Hydraulic Coupling Disadvantage for Industrial Fans And Blowers by Xianrun Blower

Hydraulic Coupling Disadvantage for Industrial Fans And Blowers by Xianrun Blower

(1) Hydraulic coupling always has slip ratio and power loss.The rated efficiency of torque-limiting hydraulic coupling is approximately equal to 0.96, the variable speed hydraulic coupler efficiency relative centrifugal fans is between 0.85 ~ 0.97;
(2) The output speed is always lower than the input speed, and the output rotational speed cannot be as accurate as gear transmission speed;

(3) The speed control type hydraulic coupler need additional cooling system, so increase the investment and operation cost;
(4) Large covering area, so it needs a certain space between motor and industrial fans and blowers;
(5) Narrow range of speed regulation;
(6) The ability of transmitted power is directly proportional to the square of the input speed. If the input speed is too low, the coupler specification will increase, and decrease cost performance.

The Hydraulic Coupling Transformation for Power Plant Fans And Blowers by Xianrun Blower

The original base of ID fan does not change, just need to transform motor position properly, and fill motor foundation on the motor end. In this case, the transformation construction is small, and just invest in the hydraulic coupling and filling foundation part.
