Ceramic cylinder liner is the key component of the mud pump, due to the cylinder liner in the high pressure for a long time in the relative reciprocating movement, so the cylinder liner is the mud pump wear parts. The traditional cylinder liner is made of metal materials, poor wear resistance, short service life. Ceramic cylinder liner can improve its performance.
Increase the life span 5-10 times than metal cylinder liner;
Have the advantages of wear-resistant, corrosion-resistant, high-pressure-resistant, high-temperature-resistant, high-strength and high-hardness;
Reduce the transportation cost, maintenance cost, labor cost, storage cost, etc. of drilling work;
Ceramic cylinder liner has more toughness, longer service life, saves lubrication water and reduces piston wear.
