Embodiment Construction

[0015] An online oil flushing process for hydraulic pipelines. After the hydraulic pipelines are installed, replace the hydraulic station and control components with prefabricated pipeline diverters, disassemble the connection between the hydraulic actuator and the pipeline to be flushed, and use a hose Or temporary steel pipe connection to form a temporary oil flushing circuit, which is connected to the pre-prepared oil flushing device. The material of the temporary steel pipe forming the circuit must be the same as that of the pipeline to be flushed. After dismantling, the joints of control components and actuators are sealed with pipe caps or tapes to prevent secondary pollution. Then follow the steps below for oil flushing:

[0016] 1. Determine the flushing plan and draw a road map. In the same flushing system, the difference in diameter of the pipeline and the length difference of a single circuit are not easy to be too large. Determine the lift and flow rate of the pic...

Abstract

The invention relates to an on-line oil washing process for a hydraulic pipeline. After the hydraulic pipeline is completely mounted, a hydraulic station and a control element are replaced by prefabricated pipeline splitters; a joint of a hydraulic executing mechanism and a to-be-washed pipeline is disconnected and then is connected by a hose or a temporary steel pipe, thereby forming a temporary oil-washing loop; the temporary oil-washing loop is connected with a prepared oil-washing device; and then oil washing is carried out according to the following steps in turn: drying with nitrogen, washing with oil, checking cleanness, exhausting the wash oil, recovering the pipeline, filling working oil, and testing the pressure of the system pipeline. The on-line oil washing process is capable of reducing the repeated transportation of the pipeline and is safe and environment-friendly, simple in operation, excellent in washing effect, high in working efficiency and low in cost.

Description

Technical field: [0001] The invention relates to a hydraulic pipeline cleaning method, in particular to an online oil flushing process for hydraulic pipelines. Background technique: [0002] During the installation process of medium pipelines with high cleanliness requirements such as hydraulic systems and thin oil lubrication systems, due to the long installation period and the influence of various factors such as the external environment of the construction site, various degrees of corrosion will occur in the pipelines, resulting in It is difficult to ensure the cleanliness of the oil quality when the system oil is flushed, which may cause malfunctions. Therefore, it is necessary to use the pipeline circulation cleaning method to remove the rust in the pipeline, and then perform oil flushing to wash out various pollutants in the pipeline, so that the cleanliness of the medium in the pipeline can reach the design cleanliness standard. However, in the installation and const...
