Wholesale factory manufacturing crane parts Hydraulic Buffer
Hydraulic shock absorber1.Application HY series hydraulic buffers
are identified by high capacity, remarkable buffering effect and
outstanding absorption efficiency. This series of buffer is able to
reduce the inertia impact between two moving objects or between a
moving object and stationary object. This series of buffer is
designed for the applications in heavy duty machinery such as
material handling machinery, metallurgical machinery and railway
industry machinery. It will provide excellent damping stop effect
for these machines to avoiding inertial impact during
travel.2.Working Principal With the benefit of the specially
designed damping holes, which are arranged in a specific layout, HY
serial buffers provide a stable damping force during the whole
buffering process. This will ensure the impacting object will be
retarded smoothly. The majority part of the energy generated during
the impacting process will be absorbed. Thus, almost no rebound
force will occur on the impacted object. This will avoid heavy
shock load on the buffer shaft. 3.Installation GuideThis type of
buffer shall be installed horizontally. And it shall be installed
in accordance with the instruction symbol on the base plate (the
indication hole on base plate shall be in upper position.) •In case
the installation position has to be changed due to the actual
working conditions, the damping performance will be greatly
reduced. •The working temperature covers from ‐25°C‐80°C. In case
the working temperature is below •‐25°C to ‐45°C, please specify
when placing an order. •Considering the working conditions, the
hydraulic oil used for this buffer shall be abrasion proof and
pressure‐proof, at least 20# pressure‐proof oil shall be used. •The
oil volume added inside oil reservoir shall be correct. The
suitable volume shall be the oil level just overflowing the piston.
•The misalignment angle shall be less than 1° during installation
•The selection of buffers shall be in accordance with the impact
force of the running trolley. •We can provide specially designed
products upon our clients' requirement. capability kN/m
