Ebara Engineering Review presents research, technical advancements, and new products in easy to understand terms. In particular, some long pipeline systems have high risk for Water Hammer. Therefore, Water Hammer Analysis is required in the system design to avoid damages of pipeline system. Computational Fluid Dynamics CFD analysis on the Pumping Station Design Design of intake channels and suction pits in the pumping stations must be suitable for reliable and efficient pump operation.

The high suction performance required for cryogenic pumps directly leads to the economical effciency of LNG transportation. Pump cavitation deteriorates the suction performance of pumps and causes unstable operation.

Ebara designs reliable pumps with high suction performance by using cutting-edge cavitation CFD and optimization based on the 3D inverse design method.

Materials Corrosion Protection Seawater is used at many facilities, including desalination plants and power plants that use large amounts of cooling water. However, stainless steel and other materials corrode in seawater. Ebara has extensive knowledge and experience in dealing with the causes of corrosion, e.

Thus, we can ensure the stable pumping of seawater through the proper selection of materials, cathodic corrosion protection, BEM-based corrosion prediction analysis, the development of duplex stainless steel fabricated pumps, etc. These pumps are currently in operation at various facilities using large amounts of seawater. Sand Erosion Protection Repetitive collisions between sand from the water with the surface of the impeller and other pump internal components causes erosion during pumping.

In addition to the use of hard materials, Ebara ensures stable pump operation through erosion rate prediction and erosion protection, such as the spraying of coating containing ceramic. Injection Pumps As carbon capture and storage CCS is gaining increasing attention as a measure against global warming, there are high expectations for injection pumps to inject liquefied carbon dioxide into the ground.

Bearings for safe and stable pump operation under high-pressure conditions and seal technology to prevent external leakage of acid gas are also important. Plants of semiconductor and display require our pumps to function without fail 24 hours a day, days a year. In addition, saving energy demands such as the power consumption reduction increase as well as pumping performance enhancement for the pump. Ebara works closely with clients to develop and deliver products that achieve efficiency and energy goals that match your needs.

Semiconductor manufacturing equipment, which require completely dust free environments, need to be installed in a clean room with high-performance air conditioning systems.

A clean room can be costly to maintain according to size. Therefore, it is important for our dry vacuum pumps to be small foot print. We have developed pumps with smaller instrumentation and improved layouts that reduce your footprint beyond expectations. The semiconductor device is realized by forming thin film of insulating material and conductive material on the surface of wafer with the use of a dedicated device and processing it into a fine circuit. In this process, however, the surface of the circuit becomes uneven.

The CMP system turns it into a flat surface with roughness in the range of 10 to 20nm, which is equivalent to irregularity of 0. With such high-accuracy planarization, we can laminate more than ten layers of fine circuits and thereby realize the high-level circuit integration of semiconductor devices. The CMP system polishes a rotating wafer by pressing it on a rotating table attached with resin sheet, while pouring polishing liquid that contains fine abrasive grains and chemical solution.

Cryogenic Pumps (Ebara)

Handlevognen er tom Cryogenic Pumps Ebara Cryodynamics division of Ebara International Corporation is the recognized world leader in the engineering and production of specialized cryogenic liquefied gas pumps and turbine expanders. All the equipment produced utilizes submerged electric motors or generators, thus eliminating any rotating sealing system. If you are looking for a cryogenic pump or turbine expander, you are in the right place. In-Tank Retractable ECR Type This unique design allows the pump to be installed inside a storage tank in a vertical pump column, with a suction foot valve located at the bottom. Because the pump is installed through the top of the tank, all connections below the maximum liquid level of the tank can be eliminated. This eliminates the possibility of major tank leakage due to a pipe or connection problem.
