Air Pulsation Damper: It is a empty container with pressure gauge on the top. It works by the air in the damper chamber. When the air in the damper is dissovled into the liquid, the efficency of the damper will be reduced. It is recommended to drain the liquid out of damper. The size air pulsation damper should be 26 times of each metering pump stroke capacity at least.

The bladder-type damper could be considered as the most traditional and widespread dampener, since it offers a great performance and is manufactured in a very wide range of sizes and building materials. Competitive in price, it is also easy to install. It is specially indicated for clean liquids without suspended solids and of low viscosity. It is manually adjustable and usually installed together with back pressure valves to guarantee the correct pressurisation of the air chamber in relation to the working pressure of the pump, being this assembly very common in diaphragm or piston metering pumps.

Low Price Automatic Tracer Dosing System Manufacturers and Suppliers in China. In order to control the corrosion and scaling of circulating water, it is usually achieved by adding a certain concentration of corrosion and scale inhibitors. In order to obtain good water treatment effect, besides selecting excellent formula, the key is to control the concentration (effective content) of water stabilizer within the specified range. At present, most domestic circulating water systems generally use manual dosing at regular intervals, and the effective value of the concentration of the chemicals in the water is obtained through analysis, and the opening of the metering pump is adjusted based on this. Or by measuring the amount of sewage discharge and water replenishment at the site, dosing the chemicals according to a certain proportion. Because of the large volume of the system, the lag of analysis data, the limited analysis frequency and the leakage of the system, it is still difficult to control the concentration of water stabilizer stably within the industrial index range. In view of the above problems and user requirements, our company designed a scheme of adding water treatment agent by using fluorescence tracer technology, which uses advanced tracer technology for automatic dosing. When you use this Automatic tracer dosing system, as long as the tracer produced by us is added to the water stabilizing agent used in your factory, your agent will become a tracer water treatment agent. During operation, it is only necessary to introduce the backwater of circulating water into the sampling water inlet of the controller. At this time, the effective components of the medicine in the water are monitored by the fluorescent tracer at any time, displayed on the display screen of the instrument and effectively controlled.
