Rolling mill hydraulic pipeline cleaning device

Abstract

The invention discloses a rolling mill hydraulic pipeline cleaning device. The rolling mill hydraulic pipeline cleaning device comprises a liquid storage tank, a hydraulic oil tank and a cleaning pump, a liquid inlet of the cleaning pump is connected with the liquid storage tank, a liquid outlet of the cleaning pump is provided with a liquid conveying pipe which can be connected with a to-be-cleaned hydraulic pipeline, the liquid storage tank is provided with a liquid return pipe which can be connected with the to-be-cleaned hydraulic pipeline, the cleaning pump comprises a shell, an elastic pipe arranged in the shell and a plurality of extrusion heads, the extrusion heads are connected with a piston rod of an oil cylinder so that the extrusion heads can move vertically relative to the elastic pipe, each extrusion head has an extrusion position where the extrusion head is attached to the elastic pipe and a releasing position where the extrusion head is away from the elastic pipe, and the oil cylinder is connected with a hydraulic pump through an electrically controlled main reversing valve so that each extrusion head can stretch out and retract in sequence according to certain interval time. According to the rolling mill hydraulic pipeline cleaning device, the cleaning efficiency can be remarkably improved, secondary pollution is avoided, automatic collection of hydraulic oil can be achieved, and then the accuracy of cleanliness detection of the hydraulic oil can be improved.

Description

technical field [0001] The invention relates to an auxiliary device of a hydraulic system of metallurgical equipment, in particular to a cleaning device for a rolling mill hydraulic pipeline. Background technique [0002] In modern metallurgical equipment, more and more hydraulic drives are used, and in hydraulic systems, the cleanliness requirements for hydraulic oil are also getting higher and higher. Specifically, the hydraulic system includes a hydraulic station, hydraulic control elements, hydraulic actuators and hydraulic pipelines. In order to ensure the good operation of the hydraulic system, it is usually necessary to maintain the cleanliness of the hydraulic oil in the hydraulic system between NAS4 and NAS7. We know that after the hydraulic system works for a certain period of time, various components of the hydraulic system, especially the hydraulic pipeline, will produce some fine particles, which will reduce the cleanliness of the originally clean hydraulic oil...
