Calculation method of cooling tower motor power

  In order to correctly select the power of the cooling tower motor, the following calculations or comparisons must be made. China trlon air-conditioning will introduce users to the calculation method of the cooling tower motor and tower motor power.UDoCooling tower noise reduction treatment manufacturer

  (1) Regarding the continuous operation of stable load, if the power of the load (ie the power on the mechanical shaft of the cooling tower) Pl(kw) is known, the required cooling tower machine motor power P(kw) can be calculated as follows: P = During P1 / n1n2, n1 is the power of the production machinery, and n2 is the power of the cooling tower machine motor, that is, the transmission power.UDoCooling tower noise reduction treatment manufacturer

  The power calculated by the above formula is not necessarily the same as the product power. Therefore, the additional power of the selected cooling tower motor should be equal to or slightly greater than the calculated power.UDoCooling tower noise reduction treatment manufacturer

  (2) Compared with motors with the same power and extra value for continuous operation, the cooling tower machine motor with extra value for short-term operation has larger torque, smaller weight and lower price. Therefore, when conditions permit, cooling tower motors with short extra working hours should be used as much as possible.UDoCooling tower noise reduction treatment manufacturer

  (3) Regarding the additional intermittent operation of the cooling tower motor, the power should be selected according to the size of the load duration, and the motor should be selected specifically for the form of intermittent operation. The calculation formula of the load duration time string Fs% is FS% = tg /(tg + to)×100%, during which tg is the operation time t, is the suspension time min, and tg 0 is the operation cycle time min.UDoCooling tower noise reduction treatment manufacturer

  The above is an introduction to the calculation method of the cooling tower motor power. Next time, everyone here will introduce how to choose the power of cooling tower motor correctly.UDoCooling tower noise reduction treatment manufacturer
