蓄電池叉車技術的發展趨勢!

  驅動電機和電子控制從交流直接流向交流發展。采用交流電控可以提高生產率,加速快,可以提高車速和門的提升速度,并高速驅動輸出扭矩。在相同的工作條件下,能耗小,可延長電池組單班使用時間。此外,交流電機沒有電刷和換向器,不需要定期維護,降低了整個交流控制系統的運行成本。

  Driving motor and electronic control develop from AC to AC. AC control can improve productivity, speed up, speed up the car and door, and drive the output torque at high speed. Under the same working conditions, the energy consumption is small, and the single shift service time of battery pack can be prolonged. In addition, the AC motor has no brush and commutator, and does not need regular maintenance, which reduces the operation cost of the entire AC control system.
  向電子系統的過渡。傳統的蓄電池叉車轉向系統采用機械轉向或液壓動力轉向。機械轉向的缺點如下。液壓助力轉向的缺點是浪費能源。采用電子轉向不僅控制了轉向力,而且液壓動力轉向節能約25%。
  Transition to electronic systems. Traditional steering system of battery forklift truck adopts mechanical steering or hydraulic power steering. The disadvantages of mechanical steering are as follows. The disadvantage of hydraulic power steering is the waste of energy. The use of electronic steering not only controls the steering force, but also saves about 25% of the energy by hydraulic power steering.
  控制系統正朝著集成化方向發展。隨著操作者對舒適性的要求,一體化控制成為一種發展趨勢。所謂綜合控制就是用一個控制手柄完成蓄電池叉車的所有控制動作:叉車向前/向后、龍門向前/向后、龍門向上/向下、貨物叉向前/向后、貨物叉向左/向右。這樣可以降低操作人員的勞動強度,提高勞動效率。
  The control system is developing towards integration. With the operator's requirement for comfort, integrated control has become a trend of development. The so-called integrated control is to use a control handle to complete all the control actions of the battery forklift: forklift forward/backward, gantry forward/backward, gantry up/down, cargo fork forward/backward, cargo fork left/right. This can reduce the labor intensity of operators and improve labor efficiency.
  制動系統向電子方向發展。為了減少制動沖擊,提高適用性,要求傳動系統的制動力矩可調,從而促進了可調力矩電磁制動器的發展。可調彈簧制動器制動轉矩,轉矩控制器,電子控制裝置、制動系統的機電一體化實現制動力矩可調功能的同時,也可用于轉矩控制器剎車磨損監控,提高系統的可靠性,降低運行維護成本。此外,可調力矩制動器可配置CAN總線接口,實現對制動器的遠程診斷和控制,實現制動器控制的網絡化運行。

  The brake system is developing towards electronics. In order to reduce braking impact and improve applicability, adjustable braking moment of transmission system is required, which promotes the development of adjustable moment electromagnetic brake. Adjustable spring brake braking torque, torque controller, electronic control device and electromechanical integration of braking system can realize the function of adjustable braking torque. At the same time, it can also be used to monitor braking wear of torque controller, improve the reliability of the system and reduce the cost of operation and maintenance. In addition, the adjustable moment brake can be configured with CAN bus interface to realize remote diagnosis and control of the brake and realize the networked operation of the brake control.
  應用液壓泵電機控制器。液壓泵的電機控制器可以控制電機實現門框升降/前進/后退的無級調速,還可以設置電機轉速來控制貨叉的傾斜/側向運動速度。采用液壓泵電機控制器可節省25%的能量,延長蓄電池組單班使用時間,降低液壓系統的發熱。
  Apply the motor controller of hydraulic pump. The motor controller of the hydraulic pump can control the motor to realize stepless speed regulation of the door frame lifting/forward/backward, and can also set the motor speed to control the tilt/lateral movement speed of the fork. Using the motor controller of hydraulic pump can save 25% energy, prolong the single-shift use time of battery group and reduce the heating of hydraulic system.
  門框下降采用荷載勢能回收技術。負載勢能回收技術可實現無級調速,節能5%。勢能負載恢復的原則是:當門框下,液壓泵變成一個液壓馬達,和汽車變成一個發電機負載的勢能轉化為電能充電電池,從而達到節能的目的。
  Load potential energy recovery technology is used for door frame descent. Load potential energy recovery technology can realize stepless speed regulation and save 5% energy. The principle of potential energy load recovery is: when the door frame, the hydraulic pump becomes a hydraulic motor, and the car becomes a generator load, the potential energy is converted into electric energy charging battery, so as to achieve the purpose of energy saving.
