Abstract
Шестеренный дозирующий насос с повышенным сроком эксплуатации, состоящий из корпуса с входным и выходным отверстием, приводного вала, верхней пластины шестеренного механизма, статора шестеренного механизма, нижней пластины шестеренного механизма, ведущей шестерни, ведомой шестерни, оси ведомой шестерни, прижимной пластины, стяжного болта с гайкой, верхней и нижней направляющей втулки вала, отличающийся тем, что шестерни насоса изготовлены из самосмазывающегося композиционного материала с полиимидной матрицей с пластификатором - лецитином, а в приводном валу, где наблюдается контакт вала с верхней и нижней пластиной, вырезаны пазы, в которые установлены втулки из самосмазывающей композиции, при этом, зазор между внутренней поверхностью статора и диаметром шестерен составляет 8…10 мкм, зазор между приводным валом и внутренним диаметром ведущей шестерни составляет 5…7 мкм, зазор между осью и ведомой шестерней составляет 5…7 мкм. Long-life gear metering pump, consisting of a housing with an inlet and outlet, a drive shaft, an upper gear plate, a gear stator, a lower gear plate, a pinion gear, a driven gear, an driven gear axis, a pressure plate, a clamp bolt with nut, upper and lower guide sleeve of the shaft, characterized in that the gears of the pump are made of a self-lubricating composite material with a polyimide matrix with a plasticizer - lezi otherwise, and in the drive shaft, where the shaft is in contact with the upper and lower plate, grooves are cut into which the sleeves are mounted from a self-lubricating composition, while the gap between the inner surface of the stator and the diameter of the gears is 8 ... 10 μm, the gap between the drive shaft and the inner diameter of the pinion gear is 5 ... 7 microns, the gap between the axis and the driven gear is 5 ... 7 microns.
