Liquid Ring Vacuum Pump Filter Replacement Method

After long-term use of the liquid ring vacuum pump, in order to prevent clogging, it is necessary to replace the filter element in a timely manner. If it is not replaced for a long time, it will cause the equipment to not play its normal use effect. When replacing the filter element To pay attention to the mastery of the method, the Liquid Ring Vacuum Pump Manufacturer will introduce the method of filter replacement.

1. How to use and maintain the replacement of the filter element of the liquid ring vacuum pump In order to ensure product quality and maintain the safe operation of the production equipment, the replacement of the pump filter element should be completed in detail according to the steps. The production operator should record and supervise the replacement process. After receiving the instruction to replace the pump filter element, first determine that the system is out of operation, prepare a suitable spare filter element, check whether the specifications, material, size, O-ring material, model and other data of the filter element are normal, and prepare tools for disassembly, collection bucket, rag, etc.

2. Clean the filter cartridge shell, empty the filter, and leave the operation area. Bring protective equipment. Disconnect the filter that needs to be replaced from the system. Slowly open the exhaust port at the top of the filter to relieve the pressure. During the process, pay attention to safety to prevent materials or liquid from splashing. Empty the filter material, open the filter cover with a tool, remove the liquid ring vacuum pump filter, and use a plastic bag The filter element is installed and ready to be scrapped. Use clean tools and rags to clean the inside of the filter and wait for a new filter element to be installed.

3. Open the plastic bag at the open end of the filter element, check whether the O-ring is intact and in place, install the material inflow according to the method of inflow from the outside of the filter element and outflow from the inside of the filter element; use a suitable wetting agent (such as water) Wet the O-ring and the cartridge seat jack, hold the end of the filter cartridge close to the O-ring, and vertically insert the filter cartridge socket into the cartridge cartridge jack. After inserting the pump cartridge, remove the filter bag and install the metal cover , Use a tool to tighten the filter; close the filter drain port, open the top vent valve of the housing, and slightly open the inlet valve to allow the material to enter the housing until the liquid overflows from the vent valve at the top of the housing, then close the vent valve. Check the dismantling place for leaks, and slowly open the filter outlet valve until it is fully opened. The replacement is complete; remove the replacement tool and cleaning tool. Clean around.

4. The Liquid Ring Vacuum Pump filter element needs special attention when performing the replacement operation: it should prevent pressure shock and prohibit reverse pressure. When the pressure drop between the upstream and downstream of the filter is greater than 0.3Mpa or the flow rate drops significantly, the replacement should be considered. Pump filter element; when installing the filter element, pay attention to the installation direction of the filter element, in and out.

The above is the method for replacing the filter element of the liquid ring vacuum pump introduced by Pressure Regulating Valve Supplier. During the replacement process, pay attention to the correct disassembly of the equipment, find the position of the filter element and replace it reasonably, so as not to damage other parts due to wrong operation After the replacement of the filter element, the equipment should be commissioned to ensure that it can be used only after it is correct.
