Control cabinet for water supply installation

Control cabinet for water supply installation

Technical specifications

Functions

The frequency conversion control cabinet is provided with multifunctional controls (such as regulation of motor operating frequency, stabilization of starting devices, overload protection, short-circuit protection, default phase protection, pump leakage, water shortage, motor over-temperature and electric leakage protection of control cabinet) and complete status displays, as well as single and multi-pump control-based mode of operation, various pump switching modes and starting methods of master devices. In addition, it is equipped with analog inputs (for speed control or feedback signal), PID control, pump switching control (for constant pressure), communication, macro-efficiency (with different specifications set according to occasions), multi-speed control, etc.

It features inherently excellent quality, aesthetic appearance, durability, and easy installation and operation, thus serving as a secure and reliable companion to all water pumps.

 Product features

Energy efficiency: 1. Compared with the conventional one, the control motor for frequency converter is of the most practical significance to energy conservation, namely, saving 50% of power consumption, by automatically adjusting the motor to operate in the most cost-effective condition according to water injection and delivery demand.

2. Decrease in operation costs: The conventional motor's operation costs comprise initial purchasing cost, maintenance cost and energy cost, of which the energy cost accounts for approximately 77% of the total costs. The operation costs will be greatly abated by reducing the energy cost by 44.3%, and owing to a decrease in maintenance and repairs resulting from less impact on the device after starting of the frequency converter.

 3. Increase in pressure control accuracy: The frequency conversion control system is capable of accurately controlling the pressure and enabling the output pressure of the frequency conversion control device to match the water injection rate set by the system. The output of the device varies according to the motor speed. Since the accuracy of such speed increases, it can change the system pressure of the pipe network within a range of 0.2kg, thus effectively improving efficiency of operation and greatly conserving energy as well.

 4. Service life extension of motor: The frequency converter starts the motor at 0Hz and its acceleration time for such staring is adjustable, so impact of starting on electric and mechanical components of the motor is lessened and the system is more reliable, which extends the service life of motor in turn. Additionally, frequency conversion control device is able to reduce the current fluctuation during starting and the fluctuating current will influence the power utilization of the grid and other electric equipment, but the frequency converter is effectively capable of minimizing the peak of starting current.

5. Noise reduction by frequency conversion control: The motor runs in an effective, uniform speed and steady manner after a frequency control of motor speed is performed according to the operating condition requirements, which greatly reduces the noise released while the motor is working.
