Product details
| 1、 Overview of Fully Automatic Medication Device Fully automatic dosing deviceAlso known as fully automatic dosing equipment, it has coagulants such as PAM and PAC, as well as slow-release scale inhibitors added to cooling circulating water. The two system control methods are different. The addition of flocculants is mainly quantitative, based on the alum flowers in the effluent after addition. The addition of slow-release scale inhibitors is mainly controlled by the conductivity of the pipeline system to control pipeline discharge. When the pipeline conductivity reaches the set parameters, automatic discharge is carried out. fully automaticDosing deviceMainly used for the treatment of water supply, boiler water, circulating water, wastewater, etc. in power plants, it can also be used in industries such as petroleum, chemical, environmental protection, and water supply systems. Unit combination dosing device, mainly consisting of solution tank, metering pumpfilterThe safety valve, check valve, pulse damper, water level gauge, control cabinet, etc. are integrated and installed on one base. Users only need to place the combined dosing device in the dosing room, connect the dosing pipe, and turn on the power to start and put it into operation. This factory style complete set of devices can greatly reduce the workload of design and on-site construction, providing reliable guarantees for the quality, safety, and on-site operation of the entire machine. 2、 Working principle of fully automatic dosing device Dosing deviceIt is mainly equipped with metering pumps, dissolving tanks, mixers, level gauges, safety valves, check valves, pressure gauges, etcfilterimplementBuffer, pipeline, valve, base, escalator, automatic monitoring system, power control system, etc. are assembled on a common platform according to the process requirements, using an electromechanical integrated structure. Each form of dosing device is equipped with a mixing system, dosing system, and automatic control system. It can achieve on-site control, remote automatic control, and manual and automatic interconversion of dosing. It has the advantages of compact structure, small volume, low noise, smooth operation, simple installation, and easy operation and use. The dosing device precisely prepares solutions of various solid and liquid chemicals through different process designs, and then accurately adds them using a metering pump to meet various design requirements. Such as descaling, deoxygenation, coagulation, acid addition, alkali addition, etc. The dosing process can be manually operated, or various electrical appliances and instruments such as PC, magnetic flap level gauge, pH meter, stroke controller, frequency converter, etc. can be used to make the dosing device an electromechanical integrated product and achieve automatic control. The dosage and pressure of the dosing device can be selected according to the needs of the industrial process, and a suitable metering pump can be chosen. Suitable products can be selected for flow rates ranging from 1L/h to 8000L/h and pressures ranging from 0.1MPa to 25MPa Measurement of metering pumpaccuracyIt can reach up to ± 1% and can achieve simultaneous transportation of multiple media, with individual adjustments. The volume of the solution tank in the dosing device can range from a minimum of 0.1m3 to 20m3, and can be selected according to the dosage. There are various materials to choose from depending on the conveying medium, such as carbon steel (carbon steel lining), stainless steel, non-metallic materials (PE, PVC, PP, PTFE), etc. 3、 Precautions for selection of fully automatic dosing device 1. When users choose a dosing device, the first step is to determine the amount of solution required by the system Select specifications (including metering pump parameters, mixing tank volume, solution tank volume, and on-site conditions), and then determine the dosing method based on the dosing situation (generally using the "one on one backup" or "multiple on one backup" method); 2. Select the materials of each component of the dosing device (stainless steel, carbon steel, non-metallic materials), the model of the metering pump (diaphragm pump, plunger pump), or the parameters of the dosing agent (name, concentration, temperature, density, viscosity, corrosiveness, etc.) as needed; 3. The ordering system includes several boxes and several pumps; 4. Is the metering pump a plunger pump or a diaphragm pump; 5. Measure pump flow and pressure; 6. Is the system manually controlled or automatically controlled; 7. Other special requirements for dosing devices. Dosing device, also known as dosing system or dosing equipment. 4、 Application fields of fully automatic dosing device The dosing device is a complete set of equipment that injects chemical solutions into various systems according to the process flow. The device can be divided into three categories according to the usage scenario. 1. Oilfield dosing device. Mainly used for injecting various chemicals such as coagulants, scale inhibitors, corrosion inhibitors, demulsifiers, etc. into the wellhead and other systems on the platform during oil extraction. 2. Boiler dosing device. It can be used for adding ammonia and hydrazine to boiler feedwater, condensate, shutdown protection, and adding phosphate to steam boilers. It is mainly used in power plants and power stations. 3. Water treatment dosing device. Add chemicals to tap water, wastewater, and sewage during the water treatment process. Mainly used for processes related to water supply and drainage treatment, environmental protection, etc. Such as waterworks, hotels, restaurants, swimming pools, and sewage treatment facilitieswater treatmentFactory, etc. |
