Benefits of technology
The present invention is about a plastic pump that has a fluorine resin lining only for the fluid transporting path, making it resistant to temperature and chemical reaction with the fluid, improving product quality and extending the lifespan of the pump.
Problems solved by technology
If the fluid transporting path is made of only a plastic material, the inside of the fluid transporting path may be easily deformed by the temperature based on the kinds (characteristics) of the fluid flowing through the fluid transporting path or may have a problem due to a chemical reaction with the fluid.
In order to prevent such a problem, the whole materials of the plastic pump may be made of a fluorine material, but in this case the manufacturing costs a lot.

Abstract
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.
Description
TECHNICAL FIELD[0001]The present invention relates to a plastic pump, and a method for manufacturing the same, and in particular to a plastic pump, and a method for manufacturing the same wherein a fluid transporting path of the inside of a plastic pump is lined with a fluorine resin, so the plastic pump will not be easily deformed by temperature based on the kinds of fluids, and the plastic pump is strong to any chemical reaction with fluid.BACKGROUND ART[0002]In recent years, a plastic pump the weight of which is lighter than a steel product is being used more and more thanks to the benefits resulting from is the decreased weight of the pump. In such a plastic pump, since a pump itself is made of a plastic material (PP, GFFRP), a fluid transporting path formed in the inside is also made of only a plastic material.[0003]If the fluid transporting path is made of only a plastic material, the inside of the fluid transporting path may be easily deformed by the temperature based on the ...
