Abstract
The utility model discloses a high pressure tangent pump which comprises a pump body, a guide vane, an impeller, an angular contact ball bearing, a shaft and a throat bushing. The pump body is connected with a pump cover. The pump cover is connected with a bearing frame. The guide vane is fixedly placed on the pump cover. The impeller is placed between the guide vane and the pump cover, and is fixedly placed on the shaft. One side of the impeller is provided with an adjusting sleeve. The throat bushing is fixedly placed on the pump cover through a first screw. A deep groove ball bearing is placed on the shaft. The angular contact ball bearing is placed on the shaft through a round nut and a bearing pressing cover. A bearing protector is placed on one sides of the bearing pressing cover and the bearing frame. Hydraulic models of the pump body and the impeller are designed by adopting the partial emission pump theory; and the design of impeller blades effectively balances axial force and prolongs service life of the bearing. The high pressure tangent pump is applied to working conditions with small flow and high-lift features, stable in operation, high-efficient and energy-saving.
