Roots FansIn the process of starting the discharge of the situation, so what is the reason for this situation? On this issue Roots fan editorial take you to understand.
1, motor! Motor voltage is the same, the speed is the same, the demand force is bigger, do more work. Motor power increases, the current increases the current is too large, the protection system stops. No protection system motor burned out!
2. Fans! Fan by the heat generated by the compressed gas, heat can not be discharged in a timely manner! Fan heat, soften, brittle fan casing! Fan at the same time by two external forces 1, the motor on the fan spindle, bearings of the strong torsion. 2, the inner chamber pressure on the fan casing of the outward thrust. Combined with the heat and force, fan cracking, and even explosion are there, the casing cracked to repair those businesses, abound.
3, system piping, valves. The reasoning is the same as above, the valve blown up, flange burned, there are many.
