Abstract

The invention discloses a mechanical seal chemical pump and a using method thereof. The mechanical seal chemical pump comprises a mounting base, two fixing bolt plates are fixedly mounted on each of the front surface and the rear surface of the mounting base, a first supporting frame is fixedly mounted at the position, close to one end, of the upper surface of the mounting base, a second supporting frame is fixedly mounted at the position, close to one side of the first supporting frame, of the upper surface of the mounting base, driving motors are fixedly mounted at the upper ends of the first supporting frame and the second supporting frame, and a third supporting frame is fixedly mounted at the side, close to the second supporting frame, of the upper surface of the mounting base. An impeller has the advantages of high heat resistance, chemical corrosion resistance, aging resistance, mildew resistance, ultraviolet radiation resistance, high density, high hardness and small size deformation, the tensile strength of the plastic material is increased, the durability of the impeller is improved, the service life of a chemical pump is prolonged, a pump cover, a first cylinder and a second cylinder are mechanically sealed, and the sealing performance and the suction force of the chemical pump are improved.

Description

technical field [0001] The invention relates to the technical field of chemical pumps, in particular to a mechanically sealed chemical pump and a use method thereof. Background technique [0002] Chemical pumps are widely used in industrial and urban water supply and drainage, and can also be used for irrigation and drainage of farmland and orchards. They are used to transport clean water or other liquids with similar physical and chemical properties to clean water. According to the process flow, pumps can be divided into: feed pumps, return pumps , circulating pumps, flushing pumps, sewage pumps, supplementary pumps, output pumps, etc.; according to public works, they can be divided into boiler pumps, cooling water tower pumps, fire pumps, deep well pumps for water sources, etc. Chemical pumps are widely used. [0003] Patent document (CN104121226A) discloses a chemical centrifugal pump. Including the impeller box, the impeller and the impeller shaft are arranged in the im...
