The correct use and maintenance of automatic dosing device

- Apr 09, 2018-

The steps of using the automatic dosing device firstly require the user to configure the drug according to the ratio of the dosing solution, and accurately dosing with a metering pump. Then connect the automatic dosing device, check each flange interface and secure it to prevent fluid leakage.


After completing the connection, connect the power of the automatic dosing device. In the first step, open the control cabinet of the automatic dosing device, and connect the three-phase four-wire power cable that meets the requirements of the metering pump and the motor to the corresponding connection terminals and connect the ground cable. The second step is to start the metering pump momentarily by controlling the operation switch. Observe and measure the motor's direction of rotation. Look from the top of the motor clockwise. If the steering is correct, fix the terminal box.


In the third step, the mixer is momentarily started by controlling the operation of the automatic dosing device to observe the steering of the motor. If the steering is correct, the terminal box is fixed. If the steering is incorrect, the terminal box is fixed after adjusting the phase sequence. Finally, close the drain valve and fill the liquid container with liquid; turn on the valve of the dosing system and start the metering pump.


In order to improve the effectiveness of the automatic dosing device, the pipelines of the equipment should be kept unobstructed at all times. Check the connection points, filters, inlets, and outlets of the devices from time to time, and observe whether there are deposits at these locations. If these symptoms are found, they should be cleaned up in time.


And it is required to periodically check the stirring device of the automatic dosing device and the pipeline valves of the pressure gauge for inspection in order to avoid leakage. Note that the standby pump and the pump used for the automatic dosing unit should be used interchangeably to avoid long-term activation or deactivation of the same pump.
