Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
Fig. 1 is a schematic structural diagram of a non-metal lining slurry inlet ring framework for a pump, which includes a metal framework layer 1 and a non-metal lining layer; the non-metal lining layer is filled and fixed on the inner surface of the metal framework layer 1; the inner space of the metal framework layer 1 is of a circular truncated cone-shaped structure, the inner surface of the metal framework layer 1 is sequentially provided with a first end surface 11, a second end surface 12 and a third end surface 13 from top to bottom, the lower part of the third end surface 13 is connected with a first groove 3, and a plurality of second grooves 4 are uniformly formed in the area between the first groove 3 and the bottom surface of the metal framework layer 1; the first end face 11 is provided with an exhaust hole 2, and the exhaust hole 2 penetrates through the first end face 11 and is communicated to the atmosphere; the connecting surface between the first end surface 11 and the second end surface 12 is parallel to the center line of the inner cavity of the metal framework layer; the connecting surface between the second end surface 12 and the third end surface 13 is inclined downwards along the direction far away from the center line of the inner cavity of the metal framework layer; the first end face 11 and the second end face 12 are both perpendicular to the center line of the inner cavity of the metal framework layer 1, and the third end face 13 is an arc-shaped transition face which is bent towards the center line of the inner cavity of the metal framework layer 1; the inner corners of the first groove 3 and the second groove 4 are fillets, and the outer corners between the first groove 3 and the inner surface of the metal framework layer 1 and between the second groove 4 and the inner surface of the metal framework layer are fillets, so that the release of the shrinkage force of the material is relieved in the casting and solidification links.
When the product is manufactured, firstly, a metal framework drawing is designed according to the size of a finished product of the slurry inlet ring part, structural model design and strength analysis are carried out by using software, then a slurry inlet ring metal framework blank is cast, heat treatment, surface shot blasting treatment and numerical control processing are carried out on the slurry inlet ring metal framework blank in sequence, and finally, full-size detection, strength detection and ultrasonic internal defect detection are carried out on a manufactured sample to determine the design of the metal framework drawing.
In the actual use process, the mortar inlet ring framework is subjected to sand blasting and is cleaned, then the mortar inlet ring and the casting mold are assembled together and are placed into a vacuum casting system, and simultaneously, the non-metal material is subjected to vacuum casting after being uniformly stirred in vacuum. The vacuum casting process is characterized in that casting is carried out in a vacuum environment, so that dust and impurities in air are prevented from entering the raw materials to influence the combination performance of the raw materials, and air residue in the raw materials is prevented from influencing the density of a cast finished product.
When the pump is used for entering the thick liquid ring during operation, the flow of thick liquid can produce very big frictional force, and frictional resistance can outwards pull the inside lining material layer, and non-metallic inside lining layer and advance the adhesive force between the thick liquid ring metal framework and be the key factor of resisting this kind of outside pulling force. This advance a thick liquid ring metal framework's special groove design, can advance thick liquid ring and do the non-metallic material inside lining when, non-metallic material at first can fill in special design's recess, and the non-metallic material in this special groove structure can grasp the inner liner simultaneously, makes it firmly attached to advance a thick liquid ring metal framework surface to improve the adhesion strength between inner liner and the metal framework.
When the non-metallic lining layer is produced, the end face and the edge of the slurry inlet ring are easy to have the defects of peeling, delaminating, cracking, air holes and the like. The special structural design and the vacuum casting preparation process of the slurry inlet ring metal framework can ensure that the non-metal material is smoothly fed, the exhaust is sufficient, and the non-metal lining layer has the defects of compact structure, no air holes, cracks, loose tissue and the like, so that the quality risks of peeling, delamination and the like are avoided, and the service life of the product is prolonged.
Before the design was applied, ten products were traced and tested, with tensile strengths of 11-13Mpa for the non-metallic material liner and the metal skeleton. The defect rate of cracking, delamination, air holes and the like on the end face and the edge of the slurry inlet ring is more than 85 percent. After the design is adopted, ten products are tracked and tested, and the tensile strength of the non-metal material lining and the metal framework is more than 22 Mpa. The defect rate of cracking, delamination, air holes and the like on the end face and the edge of the slurry inlet ring is less than 3 percent.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
