Product Features
1. Nanjing Kangzhuo Environmental Technology Co., Ltd. uses inverters of well-known brands
The KZ100 series inverters independently produced by our company are used as the core components of Kangzhuo inverter control cabinet, and the effect is better.
2. Well-designed
From design to selection of components and complete sets of production, our company's variable frequency control cabinets are strictly in accordance with the national 3C quality certification, strict control, high quality and strict requirements for each design, procurement, production, inspection, factory The process has strict quality management and tracking. Before designing, our design engineers according to the requirements of the customer, the site environment (temperature, humidity, electromagnetic radiation level, explosion-proof level, etc.); the specific parameters of the motor such as origin, rated current, rated voltage, number of phases, motor load type, Working system; motor starting method; the number of frequency converter cabinets to drive the motor, control cabinet control methods, such as manual / automatic, local / remote; power quality requirements for power supply applications, lightning protection, surge, electromagnetic radiation, in-depth understanding of the drive The mechanical characteristics of the machine, and then comprehensively consider which brand of inverter of that series is used as the core device of the electric drag. After comprehensive consideration, design the electrical schematic diagram. In the design, do some suppression measures for possible interference, For example, installing reactors for incoming and outgoing lines, isolating transformers, using shielded cables for sensors, and grounding the inverters separately, partly install lightning protection, surge protection measures, and other protective measures according to the installation location of the control cabinet.
After the design of the electrical control principle is completed, we will carry out targeted electrical process design, including electrical wiring, layout of component installation positions, and sheet metal design of the electrical cabinet. Consider whether to install according to the temperature and humidity of the environment Cooling fan, corresponding dehumidifier. Also, whether there is explosive gas, and other comprehensive selection of cabinet material, protection level and so on.
3. Well-assembled
In the process equipment, strictly follow the design and the country's corresponding wiring installation specifications. Strive to achieve beautiful and generous wiring, clear layers, firm and reliable wiring, and good contact. The markings are complete, clear and firm. The panel is neat and the components are arranged evenly and beautifully.
4. Strict inspection
The inspection adopts strict standards and strictly follows the design and inspection process. Once problems are found, they are tracked down until the problem is found, and sufficient tests are performed during inspection to ensure zero errors.
5, affordable. Thoughtful and timely after-sales service and timely delivery.
Applicable occasions
Our company's variable frequency control cabinet is mainly for fans and pumps. It mainly uses PLC technology and PID algorithm to intelligently adjust the operating frequency of the inverter to meet the needs of actual production.
Main application areas:
1. Widely used in urban and rural water supply systems.
2. Closed-loop constant-pressure water supply for high-rise buildings, domestic and firefighting water, and industrial water.
3. Automatic control of boiler make-up water pump and thermal heating circulation pump.
4. Farmland irrigation and fountain control.
5, air-conditioning control and cold water circulation control.
6. Flow control and secondary pressure control in water plants, pumping stations, and petrochemical industries.
7. Various energy-saving transformations and various production lines with high requirements on speed regulation performance.
8. Various occasions requiring constant pressure gas supply.
Fourth, installation and commissioning
1. First confirm that there is no explosive, corrosive gas or dust in the installation place of the frequency conversion control cabinet;
2. Confirm that there is no severe vibration at the installation place of the frequency conversion control cabinet. Reserve a maintenance channel during installation;
3. Confirm that the ambient temperature is between -5 C and 40 C, the relative humidity does not exceed 90% at normal temperature, and there is no condensation; if the ambient temperature and humidity exceed this requirement, a specially designed inverter control cabinet is required.
4. The power supply fluctuates between -10%-+ 10.
5. The altitude does not exceed 1000 meters.
Preparation before commissioning: confirm whether the control cabinet installation is in place; confirm whether the wiring inside the cabinet is loose or disconnected; confirm again whether the wiring of the inverter is incorrect, whether the DC and AC wiring are incorrect; whether the main power wiring is correct; whether the motor wiring is correct Correct; whether the cable model matches the selected motor (load); whether the rated power of the inverter is greater than or equal to the rated power of the selected motor; if it is a heavy load, the rated power of the inverter is greater than the motor power by one or two Grade; whether the setting value of the thermal relay is correct. Are there any extra wires or foreign objects in the cabinet? Close the main power circuit breaker and test once, and quickly disconnect it to see if the wiring is correct and the phase sequence is correct.
Debugging: There are no problems in the above links. According to the control requirements of the on-site process, set the parameters strictly in accordance with the instruction manual of the inverter. After setting, confirm whether the motor rated power, rated voltage, rated current and other parameters are correct, the protection parameters are set correctly, and the control method meets the process control requirements. After confirming that there is no error, start the test run, and judge whether it needs to be modified based on the signal on site Set the parameter value. For closed-loop control, especially constant pressure control, first adjust the P parameter when setting the PID. Generally, it is slowly adjusted from small to large. If the P parameter is set large, the system's adjustment speed is fast and it is easy to cause system oscillation and integration. The parameter can not be set too short. If the integration time is too short, the integral regulator will be too strong and repeated overshoot will occur, making the system unstable until oscillation occurs. The integration time is generally adjusted from large to small, gradually adjusting the integration time, and observing the adjustment effect of the system until the stable speed of the system reaches the requirements.
V. Maintenance
