FIELD: installations for supplying fluid under pressure.
SUBSTANCE: method comprises determining the value of pressure in the vessel preliminary filled with explosion-proof compressible fluid and connected with the distributing device, comparing the value with that required for operation of the motor, and switching valving by the command signal to the air-operated motor of the drive. When the value of pressure in the vessel is higher or equal to the permissible value, the explosion-proof fluid is supplied from the vessel to the air-operated motor, whereas the pumped fluid is not supplied from the pipeline. When the value of pressure is lower than the permissible value, the pumped fluid is supplied from the pipeline to the air-operated motor, and the fluid is not allowed to enter the vessel.
EFFECT: improved environmental protection.
