Greenhouses are getting bigger and bigger, but the more precious the crop, the more difficult it is to manage and the more risky it is. Therefore, to summarize the environment of each greenhouse and the growth status of crops, the following will take you to see the application of multi-story vegetable greenhouse heating device:
1.Heating fixtures, such as electric heating plates, heating fans, and oil-air heaters, are used to heat the cold winters.
When in use, one or more groups of heating can be started at the same time according to the number of installed units;Generally speaking, the electricity of the heating unit is very large. A method to reduce the potential safety hazards caused by the excessive size of the power installation in operation is proposed.
2.Appliance switches are equipped with a "start-stop" dual speed switch for on-demand control. Work starts as soon as the work light comes on.
3.Due to the high load of the electric heating plate, it is necessary to carefully check the heat generation of the wires and various parts when using. In case of accidents, the main power supply should be cut off immediately.
4.Before the rainy season arrives, the drains should be inspected and cleaned, and drainage facilities such as drainage pumps, work lines should be prepared. Drainage ditches and embankments can also be excavated if necessary so as not to damage the facility.
5.In winter, as the temperature drops, there will be a variety of problems with the vegetables in the greenhouse. Before that, we have to be prepared, from reducing the yield and quality of vegetables to drastically reducing the yield.
I hope the above sharing can help everyone!
