Problems solved by technology

[0004] Since the above-mentioned hydraulic system only plays the role of cooling and filtering hydraulic oil, and the capacity of the oil tank is large, it takes a lot of time to replenish a large amount of oil with a general oil filter trolley, and each hydraulic station needs to be equipped with a dedicated oil filter trolley. Increase equipment cost

Abstract

The embodiment of the invention discloses a hydraulic system. The hydraulic system comprises a circulating pump, an electric motor, an oil tank, a cooling system, a filter and an accumulator component, wherein the circulating pump is connected with the electric motor, the oil inlet of the circulating pump is connected with the oil outlet of the oil tank, the oil outlet of the circulating pump is connected with the oil inlet of the cooling system; the oil outlet of the cooling system is connected with the oil inlet of the filter; the oil outlet of the filter is connected with the oil inlet of the oil tank; the oil tank is connected with the accumulator component; and the oil outlet of the oil tank is also provided with an oil feeding pipeline; and the oil feeding pipeline is provided with a first control valve. In the embodiment of the invention, the original pipeline is directly improved and the oil feeding pipeline is additionally arranged at the oil inlet of the oil tank, thus oil can be directly fed through the oil feeding pipeline and the oil filtration trolley is not required. Therefore, the hydraulic station does not require the oil feeding trolley, and the cost of a single oil feeding pipeline is far lower than that of the oil feeding trolley, thus the cost of the equipment can be reduced.

Description

technical field [0001] The invention relates to the field of steel rolling, and more particularly, to a hydraulic system on a rolling line. Background technique [0002] At present, the hydraulic system on the steel rolling production line has the following characteristics: long pipeline, large pipe diameter, high system pressure; large oil tank volume, large oil consumption. Such as figure 1 Shown is a cooling and filtering system in a hydraulic system on a traditional rolling line. The system includes: a circulation pump 12 , a motor 13 , an oil tank 11 , a cooling system 14 and a filter 15 . Wherein, the motor 13 is connected with the circulation pump 12, the oil inlet of the circulation pump 12 is connected with the oil outlet of the oil tank 11 through a pipeline, and the oil outlet of the circulation pump 12 is connected with the oil inlet of the cooling system 14 through a pipeline, and the cooling The oil outlet of the system 14 is connected with the oil inlet of t...
