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:
The present invention relates to a kind of conduit under fluid pressure cleaning method, particularly a kind of online oil flushing technology of conduit under fluid pressure.
Background technology:
In the medium pipeline installation process that cleannes such as hydraulic system, oil lubricating system are had relatively high expectations; Often because the influence of various factors such as length and job site external environment condition of installation period; Can produce corrosion in various degree in the pipeline, cause when system oil wash, to be difficult to its oily cleanliness factor of assurance and to cause fault.Therefore, must utilize pipeline wash cycles method to remove the corrosion in the pipeline, carry out oil flushing then all contaminations in the pipeline is developed, make the cleannes of pipeline internal medium reach the cleannes standard of design.Yet in the conduit under fluid pressure installation, how high-quality and efficient completion is constructed at present, how to guarantee that the effect of the online oil flushing of conduit under fluid pressure and quality are the technical barriers of puzzlement unit in charge of construction always.
Summary of the invention:
The object of the invention just is to provide a kind of online oil flushing technology of conduit under fluid pressure, and this technological operation is simple, developing result good, work efficiency is high, cost is low.
As above design, technical scheme of the present invention is: a kind of online oil flushing technology of conduit under fluid pressure is characterized in that: after conduit under fluid pressure installs; Hydraulic Station, control element are replaced with the pipeline diverter of making in advance; Hydraulic actuating mechanism is taken apart with treating the junction of flushing line, connects with flexible pipe or interim steel pipe, constitutes interim oil flushing loop; Be connected with preprepared oil flushing equipment, carry out oil flushing according to the following step then;
(1), must or not have oily anhydrous compressed air with nitrogen before the oil flushing and dry up pipeline, purge finish after, can begin oil flushing;
(2), before the oil flushing, fuel tank is cleaned out, through the oil strain dolly flushing oil is injected in the fuel tank then;
(3), according to the flushing accuracy class requirement of system, rationally select the filter core of filter for use, should first coarse filtration during flushing, smart again filter;
(4), the pressure reduction before and after the regular check filter, when pressure reduction surpassed setting, the reply filter core cleaned or changes, and was failure to actuate for a long time as crossing pressure reduction, check whether correct or breakdown filter core is installed;
(5), in flushing process, to note adjusting at any time the pressure and the flow of pump; Under the prerequisite that guarantees flushing pressure and flow, wash continuously more than 24 hours, could begin sampling for the first time; When not meeting quality requirement; Continue flushing, whenever once at a distance from sampling in 6 hours, till conforming to quality requirements;
(6), sampling is responsible for by the special messenger, is sent to testing agency's check of specialty after the sampling bottle sampling immediately, through check reach qualified after, flushing can stop;
(7), after oil flushing finishes, drain the fluid in the system, remove temporarily and take over, change the interface sealing, the recovery system original state adds the hydraulic oil of production run with nitrogen.
The steel pipe material in above-mentioned interim oil flushing loop needs and treats that the flushing line material is identical.
Above-mentioned flushing oil adopts the flushing oil product with hydraulic work system oil phase same model.
Advantage of the present invention is: when flushing liquid was in turbulent condition, the fluid micellar motion was randomness.The transmission of momentum, heat and the quality that causes owing to this random motion makes the turbulent flow of fluid better the pollutant that is adsorbed on inner-walls of duct to be suspended and finally take away through circulating.Therefore, the present invention can reduce pipeline repeat carrying, safety and environmental protection, simple to operate, developing result good, work efficiency is high, cost is low.
The specific embodiment:
A kind of online oil flushing technology of conduit under fluid pressure; After conduit under fluid pressure installs, Hydraulic Station, control element are replaced with the pipeline diverter of making in advance, hydraulic actuating mechanism is taken apart with treating the junction of flushing line; Connect with flexible pipe or interim steel pipe; Constitute interim oil flushing loop, be connected, form the temporary steel tubing matter in loop and need and treat that the flushing line material is identical with preprepared oil flushing equipment.Each interface of control element after splitting out, executing agency etc. is with pipe cap or adhesive tape shutoff, to prevent secondary pollution.Carry out oil flushing according to the following step then:
1, confirm the flushing scheme, drawing path figure, in the same rinse-system, pipeline diameter is poor, single loop length difference is difficult for excessive.According to the path profile of having drawn, confirm the lift and the flow of pickling machine.
2, for preventing that residual acid solution from causing emulsification, dilution to hydraulic oil, must or not have oily anhydrous compressed air with nitrogen before the oil flushing and dry up pipeline, after purging finishes, can begin oil flushing.
3, before the oil flushing, fuel tank is cleaned out, through the oil strain dolly flushing oil is injected in the fuel tank then.Flushing oil adopts the flushing oil product with hydraulic work system oil phase same model.The oil temperature will be controlled in the scope of instructions for use.
4, based on the flushing accuracy class requirement of system, rationally select the filter core of filter for use, should first coarse filtration during flushing, smart again filter.The filtering accuracy of filter core should be higher than the precision prescribed of system.
5, the pressure reduction before and after the regular check filter, when pressure reduction surpassed setting, the reply filter core cleaned or changes, and was failure to actuate for a long time as crossing pressure reduction, check whether correct or breakdown filter core is installed.
6, in flushing process, to note adjusting at any time the pressure and the flow of pump.Under the prerequisite that guarantees flushing pressure and flow, generally to wash continuously more than 24 hours, could begin sampling for the first time, when not meeting quality requirement, continue flushing, whenever once at a distance from sampling in 6 hours, till conforming to quality requirements.
7, sampling is responsible for by the special messenger, is sent to testing agency's check of specialty after the sampling bottle sampling immediately.Through the check reach qualified after, flushing can stop.
8, after the oil flushing end, drain the fluid in the system, remove temporarily and take over, change the interface sealing, recovery system original state, the hydraulic oil of adding production run with nitrogen.
