Replacement Method of Liquid Ring Vacuum Pump Filter Element

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

1. How to use and maintain the liquid ring vacuum pump filter element In order to ensure product quality and maintain the safe operation of production equipment, the replacement of the pump filter element should be completed in detail according to the steps. Production operators should record and supervise the replacement process. After receiving the production instruction for replacing the pump filter element, first determine the system to stop running, 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 such as disassembly tools, collection buckets, rags, etc. 

2. Clean the casing of the filter element of the pump, and empty the area around the filter, leaving the operating area. Bring protective gear. Disconnect the filter to be replaced from the system. Slowly open the exhaust vent on the top of the filter to relieve the pressure. Pay attention to safety during the process to prevent material or liquid from splattering. Drain the material in the filter, open the filter cover with a tool, remove the liquid ring vacuum pump filter element, and use a plastic bag. The filter element is installed and discarded. Clean the inside of the filter with clean tools and rags, and install a new filter element.

3. Open the plastic bag at the open end of the filter element, check whether the O-ring is intact and in place, and install the material inflow according to the method of flowing in from the outside of the filter element and flowing out of the inside of the filter element; use a suitable wetting agent (such as water) Wet the O-ring and the socket of the filter element holder. Hold the filter element near the end of the O-ring, and insert the filter element socket completely into the filter element socket. After inserting the pump filter element, remove the filter element packaging bag, and then install the metal cover. , Use a tool to tighten the filter; close the filter drain port, open the bleed valve on the top of the housing, and slightly open the inlet valve to allow the material to enter the housing until the liquid overflows from the bleed valve on the top of the housing, and close the bleed valve. Check the disassembly for leaks, and slowly open the filter outlet valve until it is fully open. Indicates the replacement is complete; remove the replacement tools and cleaning tools. Clean the surroundings.

4. Liquid Ring Vacuum Pump filter element needs special attention during replacement operation: 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, consider replacing it. Pump filter element; when installing the filter element, pay attention to the installation direction of the filter element.

The above is the method for replacing the liquid ring vacuum pump filter element introduced by the Pressure Regulating Valve supplier. During the replacement process, pay attention to the correct disassembly of the equipment, and find the reasonable replacement of the filter element, so as to avoid incorrect operation causing other parts damage, after the replacement of the filter element, do a good job of debugging the equipment to ensure that it is correct before continuing to use.
