Fire pump high frequency work

When a fire pump is used to pump a slurry stream of liquid containing large, medium and small sizes of material, the liquid is tangentially injected into the cylindrical chamber to create a swirling flow and a portion of the liquid is tangentially removed from the chamber ; Injecting the slurry axially into the chamber, the vortex separating the oversize material from the rest of the slurry and liquid; axially removing the remaining slurry and liquid from the chamber and injecting it into the fire pump inlet; The material pumped out of the fire pump acts as a spray liquid forming the vortex to reduce wear on the fire pump impeller and increase fire pump efficiency. A method for reducing the wear of a fire pump impeller and increasing the efficiency of a fire pump when the fire pump is used to pump a stream of mud containing liquid of a large size to a small size in a liquid. The method comprises the steps of injecting liquid tangentially into a vortex chamber Forming a vortex and tangentially removing a portion of the liquid from the chamber; injecting the slurry axially into the chamber, the vortex separating the large size of the material from the remaining slurry and liquid; leaving the remaining Slurry and liquid are axially removed from the chamber and sprayed into an inlet of a fire pump; the material exiting the fire pump is used as a spray liquid to form the vortex; therefore, the large-sized material moves toward the vortex And as a result, medium and small sizes of material and liquid are injected into the fire pump, thereby reducing the wear of the impeller and allowing the pump to operate at a high speed, thereby improving the efficiency. Fire pump using a special hydraulic design and structural design, so that the flow pressure sub-file is more suitable than ordinary centrifugal water pump construction fire water supply system selection, flow-pressure curve without hump. High reliability due to wear-resistant, corrosion-resistant, anti-mesh materials for all parts that generate friction due to rotation. Multi-stage pump can be equipped with double water outlet, high load carrying capacity, strong anti-overload capability, .

CMC stands for carboxymethyl cellulose. However, CMC is more correctly the sodium salt of carboxymethyl cellulose.

CMC has the ability to impart viscosity to aqueous solutions. CMC is pseudoplastic , thixotropic and essentially non-thixotropic rheology by nature .By choosing the right cellulose gum type, the formulator has the ability to achieve the desired rheology for any aqueous system, including suspensions and emulsions. Besides controlling the rheology, CMC is also known for its excellent water retaining capacity.   

CMC used in tobacco industry as a viscose.

The CMC is used as a binder and a film-forming substance in regenerating tobacco to make tobacco, and is mixed with tobacco stems, tobacco leaves and the like, and rolled to prepare a flake yarn.
