Proof axial fans Fu Xingyuan ventilation fan performance curve diagram Axial

Motors YB series flameproof three-phase asynchronous motors diode voltage of 380 / 660V, motor base and welded into one body, the motor delivered by the cooling air flow impeller directly. Motor terminal box placed outside the body, easy wiring. Junction box with six terminals and a ground terminal, select the user according to the power supply voltage wiring requirements; when the supply voltage is 380V, the use △ connection, when the supply voltage is 660V, the use of Y-connection, the fan motor factory according △ wiring. Overview BDZ series low noise fan proof axial fans, taking the start from a sound source, low speed, high pressure coefficient design method, developed into big Hong length, spatial distortions, wide-blade tilt to drive at low speeds premise, the purpose of the required amount of wind, air pressure, with high efficiency, small vibration, smooth running characteristics. Fan Overview BT35-11 series axial fan is a new fan of the eighties on the basis of BT30-11 improved design, it BT30-11 fan has obvious advantages: ① structure is more reasonable; ② performance compared large increase, the total pressure was 89.5 percent effectiveness;
