Technical Parameters:** 1. **Direct Start Control Cabinet:** - Motor Power: 0.37–15 kW - Control Voltage: 380V - Number of Pumps: 1–4 units 2. **Star-Delta Start Control Cabinet:** - Motor Power: 15–90 kW - Control Voltage: 380V - Number of Pumps: 1–5 units 3. **Auto-Decompression Start Control Cabinet:** - Motor Power: 15–160 kW - Control Voltage: 380V - Number of Pumps: 1–5 units 4. **Automatic Frequency Conversion Speed Control Cabinet:** - Motor Power: 0.18–250 kW - Control Voltage: 380V - Number of Pumps: 1–7 units - Pressure Control Accuracy: ±0.02 MPa **Pump Switching Modes:** - **Main and Backup Pump Selection:** The main and backup pumps are manually selected before starting. If the main pump fails, the backup pump automatically takes over. - **Timed Automatic Switching / Manual Switching:** Ideal for regular rotation of main and backup pumps to balance workload. Switching time can be set at 4 or 8 hours. - **Alternate Automatic Switching / Manual Switching:** Main and backup pumps alternate automatically with each start. Manual mode is also available. - **Multi-Pump Operation Modes:** - **One-for-One Preparation:** Two pumps can operate in “main I, prepare II” or “main II, prepare I.” - **Two-with-One Preparation:** Three pumps can work in “main I & II, prepare III” or similar combinations. - **Three-with-One Preparation:** Four pumps can be controlled in multiple configurations. - **Two-Use Mode:** Two pumps can be controlled independently or combined with a float switch for level-based control. - **Three-Use Mode:** Three pumps can be controlled with similar flexibility. - **Four-Use Mode:** Four pumps can be managed in various setups. All modes include manual override options. **Power Supply Options:** - **Single Power Supply:** Direct power input. - **Dual Power Supply:** Two power lines can be used, with automatic switching to standby power if the main fails. **Control Types:** - **Unlabeled (Level Control):** Uses a high-performance float switch for liquid level control. - **P-Type (Pressure Control):** Uses an external pressure gauge or controller for pressure-based pump control. - **T-Type (Temperature Control):** Controls based on temperature settings. - **S-Type (Time Control):** Allows users to set schedules for pump operation. - **K-Type (Air Conditioning Pump Control):** Designed for HVAC systems, ensuring safe operation. - **X-Type (Firefighting Control):** Complies with fire codes, supporting panel, pressure switch, and remote activation. - **L-Type (Submersible Sewage Pump Control):** Offers additional protection for submersible pumps, including leakage and overheating safeguards. **Starting Methods:** - **Direct Start:** Suitable for motors up to 15 kW. - **Y-Δ Start:** For motors between 15–45 kW (excluding submersible pumps). - **Auto-Coupling Start:** For motors above 11 kW when frequent starts are not required. This pump control cabinet is a reliable, flexible, and customizable solution for a wide range of pumping applications, ensuring efficient and safe operation in any environment.
