      電壓高低對木屑顆粒機的影響往往是大家比較容易忽略的問題,電壓過高或者過低容易燒壞木屑顆粒機的電機,容易造成木屑顆粒機的產量降低,造成電機的功率降低,因此電壓對木屑顆粒機的影響是比較大的,尤其是沒有專門的安裝變壓器而使用木屑顆粒機的時候。因此電壓必須控制在木屑顆粒機額定電壓的-5%或者+10%才能夠正常的使用。
      The influence of voltage on the sawdust granulator is often ignored. If the voltage is too high or too low, it will easily burn out the motor of the sawdust granulator, which will reduce the output of the sawdust granulator and reduce the power of the motor. Therefore, the impact of the voltage on the sawdust granulator is relatively large, especially when the sawdust granulator is used without a special transformer Wait. Therefore, the voltage must be controlled at - 5% or + 10% of the rated voltage of the sawdust granulator before it can be used normally.
      一、木屑顆粒機批發產量低電流的測試方法:
      1、 Low current test method for the wholesale output of sawdust granulator:
      1、用鉗形電流表測量的運行電流等于或接近該電動機的額定電流時,表示達到該電動機運行的額定負荷,即電動機滿負荷。
      1. When the operating current measured by clamp ammeter is equal to or close to the rated current of the motor, it means that the rated load of the motor is reached, that is, the motor is at full load.
      2、知道電動機驅動的設備需要系數和正切數值,換算計算電流。當測量的電流達到計算電流時認為達到了該設備運行扭矩滿負荷。
      2. Know the required coefficient and tangent value of the equipment driven by motor, and convert and calculate the current. When the measured current reaches the calculated current, the operating torque of the equipment is considered to be full load.

      二、當電源頻率一定時.電源電壓的高低將直接影響木屑顆粒機的啟動特性。
      2、 When the power frequency is constant, the power supply voltage will directly affect the start-up characteristics of the sawdust granulator.
      1.當電源電壓過低時.電機的定子繞組所產生的旋轉磁場減弱。由于電磁轉矩與電源電壓的平方成正比,所以,電動機啟動轉矩不夠,造成電動機啟動困難將引起負載電流分量加大的數值大于激磁電流分量減少的數值。因此,定子電流增加.功率損耗加大.時間過長甚至會燒毀電動機。
      1. When the power supply voltage is too low, the rotating magnetic field produced by the stator winding of the motor is weakened. Because the electromagnetic torque is directly proportional to the square of the power supply voltage, the starting torque of the motor is not enough, which causes the difficulty of starting the motor, which will cause the increase of the load current component to be greater than the value of the reduction of the excitation current component. Therefore, the stator current increases and the power loss increases. If the time is too long, the motor will even be burned.
      電壓過低時電機轉速降低,風扇的散熱量減小而發熱,如果出現堵轉現象電機很容易燒毀。電壓過低會燒毀木屑顆粒機電動機 ;
      When the voltage is too low, the speed of the motor will decrease, the heat dissipation of the fan will be reduced and the heat will be generated. If there is locked rotor phenomenon, the motor is easy to burn out. If the voltage is too low, it will burn the motor of sawdust granulator;
      1)電機的勵磁電流不是簡單的電壓除以電阻得到,電機繞組是個電感,在電機旋轉時還有互感,電機的勵磁電流主要取決于互感影響下的感抗。
      1) The excitation current of the motor is not obtained by simply dividing the voltage by the resistance. The winding of the motor is an inductance and there is mutual inductance when the motor rotates. The excitation current of the motor mainly depends on the inductance under the influence of mutual inductance.
      2)電壓影響電機建立磁勢的高低。
      2) The voltage affects the level of the established magnetic potential of the motor.
      3)電機的散熱是按照額定轉速設計的。
      3) The heat dissipation of the motor is designed according to the rated speed.
      4)電壓低轉速下降,散熱效率下降,
      4) When the voltage is low, the rotational speed decreases and the heat dissipation efficiency decreases,
      5)感抗下降,電流增加(如特殊情況:電機啟動電流相當于短路電流),溫度上升。6)積累熱量,燒毀電機。
      5) The inductive reactance decreases, the current increases (for example, the starting current of the motor is equivalent to the short-circuit current), and the temperature rises. 6) Accumulate heat and burn the motor.
      2.當電源電壓過高時,同樣會使定子電流增加導致定子繞組過熱而超過允許范圍。所以,國家標準規定,電動機只有在電源電壓波動范圍為士5%之內的情況下方可長期使以用。同時電壓過高會導致電機的定子磁通接近飽和狀態,出現電流急劇加大,電機效率下降而發熱嚴重。
      2. When the power supply voltage is too high, the stator current will increase and the stator winding will overheat and exceed the allowable range. Therefore, the national standard stipulates that the motor can be used for a long time only when the power supply voltage fluctuation range is within ± 5%. At the same time, if the voltage is too high, the stator flux of the motor will close to saturation state, the current will increase sharply, the efficiency of the motor will decrease and the heating will be serious.
