Does the filter device of a water jet loom need to be replaced after a long period of use?

The filtering device of the water jet loom needs to be replaced after a long period of use, which is a necessary measure to ensure the normal operation of the equipment and maintain the quality of the water jet. The following is a breakdown explanation:

1. Decreased filtering effect
As the usage time increases, the filter element inside the filter will reduce its filtering capacity due to sediment blockage.
Unable to effectively intercept impurities such as sediment and rust in water, it can easily cause nozzle blockage and fabric pollution.

2. Structural aging or damage
The material of the filter screen and filter element may corrode, rupture, and deform if immersed in water for a long time.
Once damaged, impurities will directly enter the water spray system, affecting weaving stability.

3. Affects the uniformity and pressure of water spray
Blocked or deteriorated filtering devices can lead to weakened water flow or unstable flow rate, uneven nozzle spraying, and insufficient pressure.
This will affect the effect of weft yarn introduction and even lead to fabric defects.

4. Increased burden on water pumps and systems
When the blockage is severe, the water pump needs more power to push the water flow, which may lead to overload, increased energy consumption, and shortened service life of the water pump.
Replacing filters can reduce system burden and improve overall operational efficiency.

5. Regular replacement is a requirement of maintenance standards
Most equipment manufacturers recommend regularly replacing filters based on usage time or operating water volume (e.g. every 3-6 months).
Even if the surface is not completely blocked, the internal structure may still affect performance due to micro cracks or scaling.

6. Determine the timing of replacement based on the cleaning situation
If the frequency of filter cleaning increases, impurities accumulate severely, and there is still no significant improvement after cleaning, it indicates the need for replacement.
Can establish filter maintenance records, grasp the usage cycle and optimal replacement time.
