57 A hydraulic circuit for actuating a first hydraulic motor (11.12) with an under pressure fluid, comprising an externally driven first hydraulic pump (1) for introduction of fluid into the circuit from an open reservoir (6) and a hydraulic accumulator (5) to keep the introduced body of ...
The next circuit shows an accumulator arrangement that provides high volume to move the cylinder rapidly with the relief valve set at working pressure. The accumulator and pump supply volume to fill the large bore cylinder as it extends. The cylinder then moves to working pressure while a check ...
hydraulic elevator system with closed circuit was proposed.The energy-saving principle was discussed using VVVF control,the accumulator for hydraulic ... DM Hu,B Xu,HY Yang,... - 《Journal of Zhejiang University》 被引量: 3发表: 2007年 HYDRAULIC ELEVATOR INSTALLATION ESTIMATION FOR THE WATER SO...
A hydraulic circuit includes a control valve connected to a pump, a hydraulic reservoir, hydraulic work connections and a cylinder. A controllable check valve is connected between the work connections and the control valve. An overpressure safety device is connected between each work connection the ...
to dispense with providing a low pressure accumulator with a stop valve, to remove the troublesomeness of stop valve changing over work at the every time of exchanging a working tool, and to eliminate the possibility of the occurrence of the damage of the low pressure accumulator caused by for...
发明人: 加戸 正志 摘要: PROBLEM TO BE SOLVED: To improve the service life of a die by attaching a braking accumulator to a pipe line, absorbing a surge pressure generated through braking in the final process of injection and thereby reducing impact force and impact noise.收藏...
In the fluid circuit, due to the flow of liquid, it will more or less produce pulsating impact on the equipment, and even produce stronger impact when various valves are closed and the circuit fluid changes sharply. After installing the accumulator, it can be used as a bu...
A continuously auto lifting and lowering hydraulic jack comprises a base, an oil pump, working oil cylinder, a piston, an oil box, an accumulator, a two-position and two-way valve, a dual-controlling check, a pressure-set check and other checks. The two-position and two-way valve, the...
