To check if the brass strainer needs to be replaced, you can follow the following steps:
Observation of filtration effect: Regularly check the filtration effect of the strainer, observe whether the effluent quality has deteriorated, such as whether there are impurities in the water, whether the color is abnormal, etc. If the effluent quality deteriorates, it may be due to internal blockage of the strainer or damage to the strainer screen, which needs to be replaced.
Check for pressure changes: If a brass strainer is installed in a piping system, the pressure changes in the piping system can be observed. If the strainer is blocked, it can cause an increase in system pressure and may even damage pipelines and equipment. If an abnormal increase in system pressure is found, it may be a signal that the strainer needs to be replaced.
Dismantling inspection: If conditions permit, the brass strainer can be dismantled regularly for inspection. After removing the strainer, observe whether the strainer screen is damaged, deformed, or severely blocked. If the strainer screen is damaged or severely blocked, it should be replaced in a timely manner.
Usage time: Based on the usage time and environment of the brass strainer, it can be roughly determined whether replacement is necessary. Generally speaking, strainers have a certain service life under normal usage conditions. If the usage time has exceeded the normal lifespan or the usage environment is harsh (such as high temperature, high pressure, high corrosiveness, etc.), it is recommended to replace the strainer.
In summary, in order to maintain the normal operation of brass strainers and extend their service life, it is recommended to conduct regular inspections and maintenance. If problems are found with the strainer or it needs to be replaced, it should be dealt with in a timely manner to avoid unnecessary damage to the pipeline system.
