求翻译：物料粘度不大，那么用可调速的电机是可以的，但客户操作会很不方便，调速电机的调节开关是在电机上，电机装在搅拌桶顶部，2500L的搅拌桶很高了。如果粘度大，就只能用变频器调速，如果用变频器调速则需要独立的电控柜，变频器不能固定在搅拌桶上是什么意思？

Material viscosity is small, then you can adjust the speed of the motor it is, however, client is not very user-friendly operation, the speed of the motor control switch is on the motor, the motor mounted on top of the jar and the 2500 L Blender is high. If the viscosity, the converter can be used t

The material viscosity is not big, then uses the electrical machinery which may modulate velocity is may, but the customer operation can not be very convenient, modulates velocity the electrical machinery regulating cock is on the electrical machinery, the electrical machinery installed in the agita

Material viscosity is unlikely, then of adjustable speed motor can be used, but customer operations will be very inconvenient, the adjustment switch is on the motor speed regulating motor, motor mounted on the top of the Blender, 2500L Blender is very high. If the viscosity, the only variable-freque
