The precautions for using vertical self-cleaning filters mainly include the following aspects:
I. Installation Precautions
Space Reservation: Sufficient space (such as 0.6 meters) should be left around the filter during installation to facilitate subsequent maintenance work.
Water Flow Direction: Pipes should be connected according to the arrow direction indicated on the filter body to ensure that the water flow direction is consistent with the arrow direction and must not be reversed.
Drain Valve Configuration: If the filter is equipped with a hydraulic control valve, a drainage pipeline should be configured at the outlet of the hydraulic control valve. The drainage pipeline should not be too long, generally not exceeding 10 meters, and should be securely connected.
Installation Location: The filter should be installed before the water-using equipment that needs protection and as close to the water-using equipment as possible. Especially in power systems, it should be installed between the water pump and the water-using equipment.
Safety of Electrical Control Equipment: As the equipment is electrically controlled, it should be ensured that the installation environment has safe power supply facilities, and the electrical control device should be kept in a dry state to prevent electric shock and short circuits.
Specification Matching: The specifications of the filter should match the pipeline or flow rate. When a single filter cannot meet the system flow rate requirements, multiple filters can be considered for parallel installation.
II. Operation Precautions
First-time Operation Check: Before the first operation, check whether the connections of the filter are secure, whether the electrical control box is dry, and manually operate the drainage and cleaning functions to ensure the normal operation of the equipment.
Control Mode Selection: Select the appropriate control mode (manual control or automatic control) according to actual needs and correctly set parameters such as filtration time and drainage time.
Differential Pressure Monitoring: In automatic control mode, close attention should be paid to the set value of the differential pressure switch and the actual differential pressure situation to ensure that the equipment operates normally within the set differential pressure range.
Regular Maintenance: Regularly maintain and service the filter, including cleaning the filter screen, checking the wear of the electric brush and drain valve, etc., to ensure the long-term stable operation of the equipment.
III. Safety Precautions
Waterproof and Rainproof Measures: When installing outdoors, attention should be paid to waterproof and rainproof measures to prevent the equipment from being dampened or flooded, which may cause short circuits or damage.
Power-off Operation: When performing maintenance or repairs, the power should be cut off first and a warning sign should be hung. Operations should only be carried out after ensuring safety.
Emergency Handling: During use, if equipment failures or abnormalities are encountered, the equipment should be immediately stopped and professional personnel should be notified for inspection and repair.
In summary, when using vertical self-cleaning filters, strict adherence to the precautions related to installation, operation, and safety should be observed to ensure the normal operation and long-term stability of the equipment.
