What is the function of a piston?
It is the moving component that is contained by a cylinder and is
made gas-tight by piston rings. In an engine, its purpose is to
transfer force from expanding gas in the cylinder to the crankshaft
via a piston rod and/or connecting rod.
Hydraulic breaker piston
The piston material is SNCM616V,SNCM26V 20Cr2Ni4A,GCr15,40CrNiMo,
the hardness of heat treatment is HRC58-62, and the surface
roughness Ra value after fine grinding is ≤0.2μm. processed by
machining center with high inner and outer precision. Multiple heat
treatment to ensure the rigidity. The piston can be also
customized.
Can hydraulic pistons be repaired?
The good news is that in many cases, a hydraulic cylinder can be
repaired rather than replaced. However, the extent of the damage
will determine whether repair is feasible.
DOPRO is a professional manufacturer committed to the design and
production of Hydraulic Breaker and Attachments Whether your job is
breaking down concrete surfaces, trenching, or preventing blockage
in crushing systems, DOPRO is made to withstand continuous breaking
in harsh environments. We DOPRO use only high quality low materials
to produce superior product and all the manufacturing process such
as heat treatment, forging, machining, grinding and ets, are
strictly controlled by qualitied and experienced engineers in our
factory with computerized and latest facilities. All parts are
thoroughly inspected at every time that each process such as
cutting, heat treatment, machining, grinding, cleaning, assembly,
etc. is carried out, and all inspection data per each production
lot are maintained and controlled so as to be utilized as data for
better qualities and performance improvement. Major parts such as
piston cylinder and etc are designed for outstanding durability
through structure analyses, and mass production is started only
when a proto type has been completely
