Xinxiang Lifilter Brush Self - cleaning Filter is a highly efficient and intelligent filtration device widely used in various industries for fluid purification. This article will introduce its manufacturing process, installation, and debugging details.
High - quality materials are selected as the basis for manufacturing. The filter housing is usually made of corrosion - resistant materials such as stainless steel, which can ensure long - term stable operation in harsh environments. The filter screen is made of stainless steel or nylon with high - strength and fine - pore characteristics, which can accurately intercept various impurities in the fluid, from micrometer - sized particles to millimeter - sized debris.
Filter Housing: The manufacturing process of the filter housing begins with cutting the selected steel plates to the required size using plasma cutting technology. Then, the cut steel plates are processed by a plate shearing machine to make their edges smooth and meet the assembly requirements. After that, the parts are welded together to form the basic shape of the housing. Multiple welding processes are carried out to ensure the strength and airtightness of the housing. Finally, sanding and polishing treatments are performed on the surface of the housing to improve its corrosion - resistance and appearance quality.
Filter Screen: For the filter screen, precision processing equipment is used to cut and shape the stainless - steel or nylon mesh according to the design requirements. The mesh is then treated to enhance the adhesion of impurities and improve the filtering effect. Special attention is paid to the connection between the filter screen and the housing to ensure a tight fit and prevent fluid leakage.
Cleaning Components: The cleaning brush is usually made of high - quality bristles and a durable brush holder. The bristles are selected for their flexibility and toughness, which can effectively sweep the impurities on the filter screen during the cleaning process. The motor, as the power source for the cleaning process, is carefully selected for its stable performance and appropriate power output. The automatic drain valve is also an important component, which needs to be precisely processed to ensure smooth opening and closing.
During the assembly process, all components are carefully installed in accordance with strict procedures. The filter screen is accurately installed inside the housing, and the cleaning components such as the brush, motor, and drain valve are installed in their designated positions. The control box, which plays a crucial role in the operation of the filter, is also connected and integrated with other components. After assembly, a series of tests are carried out to check the integrity and functionality of the filter.
Location Selection: Choose a suitable installation location for the filter. It should be installed in a place close to the equipment that needs to be protected by filtration, and try to be close to the pressure source to avoid low - pressure problems at the inlet. At the same time, the installation site should be well - ventilated, dry, and away from potential sources of water and dust. Also, ensure that there is enough space around the filter for future maintenance and inspection. The recommended minimum distances are as follows: the net distance between devices should be no less than 1500mm, the net distance between the device and the wall should be no less than 1000mm, and a maintenance space of no less than 500mm should be left around the device.
Tool and Material Preparation: Prepare necessary installation tools, such as wrenches, pliers, and screwdrivers. Also, ensure that the connection pipes, flanges, and sealing gaskets meet the installation requirements. Check the specifications of the filter to ensure that it matches the installation pipeline. If the filter flow cannot meet the pipeline requirements, consider parallel - installing two or more filters or using side - stream filtration.
Positioning and Fixing: Place the self - cleaning filter at the designated filtering position and connect it to the inlet and outlet flanges or pipes. When connecting, pay attention to the flow direction indicated on the filter body to ensure correct installation. Use bolts and nuts to fix the filter firmly to prevent vibration and displacement during operation.
Filter Screen and Related Component Installation: Gently place the filter screen into the filter housing, ensuring that it is properly seated and sealed. Install the sealing ring into the O - ring groove. The O - ring must not be twisted or deformed to ensure a tight seal. Fix the filter screen with a filter bag pressing ring (if applicable).
Valve and Pipeline Installation: Install valves at the inlet, outlet, and drain ports of the equipment. The drain valve should preferably be a quick - acting valve. In the pipeline system, set up a bypass to ensure that the system can continue to supply water during shutdown and maintenance. Install cut - off ball valves at the inlet, outlet, and bypass of the filter. In places where backflow may occur, install a check valve at the filter outlet.
Electrical Connection: Ensure that the installation site has a three - phase 380V power frequency alternating current (three - phase four - wire system). Connect the power cord of the filter's control box according to the wiring diagram, and ensure that the connection is firm and well - insulated.
Before starting the debugging, conduct a comprehensive inspection of the filter. Check whether all components are installed correctly, whether the bolts and nuts are tightened, and whether the pipelines are connected properly without any leakage points. Inspect the electrical connections to ensure that there are no short - circuits or loose connections. Also, check the settings of the control box, such as the differential pressure threshold, cleaning time, and control mode (differential pressure control, time - based control, manual control, or PLC remote control).
Filtration Function Test: Open the inlet and outlet valves of the filter, and start the fluid supply. Observe whether the fluid flows smoothly through the filter and whether the initial pressure difference between the inlet and outlet is within the normal range. Take samples of the filtered fluid at regular intervals to check its purity and ensure that the filter can effectively intercept impurities.
Self - cleaning Function Test: Trigger the self - cleaning mechanism. You can use the differential pressure - based method by gradually increasing the impurity content in the fluid to reach the preset differential pressure value, or use the time - based method by setting a specific time for cleaning. Observe whether the motor drives the brush to rotate smoothly, whether the drain valve opens and closes properly, and whether the impurities can be effectively discharged. During the cleaning process, check whether the system continues to supply fluid without interruption.
Electrical and Control System Test: Check the operation status of the control box. Ensure that the display screen shows accurate information, and that all control buttons and switches work properly. Test the remote - control function if available to ensure seamless communication between the control terminal and the filter. Also, test the motor overload protection function by simulating an overload situation to see if the system can promptly cut off the power to protect the motor.
