Abstract
A sludge pump is formed by a pump body, a blade wheel, a pump shaft, a pump cover and a mechanical seal moving ring, wherein the blade wheel is arranged inside a cavity formed by the pump body and the pump cover, and the blade wheel is installed at the left end of the pump shaft penetrating through the pump cover through a blade wheel nut. The mechanical seal moving ring is embedded in a groove at the back end of the blade wheel, a mechanical seal static ring is correspondingly arranged on the right side of the mechanical seal moving ring, the mechanical seal static ring is arranged on a static ring seat, a spring seat is arranged in an inner cavity formed by the static ring seat and a shaft sleeve, and a mechanical seal spring is arranged on the spring seat. Two ends of the pump shaft inside a suspension frame are respectively provided with a bearing. The sludge pump is stable in operation, low in noise, good in sealing effects, and long in service life.
Description
Technical field:
The utility model relates to a kind of pump, relates in particular to a kind of slurry pump.
Technical background:
