[0002] Regularly inspect and maintain the mud pump and other machinery, solve problems as soon as possible to avoid downtime, pay attention to the size of the mud and sand particles during construction, and check the vulnerable parts of the mud pump frequently when the particles are large, so as to repair or replace them in time. The vulnerable parts of the mud pump are mainly the pump casing, bearings, impellers, etc. Replace the mud pump filter element and filter element support net, use cold plate punching, roll the tube roll machine, weld the solder joints, clean the surface, galvanize, and use epoxy resin as the adhesive. Strictly follow the specified optimal ratio and stir well to achieve high bonding strength, corrosion resistance, anti-aging, high temperature resistance (greater than 100°C), good compatibility, and the medium is oil film bearing oil, which must have a good filtering effect. The structural integrity is good, and the filter layer, outer protective net and end cover are tightly bonded, firm and durable.

[0003] However, the current mud pump filter element adopts an integral installation structure. When local filtration is blocked, the entire mud pump outlet filter element needs to be replaced. After the mud pump outlet filter element is disassembled, the sediment in the hole is not easy to clean, and it is difficult to disassemble and replace the supporting net, filter layer and outer protective net separately, resulting in excessively high cost for replacing the mud pump outlet filter.

When the sediment at the mud pump outlet is filtered onto the lower sealing ring and the upper filter element sealing ring, the user can regularly perform maintenance and disassemble the lower sealing ring and the upper filter element sealing ring on the mud pump outlet. The notch threads and thread rings are used for thread disassembly and separation, so that the lower sealing ring and the upper filter element sealing ring can be disassembled and replaced separately. The mud pump filter element adopts a split installation structure. When the local filter is blocked, the lower sealing ring and the upper filter element sealing ring can be disassembled. After the mud pump outlet filter element is disassembled, the sediment in the hole can be cleaned.
