| titleOfInvention | Device for water delivery from well |
| abstract | FIELD: devices and mechanisms designed for production of underground water and operation of water intakes, in particular, for pumping out of deep-well water to main lines of municipal water supply systems. SUBSTANCE: device includes electric pump with pressure pipeline on which appliance of hydraulic seal is installed. The hydraulic seal appliance consists of body and inflatable chamber. Appliance body is made in the form of upper and lower flanges on which upper and lower rims of chamber are mounted. Chamber is provided with nipple. Installed in hollow of inflatable chamber, on body lower flange, are bellows whose hollows are connected via water ways to hollow of pressure pipeline. EFFECT: fully excluded contamination of inflatable chamber and increased service life without preventive maintenance of hydraulic seal appliance. 2 dwg |
