Dosing device

Overview Generally, a complete system consists of one tank, two pumps, and one electric agitator. It can also be configured as two tanks with two pumps, two tanks with multiple pumps, or multiple tanks with multiple pumps based on user requirements. It is suitable for the preparation and quantitative dosing of liquid-liquid, solid-liquid, and gas-liquid chemical solutions. Main Features - Fully functional configuration with high safety and stable performance - Modular design for easy transportation, installation, and maintenance - Independent electrical control cabinet for convenient installation and debugging (remote/automatic control options available) Main Materials - Tank material: PE, carbon steel, carbon steel with rubber lining, 304/316 stainless steel - Agitator material: carbon steel, carbon steel with rubber lining, 304 stainless steel, 316 stainless steel - Metering pump fluid contact materials: UPVC, PVDF, carbon steel, 304 stainless steel, 316 stainless steel System Diagram System Diagram (Two Tanks, Three Pumps — Two in Use, One Standby) Metering Pump Flow Adjustment Methods: 1. Manual stroke adjustment 2. Frequency conversion speed adjustment 3. Electric stroke adjustment Main Applications (1) Power plant in-furnace dosing: ammonia dosing in feedwater, hydrazine dosing, phosphate dosing in boiler water, coordinated phosphate treatment, ammonia dosing in condensate water, etc. (2) Power plant external dosing: coagulant dosing in raw water, flocculant aid dosing, stabilizer (corrosion inhibitor) dosing in circulating water, scale inhibitor dosing, biocide dosing, ammonia dosing in startup boiler rooms, phosphate dosing in startup boiler rooms, ferrous sulfate coating in condensers, etc. (3) Water treatment dosing: flocculant dosing in wastewater, coagulant aid dosing, antifoam agent dosing, etc. Technical Parameters Table | Model | HLJYJ-500 | HLJYJ-1000 | HLJYJ-2×1000 | HLJYJ-1500 | HLJYJ-2×1500 | |-----------------|-----------|------------|--------------|------------|--------------| | Applicable Unit | <125MW | 125–200MW | 200–300MW | 300–600MW | | | Dimensions (mm) | 1450×2100×2400 | 2100×2500×2400 | 2400×3700×2400 | 2400×3000×2400 | 2800×4500×2400 | | Unit Configuration | 1 tank, 2 pumps | 1 tank, 2 pumps | 1 tank, 3 pumps | 2 tanks, 2 pumps | 2 tanks, 3 pumps | 2 tanks, 4 pumps | 1 tank, 2 pumps | 1 tank, 3 pumps | 2 tanks, 2 pumps | 2 tanks, 3 pumps | 2 tanks, 4 pumps | | Number of Units | 1, 2 | 1 | 2 | 1, 2 | 2, 3 | 2, 3, 4 | 1, 2 | 2 | 1, 2 | 2, 3 | 2, 3, 4 | | Tank Volume | 0.5 m³ | 1 m³ | 1 m³ | 1.5 m³ | 1.5 m³ | | Control Mode | Manual/Auto | Manual/Auto | Manual/Auto | Manual/Auto | Manual/Auto | | Load Power | Total load = 1.5 × (sum of metering pump power + sum of agitator motor power). Metering pump power refers to the table below; agitator power is generally 0.55–1.1 kW. Note: 1. Some parameters in the table can be customized according to user requirements. 2.
