Variable frequency control cabinet

1、 Scope of application of frequency conversion speed control cabinet

The variable frequency speed control cabinet is used for controlling power equipment in industries such as electricity, metallurgy, coal, building materials, and other fields.

2、 Characteristics of Variable Frequency Speed Control Cabinet

1. The variable frequency speed control cabinet adopts high-performance imported variable frequency speed controllers, equipped with advanced digital microcomputer control technology, with a high degree of automation. It can achieve constant voltage variables, multiple constant voltage variables, multiple control modes for variable voltage variables, multiple start stop modes, stable pressure, and accuracy of ≤± 1%;

2. The energy-saving effect is significant, and the energy-saving rate can generally reach 20% to 50%;

3. Microcomputer control achieves variable frequency soft start for multiple pumps, with no impact current and minimal mechanical impact wear, which can extend the service life of equipment, improve system stability, and reduce impact on the power grid.

4. Multiple pumps in the equipment can achieve cyclic starting operation, which can balance the workload of each pump and further extend the pump life;

5. The microcomputer controller has powerful functions and flexible system design and configuration. It can set up control systems for up to 6 main pumps and 2 auxiliary small pumps according to requirements;

6. Suitable for various voltage levels of high and low voltage.

3、 Main performance of variable frequency speed control cabinet

1. The variable frequency speed control cabinet has complete fault self checking and self processing functions.

2. It can self diagnose overvoltage, undervoltage, overcurrent, overload, phase loss, short circuit, overheating, and frequency converter faults.

3. Timely emit sound and light signals, and be able to store abnormal states for maintenance and analysis;

4. Fully digital intelligent microcomputer control, which can modify operating parameters according to specific situations;

5. The variable frequency speed control cabinet can add various functions according to the needs of users:

Set up multiple sets of water level control interfaces, which can simultaneously control several water level signals and have water cut-off protection function.

Set a timed start stop program for b

C Reserve remote control interface to achieve central monitoring and management of equipment (optional for users)

Equipped with advanced human-machine interface (user selectable)

Dimensions mm (width x height x depth)=600 x 900 x 250 (one to two)

=700 x 1800 x 400 (one trailer for multiple units)

Note: Cabinets above 15KW are determined by the power and number of pumps.

Installation condition requirements

1. Before installation, carefully check whether there are any hard objects inside the pump body to avoid damaging the impeller and pump body during operation.

2. During installation, pipeline management should not be added to the pump to prevent deformation and affect normal operation.

3. Tighten the anchor bolts to prevent vibration during start-up from affecting the performance of the pump.

4. Install regulating valves on the inlet and outlet pipelines of the pump, and install pressure gauges near the pump outlet to control the pump's operation within rated conditions and ensure its normal use.
