New type of anti impurity vertical suspended semi submersible vertical turbine pump

A new type of anti impurity vertical suspended semi submersible vertical turbine pump, including a pump body, pump shaft, impeller, and guide vane; The pump shaft is rotatably arranged inside the pump body, and the impeller is fixed at the lower end of the pump shaft and rotates synchronously with the pump shaft inside the pump body. The guide vane is sleeved outside the pump shaft and located inside the pump body. The guide vane is located on the upper side of the impeller, and a guide bearing sleeve is fixed inside the guide vane. A shaft sleeve is fixed on the pump shaft, and a sealing ring is sandwiched between the lower inner wall of the guide bearing sleeve and the shaft sleeve. The upper inner wall of the guide bearing sleeve is sandwiched with a lower guide bearing in front of the shaft sleeve. By matching the guide bearing sleeve with the guide vane, in addition to the original shaft sleeve and lower guide bearing, a sealing ring is also installed inside the guide bearing sleeve to prevent impurities from entering the lower guide bearing and inner connecting pipe due to pump operation, greatly reducing the failure rate of water pump operation, increasing the service life of the water pump, and saving the cost of water pump use and maintenance.

Technical requirements: 1. A new type of anti impurity vertical suspended semi submersible vertical turbine pump, comprising a pump body, pump shaft, impeller, and guide vane; The pump shaft is rotatably arranged inside the pump body, and the impeller is fixed at the lower end of the pump shaft and located inside the pump body to rotate synchronously with the pump shaft.
