Self-Cleaning Working Principle
The filtration process begins when water enters the filter housing and passes through the stainless steel filter screen. Suspended particles are retained on the inner surface of the screen, while filtered water continues through the outlet.
During operation, the system monitors pressure differences between the inlet and outlet sides. When accumulated particles cause the pressure difference to reach the preset value, the cleaning cycle starts automatically.
The cleaning process includes:
This process allows the filtration system to continue operating while cleaning is performed.
System Structure & Main Components
The filtration unit consists of several components that work together to maintain continuous filtration performance.
Filter Housing
The housing provides structural support for internal filtration components and is available with material options according to application requirements.
Stainless Steel Filter Screen
The filter screen is the core filtration element responsible for particle separation. Different opening sizes can be selected based on water quality and filtration requirements.
Cleaning Mechanism
The internal cleaning system removes particles accumulated on the screen surface through mechanical movement.
Differential Pressure Controller
The controller monitors pressure changes and sends signals to activate the cleaning cycle.
Drainage System
The drainage outlet removes collected contaminants during the cleaning process.
Automatic Control System
The control system allows operators to manage filtration conditions according to actual process requirements. Available control functions may include:
For projects requiring integrated industrial control, customized PLC configurations can be considered according to system requirements.
Filter Screen Options
Different filter screen configurations can be selected according to liquid characteristics and filtration targets. Available options include:
Stainless Steel Filter Screen
Suitable for applications requiring corrosion resistance and repeated cleaning cycles.
Different Filtration Ratings
Filter opening sizes can be configured according to particle removal requirements, flow conditions, and process standards.
Material Selection
Stainless steel grades and component materials can be selected based on water composition, operating temperature, and installation environment.
