Introduction to Dosing Devices:

    The integrated dosing device uses a metering pump as the main dosing equipment, assembling components such as solution tanks, agitators, dosing devices, level gauges, safety valves, check valves, pressure gauges, filters, buffers, pipelines, valves, bases, ladders, automatic monitoring systems, and electrical control systems onto a common platform according to process requirements, forming a module known as a skid-mounted combined unit. 　　 

    The dosing device adopts an integrated electromechanical structure and can be categorized into fixed and mobile (cart-type) types based on installation. Each type of dosing device is equipped with an agitation system, dosing system, and automatic control system. Multiple fixed skid-mounted units can be combined into a whole, and with the addition of a frequency conversion control system, local control, remote automatic control, and manual/automatic switching for dosing can be achieved. It features a compact structure, small size, low noise, stable operation, simple installation, and ease of use. 　　 

    Through different process designs, the dosing device precisely configures solutions of various solid and liquid chemicals, which are then accurately dosed using metering pumps to meet various design requirements, such as descaling, deoxygenation, coagulation, acid addition, and alkali addition. The dosing process can be manually operated or automated through various electrical devices and instruments, such as PCs, magnetic flap level gauges, pH meters, stroke controllers, and frequency converters, making the dosing device an integrated electromechanical product for automatic control. 　　 

    The dosing volume and pressure of the dosing device can be selected based on industrial process requirements by choosing an appropriate metering pump. Flow rates ranging from 1L/h to 8000L/h, and pressures from 0.1MPa to 25MPa can be accommodated with suitable products. The metering accuracy of the pump can reach up to ±1%, and it can handle multiple media simultaneously with individual adjustments. The solution tank capacity in the dosing device can range from a minimum of 0.1m3 to 20m3, selected based on dosing requirements. Various materials are available depending on the medium being transported, such as carbon steel (rubber-lined carbon steel), stainless steel, and non-metallic materials (PE, PVC, PP, PTFE).
