The invention discloses a water pump impeller transmission shaft connecting structure and a sealed water pump. The water pump impeller transmission shaft connecting structure comprises a transmissionshaft, a sealing assembly, a cooling circulation assembly and a flange plate, a first shaft and a second shaft of the transmission shaft are fixedly connected, a movable ring and the second shaft arefixedly connected, a sliding ring and the second shaft are connected in a sliding mode, and a plate body of the flange plate is installed on the first shaft through a bearing. A limiting ring is fixedly connected with the plate body, a static ring of the sealing assembly is fixedly connected with the plate body, an inclined ring is installed on the static ring, a pressing disc is fixedly connectedwith the plate body and presses the static ring, a bent pipe and a liquid inlet pipe of the cooling circulation assembly communicate with the static ring, the liquid inlet pipe communicates with a cooling liquid tank through a pump body, and the bent pipe is placed in the cooling liquid tank. High-temperature water in the static ring flows down from the bent pipe, liquid in the cooling liquid tank is used for rapid cooling, the pump body can pump out the liquid in the cooling liquid tank and send the liquid back to the static ring through the liquid inlet pipe for cooling and lubricating, andtherefore the sealing assembly cannot be damaged due to the high temperature.
Description
technical field [0001] The invention relates to the technical field of water pumps, in particular to a connection structure of a water pump impeller drive shaft and a sealed water pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. [0003] The existing connecting structure of the transmission shaft and the water pump will generate a lot of heat due to friction during operation, and cannot be effectively cooled and lubricated, so that the sealing structure is easily damaged. Contents of the invention [0004] The purpose of the present invention is to provide a water pump impeller drive shaft connection structure and a sealed water pump, aiming to solve the problem that the existin...
