PUMPING PLANT Russian patent published in 1994 - IPC

FIELD: pump engineering. SUBSTANCE: pumping plant comprises pump 1, electric motor 2 mounted on spacer 3 secured to casing of pump 1 whose pipe unions 4 and 5 are welded to corresponding pipelines. Each supporting device 6 has the form of supporting plate 7 resting on rollers 8, and a package of damper plate springs 9 assembled in sleeve 10 and pressed upon via disc 11 by adjusting screw 12 turned into threaded bushing 13 of supporting device 6. Each supporting device 6 has rod 14. Coaxial holes 15 in screw 12, disc 11 and bottom of sleeve 10 of springs 9 of each supporting device 6 receive rod 14 installed in a spaced relation . One end of said rod is attached to supporting plate 7 while the other one is disposed above end of screw 12. In case of thermal expansion of circuit pipelines, loads on supporting devices are redistributed and this results in breaking off or weaker reaction of said devices 6. Supporting device 6 extends and the value of its load changes is determined by changes in the length of the protruding end of rod 14. By turning screw 12, spring 9 is lifted thereby increasing the rigidity of plant fastening. This reduces vibrations of plant. EFFECT: higher reliability of pumping plant. 2 dwg
