Description
technical field [0001] The invention relates to a pump, in particular to a chemical pump with cooling function and a manufacturing method thereof. Background technique [0002] Existing chemical pumps can satisfy pumping of low-temperature materials, but when pumping higher-temperature materials (such as above 200°C), heat transfer and friction will lead to high temperature of bearing lubricating oil, so bearing lockup or damage frequently occurs, so we A chemical pump with a cooling function is needed to solve the above problems and meet the needs of pumping high-temperature materials. Contents of the invention [0003] The object of the present invention is to provide a chemical pump with cooling function, which is used to solve the problem of pumping high-temperature materials. In order to achieve the above object, the present invention provides the following technical solutions: a chemical pump with a cooling function, including a motor and a pump body, the pump body ...
