The functional characteristics of the dosing device and how to select the automatic dosing device?

1. Corrosion: In the circulation of cooling water, the water is in good contact with the air in the automatic dosing device, which makes the dissolved oxygen in the water oversaturated, and the dissolved oxygen in the water will cause corrosion of metal pipes such as carbon steel and cast iron. 2. Scaling:

The water is continuously evaporated in the automatic dosing device, which greatly increases the salt content in the circulating water, and the calcium carbonate and carbonate in the water greatly increase, resulting in scaling on the surface of the pipeline and uneven surface heat exchange. 3. Slime scale: The cooling water absorbs a large amount of dust, sediment, microorganisms and other inorganic organic substances in the air, because the light, temperature and oxygen in the cooling tower are very suitable for the growth of bacteria and algae, so that the slime in the system increases and causes the harm of the system.

With system design as the main body, it overcomes the defects of poor systematization of traditional products with a single equipment or component as the main design body;

Absorb the essence of dosing technology at home and abroad, and optimize the process with a new design concept;

The modular design of the product structure and the integrated combination can easily expand the capacity and function;

According to different water quality and different requirements of users, the best scheme can be flexibly configured;

A variety of well-known brands at home and abroad, different materials, various grades of equipment and components, users can choose at will;

You can choose a variety of control methods such as manual and automatic to achieve different control requirements.

The automatic dosing device is composed of a metering pump as the main dosing equipment, a dissolving medicine tank, a stirrer, a liquid level gauge, a safety valve, a check valve, a pressure gauge, a filter, a buffer, a pipeline, a valve, an automatic monitoring system, an electric power control system, etc.

Dosing according to the working parameters in the flotation process is an important process component to ensure the yield and rate of flotation concentrate. It is necessary to control the automatic addition of agents, ensure the accuracy and accuracy of dosing, ensure the rationality of process conditions and dosing, and avoid wasting agents and increasing production costs.

To this end, the ZNJY-GM intelligent dosing system developed by Shandong University of Technology Zhongneng Technology Co., Ltd. can be widely used in the automatic control of flotation dosing in mining enterprises. The precise dosing of flotation is realized through the control of ZNJY-GM intelligent dosing system, which is conducive to ensuring the concentrate yield and the highest rate index. At the same time, the ZNJY-GM intelligent dosing system can be integrated into the automatic control system of the concentrator and become a control split of the automatic control system of the concentrator.

The ZNJY-GM intelligent dosing system is composed of a control host, a diaphragm metering pump, a pharmaceutical tank and related pharmaceutical pipelines. The dosing amount of each point is set by the control host, and the dosing metering pump of each dosing is controlled by the control host, so as to realize and complete the control requirements of the process for the dosing amount of each dosing point.

The ZNJY-GM intelligent dosing system selects the diaphragm metering pump as the execution equipment unit for dosing. As an ideal equipment for precision metering and dosing of fluids, the diaphragm metering pump uses a specially designed and processed flexible diaphragm to replace the piston, and realizes reciprocating motion under the action of the driving mechanism to complete the suction and discharge process.

Due to the isolation effect of the diaphragm, the isolation between the metered fluid and the driving lubrication mechanism is truly realized in the structure. The agent is closed throughout the conveying process and will not come into contact with any object, so it will not pollute and corrode the outside world, making the whole dosing process extremely environmentally friendly.

The ZNJY-GM intelligent dosing system can realize local operation through the touch screen on the local control box; At the same time, the ZNJY-GM intelligent dosing system has the function of networking, and can also realize remote monitoring and remote control operation.

It should be determined according to the dosage of powder provided, the maximum amount of liquid medicine to be prepared per hour.

It should also be noted that the dosage of the agent can be accurately adjusted to ensure the treatment effect and avoid waste, and the stainless steel shell is easy to maintain.

1. When the user selects the dosing device, the selection specifications are determined according to the amount of solution required by the system (including metering pump parameters, stirring box volume, solution tank volume and field strips).

pieces), and then according to the dosing situation, determine the dosing situation, determine the dosing method 2, and select the material (stainless steel, carbon steel, non-metallic materials) and metering pump model of each part of the dosing device according to the need. Parameters of the agent (name, concentration, temperature, density, viscosity, corrosivity, etc.).

The purchase of equipment is to solve the problem, it is recommended to consult relevant manufacturers, such as Wujiang Environmental Protection, Soderman, Yuanqi, etc., to provide technical support, so as not to spend money and energy and get the desired effect.

The Hank Eco-Friendly Dosing Device can be customized in size as required.
