Method for increasing energy utilization rate of hydraulic system in field of ship building

Abstract

The invention discloses a method for increasing the energy utilization rate of a hydraulic system in the field of ship building. In the aspect of operation, a piston type main work cylinder is arranged for hydraulic press and return; a floating ejector cylinder is arranged for reversely pulling a hydraulic flange and respectively carrying out micro adjustment operation, manual operation and semiautomatic operation; in the aspect of travel speed, the assisting time is saved by quick idle running motion and a pressure-maintaining and time-delaying system is required to be arranged so as to meet the specific process requirement; the pressure of work fluid is maintained at 25-30MPa or a lower work pressure value or higher work pressure value of an interval is selected according to the difference of unit deformation pressure of a workpiece; the a hydraulic pressure is subjected to pressure classification; and finally, pressure pre-relieving is carried out on the main cylinder so as to reduce the impact vibration during return. The method disclosed by the invention has the beneficial effects that due to the adoption of the mode, various process requirements of pressed workpieces can be met comprehensively and accurately, the improvement of the motion precision of the machine and the reduction of wear conditions are facilitated, the service life can be prolonged, the stress of the machine body is assisted and the like.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a method for improving the energy utilization rate of a hydraulic system in the shipbuilding field. Background technique [0002] The hydraulic system has the advantages of large power, good adjustability of working pressure and flow, and heat can be brought back to the oil tank. The hydraulic system device can generate more power than other devices. Under the same power, the hydraulic device is small in size, Light weight, high power density, and compact structure; at the same time, the hydraulic device works relatively smoothly. Due to light weight, small inertia, and quick response, the hydraulic device is easy to achieve quick start, braking and frequent reversing. With the continuous development of my country's industry and science and technology, hydraulic transmission technology has been more and more widely used in the automobile industry, shipbuilding industry, power ...
