Problems solved by technology

When the pressure of the flushing oil and the pipeline are reduced to a certain extent, the state of the fluid in the pipe is no longer in a state of turbulent flow, resulting in that the pipeline with a smaller diameter cannot achieve the purpose of oil flushing and cannot meet the quality requirements of oil flushing

Abstract

The invention relates to hydraulic systems, in particular to a bidirectional oil flushing device of a hydraulic system. The bidirectional oil flushing device of the hydraulic system comprises an oil tank. The outlet and the inlet of the oil tank are connected with a pump and a filter respectively, the inlet with the filter is connected with a small-pipe-diameter pipeline of a flushing line through a second valve, and the outlet with the pump is connected with a large-pipe-diameter pipeline of the flushing line through a fourth valve; the outlet of the second valve is communicated with the outlet of the fourth valve through a pipeline with a first valve, and the inlet of the second valve is communicated with the inlet of the fourth valve through a pipeline with a third valve. The bidirectional oil flushing device effectively flushes the whole oil flushing loop, improves oil flushing quality of a hydraulic lubrication system, shortens oil flushing time of a hydraulic lubrication pipeline and achieves a good flushing effect.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a hydraulic system oil flushing device. Background technique [0002] The rapid development of hydraulic lubrication system has made hydraulic lubrication equipment widely used in all walks of life, especially in modern large-scale production lines, its advantages are more fully reflected, but correspondingly, the oil of hydraulic lubrication pipeline system is required to be clean put forward higher requirements. Oil flushing of the hydraulic lubrication system is a key process to ensure the normal operation of the system, and it is also a necessary process before system commissioning. The main purpose of system oil flushing is to remove the pollution latent in the system during the process of system production and installation, mainly including solid particles such as cutting, burrs, molding sand, paint, abrasives, welding slag, rust flakes and dust, so as to ensure the cleanliness of the...
