METHOD OF OIL PRESSURE STABILIZATION IN SYSTEM OF GREASING GAS-PUMPING UNIT Russian patent published in 2017 - IPC F04D29/06 

FIELD: mechanical engineering.

SUBSTANCE: oil pressure stabilizing device in gas-pumping unit greasing system, which is located between the upper and lower legs perpendicular to the collector cylinder of greasing gas-pumping unit comprising a housing, an upper and a lower cover, piston with sealing and guide tape. The method comprises the steps, when the piston is moved from the upper position, wherein when the oil pressure in the greasing system, the value of which exceeds rod pressure on the piston, mentioned piston is in contact with the upper cover of the hydraulic cylinder, filled with oil, to the lower position under the influence of the rod during emergency fall the oil pressure in the lubrication system, thus displacing the oil in the grease collector; connect the emergency generator to provide electricity pumping unit. Thus, the mass and diameter of the rod are set so that the rod pressure on the piston varies in the range of more than and less hazard warning setting time for the maximum operation.

EFFECT: provision of the smooth start-up and connection of the emergency power supply of any kind for a separate pumping unit and guild emergency source.
