Description
Technical field
The present invention relates to hydraulic tubing, particularly relate to a kind of hydraulic tubing method of construction.
Background technique
Hydraulic transmission is the most conventional a kind of power system in the present age, and it has the advantages such as stable drive, reliable, long service life.But hydraulic element have very strict requirement to pipe cleanness, the hydraulic tubing of having constructed for scene need rinse, if pipeline does not carry out surface treatment in a pre-installation, then need before flushing first to carry out pickling (containing degreasing, pickling, passivation three processes), to reach the cleanliness of designing requirement to pipeline.After flushing is qualified, also need before coming into operation to carry out pressure test.Therefore, in existing hydraulic tubing construction, the technique of line treatment is first pickling, rinses, finally carries out pressure test.
The pickling of hydraulic tubing, flushing, these working procedures of pressure test are directly connected to the progress and cost that hydraulic tubing installs.In the construction of existing hydraulic tubing, for realizing carrying out pickling and flushing to hydraulic tubing, interim loop need be made, comprising and hydraulic system supervisor is connected with pickler, flushing device; Make collector and replace valve platform, pipeline before and after valve platform is carried out connected sum control (because valve platform can not participate in pickling and first oil flushing); Flexible pipe is adopted to carry out ring head at the place of actuator of pipe end.For avoid loop repeat make, pickling and rinse often use the same circuit, therefore require that the pipe in interim loop, pipe fitting, valve all need acidproof, oil resistant.Because valve platform does not participate in first oil flushing, need when first oil flushing to remove, then need valve platform to reset when essence is rushed, participate in essence punching, but general valve platform can not participate in again the pressure test of pipeline, if so after completing flushing (containing just punching, essence punching), after need carrying out valve platform, pipeline pressure is tested, valve platform need be removed by again, reconnects temporary pressure test loop, intricate operation.If the pipeline in addition after valve platform needs to suppress, the pipe in that interim loop, pipe fitting, valve also need to be high pressure.The making in interim loop is a very large input, the particularly interim loop of acidproof, oil resistant, high pressure, for large-scale rolling line, namely luminescent material buying expenses reaches tens up to a million, loop also because the instrument of specialty need be adopted to cut, hole, beat groove, welding and extend 50% production time.Again because the hydraulic system in each engineering is all not identical, the not reproducible utilization in interim loop of making, so owner, construction party are all the method for construction that employing expense is few, the time is short as far as possible.
In existing hydraulic tubing construction, for pickling and flushing, employing be make the loop matched with flushing pressure, the material that the material making interim loop is then selected according to hydraulic system is determined; Pipeline pressure is tested, then for saving engineering time and expense, just suppress for the supervisor before valve platform.The shortcoming of existing method of construction is the not reproducible utilization of material making loop, time particularly for interim loop employing stainless steel, drops into a lot of human and material resources, time, an engineering uses, is namely abandoned, cause the huge wasting of resources.In addition, every engineering all needs the interim loop of field fabrication, which increases the engineering time of pipeline.Adopt and only pressure test is carried out to supervisor before valve platform, lacked the test to the withstand voltage situation of pipeline after valve platform, then, when test run and hydraulic system life's work, pipeline leakage of oil or explosion may have been occurred, there is potential safety hazard.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of hydraulic tubing pickling, flushing, pressure test monolithic construction method.Present invention achieves hydraulic tubing pickling, flushing, pressure test integral construction efficient, economical.
In order to solve the problems of the technologies described above, a kind of hydraulic tubing pickling, flushing, pressure test monolithic construction method, it comprises:
Step one, make interim loop, this interim loop comprises pickling flush equipment, and this equipment is by the main pipeline of diameter-variable connector access oil hydraulic circuit, the valve platform place installation of modular collector Quick Connect Kit of pressure test can not participated in, and after valve platform pipe with hose loop head;
Step 2, the hydraulic line system that can participate in pressure test for valve platform is carried out continuously according to following order: pipeline uniform compression test before and after pickling → flushing → valve platform;
The hydraulic line system that can not participate in pressure test for valve platform is carried out continuously according to following order: pipeline uniform compression test → essence punching before and after pickling → first oil flushing → valve platform.
Described a kind of hydraulic tubing pickling, flushing, pressure test monolithic construction method, described modularization collector Quick Connect Kit comprises:
Supervisor's cross-over sub, its one end is connected with supervisor before valve platform;
The modular type collector of one group of end-to-end, one end is connected on supervisor's cross-over sub, and the other end is closed, and each modular type collector is provided with the valvular arm of band;
Quick-replaceable flexible pipe, its one end connects a described tube end;
Crossover sub, its end is connected on the other end of quick-replaceable flexible pipe, and its other end is connected with pipeline to be rinsed, and crossover sub comprises helical, SAE flange type, method flange-type three kinds of forms.
The interim loop that fast connecting device of pipelines in the present invention makes, can realize making once interim loop, meet the requirement of pickling, flushing, pressure test three operations.Modularization collector Quick Connect Kit achieves pickling, Rinsing unit is connected with the quick of pipeline main pipeline to be rinsed; Achieve the quick connection of pipeline before and after valve platform place valve platform; It once drops into, reuse; Economize on resources, reduce costs; Easy accessibility, to save time; Highly versatile, is applicable to various hydraulic system.Simultaneously. the present invention adopts new line treatment technique, and before and after achieving valve platform, pipeline is suppressed simultaneously, after avoiding valve platform pipeline do not suppress pipeline before and after brought potential safety hazard and valve platform separately suppress the operation brought loaded down with trivial details and drop into increase; Adopt pipeline unification before and after valve platform to carry out pressure test, the processing time of pipeline pressure test can be shortened.To sum up, present invention achieves hydraulic tubing pickling, flushing, pressure test integral construction efficient, economical.
