The importance of submersible pump characteristics
Thursday, 16 March 2017
At present, in the submersible pump fluid pipeline system, the control valve is the corresponding control components, the main role is to use isolation equipment and piping systems, adjust the flow, to prevent the return with the regulation of discharge pressure. It is important to choose the most suitable control valve for the piping system

What is the concentricity of the pump
Thursday, 16 February 2017
The concentricity of the pump is the coaxial degree of taking motor shaft as the active shaft and the pump shaft. When the pump and the motor shaft concentricity deviation is too large, the pump will be harmful. Long-term operation of the pump and the motor shaft is not the heart of its bearing (or

Analysis of Rotor Operation of Sewage Pump
Tuesday, 17 January 2017
The rotor of the sewage pump is rotated by the periodic transformation of a plurality of fixed volume transport units in the working chamber so as to change the volume of the sewage pump so as to constitute a higher vacuum and discharge pressure. The two rotors of the sewage pump are operated synchronously by
