Practical Power Launches New Marine Hydraulic Drive Products

Author:

At the recently held 11th China Dalian International Maritime Exhibition, Practical Power Group (China) Industrial Co., Ltd. launched two new hydraulic products aimed at China’s shipbuilding industry: an integrated electro-hydraulic actuator and a combined multi-way hydraulic power unit. It is reported that the integrated electro-hydraulic actuator is powered by either AC or DC motors, which drive hydraulic pumps and cylinders to generate linear motion. The motor’s rotation enables both extension and retraction functions, with a maximum output force ranging from 2.5 to 165 kilonewtons. The combined multi-way hydraulic power unit is primarily driven by an AC motor, while a DC motor, a backup pump, and a manual pump are used as emergency power sources.
　　At the recently held 11th China Dalian International Maritime Exhibition, Practical Power Group (China) Industrial Co., Ltd. launched two new hydraulic products—integrated electro-hydraulic actuators and combined multi-way hydraulic power units—targeted at China’s shipbuilding industry.
 
　　It is understood that the integrated electro-hydraulic actuator is powered by either an AC or DC motor. The motor drives a hydraulic pump and cylinder to generate linear motion, with the motor’s direction of rotation enabling both the extension and retraction functions. The actuator’s output force ranges from 2.5 to 165 kilonewtons. In combination multi-way hydraulic power units, the primary power source is provided by an AC motor, while a DC motor, a backup pump, and a manual pump serve as emergency systems. When the motor acts as the primary power source, its direction of rotation reverses the flow direction of the hydraulic fluid; in manual mode, the direction of hydraulic fluid flow is controlled by a directional control valve on the manual pump. These two new marine hydraulic drive products adopt a modular design, integrating the motor, pump, valves, cylinders, and oil tank into a single unit. All components are manufactured and assembled using high-reliability, high-standard processing and assembly techniques. According to Practical Power (China) Co., Ltd., these two products were originally developed based on the roof-opening and closing systems used in high-end convertible cars. They feature reliable performance and can meet maintenance-free requirements for up to 10 years.
 
　　According to reports, integrated electro-hydraulic actuators and combined multi-channel hydraulic power units began entering the Chinese market at the end of 2012 and were first adopted by Wuxi Dongzhou Marine Accessories Co., Ltd. in May 2013. According to Wu Haiba, Technical Director of Watertight Door Products at Dongzhou Marine Accessories, these two product types are compact in size and do not require any piping installation by shipyards, making commissioning and installation both convenient and quick, thereby reducing maintenance costs for both shipyards and shipowners. After adopting these two product types, the company has reduced the installation and commissioning time for watertight doors from the previous three to four days to just one or two days today. The amount of hydraulic oil required per watertight door has also been cut from the previous 100 liters down to only 2 to 3 liters now, and there is no longer any leakage of hydraulic oil. Currently, Dongzhou Marine Accessories’ products—including hydraulic sliding watertight doors and hydraulic hinged watertight doors—equipped with integrated electro-hydraulic actuators have obtained relevant national patents. At the 2013 China International Maritime Technology Academic Conference and Exhibition, as well as at the 2014 Singapore Maritime Exhibition and the Hamburg Maritime Exhibition in Germany, these products received unanimous recognition from both domestic and international shipowners.
 
　　Hydraulic components are core parts of deck machinery as well as ship fittings such as doors and windows. Due to the lack of a relatively comprehensive global after-sales service network for core components, many domestically produced ship equipment products—including deck machinery—often find it difficult to gain acceptance among overseas users. Wu Haiba believes that the two product models launched by Practical Power (China) Company not only help elevate the technological level of watertight doors, windows, and other related products but also facilitate the entry of domestically manufactured marine equipment into overseas markets. He pointed out that the parent company of Practical Power (China), Practical Power Group, is listed on the New York Stock Exchange in the United States. As a diversified multinational group, Practical Power Group operates in more than 30 countries worldwide and boasts a well-established global after-sales service network, fully capable of assuming the responsibility of providing global after-sales support for its Chinese subsidiary’s products.
