1、 Application scope of frequency conversion cabinet:
1. Widely used in various types of tap water supply systems in urban and rural areas
2. Constant pressure control of water supply for high-rise buildings, domestic and fire-fighting water, and closed-loop water supply for industrial production conditions
3. Automatic control of boiler feedwater pump and thermal heating circulation pump
4. Irrigation of farmland and control of fountains
5. Air conditioning system and cooling circulating water control
6. Secondary pressurization control of flow systems in water plants, pump stations, and petrochemical industries
7. TSLB frequency conversion cabinet can be used for various motor control cabinets that require energy-saving renovation or zero speed starting production lines.
2、 Design considerations for frequency conversion cabinets:
1) Heat dissipation issue: The heating of the frequency converter is caused by internal losses. It is necessary to dissipate heat from the frequency converter. We usually use fans for heat dissipation
2) Electromagnetic interference problem: When there are high-frequency impact loads such as welding machines and electroplating power supplies in the system, the frequency converter itself will be protected due to interference
3) The usage environment of the frequency conversion cabinet: waterproof, anti condensation, dustproof, and corrosion-resistant gas resistant
3、 Function of frequency conversion cabinet:
1) Control the operation of the electric motor;
2) Provide variable frequency power supply to the motor to change its speed.
