Embodiment Construction

[0011] The method for selecting a hydraulic power source of a hydraulic system according to an embodiment of the present invention, the main steps of which include:

[0012] (1) Firstly, the working medium of the hydraulic system is provided by the hydraulic source, and the throttling speed control system uses a quantitative pump to supply oil. The oil supply of the hydraulic pump is greater than the oil demand of the system, and the excess oil flows back to the oil tank through the overflow valve. The relief valve also plays the role of controlling and stabilizing the oil source pressure;

[0013] (2) The volumetric speed control system adopts variable pump oil supply, and the maximum pressure of the system is limited by the safety valve. The oil supply volume of the hydraulic pump matches the required flow rate of the system. In each stage of the working cycle, multiple pumps are used for oil supply;

[0014] (3) An accumulator is added as an auxiliary oil source, and a coar...

Abstract

The invention discloses a method for selecting a hydraulic power source of a hydraulic system. The method comprises the following steps that firstly, a working medium of the hydraulic system is supplied by the hydraulic source, a throttle speed adjusting system is supplied with hydraulic fluid by a quantitative pump, the hydraulic fluid supply quantity of a hydraulic pump is greater than the quantity of hydraulic fluid required by the system, and the excessive redundant hydraulic fluid flows back to a hydraulic tank through an overflow valve; a volume speed adjusting system is supplied with hydraulic fluid by a variable pump, the maximum pressure of the system is limited by a safety valve, the hydraulic fluid supply quantity of the hydraulic pump is matched with the quantity of hydraulic fluid required by the system, and in each phase of work circulation, the hydraulic fluid is supplied by multiple pumps; an accumulator is additionally arranged and is used as an auxiliary hydraulic source, an inlet of the pump is provided with a coarse filter, and according to the requirements of protected elements, the hydraulic fluid entering the system is subjected to secondary filtration by a corresponding fine filter; and a magnetic filter is arranged on a hydraulic circuit, and according to the environments of the hydraulic equipment and the requirements of on temperature raising, the heating and cooling measures are additionally carried out. The method has the beneficial effects that the running precision of the machine is favorably improved, the abrasion is reduced, the service life is prolonged, the force on 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 selecting a hydraulic power source 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 design, it must...
