Description

Technical Field

[0001] The present application relates to the technical field of pulp pumps, and in particular to a shock-absorbing pulp pump. Background Art

[0002] Pulp pump is a kind of machine widely used in papermaking industry. Pulp pump is used to realize the transportation of pulp. According to the different mass concentration of pulp, it is usually divided into low-concentration pulp pump (concentration less than 7%), medium-concentration pulp pump (concentration between 7% and 15%) and high-concentration pulp pump (concentration greater than 15%). The existing two-phase flow pulp pump adopts the principle of "relative suction and relative blocking" in the two-phase flow theory to carry out the hydraulic design of the pump, so that the hydraulic performance of the flow-through components of the pump conforms to the law of solid-liquid two-phase flow, thereby reducing the scouring and wear of the flow-through components by the slurry, and greatly improving the working efficiency and service life of the pump.

[0003] The patent document with the announcement number CN209025891U that has been published discloses a pulp pump with a shock absorber, which belongs to the technical field of pulp pumps, including a pulp pump body and a shock absorber. A discharge pipe is connected to one side of the pulp pump body. The shock absorber includes two connecting flanges, a rubber tube, a pipe support plate, a support plate support seat, a hydraulic damper, a base and a support foot. The rubber tube connects the two connecting flanges, and the shock absorber is connected to the discharge pipe through the connecting flange. The pipe support plate is respectively nested in the outer wall of the limit ring of the two connecting flanges, the support plate support seat is welded to the bottom of the pipe support plate, a base is provided under the support plate support seat, a support foot is fixed at the bottom of the base, and the hydraulic damper is fixed between the base and the support plate support seat.
