The automatic control system is generally composed of PLC, frequency converter, touch screen and other components. The pH value after PID operation can be stably controlled to achieve the purpose of PID operation. Each batching device is equipped with mixing system, batching system and automatic control system. The multi fixed skid is integrated into a whole, equipped with frequency conversion control system, which can realize on-site control, remote automatic control, manual automatic feeding and automatic gear shifting.
The utility model has the advantages of compact structure, small volume, low noise, stable operation, simple installation, convenient operation and use, etc. Cartridge packing machine is also called cartridge packing machine and cartridge packing machine. According to the production process, the chemical solution is injected into the complete equipment of each system. The equipment can be divided into large categories according to the application situation. The company developed and produced an automatic dosing product.
It is mainly used for the treatment of boiler feed water, circulating water, synthetic ammonia, phosphate, etc. in power plants. It can also be used in petroleum, chemical, environmental protection, water supply system and other industries. The machine adopts a combined drug delivery device, which is mainly composed of solution tank, metering pump, filter, safety valve, check valve, pressure gauge, buffer tank, liquid level gauge, control cabinet, etc., and is installed on a base.
Users only need to place the combined dosing device in the dosing room, connect the water inlet and outlet well, and connect the power supply to start to use. The complete set of factory equipment can greatly reduce the workload of design and field construction, and provide reliable guarantee for the quality, safety and field operation of the whole system. The motor of the dosage metering pump was controlled by the frequency converter, and it was found that the dosage metering pump could not work normally.
It may be that the frequency converter fails. At this time, another one (one for standby under normal conditions) should be activated and reset according to the instructions. When the material is wet and adherent during use and can not work on the surface of the level switch, the dispenser should be checked and wiped frequently (it is recommended to work once per shift).
