Installation of agricultural water-driven self-cleaning filters

The working principle of the hydraulic drive filter

Filtration process: When water flows into the filter, it first passes through a coarse filter screen and then through a finer filter medium (such as a stainless steel fine screen). These filter media can retain solid particles and suspended matter in water.

Self-cleaning mechanism: When the accumulated particles on the filter screen reach a certain amount, it will increase the pressure difference of the water flow through the filter medium. When the internal device of the filter detects that the pressure difference reaches the preset value, it will automatically start the cleaning cycle.

Backwashing: The cleaning mechanism typically involves rotating or moving nozzles that directly use part of the mainstream water or water stored in a dedicated chamber to backwash the filter screen. This backwashing removes the blockage from the filter medium.

Waste discharge: The water containing impurities released during the cleaning process will be discharged from the filtration system through the waste discharge outlet.

The main features of the hydraulic-driven filter

Energy-saving and highly efficient: Driven by water power, it does not require external power supply, reducing energy consumption and operating costs.

Continuous operation: Designed for continuous operation without human intervention, ensuring the continuity and stability of the water treatment process.

Simple maintenance: The self-cleaning mechanism reduces the need for manual cleaning, lowering maintenance costs and downtime.

Strong adaptability: It can handle water quality from various sources, including industrial circulating water, agricultural irrigation water and municipal water supply, etc.

Flexible installation: The equipment is relatively small in size and can be installed in various water systems, including horizontal or vertical pipes.

General applications of hydraulic drive filters

Industrial circulating water treatment: such as water systems for cooling towers, water for processing equipment, etc.

Agricultural irrigation: Automatically remove particulate matter from irrigation water to protect drip irrigation and sprinkler irrigation systems from clogging.

Municipal and residential water supply: Enhance the water quality and reliability of the tap water system.

Installation precautions for hydraulic-driven self-cleaning filters

Select an appropriate installation location

Ensure that the installation location is convenient for daily maintenance and inspection.

Select a location that can withstand the vibration and noise generated by the operation of the filter.

Make sure there is sufficient space at the filter installation site to facilitate future expansion or necessary maintenance work.

Pipeline configuration

Ensure that the inlet and outlet pipes are correctly connected to avoid any mismatches that may cause pressure loss and flow limitation.

Ensure that the pipe size matches the inlet and outlet sizes of the filter to maintain sufficient flow.

Use suitable pipe materials to prevent leakage caused by corrosion or wear.

Installation bracket

If the filter is not designed to be self-standing, a stable bracket should be installed. The support should be capable of bearing the weight of the filter when it is working with full water.

Direction of water flow

Ensure that the water flow direction conforms to the design of the filter. Most filters have clear markings on the direction of water flow.

System pressure and temperature

Check the working pressure and temperature of the system to ensure they are within the allowable range of the filter.

Conduct pressure tests to check the sealing performance and structural integrity of the system.

Sewage discharge facilities

Ensure that the sewage outlet is correctly connected and there are appropriate sewage facilities to facilitate the treatment of wastewater during the self-cleaning process.

Anti-freezing measures

If used in winter or in a low-temperature environment, make sure to take appropriate anti-freezing measures to prevent water from freezing inside the pipes or filters.

Debugging and operation

Before the official operation, conduct system debugging, including checking whether the self-cleaning function of the filter is operating normally.

Check for any leaks in all connections and confirm the correct Settings of all valves and control systems.

Safety and operation training

Ensure that the operators understand the working principle and operation procedures of the equipment and are familiar with the safety measures.

Hydraulic-driven self-cleaning filters are very useful in a variety of water treatment applications due to their high efficiency, energy conservation and easy maintenance. Proper installation and maintenance of such filters can significantly enhance the performance and reliability of water treatment systems.
