Portion's sealing washbowl includes outer rubber washbowl and interior metal anti-wear cover bowl, and described interior metal anti-wear cover bowl is flush-mounted in described outer rubber pad
The inner peripheral surface of bowl, top the rim of a bowl of described interior metal anti-wear cover bowl with diameter greater than top the rim of a bowl diameter of described outer rubber washbowl,
Bottom the rim of a bowl diameter of described interior metal anti-wear cover bowl is less than bottom the rim of a bowl diameter of described outer rubber washbowl.
As a kind of preferred technical scheme, described armature spindle includes arranging the rotor being integrated and rotating shaft, described rotating shaft
One end pass through described fixed plate stretch out hole.
As a kind of preferred technical scheme, described fixed plate is evenly equipped with four fixing holes.
Employ technique scheme, the beneficial effects of the utility model are：Because integral type top sealing washbowl includes
Outer rubber washbowl and interior metal anti-wear cover bowl, interior metal anti-wear cover bowl is flush-mounted in the inner peripheral surface of outer rubber washbowl, integral structure
Effectively prevent and make because metal abrasionproof teabowl with a cover rotates outer rubber sealing washbowl squeeze bad phenomenon, thus effectively anti-leak-stopping
Oil, gas leakage, more durable, product quality greatly promotes；In addition simplify the packaging technology of product, manufacturing cost substantially reduces.
