The position of structure and second connecting pole is provided with position corresponding with the fixed branch angle in fixed branch angle, the main pump body structure
Put and also be provided with a fixed branch angle, the centre position at the fixed branch angle is provided with triangle reinforcement.
Further, the quantity of the pump cover fixing hole is 12, and is evenly distributed on the surrounding of the pump casing cover mouthful.
Further, the length of second connecting pole is more than the length of first connecting pole.
Further, the water inlet inside diameter is more than the inside diameter of the delivery port.
Beneficial effects of the present invention：
The present invention applies the safety and stability in powerful centrifugal pump more preferable, and assembling is more convenient, can be true
The sealing of link position is protected, making high-power centrifugal pump, effect is more preferable when in use, and service life is longer.
