First，Filtration operation and precautions of stainless steel bag filter
The stainless steel bag filter is easy to operate. When using, just install the filter bag of the required fineness grade in the filter cartridge, check whether the O-ring seal is in good condition, and then tighten the ring bolt of the filter cartridge cover, and then it can be put into work.
After the pump is started, the pressure gauge on the filter rises slightly, and the initial pressure is about 0.05MPa. With the extension of the use time, the filter residue in the cylinder gradually increases. When the pressure reaches 0.4MPa, the cylinder cover should be stopped and opened to check the residue left in the filter bag. If necessary, the filter bag can be replaced and continue to be used (the filter bag can generally be reused by cleaning).
The filter pressure is generally adjusted to 0.1-0.3MPa. It can be adjusted through the return line or the return valve on the pump. If the filter pressure is too high, the filter bag and the protection net will be damaged, so special attention should be paid.
Second，When to replace the filter bag of the stainless steel bag filter
1. Roughly determine the time to replace the filter bag according to experience.
2. Pressure gauges are installed on the inlet and outlet pipes of the bag filter. The time to replace the filter bag is determined by the pressure difference displayed by the front and rear pressure gauges. Generally, the pressure difference that the filter bag can withstand is 0.5~1kg/cm2 When the pressure difference reaches this range, the filter bag should be replaced in time to avoid rupture of the filter bag in the bag filter, which will affect the filtering effect of the bag filter.
