Description

Technical Field

[0001] This utility model belongs to the field of centrifugal pump technology, and in particular relates to a centrifugal pump that is easy to clean. Background Technology

[0002] A centrifugal pump is a pump that uses the centrifugal force generated by the rotation of an impeller to transport liquids. In operation, before starting the pump, the pump casing and suction pipe are filled with water. Then, the motor is started, causing the pump shaft to drive the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown towards the outer edge of the impeller, thus creating a low pressure at the center of the impeller. The liquid in the low-level tank is thus continuously drawn up and discharged through the flow channel of the volute pump body. Due to the complex water environment, impurities may be mixed in the water. If these impurities enter the pump body, they may cause damage to the pump body. Therefore, a cleaning device is installed at the inlet end of the centrifugal pump.

[0003] In existing cleaning devices, impurities continuously accumulate during use, requiring regular maintenance. However, existing cleaning devices are not convenient for cleaning the filter, resulting in reduced maintenance efficiency. Therefore, we provide a centrifugal pump that is easy to clean to solve the above-mentioned problems. Utility Model Content
