Dosing metering pump precautions

Dosing metering pump is a can meet a variety of strict process needs, the flow rate can be adjusted in the range of 0-100% stepless, used to transport liquid (especially corrosive liquids) a special Positive displacement pump. Xiaobian now to introduce the dosing pump under the use of what considerations. Dosing dosing pump dosing dosing pump precautions 1, when running dosing metering pumps should pay attention to what important matters? Dosing pressure, stroke frequency, suction height, altitude, chemical corrosion. 2, when the dosing pump outlet at atmospheric pressure, what can be done to improve the pump repeat metering accuracy? Valve metering valve to install the valve discharge spring can improve the accuracy of double counting, but the most effective way to improve the pipeline is installed at the end of a Back pressure valve. 3, how to adjust the dosing valve back pressure valve? 1) When the metering pump pressure in the suction side, the discharge pressure of the pump at least 1bar higher than the suction pressure. 2) Never exceed the maximum working pressure of the metering pump. 4, if the delivery of liquid is not water, dosing metering pump suction height how to calculate? The metering pump rated suction height divided by the proportion of liquid measurement. 5. How to set the pressure of dosing pump safety valve? The pressure of safety valve can be adjusted within the range of rated working pressure of metering pump. The maximum working pressure of metering pump should not be exceeded. The safety valve is designed to prevent over-pressurization of the metering pump. For example, if the maximum working pressure of the metering pump is 3 bar, the relief valve pressure should be set at 3 bar, or lower to ensure proper operation of the metering pump. Overpressure is one of the major causes of dosing pump damage. 6, how to choose the appropriate dosing metering pump pulse damper volume? By measuring the metering pump capacity of each stroke (ml) multiplied by 26, can be obtained by reducing the minimum pulse pulsator 90% of the minimum volume (ml). 7) Under what conditions is self-priming aspiration? 1) The liquid being metered is easily volatile; 2) The metered liquid has a high specific gravity; 3) When a higher stroke frequency is required; 4) When the metering pump is operating in a high altitude area ; 5) In the field application requires a larger tank, and rely on the self-priming pump is not feasible. 8, can give some advice on the choice of dosing pump head pump? Involved in the chemical pump head / seal corrosion, what problems usually occur, should be avoided? In relation to the dosing metering The usual problem with a pump head is the presence of acid, chlorine, fluoride and hydrogen peroxide. Due to the different drug concentration and operating temperature, it is difficult to determine the specific pump head material. When measuring fluoride, we recommend selecting a Viton® sealed PVC pump head. For most chlorination applications, it is best to choose an EPDM sealed NP (Plexiglas) pump head. For hydrogen peroxide mixtures, only PTFE-sealed PTFE or stainless steel pump heads can be selected. Concentrated hydrochloric acid is usually selected Viton? Sealed plexiglass pump head. Concentrated sulfuric acid can be selected PTFE sealed PTFE pump head. Manufacturers of chemicals may give advice or consult ProMinent ™ chemical preservative charts to determine the compatibility of chemicals with contact materials. 9, in the dosing pump head measurement of liquid, which factors must be considered? The main factors considered are the liquid viscosity, specific gravity, vapor pressure and temperature. Above is the fluid network in Asia to bring you the dosing pump instructions for the use of the introduction, I hope you know the dosing pump help. (Editor: Xiaoxia)

INCOLOY®

The registered trademark name, Incoloy, is applied as the prefix name to several highly corrosion resistant high temperature strength metal alloys produced by Special Metals Corporation. These Incoloy alloys or superalloys are nickel-based alloys that exhibit traits that include good corrosion resistance in aqueous environments, excellent strength and oxidation resistance in high-temperature settings, good creep-rupture strength, and ease of fabrication.

Alloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternatives to the various Incoloy brand alloys.

The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product. Chemical and petrochemical processing, power plants, and oil and gas industries widely use these superalloys.
