OHM2F—3型连杆式液压马达是日本工程船上的主要配件之一。为解决配件问题,并使我国工程船舶尽快采用这一新技术,我局机修厂在研制成功三台液压马达主要配件(活塞、活塞环、连球杆)的基础上,于1977年3月试制成功了整套液压马达样机,在超负荷(160公斤/米~2)使用的情况下,运转正常,解体后零件完好,基本符合使用要求。 OHM2F-3-link hydraulic motor is one of the main parts on the Japanese engineering ship. In order to solve the problem of fittings and to make our engineering ships use this new technology as soon as possible, our factory repaired the factory on March 3, 1977 on the basis of successfully developing the main components of three hydraulic motors (piston, piston ring and even club) Successful completion of the entire hydraulic motor prototype, overload (160 kg / m ~ 2) the use of the case, the normal operation, the disintegration of the parts intact, basically in line with the requirements.
