1. Triplex mud pump liner(Ceramics Cylinder Sleeve ):
product introduce and advantage
Our ceramic liners combine the strength of a forged steel outer
shell with the abrasion and corrosion resistance of a ceramic inner
sleeve. We provide Zirconia(ZrO3) Sleeves as wellas Alumina(Al2
O3.) sleeves., of which Zirconia exhibits better impact strength,
higher hardness and be honed to finer surface finishes thanalumina.
Ceramic liners are currently thepremium liner offered today.
Ceramic liners have been known to operate well overthe 7000-hour
work. Due to the high hardness of the ceramic surface, they
wearsubstantially less than other liner types. This translates into
longer pistonoperating times. If the correct conditions are
present, the cost per operatinghour can be much less than that of
the other liner types

3. API Std. Mud Pump Liner for Oil Drilling:
A cylinder liner ( or cylinder sleeve) is a cylindrical part to be
fitted into an engine block to form a cylinder. It is one of the
most important functional parts to make up the interior of an
engine. Our products after quenching technology for the surface and
heat treating, the forged liner is with high intensity, strong
tenacity and wearability. Main functions as belows:
(1) Formation of sliding surface:
The cylinder liner, serving as the inner wall of a cylinder, forms
a sliding surface for the piston rings while retaining the
lubricant within. The most important function of cylinder liners is
the excellent characteristic as sliding surface and these four
necessary points.1) Less wear on the cylinder liner itself2) Less
wear on the partner piston ring 3) Less consumption of lubricant
(2) Heat transfer:
The cylinder liner receives combustion heat through the piston and
piston rings and transmits the heat to the coolant.
(3) High temperature and high pressure:
A cylinder wall in an engine is under high temperature and high
pressure, with the piston and piston rings sliding at high speeds.
In particular, since longer service life is required of engines,
forging cylinder that have excellent wear-resistant properties are
only used for cylinder parts.

2. Features of Mud pump Liners:
Liners are the main damageable parts in mud pumps for development
drilling. The ceramic liner (zirconium and other compound
materials) has the features of long service life time,
wear-resistance and erosion-resistance. Its average life time
ismore 5 times longer than the metal cylinder. Honestly, its own
weak point is that there could be some fracture when the ceramic
cylinder is impacted violently by other object. To guarantee the
safe operation of the components and avoid breaking the ceramic
liners, the following safety guidelines should be noted before
(1) When installing the cylinder, it is better to use the special
tool or follow the instruction below;
(2)Strictly prohibit flinging knocking or impacting the cylinder,
if you need to put down, you shouldmove it as slowly and careful as
(3) Strictly prohibit hitting ceramic cylinder with hammer or other
heavy objects (including the metal shuck of the cylinder). When
hitting, wood or other materials should be used asbuffer cushion;
(4) When you use hammer orother heavy objects to hit or strike the
cylinder (especially for pressure cap,piston crown, piston rod),
you should control the appreciated angle and force.Otherwise, the
impact force which has been transferred to the cylinder
willpossible fracture the ceramic liner of cylinder;
(5) Before the installationofpiston, you should check whether there
is any damage on the metal shuck ofpiston crown. There should be at
least 0.20mm installation clearance between themaximum outer
diameter of the piston and inner diameter of ceramic
liner,otherwise, ceramic liner could possible be damaged;
(6) After the installation,the side-friction between the metal part
of piston and ceramic wall of thecylinder should be avoided. If it
does happen, you should rectify as quickly asyou can
