Description
Известные уплотнени самовсасывающих центробежных насосов, состо щие из нескольких колец, установленных в канавках стуницы рабочего колеса и контактирующих со втулкой корпуса, недостаточно эффективны в работе.Known seals of self-priming centrifugal pumps, consisting of several rings installed in the grooves of the stubs of the impeller and in contact with the housing sleeve, are not sufficiently effective in operation.
Отличительной особенностью описываемого уплотнени , составленного из нескольких колец, вл етс выполнение их из нескольких частей, кажда из которых надета на шпильку, закрепленную в ступице рабочего колеса.A distinctive feature of the described seal, composed of several rings, is their execution from several parts, each of which is put on a pin fixed in the impeller hub.
Такое выполнение уплотнени повыщает эффективность его в работе .This embodiment of the seal increases its efficiency in operation.
На чертеже показан центробежный насос с вертикальным валом в разрезе.The drawing shows a centrifugal pump with a vertical shaft in the section.
В ступице / рабочего колеса 2 выполнено несколько кольцевых канавок 3, в которые вставлены уплотнительные кольца 4 из фторопласта или другого эластичного материала.In the hub / impeller 2 there are several annular grooves 3 into which the sealing rings 4 are made of fluoroplastic or other elastic material.
Верхние кольца посажены на щпильки 5 и жестко закреплены в ступице, а нижнее кольцо 6 свободно вложено в канавку и служит сто ночным уплотнением.The upper rings are seated on the studs 5 and rigidly fixed in the hub, and the lower ring 6 is loosely inserted into the groove and serves as a one-night seal.
Во врем работы насоса кольца отбрасываютс центробежной силой и прижимаютс к графитовой втулке 7 корпуса 8 насоса. Между втулкой и ступицей создаетс необходимый зазор дл свободного вращени рабочего колеса.During operation of the pump, the rings are thrown off by centrifugal force and pressed against the graphite bushing 7 of the pump housing 8. Between the hub and the hub creates the necessary clearance for the free rotation of the impeller.
Предмет изобретени Subject invention
Устройство дл уплотнени вала центробежного насоса, состо щее из нескольких колец, установленных в канавках ступицы рабочего колеса и контактирующих со тулкой корпуса, отличающеес тем, что.A device for sealing the shaft of a centrifugal pump, consisting of several rings installed in the grooves of the impeller hub and in contact with the body shell, characterized in that.
с целью упрощени изготовлени колец и использовани центробежных сил дл прижати колец к втулке, они составлены из нескольких частей, калада из которых надета на шпильку, закрепленную в ступице рабочего колеса.in order to simplify the manufacture of rings and the use of centrifugal forces to press the rings against the sleeve, they are made up of several parts, each of which is worn on a pin attached to the impeller hub.
