Slurry Flow Measurement

Published on 2021/02/23

A slurry consists of a mixture of solids normally dissolved in water. Slurry flows are popular in many industries, including metals & mines, pulp & paper, and oil and gas. Industries face many problems when dealing with slurry due to its inconsistent composition. Equipment must be able to handle the slurry’s particles, but the various solids that flow through the mixture damage the equipment. In addition to being highly corrosive or at extreme temperatures, this problem makes precise slurry flow measurements impossible without the correct equipment.

A slurry pump is a machine that delivers fluids such as oil, water, acid and alkaline, emulsion, and fluid metal, fluids, gas mixtures, and solid-containing fluids. The slurry pump is normally lined with resilient materials, such as high-chromium alloys and rubber because they are more prone to the wear and corrosion of slurry during working. Slurry pumps are used for the transport of slurry containing abrasive solid particles in mines, power, metallurgy, coal, environmental protection, and other industries. Currently, approximately 80% of the slurry pumps applications are used in the mining industry.

For the selection of slurry pumps the fundamental knowledge of the industry, lift, and flow is required. Besides; the concentration of slurry, pipeline, pH, altitude, environmental temperature, and the temperature of slurry, etc., is also important to choose a slurry pump accurately. Depending upon their applications slurry pumps can be categorized as metering pumps and boiler feedwater pumps. They can also be divided into water pumps, oil pumps, mud pumps, etc. according to the type of liquid to be transported.
Based upon their working principle the industrial slurry pumps are divided into volumetric pumps, power pumps, and other types of pumps.

  1. Power pump/ Impeller pump/Vane pump are categorized into the axial flow pump, vortex pump, centrifugal pump, and partial flow pump. They are focused on the dynamic action of revolving impeller on liquid, constantly transferring energy to the liquid, consequently, kinetic energy and pressure of the liquid rises which then press out.
  2. The positive displacement pump is distinguished into the rotary pump and the reciprocating pump. The energy is regularly transferred to the liquid so that the fluid pressure rises to discharge the liquid forcefully.
  3. Other pumps provide energy in some other forms. The jet pump is centered on the high-speed working fluid to drain the fluid into the pump and combine it for energy exchange; the water hammer pump uses a portion of the water in the flow to transfer energy. In the electromagnetic power pump, the energy is powered by the action of the electromagnetic force.
