According to the concentration of the required medicament, a PAM dosing device is prepared in a mixing tank. After the mixer is mixed, the dispenser is placed in the solution tank, and a metering pump (addition pump) is used to deliver the prepared solution to the dispensing point. The device has the characteristics of compact structure, simple safety, convenient operation and the like. The PAM dosing device can also design and configure components according to the requirements of different process flows of users to achieve suitable functions (such as automatic remote control).

     Maintenance of PAM dosing device

     1. The pipeline of the PAM dosing device should be kept clear. Check the device, filter, feed inlet, water outlet and other parts, and observe whether there is sediment in these parts. If these symptoms are found, they should be cleaned up in time.

     2. Regularly check whether the metering pump inlet is blocked, and clean the pipes and filters regularly to avoid blockage.

     3. Regularly check the mixing device, observe whether the stirring shaft is flexible, the impeller is deformed, and the coupling is loose. If damage occurs, it should be replaced in time to make the shaft torque excessive and consume the stirring power.

     4. Regularly check the safety valve, pressure gauge and pipeline valve to avoid leakage. The standby pump should be used alternately with the pump to avoid long-term use or stopping the same pump.
