Filter bag replacement cycle:
The replacement cycle of the filter bag is not fixed, it is affected by a variety of factors, including the nature of the filter medium, filtration accuracy requirements, the nature of the treatment fluid (such as temperature, pressure, concentration, viscosity, etc.), the use of the environment (such as temperature, humidity, corrosion) and operating conditions (such as flow rate, pressure difference, etc.).
In general, the manufacturer will provide a general replacement cycle recommendation based on the design and experimental data of the product, but this recommendation is for reference only. In practical applications, it is necessary to monitor and adjust according to specific conditions.
In order to ensure the filtration effect and the stable operation of the system, it is recommended to regularly check and record the use of the filter bag, including pressure difference changes, filtration efficiency, etc., in order to discover and replace the aging filter bag in time.
How to tell if a replacement is needed:
Observe the change of pressure difference: During the use of the filter bag, the internal and external pressure difference will gradually increase with the accumulation of the filter. When the pressure difference reaches a certain level, it indicates that the filter bag has been blocked seriously and needs to be replaced. Specific pressure difference threshold
It should be determined according to the actual situation and system design.
Check the filtration effect: If the quality of the filtered fluid significantly decreases, such as increased turbidity, increased impurity content, etc., it may be that the filter bag has failed and needs to be replaced.
Observe the appearance change: If the filter bag surface damage, deformation or color change and other abnormal conditions, it may also be a signal that needs to be replaced.
Follow the use time: Even if the pressure difference and filtration effect have not yet reached the replacement standard, the filter bag has been used for a long time (such as exceeding the replacement cycle recommended by the manufacturer), it should be considered for replacement to avoid potential risks.
In summary, the replacement cycle of the filter bag needs to be judged and adjusted according to the actual situation, and the relevant parameters need to be regularly monitored and recorded in order to discover and replace the aging filter bag in time.
