METHOD OF OIL PRESSURE STABILIZATION IN THE SYSTEM OF GREASING GAS-PUMPING UNIT Russian patent published in 2017 - IPC F01M1/00 

FIELD: machine engineering.

SUBSTANCE: method of stabilizing the oil pressure in the pumping unit lubrication system is implemented by the device, which is constructed as a hydraulic cylinder, comprising a housing, top and bottom covers, piston seal and the guide belt and air pipe. 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; the emergency generator is connected to provide electricity pumping unit. The parameters define the duct so that the air pressure is varied in the range of values greater than and less than the warning alarm setpoints.

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.
