Pump industry suppliers - Avoid chemical pump cavitation can choose the way

chemical pump puzzle in the design of effective sealing, exquisite production and processing, the assembly line is in good condition, rotational speed is higher, the riddle house seal effect is very good. Packing seal is an expansion and back stretch packing in the packing box, with radial clamping force of conversion for axial sealing force, which has a sealing effect. This kind of way of seal is called packing seal, this kind of packing is called packing. Because packing seal structure simple, fire pump wholesale, changing a convenient, high quality and low price, into the speed ratio, working pressure, material widely and widely in chemical pump design scheme selection.

chemical pump when operating with drive seal, the tension caused by the equilibrium in the Lord, vice impeller impeller outlet high pressure liquid, ShouYang fire pump, gradually realize the seal. When parking, vice impeller failure, so be sure to configure other parking sealing equipment when handling parking will be caused by the chemical pump leakage. Impeller inlet pressure of work has fallen sharply, sucked into the ability to work, the greater the bubble in but if less than the saturated vapor pressure and dissolved gas in the liquid also escape, originally this small bubbles with cyclone flow in the impeller high pressure area under the high work stress in the surrounding liquid effect, will be frozen again, smaller volume, and as to produce a cavitation, by this time the surrounding liquid and at very high speed operation to cavitation and part of the high work pressure, continue to tap the impeller surface, such as high speed, high pressure hydraulic power impact, leaf surface corrosion due to exhaustion show black spots, honeycomb cellular.

avoid chemical water pump cavitation can choose the way:

(1) improve chemical water pump's cavitation characteristics of resisting countermeasures: the countermeasures of the key is to rely on design and manufacturing enterprises to maintain, such as to change the impeller inlet geometry appearance, selects the double suction impeller, can also use the lower impeller flow rate, increased channel impeller diameter.

2 lifting equipment limited NPSH, such as expanding the absorption into the working pressure on the tank level, effectively clear geometric installation height to width ratio, can lift pump NPSH reasonably. Moderately expand leaves over the total width, can also lower the normal acceleration impeller channel.

(3) selection of cavitation erosion resistance materials manufacturing impeller.

(4) lower inlet pipe friction damage, reduce the level of gasification working pressure, can promote rational NPSH.
