The pump body is connected with a pump cover. The pump cover is connected with a bearing bracket. The guide vanes are fixedly installed on the pump cover. The impeller is arranged between the guide vanes and the pump cover and is fixedly installed on the shaft. An adjusting sleeve is installed on one side of the impeller. The throat bush is fixedly installed on the pump cover through screws I. A deep groove ball bearing is installed on the shaft. The angular contact ball bearing is installed on the shaft through a round nut and a bearing cover. Bearing protectors are installed on one side of the bearing cover and the bearing bracket. The hydraulic model of the pump body and the impeller are designed by adopting a partial flow pump theory; the designed impeller blades effectively balance axial force and the service life of the bearing is prolonged; and the high-pressure tangent pump is suitable for working conditions of small flow and high lift, the operation stability is high, the efficiency is high and the energy is saved.
