Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a loose fiber dyeing water pump device. Background Art

[0002] During the dyeing process in textile factories, dye often has difficulty transferring color to areas where the fabric is concentrated due to poor dye flow in the dye vat, resulting in poor dyeing quality. Therefore, dyeing machines are widely used. These machines are suitable for dyeing, bleaching, scouring, and washing animal fibers such as cashmere and wool, plant fibers such as cotton, and synthetic fibers. These machines automatically agitate the fabric in forward and reverse cycles at set times. A loose fiber dyeing machine is one type of dyeing machine.

[0003] Existing dyeing devices are all equipped with a dyeing water pump, which consists of a pump casing, an impeller, and a pump shaft. The impeller is located within the pump casing and is mounted on the pump shaft via a key to secure it radially. A lock nut is screwed onto the end of the pump shaft to compress the impeller, securing it axially. The pump shaft passes through the pump casing end cover. However, existing water pumps generally have the problem of high head and low flow rate. Therefore, when the dye flow rate is high, existing water pumps are insufficient to cope with the high flow rate during dyeing. This can easily damage the fiber strength and cause uneven dyeing, thereby reducing product quality. Summary of the Invention
