1. External conditions
The PAM dosing device is a fully automatic dissolving and dosing device, and the equipment body consists of the machine itself, piping system, automatic system, and steel structure. The equipment must be placed indoors to minimize rain and sun exposure. The purpose of preventing rain is to prevent the dry powder dosing machine (a fixed amount of PAM dry powder can be transported, due to the special physical and chemical properties of PAM dry powder, which should not be damp); the main transportation configuration of the pipeline system The water required for PAM solution and the configured solution to be transported. The pipeline system cannot be operated at low temperature and high temperature for a long time. It is easy to cause freezing and cracking of the pipeline and premature aging caused by long-term exposure. PAM adds The medicine device must be placed in an indoor environment to avoid freezing and cracking and aging of the pipeline system caused by overcooling or overheating.
2. External conditions
a. In the water inlet pipeline, an external wire interface is reserved on the body of the dosing device. The on-site water supply should be 2.5~3.5bar, and the water volume should be sufficient;
b. Dosing pipeline, the dosing device has reserved external wire interface, only need to connect here to the dosing point on site;
c. For overflow and venting pipelines, connect these two pipelines to the discharge port (trench or other) on site.
d. For the power source (power source), just connect the power line to the electric control cabinet of the dosing device on site. The internal control of the dosing device is a self-contained system, and the internal wiring has been completed when the equipment leaves the factory.
