When running dosing system should pay attention to what important matters? When running dosing system, pay attention to the following points: A. dosing pressure B. Stroke frequency C. Suction height D. Altitude E. Corrosive chemicals More: Provincia leads the new trend in the metrology field When metering pump outlet for atmospheric pressure, what measures can be taken to improve the pump repeat measurement accuracy? Installing the valve spring at the metering pump discharge valve improves repeat metering accuracy, but the most effective improvement is the installation of a backpressure valve at the end of the line. How to adjust the back pressure valve? 1. Never exceed the maximum working pressure of the metering pump. 2. When the dosing pump has pressure on the suction side, the pressure on the discharge side of the pump must be at least 1 bar higher than the pressure on the suction side. How to choose the right pulse damper volume? By multiplying the metering capacity (ml) per stroke of the metering pump (ml) by 26, the minimum volume (ml) of the pulsation dampener required to reduce the 90% pulsation can be obtained. How to set the pressure relief valve? The pressure of the safety valve can be adjusted within the range of the rated working pressure of the metering pump. It is not allowed to exceed the maximum working pressure of the metering pump. 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. What is the maximum allowable forward pressure when using ProMinent® metering pumps? The Alpha metering pump works properly when the forward pressure is less than 1 bar above the pump discharge pressure. If it exceeds the allowable pressure value, the metering pump can not work normally. If the delivery of liquid is not water, how to calculate the suction height? Divide the metering pump's nominal aspiration height by the specific gravity of the metering liquid. Under what circumstances with self-irrigation suction? Self-priming aspiration can be applied if: 1.Measurement of liquid volatile; 2. Measuring the proportion of liquid larger; 3. When higher stroke frequency is required; 4. Metering pump work in high altitude areas; 5. In the field of application requires a larger tank, and rely on the self-priming pump is not feasible.
