Manual dosing device

The dosage and pressure of the dosing device can be selected according to the needs of the industrial process. The flow rate is from 1L / h to 8000L / h, and the pressure is from 0.1MPa to 25MPa. The metering accuracy of the metering pump can be as high as ± 1%, and multiple media can be transported at the same time and adjusted separately. The volume of the solution tank in the dosing device can be from 0.1 M3 to 20 m3, which can be selected according to the dosing amount. According to the different conveying media, there are a variety of materials to choose from, such as carbon steel (rubber lined carbon steel), stainless steel, non-metallic materials (PE, PVC, PP, PTFE), etc. The dosing device takes the metering pump as the main dosing equipment, and assembles the dissolving tank, agitator, dosing device, liquid level meter, safety valve, check valve, pressure gauge, filter, buffer, pipeline, valve, base, escalator, automatic monitoring system, power control system, etc. on a common platform according to the needs of process flow to form a module, namely the so-called skid mounted combined type Unit. The dosing device adopts Mechatronics structure, which can be divided into fixed type and mobile type (cart type) in terms of installation. Each type of dosing device is equipped with mixing system, dosing system and automatic control system. Several fixed skids can be combined into a whole. With the frequency conversion control system, local control, remote automatic control, manual and automatic conversion dosing can be realized. The utility model has the advantages of compact structure, small volume, low noise, stable operation, simple installation, convenient operation, etc.
