Russian refineries are used groups of ten thousand pumping units, basically centrifugal pumps, both Russian and foreign production. It’s power ranges from tens kilowatts to tens megawatts.
Technological settings of primary oil processing, catalytic cracking, catalytic reforming and others contains a different number of units, which ranges from groups of ten to hundred units depending on powers of settings. Specialists never raised doubts the necessity an anti-accident protection a powerful compressor and other unique machines, but not a pumps, which high concentration in modern technological settings however offen was reason of damages and other production troubles.
Really, if we take probability of pump trouble-free operation in day equal 0.99, then for the group of machines, containing 100 units, refusal probability close to 1, and the technological system herewith practically disabled. For reaching stability of a technological system to different perturbations, including failures of motor pumps, it is necessary to provide overseeing with the exterior on it exterior and interior factors describing its availability index of product, and control by its state by means of opportune acceptance of engineering and organizational measures.
