Development of Water Hammer Recognition and energy reduced water hammer prevention system
SM Tech Co., Ltd. (CEO Cheolsoo yang) was established in 2007 as an innovative
company that develops water hammer prevention system and pumps. The
company handles from design, production, inspection, sales, education and
maintenance.
When change in fluid’s moving speed changes due to the reason of valve opening
or maneuver of pump from a pipeline, pressure wave occurs and the occurred
pressure wave is delivered through the pipeline to give damage to the pipeline and
other equipment; this is known as water hammer.
Specializing in manufacturing water hammer prevention system
The reason of water hammer is important is because the pipeline is damaged. Due
to the ascending pressure of pipeline, the pump, valve, flange, structure, and duct
become damaged. Moreover, accidents may occur due to the big shock that
occurs when recombining after separating water column due to the negative
pressure.

However, the water hammer prevention equipment was invented through the years
of experience and research/development. Not only the water level signal is
analyzed but the pressure signal is analyzed as well to operate accordingly to each
situation. Moreover, the equipment prevents operating unnecessity of discharge
solenoid valve and air compressor to acquire safety in any situation.
Also, the level transmitter that measures the water level of the pressure tank has
automatic cleaning functions to prevent breakdown. Also, it can be used in rapid
pressure change or high pressure to be applied in situations with danger in rupture or
even polluted water.
This is a function related to the operation of the facility that increases stability in
storage and prevention of malfunction, which is how the company describes.
Furthermore, the water level and pressure change are analyzed and controlled for
energy reduction, which also helps in cost reduction. SM TECH has 20 years of
computational analysis experience. The company is acknowledged for effectively
comparing and handling design of duct, selection of equipment, design of
equipment including pressure vessel, site installation, test operation, computational
analysis, and actual operation.
Achieved 57.78% Required Power Reduction compared to Existing Green Certificate
Holder
While all energy is blacked out or malfunctioning, the facility can be protected, and
appropriate maneuver is possible by recognizing the control of pump or valve to
prevent the occurrence of water hammer. Also, the maneuver preparation time for
water hammer is 0 seconds to be able to acquire safety in all water hammer
maneuver. Furthermore, the site assures safety by achieving 57.78% required power
reduction compared to existing green certificate holders.
This company made great investments in research and development to develop
new technology. Moreover the company trains professional technicians to increase
the quality in product development, design, and construction. The company has
been acknowledged for technical development performance including ISO
14001:2004 and ISO 9001:2008. The company also acquired Performance
Certification (Small and Medium Business Administration), Superior Product (Public
Procurement Service), Green Technology & Green Technology Product (Ministry of
Science, ICT, and Future Planning), and the company was also awarded bronze in
South Korea Water Service Technology Ceremony. The company possesses 11
patent registrations including water hammer recognition, energy reduced water
hammer prevention system, LED water level indicator for pressure tanks, and etc. Furthermore, the company possesses 10 patents for related equipment skills.
Based on the continuous research and development as well as accumulated skills,
the company is trying to develop competition in raising quality and lowering price
by establishing an organized and specialized system of technicians. Through radical
site management, the company accepts the request of clients by listening closely
and has a strategy of growing as a small but strong company by acquiring global
skills in providing the best service.

⚫ Introduction for Surge Analysis
In case of idle pump's active operation, sudden stoppage of pump due to
malfunction or blackout or at rapid valve opening, fluid inside the pipeline changes
to unsteady flow condition due to large pressure increase or decrease by rapid fluid
velocity change inside supply pipeline. At such unsteady fluid condition by sudden
change in fluid velocity, pressure shock wave travels back and forth between pipes
and inner pipeline pressure drops below water's saturated vapor pressure according
to pipeline profile to form vapor cavity and subsequently eventuate column
separation. If inner pipeline pressure falls below atmospheric pressure, pipeline
collapse can be eventuated and in case of pressure reaching beyond device's
allowed pressure limit due to high pressure generated from re-combination of vapor
cavity separated columns, there would be significant damage threats not only on
the pipelines but also on other facilities such as pumps and valves.
Such water hammer originated damage can be listed as in case of accident from
pump motor's accelerated reverse cycle due to conveying fluid's reverse flow by
sudden pump power cut off, in case of damage from pump, valve, pipeline and
subsidiary facility breakage due to pressure increase and in case of pipeline rupture
due to column re-combination at pressure normalization after pipeline collapse and
column separation according to inner pipeline pressure increase or decrease.
Recently, pump facilities are gaining their capacity and size with more complex fluid
supplying systems having large diameter and long distance pipelines where water
hammer is becoming a more serious problem. Unlike other accident causes, water
hammer originated accidents can potentially implicate damage on entire pump

facility equipment and subsequently, associated problems are regarded with more
seriousness where fundamental counter measures are greatly in requirement. In
order to soften such water hammer effects or to protect the system, review on surge
control system is required and such can be effectively reflected upon pump facility
design stage or at installation work stage through computer program aided water
hammer analysis.
This report has numerically analyzed water hammer on water shock anticipated
pipeline system of the maintenance project of WA water supply expansion as to
intend to provide sensible design data on surge control system to counter such
water hammer effects.

2-2-2 Expansion Tank
The basic operational principle of the closed expansion tank for preventing Water
hammering is the same as that of the air chamber. However, if the capacity of the
closed expansion tank is large, there exists the possibility of problems in
manufacturing and maintenance. A typical air chamber has a structure whereby air
contacts and merges with water. On the other hand, a closed. It is made of general
rubber (Butyl Rubber, EPDM). Because a hanging rubber pocket with an internal
installation structure is used, the force always acts in the direction of gravity, and the
rubber pocket can be damaged if even a bit of dust gets inside it.
If the internal rubber pocket is damaged, air may infiltrate the water, or be released
out through the pipe. If compression fluid, air or nitrogen disappears from the inside,
the closed expansion tank cannot provide any function for Water Hammering,
except in the role as a simple water tank.
However, the exterior of the closed expansion tank is generally made of steel, thus it
is difficult to determine whether the internal diaphragm is operating properly or not.
A "Safety device-equipped airtight expansion tank" has a safety device to externally
