The Sucking Type Self-Cleaning Filter operates on an advanced principle that combines suction and backwashing to ensure efficient filtration and self-cleaning. Here's a detailed explanation of its working mechanism.


  1. Filtration Phase: When the fluid enters the filter, it is directed towards the inner side of the filter screen. The impurities in the fluid are trapped on the inner surface of the filter screen, while the clean fluid passes through the filter screen and out of the filter outlet.

  2. Pressure Differential Detection and Backwash initiation: Over time, as the impurities accumulate on the inner surface of the filter screen, a pressure differential is created across the screen. Once this pressure differential reaches a preset value, the backwash cycle is automatically initiated. Alternatively, the backwash cycle can also be initiated at preset time intervals.

  3. Backwash Phase: During the backwash phase, the backwash valve is opened. The pressure differential between the internal pressure of the filter and the atmospheric pressure drives a portion of the fluid in reverse through the filter screen. This backwash fluid is directed through a suction scanner that is rotated by a motor. The suction scanner has multiple nozzles that create a high-velocity backwash flow, effectively sucking off the impurities from the inner surface of the filter screen.

  4. Discharge Phase: The impurities removed from the filter screen are discharged out of the filter through the backwash valve. The backwash process is carried out during normal filtration, ensuring uninterrupted operation of the filter.

  5. End of Backwash Cycle: Once the backwash cycle is completed, the backwash valve is closed, and the filter returns to normal filtration mode.


This innovative working principle of the Sucking Type Self-Cleaning Filter ensures high filtration efficiency and reduces maintenance requirements by automating the cleaning process. The filter can operate continuously, providing clean and safe fluid for various applications.

Pressure differential detection, also known as differential pressure sensing, is a crucial component in the operation of many filtration systems, including the Sucking Type Self-Cleaning Filter. Here's a detailed explanation of how it works:


The principle of pressure differential detection is based on measuring the difference in pressure between two points in a system. In the context of a filtration system, these two points are typically the inlet and outlet of the filter.


When the filter is clean, the pressure difference between the inlet and outlet is relatively small. This is because the fluid can flow freely through the filter screen, with minimal resistance to its flow.


As the filter screen accumulates impurities over time, the flow of fluid through the screen becomes more restricted. This increases the resistance to flow, which in turn increases the pressure at the inlet of the filter. Conversely, the pressure at the outlet of the filter decreases due to the reduced fluid flow.


This creates a pressure differential across the filter screen. The pressure differential can be detected using a pressure differential sensor, which is typically a part of the filter system. The sensor can be calibrated to trigger a signal when the pressure differential reaches a certain threshold. This signal can then be used to initiate the backwash cycle of the filter.


In essence, pressure differential detection works as an indicator of the filter's cleanliness. It provides a reliable and automated method to determine when the filter needs cleaning, thereby enhancing the efficiency and longevity of the filter system.

The Sucking Type Self-Cleaning Filter is a complex system made up of several integral components, each serving a specific function to ensure efficient filtration and self-cleaning. Here's a detailed breakdown of its structure and the role of each component:


  1. Filter Housing: This is the main body of the filter where the filtration and backwash processes occur. It is typically made of robust materials like stainless steel to withstand high pressure and corrosive fluids.

  2. Filter Screen: This is the core component where the actual filtration takes place. The fluid flows from the inside to the outside of the filter screen, leaving the impurities trapped on its inner surface.

  3. Inlet and Outlet Ports: These are the entry and exit points for the fluid. The inlet port directs the fluid towards the inner side of the filter screen, while the clean fluid exits the filter through the outlet port.

  4. Backwash Valve: This valve opens to initiate the backwash phase. It allows a portion of the fluid to flow in reverse through the filter screen, removing the impurities from its surface.

  5. Suction Scanner: This is a key component in the self-cleaning process. The scanner, equipped with multiple nozzles, moves in a spiral path along the inner surface of the filter screen during the backwash phase. The high-velocity backwash flow through the nozzles effectively sucks off the accumulated impurities.

  6. Motor: This powers the movement of the suction scanner during the backwash phase. It ensures the scanner covers the entire inner surface of the filter screen.

  7. Pressure Differential Sensor: This sensor detects the pressure differential across the filter screen. When the pressure differential reaches a preset value, indicating the filter screen is sufficiently blocked with impurities, the sensor triggers the start of the backwash cycle.

  8. Controller: This is the 'brain' of the filter. It receives the signal from the pressure differential sensor and controls the opening and closing of the backwash valve, as well as the operation of the motor. It ensures the filter operates in a fully automated manner, maximizing efficiency and minimizing manual intervention.


Through the coordinated operation of these components, the Sucking Type Self-Cleaning Filter achieves high filtration efficiency and automated self-cleaning, ensuring a continuous supply of clean fluid for various applications.

Ensuring the stability of a filter during operation involves several key steps:


  1. Regular Maintenance: Regular inspection and maintenance of the filter components are crucial. This includes checking for leaks, assessing the condition of the filter screen, and ensuring the proper functioning of the backwash valve, suction scanner, motor, and pressure differential sensor.

  2. Proper Installation: The filter should be installed correctly, following the manufacturer's guidelines. Improper installation can lead to operational instability and reduced filtration efficiency.

  3. Monitoring Pressure Differential: The pressure differential across the filter screen should be monitored closely. If the pressure differential becomes too high, it could indicate a blockage in the filter screen, which could destabilize the filter operation.

  4. Automated Control: Utilizing an automated control system can greatly enhance the stability of the filter. The controller can automatically initiate the backwash cycle based on the pressure differential, ensuring timely cleaning of the filter screen and preventing excessive pressure buildup.

  5. Using Quality Fluids: The quality of the fluid being filtered can also affect the stability of the filter. Fluids with high levels of impurities can clog the filter screen quickly, leading to instability. Therefore, pre-treatment of the fluid to remove large impurities can be beneficial.

  6. Appropriate Sizing: The filter should be appropriately sized for its intended application. A filter that is too small may become overloaded, leading to instability, while a filter that is too large may not operate efficiently.


By following these steps, the stability of a filter during operation can be ensured, leading to efficient filtration and a longer lifespan for the filter.
