High-pressure tangent pump

Abstract

The invention discloses a high-pressure tangent pump, which comprises a pump body, guide vanes, an impeller, an angular contact ball bearing, a shaft and a throat bush. 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.

Description

technical field [0001] The invention relates to the technical field of fluid conveying machinery, in particular to a high-pressure tangential pump. Background technique [0002] Petroleum, chemical, electric power, papermaking, pharmaceutical and food industries often have working conditions that require pumps to have small flow and high head characteristics, such as adding catalysts, etc., when traditional centrifugal pumps operate in areas that deviate from their optimal operating range , its operating efficiency will be greatly reduced, and it will generate relatively large vibration and noise. For the closed impeller, there are wear-resistant rings at the front and rear of the impeller. After the wear-resistant ring is worn, the performance of the pump will decline and cannot be adjusted. The axial force has high requirements on the shaft system, which may cause failures such as bearing heating. Contents of the invention [0003] The object of the present invention i...

[0002] Petroleum, chemical, electric power, papermaking, pharmaceutical and food industries often have working conditions that require pumps to have small flow and high head characteristics, such as adding catalysts, etc. When traditional centrifugal pumps operate in areas that deviate from their optimal operating range , its operating efficiency will be greatly reduced, and it will generate relatively large vibration and noise. For the closed impeller, there are wear-resistant rings at the front and back of the impeller. After the wear-resistant ring is worn, the performance of the pump will decline and cannot be adjusted. The axial force has high requirements on the shaft system, which may cause failures such as bearing heating
