The control equipment in the intelligent greenhouse control system is a key part of the entire control. Of course, if the maintenance of the control equipment is not performed well, the life of the equipment will be seriously shortened, and the misinterpretation of the control instructions by the control equipment will cause the control to fail. Therefore, in the usual equipment maintenance, Xinxin IOT experts remind everyone to do the following protective measures.
V. Maintenance and repair methods of wet curtain system
1. Maintenance of wet curtain system
(1). In order to achieve the effect of humidification when the wet curtain system is working, the side windows and roof windows of the greenhouse should be closed to prevent moisture from diffusing outside the greenhouse.
(2). The blower of the wet curtain should not be turned off immediately after the water flow is stopped, it is necessary to wait until all the water on the wet curtain has evaporated, so as to ensure the service life of the wet curtain.
(3) Do not immerse the lower part of the wet curtain. Long-term immersion in the water will cause mold or moss on the wet curtain.
(4) The water used in the wet curtain should be clean water with better water quality, which is also a protection for the wet curtain system. Check and clean the wet curtain system regularly to ensure the cleanliness of the water supply system and the wet curtain.
(5). To prevent the wet curtain from being damaged due to the entry of animals.
(6). If there are debris such as moss on the wet curtain, the surface debris should be cleaned with a slender soft bristle brush, and then washed with slow flowing water and dried.
(7). The power supply voltage of the wet curtain blower should be kept stable, not to exceed the upper and lower 10% of the rated voltage, and the phase order of the three items of electricity should be correct.
(8). After the wet curtain blower is not used for a long time, it should be checked whether the circuit is intact before restarting. After the test, the power is turned on for trial operation. If there is no abnormality, it can continue to run.
(9). The motor of the wet curtain blower also needs to periodically change the oil and add the lubricating oil. Regularly adjust the balance of the fan blades.
(10). Regularly remove dust and debris on the wet curtain blower, keep the fan blades dry, and avoid rust.
(11). When the blower is running, try to keep the voltage and current stable. Avoid the impact and vibration of fan blades.
2.Troubleshooting and maintenance of wet curtain system
(1). Wet curtain is uneven
Solution: Check the installation of the wet curtain to see if the water supply pipe is installed evenly. Check or control the flow of the water supply system, or check whether the water supply pipe is blocked.
(2). Leakage of wet curtain system
Solution: Check whether the water supply of the water supply system is too large, the water pipe is installed correctly; whether the water pipe or wet curtain is damaged, and whether the edge is damaged.
(3). Fan operation is unstable and violent vibration occurs
Solution: Check the firmness of the fan blades, strengthen the fan blades, correct the fan blade balance, check whether the drive shaft is loose, and fix the drive shaft.
(4). The motor current is too large or the temperature rises quickly
Solution: repair or replace the motor; adjust the input voltage of the motor.
Sixth, the intelligent electrical control system maintenance of the entire greenhouse
(1). The intelligent control cabinet must be well waterproofed to prevent water droplets from entering and causing the entire circuit to short circuit.
(2). If the equipment of the control cabinet is damaged, it should be repaired by professionals, paying attention to safety as much as possible.
(3). The operators of the equipment in the control cabinet need to be trained to avoid damage to the equipment and circuits caused by misoperation.
(4). The installation of cable routing needs to be protected to avoid cable damage.
(5) The power supply voltage should be distinguished to avoid electrical damage caused by the voltage.
Seven, other important matters needing attention
1. Clear the snow on the roof in time.
2. Close the doors and windows of the shed and close the shade curtains in strong wind, heavy rain and snowy days.
3. The impurities on the roof of the greenhouse should be removed in time, and the impurities on the equipment should be removed in time.
4. Turn off the power when the equipment is not in use.
