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.

CEO Cheolsoo Yang stated, "While contributing in energy reduction and stability, we

will release environment-friendly products with less carbon emission." Yang further

stated, "With Korea's best water hammer prevention equipment technology, we

have been focusing on research and development every year to be leading in the

area."

He continued, "Products that assure safety must be supplied for free unless it is the

best. We will assure the safety of the global market with Korea's skills and products

⚫ 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

monitor the internal diaphragm and ensure safe operation.
