Abstract

The invention discloses a speed adjusting method of a hydraulic system transmission mechanism, and the speed adjusting method is characterized by comprising the following steps of installing and determining a hydraulic actuation element, adopting a reversing valve or a logic control unit to control the direction, and adopting a logical combination structure of a cartridge valve and a pilot control valve; adopting a quantitative pump to supply oil, utilizing a flow control valve to change the flow inputting or outputting from the hydraulic actuation element to adjust the speed, and adjusting the speed by changing the displacement of a hydraulic pump or a hydraulic motor; a variable pump is used for supplying the oil in the volume throttling speed adjusting process, utilizing the flow control valve to adjust the flow inputted into or outputted from the hydraulic actuation element, ensuring the oil supply quantity to be equivalent to the oil demand quantity, and determining a circulating form of a loop; and adopting an open circulating way to make the hydraulic pump suck oil from an oil tank, and returning the pressure oil back to the oil tank after releasing the energy through the system. The method has the beneficial effects that different technique requirements of a pressing workpiece can be completely and accurately satisfied, the movement precision of the machine is improved, the abrasion situation is reduced, the service life is prolonged, and the stress of the machine body is assisted.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to a speed regulating method of a transmission mechanism of a hydraulic system. 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. The hydraulic transmission system is an integral part of hydraulic machinery. The design of the hydraulic transmission system should be carried out at the same time as the overall design of the main engine. When starting the d...
