China Construction Machinery Information

Guide: a few days ago, the full hydraulic control reversing hydraulic system of concrete machinery pumping mechanism independently developed by Shanghai Hongdeli Heavy Industry Co., Ltd., a member of Liugong group, was successfully trial produced and applied for a number of national patents. At present, the prototype starts the stopwatch of the experimental machine in construction 2.1. The construction site has passed 300 hours of work and the power has been turned on. If there is no dynamic operation test, the test results meet the expectations

recently, the full hydraulic control reversing hydraulic system for concrete machinery pumping mechanism independently developed by Shanghai Hongdeli Heavy Industry Co., Ltd., a member of Liugong group, was successfully trial produced, and a number of national patents were applied. At present, the prototype has passed 300 hours of industrial test on the construction site, the test results have reached the expected design goals, and the performance indicators are excellent

it is reported that during the development of the system, the targeted hydraulic simulation and optimization design of Hongdeli heavy industry has effectively obtained the heat source of the system, reduced the heating problem of the large flow hydraulic system, and made the full power of the oil pump fully applied to pumping. The directional valve is directly driven by differential pressure feedback, which not only achieves the timely matching and efficient response of pumping and distribution actions, but also significantly reduces the failure rate of electrical components

at present, the peers who widely use the controlled or electronically controlled reversing technology in the industry using the liquid medium thick steel plate products are generally troubled by the heating problem of the large flow hydraulic system, and often adopt the methods of cooling the main circuit and increasing the power of the cooler. This practice, on the one hand, sacrifices part of the power; On the other hand, the main circuit pressure impact increases the risk of cooler burst. The successful trial production of the full hydraulic control reversing system of Hongdeli heavy industry has not only solved the heating problem of the large flow hydraulic system in the pumping process, but also maximized the power of the concrete machinery Jinan Shijin automobile interior material testing machine and improved the overall safety. It is a successful practice of liugonghongdeli on the pumping technology
