INSTALLATION FOR PUMPING OFF LIQUIDS Russian patent published in 2005 - IPC

FIELD: production of installations for pumping off liquid mediums.

SUBSTANCE: the installation is intended mainly for emergency pumping off different including hot liquids from flooded-down underground communications, cellarages, wells, etc. with the help of a pump-stimulator located on the surface and a hydraulic drive pump located underground in a flooded space bound among themselves through a tank-separator by means of hoses of the high and low pressure basically located one inside another. The hydraulic link of the pump-stimulator high-pressure hose is exercised through a loop section, in the upper part of which there is a normally open valve for connection with the aerosphere. The tank-separator is supplied with a tool for link of its upper part with the aerosphere. The low pressure hose is connected with a tank-separator in its upper part through is tangentially the located channel. The pump stimulator inlet is located in lower part of the tank-separator. The pump stimulator is located below the upper part of the loop section and below than the low pressure hose of the tangential channel. The invention ensures reliable operation of the installation even in the case of ingress of great volumes of air into the pumping-off hydraulic drive pump, a quick putting the installation into operation, operation of the pump-stimulator without cavitation even under the high temperatures of the pumping-off liquids, simplified control of the pumping-off installation in different conditions of operation.

EFFECT: the invention ensures reliable operation of the installation, its quick putting into operation, cavitation-free operation of the pump-stimulator at high temperatures, simplified control.
