快乐十分选5中3有钱吗 Variable frequency inverter (AC motor speed drive, VFD) manufacturer & supplier in China

Home » Applications
Variable frequency drive for winding solution Variable frequency drive for winding solution The current vector control variable frequency drive: Through complicated and accurate vector control algorithm, torque current closed loop control can be achieved for directly setting the output torque of regular induction motor control, replacing the above functions of torque motor and even obtaining higher performance.
Variable Frequency Drive for Constant Pressure Water Supply Variable Frequency Drive for Constant Pressure Water Supply In water supply system, constant pressure water supply refers to the control mode which controls the outlet pressure within the setting value by detecting the pipe and network pressure when the water amount in the pipe and network changes.
Variable frequency drive introduced here with built-in PID to perform the automatic constant pressure water supply for saving energy.
Variable frequency AC drive for air compressor Variable frequency AC drive for air compressor The electric system is consist of variable frequency drive, pressure sensor and other peripheral devices. The start & stop time of the inverter drive can be adjusted randomly (0~10min), means that acceleration when start & deceleration when stop can be adjusted randomly, meanwhile, you can match with S curve ACC/DEC time to start smoothly, which can minimum the impact of air compressor caused by start & stop.
AC inverter drive for veneer peeling AC inverter drive for veneer peeling The upgraded AC inverter drive controlled veneer peeling without the clamper, the round wood is not lamped by the clamping jaw, and the clamping has no relationship with the quality of wood. The wood block with uniform thickness and same length can be processed by adjusting the rotary cutting speed and shearing speed, on the premise of precision satisfaction to increase the processing efficiency and utilization rate of wood.
Variable Speed Drive for Sucker Rod Pumps Variable Speed Drive for Sucker Rod Pumps - The system in the multi-step speed control mode: two steps of high speed and low speed, the travel switches are fixed at the up-running end point and the down-running end point, the step speeds are changed by trigger the switches.
- The energy feedback unit is fixed to feed the regenerated energy back to the power grid.
- The function of the variable speed drive output relay terminal is set as failure warning output.
AC drive for belt conveyor AC drive for belt conveyor Energy saving: In normal condition, the mining motors’ power rating are enlarged too much to ensure the safety operation, but they don’t work at full load in most of the time, and it will cause huge electric loss while in light load or without load. After using of the variable frequency drive in the system, the speed of the belt can be adjusted automatically as the change of the load.
Current vector AC drive for centrifugal dehydrator Current vector AC drive for centrifugal dehydrator AC Drive System Configurations
1. Open loop vector control AC drive
2. Current vector control feature
3. Choose braking resistor according the motor power
4. Braking unit is required if the power is more than 15kW
Variable frequency drive for CNC machine solution Variable frequency drive for CNC machine solution The range of main spindle variable frequency variable speed is very wide, the VFD drive can achieve stepless speed regulation in the range of 0~300Hz, The variable frequency drive matches with CNC machine not only simplify complex mechanical drive mechanisms, such as gearbox, etc, but also make the operation easy & maintenance convenience;
Frequency inverter in construction elevator Frequency inverter in construction elevator The whole system consists of PLC, frequency inverter, energy feedback system, electric motor, reduction box, AC input reactor, transformer, operation hand shank etc., to control the start, stop, up going, down going, brake and every kinds of protection of the elevator. The elevator will work at the condition of high-efficiency, safe and stable, meanwhile, the regenerated energy while the elevator going down will be fed back to the power grid to save energy.
Frequency inverter drive for glass tempering furnace blower control Frequency inverter drive for glass tempering furnace blower control 120% rated torque acceleration or deceleration, smooth start and acceleration/ deceleration, motor’s current does not exceed the rated current, eliminating the impact on the power grid and equipment; Optimize the operational efficiency, and control the rotational speed of cooling blower by the variable frequency drive. The energy saving rate is more than 30%.
AC Drive Inverter for Paper Machines AC Drive Inverter for Paper Machines Speed regulation accuracy of transmission system is required to be 0.1%. The frequency accuracy of drive inverter should be 0.01Hz. The analog signal is exposed to electromagnetic interference which impacts the transmission precision and stability of paper machine. In order to enhance the accuracy and stability of system and anti-interference ability, the system takes PLC as the main drive unit, acceleration or deceleration at each step is controlled by button.
