Abstract

The invention discloses a mechanical sealing device for a water jetting propeller pump. The mechanical sealing device comprises a mounting flange, a static ring assembly and a dynamic ring assembly which are sequentially arranged on a rotating shaft in a sleeving manner, a mounting shaft is arranged at the end, close to the static ring assembly, of the mounting flange, one end of the static ring assembly is installed on the mounting shaft in sliding, sealed and sleeving manners, an elastic compensating component is arranged between the end surface of the static ring assembly and the end surface of the mounting shaft, and a limit retaining spring is further arranged on the static ring assembly to be used for preventing the static ring assembly from leaving the mounting shaft; the exterior of the end, close to the mounting shaft, of the static ring assembly is sleeved with a rubber corrugated pipe, and the other end of the rubber corrugated pipe is connected to the mounting flange; and the dynamic ring assembly and the rotating shaft in driven connection through a transmission pin, and the friction surface of the dynamic ring assembly is attached to the other end face of the static ring assembly to form a sealed grinding surface. The mechanical sealing device for the water jetting propeller pump has the advantages of being simple in structure and good in sealing performance and being capable of effectively preventing sediment from entering a sealing seat, damaging the sealing ring and destroying the sealing surface.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a mechanical seal device for a water jet propulsion pump. Background technique [0002] The jet propeller is a new type of propulsion tool for ships, which is used to propel ships together with the ship's power plant. The water jet propeller is a kind of propeller in which the jet part of the propulsion mechanism is immersed in water, and the reaction force generated by the jet water is used to drive the ship forward. It is composed of water pump, pipeline, suction port and spout, etc., and can change the jetting direction of water flow through the spout to realize the manipulation of the ship. The water jet propeller is powered by a water pump, sucks water from the bottom hole of the ship, and discharges the water from the rear direction of the ship through the side pipe, and propels the ship by the reaction force of the water. [0003] The seal of the pump bearing bo...
