Selection of metering pumps metering pumps appropriately selected point what information is required? 1. metered flow of liquid. 2. The metered main characteristics of the liquid, such as chemical resistance, viscosity and specific gravity. 3. The system back pressure. 4. suitable suction lift. 5. Other options metering pump type required, such as analog control, pulse volume control, flow monitoring and timer. ? Solenoid driven metering pump What are the main advantages of the solenoid driven metering pump has only one moving part - the armature shaft. Generally, the more reliable metering pump model, the more moving parts at least metering pump. Metering pumps are suitable for low flow, low pressure in the workplace, and a good compensation when the supply voltage fluctuations. And fixed frequency, change the metering pump stroke length compared metering pumps, fixed stroke length, changing the frequency of the metering pump What are the advantages? By correction, the dosage of each stroke is known. Therefore, the total dosage can be calculated (dosage = dosage per stroke * frequency). The total dosage and frequency linear relationship (0.5 dosage frequency = 0.5). By an external pulse or analog control, dosage may be within one second from the minimum to maximum. Further than the motor drive stroke length adjustment costs to be much lower. How to use the metering pump performance curve? 1. Find the selected metering pump corresponding performance curve. 2. In the following charts indicate the current back pressure. 3. Determine the correction factor, back pressure values ??take BAR units, extending up to the curve, the vertical readout correction factor values ??left at the intersection. 4. The calculation results in an intermediate dosage scale. 5. When this value is placed on the dosage scale, you can use a ruler to find the stroke length setting and stroke frequency settings. Integrated automatic dosing unit Changzhou City, Xiao source Machinery Co., Ltd. is an administration tool, stirring, transmission fluid, automatic control in one complete set of equipment for the needs adding corrosion inhibitors, scale, fungicides The circulating water system metering pump accessories, water quality processing of accurate dosing and metering agent. In the water supply, wastewater treatment process, often adding a variety of chemical agents as scale, biocide, coagulation, flocculation with, in order to achieve the purpose of purifying water. These agents have solid particles, liquid, adding the process must be dissolved, and diluted by adding quantitative ratio in order to obtain the best results, so the dissolved drug dosing device is commonly used in water treatment engineering equipment. Automatic dosing device by the metering pump, the pot, blender, stand, cabinet and other components, is the foundation of our company is equipped with metering pump, combined with the actual situation of the development of the domestic water system, advanced water treatment system to automatically increase equipment and medicine.
