METHOD, APPARATUS AND ITS CONSTRUCTIONAL MEMBERS FOR COMBINED COMPLEX PROTECTION OF OIL-GAS PUMPING SYSTEM EMPLOYED ON PERMAFROST, MARSHY, GULF AND WEAKLY DEVELOPED UNFIXED GROUNDS FROM TECHNOGENIC INTERNAL AND EXTERNAL VIBRATORY AND ALTERNATING CYCLIC CLIMATIC-GEOLOGIC EFFECTS

摘要

FIELD: construction of pipeline systems. SUBSTANCE: method involves collecting initial data; calculating optimal parameters; providing test checking and correction of constructional designs for vibratory and compensatory protection of power transmission, supporting and constructional joint members of system. Joint members are made in the form of elastic multiple-layer reinforced branch pipes and positioned at pipeline and pump junction sites, inside pipeline upstream and downstream of portions subjected to external and internal vibratory effects. Power transmission members are made in the form of high-elasticity profiled couplings providing controlled rigidity of torque transmission. Supporting members are made in the form of elastic pneumatic shock-absorbers of low and/or high load-bearing capacity. Said members are positioned after making calculation allowing center of inertia of each aggregated power unit of system and total center of rigidity of vibratory-compensatory supporting shock-absorbers to be determined, with alignment of said centers being indispensable condition. EFFECT: increased efficiency and enhanced reliability in operation. 3 cl, 7 dwg
