蓄电池叉车技术的发展趋势!

来源:/ 日期:2019-09-18 发布人:admin

  驱动电机和电子控制从交流直接流向交流发展。采用交流电控可以提高生产率,加速快,可以提高车速和门的提升速度,并高速驱动输出扭矩。在相同的工作条件下,能耗小,可延长电池组单班使用时间。此外,交流电机没有电刷和换向器,不需要定期维护,降低了整个交流控制系统的运行成本。

  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.
  向电子系统的过渡。传统的蓄电池叉车转向系统采用机械转向或液压动力转向。机械转向的缺点如下。液压助力转向的缺点是浪费能源。采用电子转向不仅控制了转向力,而且液压动力转向节能约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.
  控制系统正朝着集成化方向发展。随着操作者对舒适性的要求,一体化控制成为一种发展趋势。所谓综合控制就是用一个控制手柄完成蓄电池叉车的所有控制动作:叉车向前/向后•●、龙门向前/向后•●、龙门向上/向下•●、货物叉向前/向后•●、货物叉向左/向右。这样可以降低操作人员的劳动强度,提高劳动效率。
  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.
  制动系统向电子方向发展。为了减少制动冲击,提高适用性,要求传动系统的制动力矩可调,从而促进了可调力矩电磁制动器的发展?傻鞯芍贫髦贫,转矩控制器,电子控制装置•●、制动系统的机电一体化实现制动力矩可调功能的同时,也可用于转矩控制器刹车磨损监控,提高系统的可靠性,降低运行维护成本。此外,可调力矩制动器可配置CAN总线接口,实现对制动器的远程诊断和控制,实现制动器控制的网络化运行。

  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.
  应用液压泵电机控制器。液压泵的电机控制器可以控制电机实现门框升降/前进/后退的无级调速,还可以设置电机转速来控制货叉的倾斜/侧向运动速度。采用液压泵电机控制器可节省25%的能量,延长蓄电池组单班使用时间,降低液压系统的发热。
  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.
  门框下降采用荷载势能回收技术。负载势能回收技术可实现无级调速,节能5%。势能负载恢复的原则是:当门框下,液压泵变成一个液压马达,和汽车变成一个发电机负载的势能转化为电能充电电池,从而达到节能的目的。
  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.
