| The dosing device is also called dosing system and equipment. According to the technological process, the complete set of devices for injecting chemical liquid into various systems is called dosing device, which can be divided into three categories according to the application situation. 1銆?a href="/dosing-equipment/boiler-dosing-equipment.html" target="_blank"Boiler dosing device It can be used for feedwater ammonia and hydrazine addition, condensate ammonia addition and hydrazine addition, furnace shutdown protection ammonia addition and hydrazine addition, and phosphate addition to steam boilers, mainly for power plants and power stations. 2銆丱ilfield dosing device. It is mainly used to inject flocculants, scale inhibitors, corrosion inhibitors, demulsifiers and other liquid medicines into wellhead and other systems of platform in oil exploitation. 3銆丏rug-adding device for water treatment. Drugs are added to tap water, wastewater and sewage in the process of water treatment. Mainly used for water supply and drainage treatment, environmental protection and other processes. Such as waterworks, hotels, restaurants, swimming pools, sewage treatment plants, etc. The working principle and characteristics of the dosing device are as follows: BHJY-series dosing device is an excellent product produced by our factory. It takes metering pump as main dosing equipment, and assembles the dosing box, agitator, level gauge, safety valve, check valve, pressure gauge, filter, buffer, pipeline, valve, base, escalator, automatic monitoring system and power control system on a public platform according to the process requirements. A module, the so-called skid-mounted modular unit. BHJY-series dosing devices adopt the structure of mechatronics, which can be divided into fixed and mobile (cart type) in installation. Each type of dosing device is equipped with mixing system, dosing system and automatic control system. Several fixed pry-ups can be combined into a whole. With frequency conversion control system, local control, remote automatic control, manual and automatic reciprocal dosing can be realized. The utility model has the advantages of compact structure, small volume, low noise, stable operation, simple installation, convenient operation and use, etc. Through different process design, the dosing device accurately configures the solutions of various solid and liquid chemicals, and then accurately feeds them with metering pumps to meet various design requirements. Such as scale removal, oxygen removal, coagulation, acid addition, alkali addition, etc. The dosing process can be operated manually, and the dosing device can be automatically controlled by means of various electrical appliances such as PC, magnetic tilting plate level gauge, PH meter, stroke controller, frequency converter and so on. The dosing process can be operated manually, and the dosing device can be automatically controlled by means of various electrical appliances such as PC, magnetic tilting plate level gauge, PH meter, stroke controller, frequency converter and so on. The volume of the solution box in the dosing device can be from 0.1 M3 to 20 m3. It can be selected according to the dosing amount. According to the different medium of transportation, there are many kinds of materials to choose, such as carbon steel (carbon steel lining), stainless steel, non-metallic materials (PE, PVC, PP, PTFE), etc. Notices for Selection of Drug Adding Device 1銆乄hen the user chooses the dosing device, he first determines the selection specifications (including pump parameters, mixing tank volume, solution tank volume and site conditions) according to the dosing requirements of the system, and then determines the dosing mode according to the dosing conditions (generally using the "one-on-one" or more-on-one-on-one-off mode); 2銆丼elect the material (stainless steel, carbon steel, non-metallic material) of each component of the dosing device, the type of metering pump (diaphragm pump, plunger pump) or provide the parameters (name, concentration, temperature, density, viscosity, corrosiveness, etc.) of the dosing device to our company. 3銆丱ther Special Requirements for Drug Adding DevicesChina Dosing Equipment factory website:http://www.sf-chemy.com/dosing-equipment/ |
