The bag filter is used during the process until the treated water enters the body of the device directly from the water inlet, so that impurities in the water are deposited in the stainless steel filter, thereby creating a pressure difference. Through differential pressure switch monitoring inlet and outlet differential pressure changes, when the pressure difference reaches the set value, the electronic controller to the hydraulic control valve, drive motor signal.
The motor of the bag filter will drive the brush to rotate to a certain extent. When the filter is used, the filter element will be cleaned. At the same time as the use of the filter, the control valve will be opened for sewage. The entire cleaning process only lasts for tens of seconds. When the cleaning is finished, the control valve is closed, the motor stops rotating, the system returns to its initial state, and it starts to enter the next filtration process.
After the bag filter is installed, during the process of use, it is directly performed by a technician to set the filtration time and cleaning conversion time. The water to be treated enters the body from the water inlet, and the filter starts to work normally. When the preset cleaning time is reached, the electronic controller gives the hydraulic control valve and the drive motor signal, causing the following actions: the motor drives the brush to rotate, the filter element is cleaned, and the control valve is opened to discharge the dirt. The entire cleaning process lasts only tens of seconds. When the cleaning is finished, the control valve is closed, the motor stops rotating, the system returns to its initial state, and it starts to enter the next filtration process.
1. When the pressure is found at the outlet of the bag filter, be sure to close the output valve in time. If you do not pay attention to this, it will bring about a very bad influence.
2. When opening the vent valve, be sure to check that the bag filters have been properly connected and are properly connected. If you ignore this, then when you filter out some harmful substances, it will cause harm to the relevant staff, and it will also pollute the surrounding environment.
3. Check the pressure gauge, which is also very important.
Bag filter should pay attention to when replacing the filter bag
1. Before installing the filter bag, be sure to soak it in the pre-wetting solution for a few minutes because it is not very hydrophilic.
2. When installing, be sure to refer to the installation instructions and try not to make mistakes.
3. To test the quality of the filter. Once there is a problem with the quality of the filter, there is a problem with some part of the device. At this point, it is also important to stop operations and carry out related inspections.
