Dosing device

product description

As the precise metering and dosing of fluids, the dosing device is responsible for the adding tasks of strong corrosiveness, toxicity and high viscosity during the process. At the same time, it has flexible and diverse control modes, which can easily form various controls with the host computer system. Loop to achieve more complex and precise process control. The dosing device of Yongli Environmental Protection Equipment Co., Ltd. is divided into two parts from the internal function: the dispensing part and the dosing part. The dispensing part mainly includes the electric stirring solution tank, and the dosing part mainly includes the dosing pump, which is used as the dosing part. As the key actuator metering pump, our company selects high-quality imported products (Prominent, Pasfida, Milton Roy), or domestic metering pumps according to customer requirements. The design, manufacture and acceptance of the dosing device comply with "Dosing Device for Water Treatment" (HJ/T369-2007), JB2932-1999 "Technical Conditions for Water Treatment Equipment Manufacturing" and other relevant standards. The main models include: one box, one pump Units, one tank with two pumps unit, two tanks with two pumps unit, two tanks with three pumps unit, each unit can be arranged separately or in combination.

Features

■ Diversified structure: The simple type realizes simple quantitative chemical dosing by directly installing the metering pump on the chemical container, with simple operation and saving installation space. The basic type is an open frame type dosing control system, and the necessary accessories can be selected to meet more precise metering requirements. The intelligent dosing control system can realize fixed-proportion online open-loop control, closed-loop automatic control, and real-time communication with the host computer; ■ Flexible configuration: according to different metering requirements, single box and single pump , Double tanks, double pumps and multiple tanks and multiple pump system configurations can be selected; in the double pump and multiple pump systems, the metering flow and output pressure of each pump can be selected according to specific working conditions. ■ Scope of the factory: single pump system adding flow rate and working pressure range up to 10.000Lh and 3000bar; ■ powerful: system function configuration is flexible, you can choose quantitative addition, feedforward proportional addition, feedback type set concentration range addition and pre Feedback + feedback type setting concentration range addition and other methods are optional; ■ Abundant accessories: you can choose the special anti-corrosion material and structure of the container according to the specific situation of the user, or equip the relevant pipeline pump valve accessories and spare parts, such as safety Valves, check valves, buffers, flow monitors, injection valves, etc.; ■ After-sales service: The dosing control system can be designed according to user needs, and the operators are trained and guided in detail during the equipment debugging stage; ■ The process is mature and reliable

Function Description

The dosing unit ensures that it can meet the system's continuous dosing and operation requirements for the dosing amount. The complete process system can meet the control requirements and water quality control requirements; the provided control cabinet can accept control instructions from other control systems and send dry contact signals Carrying out remote monitoring input, the number of output signals can meet the monitoring and control requirements of the dosing system in the water area control system. The flow rate of the metering pump is adjusted manually (frequency conversion) under the power frequency to realize the dosing. The dosing system equipment is equipped The non-optimal switching function between local/remote control operation modes, the capacity of the dosing equipment can meet the needs of the dosing amount under various operating conditions such as normal system operation, startup and system failure operation. The priority of the control mode: on-site Control takes precedence over remote control.
