Summary of Dosing Pumps
Edit:Lianyungang Mi Lu Luo Pump Industry Co., Ltd   UpDate:2017-05-08

Dosing pump, the use of sensor signal control dosing pump work process, this control method need to use pH meter, conductivity meter and other monitoring instruments and the corresponding sensor. First, according to the operation of the system need to set the control parameters (pH or conductivity) of the limit, if the system during the operation of the following circumstances the dosing device that began to work: If the pH value is lower or higher than the set value. PH is low, indicating that acid is too strong, the system has a tendency to corrosion; pH is high, indicating that alkaline is too strong, the system has a tendency to fouling. At this time the detection instrument will feedback the signal to the control system, the control system and then output instructions to the specified metering pump, so that it opens the dosing system to adjust the pH value, until the pH returned to normal, the metering pump closed. If the conductivity is higher than the set value, indicating that the system exceeded the amount of salt, corrosion fouling tendencies. At this time the monitoring instrument will feedback the signal to the control system, the control system and then output instructions to the sewage solenoid valve, so that the solenoid valve to open the drainage, to be conductive back to normal, the solenoid valve closed. And then metering the pump to open the dosing, supplement the loss of the loss of pharmaceutical agents, the system's drug content maintained at a normal level, added to the specified time metering pump closed.
Overview of Dosing Pumps
Automatic dosing devices in the power, oil, chemical, metallurgical industry, environmental engineering, water treatment and other fields often need to be a certain kind of liquid continuously into another liquid into a mixture, or to join the pharmaceutical and liquid In the presence of a component of the chemical reaction to achieve the desired process requirements. In order to achieve the best results, in the case of changes in the conditions of the chemical dose of the automatic tracking control dosing speed, so in the automatic dosing device, we use the advanced automatic control to control the dosage.
Dosing pump device This dosing device has a simple structure and easy installation. Automatic dosing equipment mainly by the measuring box (medicine tank), dosing pump (dosing pump), automatic control system, connecting piping and other components of the automatic dosing device. Automatic dosing device in addition to part of the dosing pipeline, sampling piping and dosing concentration detection instrument, these devices are generally concentrated in a dosing room, automatic dosing device metering box, metering pump, automatic control system , That is installed on a base. The manufacturer can complete the equipment purchase, manufacture, assembly, commissioning, commissioning, the user only need to combine the automatic dosing device placed in the dosing, the dosing pump and dosing pipe, measuring box import and export Water pipes and other connections, and the control cabinet power and test instrument signal can be sent to the control cabinet can be put into operation. This can greatly reduce the on-site construction workload, to avoid the numerous links between the numerous leads to the error and the passing between each other, effectively guarantee the duration and project quality, reduce the user's trouble and loss.
Second, the dosage metering pump device type and structure
Dosing metering pump device is a dual pump single control combination, three pump dual control combination, combined furnace R value automatic control device and several types, each type of structure is somewhat different, the following are described separately.
1, double pump single control combination automatic dosing device The device consists of a measurement box, two dosing metering pump (each other), a set of AC variable frequency automatic dosing control system, connecting pipelines, valves, base, etc. Composition, see Figure 1. The volume of the measuring box is 1M '(the user has special requirements), whether with the stirrer, remote level gauge, liquid level alarm and tank material selection by the user or design department, but also by the user directly to me Unit consultation. Tank material is steel, stainless steel, lined with plastic body, for different liquid. When ordering, you must specify the following parameters: flow (1 / H), pump outlet pressure (MPa), pump flow material (or the name and concentration of the delivery agent). , The use of sensor signals to control the process of dosing pump, this control method requires pH meter, conductivity meter and other monitoring instruments and the corresponding sensor. First, according to the operation of the system need to set the control parameters (pH or conductivity) of the limit, if the system during the operation of the following circumstances the dosing device that began to work: If the pH value is lower or higher than the set value.
