Liner

Liner

1. The liner It is petroleum drilling mud pump core pressure-bearing liner component the exterior is made of a steel shell inner hole with ceramic/bimetal wear-resistant coating it is installed inside the hydraulic cylinder of the mud pump as a piston cylindrical chamber with reciprocating motion it is a key and vulnerable component of the drilling pump adaptive various standard drilling mud pump models specify the specifications of the SC series according to the inner diameter

   

2. Depend on the hard inner wall of the cylinder liner forms a sealed pressure-bearing cavity the piston of the mud pump is in the cylinder liner undergoes reciprocating linear motion within the piston moves forward to squeeze the drilling mud inside the chamber establish high pressure transport the mud to the drill pipe when the piston returns, it sucks in fresh mud the wear-resistant layer inside the cylinder liner resists the sand particles in the mud the scouring and friction of rock debris the outer steel structure is subjected to high-pressure pumping reduce medium wear the structure bears the two types of loads separately ensure that the pump body can maintain a stable working pressure for a long time
3. The liner first, compare the pump model select the corresponding inner diameter cylinder liner clean the installation position of the hydraulic cylinder of the slurry pump press the cylinder liner smoothly into the liquid cylinder chamber assemble the sealing ring and fix both ends install the piston assembly after adding the lubricating medium, conduct the test run check the concentricity of the inner hole and ensure there is no leakage of the seal monitoring the wear amount of cylinder liners in daily operations grooves appear on the inner wall and out-of-round and stop the machine and disassemble for replacement when there is leakage during the installation process, avoid any bumps or knocks to the inner surface of the ceramic prevent the cracking and failure of the wear-resistant layer

   

4. Mainly used for oil and gas drilling operations non-excavation horizontal directional drilling machine-mounted mud pump adaptive mining exploration grouting pump for well drilling as the fluid flow cavity carrying high-pressure mud for circulation transportation provide pressure channels for the drilling circulation system resist the erosion caused by slurry containing solid particles ensure that the mud pump can continuously output high-pressure drilling fluid cooling drill bit carry the rock fragments back with you it is an indispensable wear-resistant and pressure-bearing component of the drilling mud circulation system
5. The liner is the ceramic lining has extremely high hardness resistant to mud slurry erosion the wear resistance is far superior to that of ordinary bimetal cylinder liners the service life can be increased by several times the outer steel cylinder has strong compressive strength capable of withstanding the high-pressure conditions of drilling operations standardization of specifications easy to disassemble, assemble and replace adaptive mainstream imports domestic mud pump the inner wall has a high degree of smoothness the flow resistance of the mud is low can reduce the energy consumption of the pump body overall reduction in frequent equipment shutdowns and component replacements reduce the operating and maintenance costs of drilling operations
