Description

Изобретением вл етс вихревой иасос с рабочим колесом, установленным ,на конце консольного вала.The invention is a vortex pump with an impeller mounted at the end of the cantilever shaft.

В известных насосах нодобного типа консольна часть вала е имеет опоры, что гариводит к его прогибу.In known pumps of the similar type, the cantilever part of the shaft e has supports, which leads to its deflection.

Предлагаемый «асое лишен указанного недостатка, так как в отличие от известных в нем при менена втулка, один конец которой укреплен в корпусе, а «а другом установлен подшипник, введенный внутрь отбортовки , имеющейс на конце вала.The proposed model is devoid of this drawback, since, unlike those known therein, a sleeve is used, one end of which is fixed in the housing, and the other has a bearing inserted into the inside of the flange at the end of the shaft.

На чертеже изображен продо.чьный разрез иасоса.The drawing shows the food section of the pump.

В корпусе / насоса размеп1,ено рабочее колесо 2, зкреггленйое на отбортовке 3 консольного вала 4. Втулка 5 одним концом жестко укреплена в корпусе /. На другом КОНце 1втулкн 5 устаиовлен подшипник 6, введенный внутрь отбортовки 3 вала 4. Сальник 7 отдел ет нагнетательную нолость насоса от полости втулки 5.In the housing (pump), the impeller is dismounted, the impeller 2, mounted on the flanging 3 of the cantilever shaft 4, is inserted. The sleeve 5 is rigidly fixed to the housing with one end /. At the other end of sleeve 1, a bearing 6 is inserted, which is inserted into the flange 3 of the shaft 4. The oil seal 7 separates the pumping pressure of the pump from the cavity of the sleeve 5.

Гильза 8 жестко соединена с отбортовкой 3 вала 4. Корпус / насоса снабжен крышкой 9 и подшипнИКом 10, расположенном со стороны привода .The sleeve 8 is rigidly connected with flared 3 shaft 4. The housing / pump is equipped with a cover 9 and a bearing 10, located on the drive side.

Claims

1. A vortex pump with an impeller mounted on the arm of a cantilever shaft, HI tea and so that, in order to prevent the console shaft portion from bending, a sleeve rigidly fixed at one end in the casing and nesup1 is used, and the other end is a ball bearing inserted into the flange on the end of the shaft.

2. The form of the siaco.ca execution is in accordance with clause 1, clause 1, so that, in order to seal the discharge cavity of the pump, the sleeve is provided with an annular recess in which the oil seal and g11 are located. connected to the flange shaft.
