1、 Equipment name: dosing device

2、 Specification and model: hdn

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

An automatic dosing product developed and produced by the dosing device is mainly used for the treatment of boiler feed water, circulating water, hydrazine, phosphate, etc. of the power plant, as well as the industries of petroleum, chemical industry, environmental protection, water supply system, etc. The unit combined dosing device is mainly composed of solution tank, metering pump, filter, safety valve, check valve, pressure gauge, buffer tank, liquid level gauge, control cabinet, etc., which are installed on one base. The user only needs to place the combined dosing device in the dosing room, connect the water inlet and the drug outlet and connect the power supply to start and put into operation. This factory integrated device can greatly reduce the workload of design and site construction, and provide a reliable guarantee for the quality, safety and site operation of the whole system. 　

5. Performance description:

1. The whole set of device mainly includes feeding system, storage tank, dosing system, power control system, etc.

2. The dissolving drum is equipped with level gauge, low level alarm, valve and other facilities required for automatic operation. The outer wall of the whole body is equipped with a magnetic flap liquid level gauge, which can observe the liquid level in the barrel in real time. There is a feed port and a standby port on the top of the whole body. The side of the barrel is equipped with a discharge port, a drain port, an overflow port, a liquid level gauge interface and corresponding supporting valves. When the liquid level in the barrel is lower than the set low liquid level, the alarm system will be automatically started and the dosing pump will be suspended.

3. Dosing system includes centrifugal pump, electromagnetic flowmeter and related valves.

◇ boiler water treatment system, circulating cooling system, central air conditioning circulating water system, raw water pretreatment and waste water treatment system in thermal power industry;

◇ boiler water treatment system, circulating cooling system, chemical additive dosing system, medical and electronic wastewater treatment and disinfection system in petroleum and chemical industries;

◇ disinfection of municipal water supply, swimming pool, water plant, sewage treatment and building living water;

7、 Functional features:

◇ Taking system design as the main body, it overcomes the defect of poor system of traditional products with single equipment or component as the main body;

◇ Absorb the essence of the technology at home and abroad, and make the process more optimized with the brand-new design concept.

◇ modular design of product structure, integrated combination, convenient for capacity and function expansion;

◇ according to different water quality and different requirements of users, flexible configuration of the best scheme;

◇ A variety of famous brands, different materials, various grades of equipment and components at home and abroad, users can choose any;

◇ Any choice of manual, automatic and other control methods to achieve different control requirements.

8、 Working principle:

1. The dosing device adopts the mechanical and electrical integration structure, which can be divided into fixed type and mobiles 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 frequency conversion control system, local control, remote automatic control, manual and automatic mutual 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.

2. Through different process design, the dosing device accurately configures the solution of various solid and liquid chemicals, and then uses the metering pump to accurately add, so as to meet various design requirements. Such as descaling, deaeration, coagulation, adding acid and alkali, etc.

1. The system equipment is entitled to one-year free warranty, the warranty date is calculated from the date of product acceptance, and the consumable filter material is not listed here.
2. In case of any equipment quality problem (except caused by misoperation or unforeseen factors) during the warranty period, the supplier shall repair it free of charge and replace the damaged parts.
3. After the expiration of the warranty period, only a certain material fee and appropriate technical service fee will be charged.
4. In case of system operation failure which cannot be solved by itself or by telephones, our technical maintenance personnel shall make solutions (including temporary measures) and schedule within 24 hours after receiving the written notice from the demander and report to the competent leaders of both parties.
5. After the delivery of the equipment, our company will have engineers to pay a return visit to understand the operation of the equipment and provide technical services in a timely manner. Users are welcome to ask any technical questions, and we will reply in time.
