Axial force self-balancing centrifugal chemical pump

Abstract

The invention discloses an axial force self-balancing centrifugal chemical pump, which belongs to the technical field of chemical pumps and includes a transmission assembly, a water channel assembly, and a supporting shaft assembly. In the water channel assembly, one end of the transmission assembly is provided with a supporting shaft assembly. The invention is scientific and reasonable, and safe and convenient to use. The internal elimination of the lateral vibration of the chemical pump greatly reduces the lateral vibration force of the chemical pump, which is beneficial to the maintenance of the ground and the working environment. The reset device of this device suddenly reduces the impact force on the face of the centrifugal impeller. The original state is restored under the tension of the return spring, and under the amplification effect of the unloading hemisphere and the unloading spiral groove, the reset process is carried out stably without vibration.

Description

technical field [0001] The invention relates to the technical field of chemical pumps, in particular to axial force self-balancing centrifugal chemical pumps. Background technique [0002] Because the liquid chemical raw materials have different densities in different parts, when the liquid chemical raw materials of different densities just enter the water inlet pipe, the lateral driving force on the centrifugal impeller is different, and when the liquid chemical raw materials are extracted, the liquid chemical raw materials at different depths The hydraulic pressure is also different, so that when the chemical pump pumps liquids at different depths, the lateral impact force of the liquid entering the chemical pump on the centrifugal impeller is also different. In addition, when the motor voltage is unstable, the centrifugal impeller speed instability will also cause centrifugation. The head-on thrust of the impeller is different. Due to the intermittent change of the pressu...

Problems solved by technology

[0002] Because the liquid chemical raw materials have different densities in different parts, when the liquid chemical raw materials of different densities just enter the water inlet pipe, the lateral driving force on the centrifugal impeller is different, and when the liquid chemical raw materials are extracted, the liquid chemical raw materials at different depths The hydraulic pressure is also different, so that when the chemical pump pumps liquids at different depths, the lateral impact force of the liquid entering the chemical pump on the centrifugal impeller is also different. In addition, when the motor voltage is unstable, the centrifugal impeller speed instability will also cause centrifugation. The head-on thrust of the impeller is different. Due to the intermittent change of the pressure of the pumped liquid, the intermittent change of the density of the pumped liquid, and the change of the voltage, the centrifugal impeller will be subjected to intermittent lateral thrust changes, which will cause the centrifugal impeller to drive the entire device to generate lateral vibration. The superposition of the former makes the lateral vibration frequency of the chemical pump higher, and the vibration will cause ground damage and noise pollution, so people need to provide axial force self-balancing centrifugal chemical pumps to solve the above problems
