodically.
