PLASTIC PUMP, AND METHOD FOR MANUFACTURING SAME |
摘要 |
The present invention relates to a plastic pump and to a method for manufacturing same. The method includes: a pre-manufacturing step for pre-manufacturing an inner body and impeller formed from a fluorine resin material by means of injection molding; a body manufacturing step for manufacturing a complete body, in which the inner body is formed from a fluorine resin and the outer body is formed from a plastic material, by molding the plastic material in a first mold after fixing the pre-manufactured inner body to the first mold; a cover manufacturing step for manufacturing an impeller cover, which is formed from a plastic material, by molding the plastic material in a second mold so as to protect the manufactured impeller; and a finishing step for completing the plastic pump by sequentially assembling the manufactured complete body, the impeller, and the impeller cover. According to the present invention, only a fluid transporting path is lined with the fluorine resin and is thus not easily deformed by temperature regardless of the type of fluid and is resistant to a chemical reaction with a fluid for improved product quality and significant extension of the period over which the pump can be used. |

1. A method for manufacturing a plastic pump, comprising:
a pre manufacturing step wherein an inner body made of a fluorine resin material and forming a fluid transporting path and an impeller engaged to the inner body are previously manufactured through an injection mold method; a body manufacturing step wherein for manufacturing a complete body, in which the inner body is formed from a fluorine resin and the outer body is formed from a plastic material, by molding the plastic material in a first mold after fixing the pre-manufactured inner body to the first mold; a cover manufacturing step wherein for manufacturing impeller cover, which is formed a plastic material, by molding the plastic material in a second mold so as to protect the manufactured impeller; and a finishing step wherein for completing a plastic pump by sequentially assembling the manufactured complete body, the impeller and the impeller cover. |
