Slurry Pump Parts and Manufacturing Process of Slurry Pump

First, we need to know what the slurry pump accessories including;
         1, horizontal slurry pump parts can be divided into: slurry flow components (ie, part of the slurry in contact with the liquid), slurry pump bracket portion (also referred to as suspension), slurry base slurry pump and pump cover.
         Wherein the slurry carriage parts: the bracket body (suspension) is made of gray iron, are non-wearing parts, technology not ask for much, there are some accessories using common parts, such as bearings, screws, bolts, oil block, Griphook, oil immersion, belts, pulleys, couplings, flanges, gaskets, O-rings, mechanical seals, packing, glib, etc., generally do not need to produce a slurry pump manufacturers themselves.
         Slurry base generally just follow the slurry pump equipped with power motors in accordance with drawings for casting iron welding can be, either.



 Slurry pump slurry pump cover generally protects the flow components of the slurry in the double casing, and does not belong to wearing parts.
Therefore, most of our customers and end users slurry pump parts mentioned mouth is mainly refers to the slurry flow components is usually said four members namely: volute, impeller, front fender, rear guard board, in addition to packing boxes and slurry pump slurry pump expeller is often replaced.
      Slurry pump slurry pump parts is a core part of the operation is working directly with the transport slurry wetted parts, so wear is the largest and fastest-growing and most frequent replacement.
          2, liquid slurry composed of parts by parts of slurry pump, support, baffles, motor blocks and other accessories composition, its main feature is that we often say parts of slurry pump, but the shape and Horizontal slurry pumps are great differences, the following will be elaborated.


Second, the following mainly in slurry flow components made elaborate production process;
       1, the casting: modeling (sand, coated sand), smelting (the scrap melting and post-blast furnace stove testing, up to standard material); see indication map
            After a mold process, the existing mold to make the appropriate treatment to shape;
            Second, with the mold modeling;
                   It is simply to make a make a product similar model with a resin sand or other materials.
            Third, before casting preparations;
                   Use the previous model did make a corresponding shape inside the mold, removed after molding, brush material, fixed and so on.


 After casting furnace reaches a certain temperature, first with a small piece as a reference for laboratory tests in which the content, and then add other measures to enable the material to achieve the requirements of the standard material. Finally, do a good job before the riser poured into the mold inside.

Fifth, molding;
                   And other liquid inside the mold after a period of time taken to clean up the solidification molding;
                   Just good casting jacket


Sixth, in addition to sand processing;
                   Good casting slurry fittings except sand polished;

         2, heat treatment normalizing :(: increase the hardness of the casting blank achieve the desired state to a crystalline structure changes, increasing the wear properties; annealing: softens casting blank pieces, mainly used in slurry pump manufacturing process, sets turnbuckle when annealed, then processed and then normalizing reach hardness, tempering: the hardness has reached the ideal state of the crystal structure of parts caused by the secondary changes, so fitting a more uniform distribution of the material inside, so that the accessories more flexibility and corrosion resistant)

       First heat treatment - annealing: sand after processing products in addition to relatively brittle, to be annealed, is to be heated to a certain temperature parts for a period of time, so that hardness 40HR less easy to process and drilling;

          3, lathe: After the first heat, because it is blank, must be installed using a lathe has reached the size, if not the exact size can not be installed or is likely to cause large errors lead to shortened life of the installation, so this step must be professional The inspection of finished parts processed to detect, within a reasonable margin of error can be the next step. Slurry pump impeller part to be balanced and static balance processing, the overall structure of the impeller uniformly thereby reducing the incidence of vibration.


4, the second heat treatment
          Slurry pump parts for normalizing processing, the hardness standard hardness;
          5, three heat treatment
               Accessories for slurry tempering treatment, the slurry pump parts inside the crystal structure changes.

6, paint, brush oil processing;
        After more than a few programs you want to paint, brush oil operation, paint is used to prevent rust slurry storage accessories in the usual process and transport the first layer of protection. Brush oil is to enable the smooth non-corrosive and more compact in the assembly process.
         After the above process is completed if a customer as long as the parts can be shipped in accordance with the order, and if you need the whole pump requires further action.
          7, the assembly: the need for the entire pump accessories will be installed in accordance with the size of the installation procedure, if you only purchase flow components are not assembled in the late stage slurry process, mainly to replace the slurry flow components, the rest of the under normal use and maintenance generally change once a year.

8 :, test;
              Assembled pump to pressure test, leak testing and machine coordination. Testing to verify the quality of the slurry pump assembly to ensure that the user during use more secure.

       These are the slurry and slurry pump parts manufacturing process introduction, I hope you understand slurry production process help.
