Overview
Basic structure
Box body: Usually made of cast iron and carbon steel.
Filter screen/basket (Basket): There is a detachable filter basket inside, with round holes. The standard hole diameters are typically: small diameter (DN40-65) is 5mm, and large diameter (DN80 and above) is 8mm. Customization can also be done as needed, such as 3mm fine holes.
Cover plate (Cover): There is a quick-opening cover plate on the top, which is convenient for regularly removing the filter basket for cleaning and maintenance.

Daily Maintenance Quick Reference Table
| Maintenance Task | Key Actions | Recommended Frequency |
| Inspect | 1. Visual inspection: Check the body for obvious corrosion, damage, or leakage. 2. Differential pressure monitoring: Observe the readings of the pressure gauges at the inlet and outlet. A significant increase in pressure difference indicates potential clogging of the filter basket. 3. Seal inspection: Check for any medium seepage around the cover plate. | Daily or before each system operation |
| Clean | 1. Safe depressurization: Close the upstream and downstream valves of the mud box, open the venting device and drain plug to release pressure and drain the medium. 2. Open cover and remove basket: Loosen the cover nuts and vertically lift out the filter basket.3. Clean the filter basket: Use a high-pressure water gun or brush to remove debris from the filter screen, and check for any damage to the screen. 4. Reinstall and reset: Clean the inside of the body, replace the filter basket, install a new seal ring if damaged, and tighten the cover bolts in a diagonal sequence. | Routine: Every 1-3 months Condition-based: Immediately when differential pressure rises significantly |
| Replace | 1. Seals: Regularly replace the cover plate O-ring to prevent aging and leakage. 2. Corroded parts: If the body or filter basket shows severe rust, perforation, or deformation, it should be replaced entirely. | Seals: Annually or during each major overhaul Corroded parts: As per inspection findings |
Critical Maintenance Warning
Before performing any maintenance operations, ensure the piping system is fully depressurized, and the medium temperature has cooled to a safe range to prevent injury from high-temperature or high-pressure media spray. It is recommended to wear protective gloves and goggles during operations.
