Peak Value Dispersion Technology in Reciprocating Pumps for Pulp Transportation

The peak value dispersion technology in reciprocating pumps for pulp transportation is described systemically . On the premise of analyzing the cause of flow pulsation and pressure pulsation of single reciprocating pump, the cause of peak value overlapping in pulp transporting to one pipeline with multi-unit pumps, and the two conditions to eliminate peak overlapping are discussed ; the graphic analysis of distinguishing optimum dispersion phase angle, the two methods and the formula of software calculation and judgment are gived; the concept of peak value dispersion technology and the methods of mechanical coupling and electron coupling are put forward ; and finally, the practical plan and operation situation of the peak value dispersion technology in high pressure reciprocating diaphragm pump units for alumina solving off pipeline of the technical renovation project of Henan Company of Chalco are described.
