Frequency conversion speed control cabinet

Frequency conversion speed control cabinet




- Product Brief

AP1 series variable frequency speed control cabinet is designed and manufactured in accordance with the national standard GB / T3797 "Electrical Control Equipment", and meets the standard of IEC 298 "AC Metal Closed Switchgear and Control Equipment".

Frequency conversion speed control cabinet can realize one inverter to control one or more motors according to different actual conditions of users. Various parameters of frequency converter can be set according to the actual situation of users'site, so that the equipment can be adjusted to the best working state, so as to meet the needs of different users.

Frequency control constant pressure water supply system is a typical application of frequency control cabinet. It is the best choice to replace traditional water supply facilities such as water tower, high water tank and pressure tank. The system is composed of water pump, frequency conversion speed control cabinet, pressure sensor and so on. Its core equipment is frequency converter. Frequency control cabinet with well-known brand frequency converter as the core components, with frequency conversion, power frequency two operating functions, remote, local two control methods. At the same time, users can install multi-section constant pressure water supply control device (that is, set different constant pressure at different times in 24 hours), using the frequency converter of the control cabinet to achieve the goal of constant pressure water supply. The converter is controlled by a large-capacity computer, and the system is characterized by automatic adaptability, automatic constant voltage, automatic fault detection and recording and displaying. A closed-loop measurement and control system is formed by using the stepless speed regulation function of the frequency converter and the pressure sensor on the pipe network. The output frequency of the frequency converter is automatically adjusted by the PID closed-loop control function of the frequency converter, so that the pressure of the pipe network is constant by stepless adjusting the speed of the motor. Because of the use of stepless speed regulation function, so in the course of operation without impact and low noise, thus greatly reducing the cost of maintenance, greatly reducing the intensity of the operator's labor.

Frequency conversion speed control cabinet can also be widely used in fans, injection machines and other occasions that need to adjust motor speed.
