Problems solved by technology
[0003] Most of the existing centrifugal pumps are in direct contact with liquid during use, and are prone to corrosion after long-term use. The existing centrifugal pumps are not equipped with any anti-corrosion structures inside, resulting in poor overall anti-corrosion effects in the centrifugal pump. After a period of use , corrosion is prone to occur in the centrifugal pump, resulting in malfunctions in the centrifugal pump, and certain improvements are needed. Therefore, it is necessary to study a corrosion-resistant vertical centrifugal pump.

The invention belongs to the technical field of centrifugal pumps, particularly relates to a corrosion-resistant vertical centrifugal pump, and aims to solve the problems that an existing centrifugal pump is not internally provided with any corrosion-resistant structure, so that the overall corrosion-resistant effect in the centrifugal pump is poor, the interior of the centrifugal pump is prone to corrosion after being used for a period of time, and use faults occur in the centrifugal pump. According to the scheme, the corrosion-resistant vertical centrifugal pump comprises a box body, wherein a cover plate is rotationally connected to the outer wall of one side of the box body, a motor is fixedly connected to the top of the box body, a centrifugal box is arranged on the inner wall of the box body, a liquid inlet pipe and a liquid outlet pipe are arranged at the two ends of the centrifugal box respectively, and an equipment cavity is formed in the inner wall of the box body. The drying and anti-corrosion treatment effect of the fan blades can be further improved through the drying mechanism arranged at the bottom of the air inlet mechanism, the outer wall of the centrifugal box can be scraped through the scraping mechanism arranged on the outer wall of the centrifugal box, and impurity residues are avoided; and by arranging an anti-rust mechanism at the bottom of the centrifugal box, the corrosion resistance of the corrosion-resistant vertical centrifugal pump can be further improved.
Description
technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a corrosion-resistant vertical centrifugal pump. Background technique [0002] Centrifugal pumps work by rotating the impeller to cause the water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. It is suitable for industrial and urban water supply and drainage, pressurized water delivery for high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transportation, and HVAC refrigeration cycle. [0003] Most of the existing centrifugal pumps are in direct contact with liquid during use, and are prone to corrosion after long-term use. The existing centrifugal pum...
