In winter, organic fertilizer equipment may be damaged due to ice, and it is very important to detect whether the equipment is damaged in time. Here are some detection methods and precautions:

1. Visual inspection to check the surface of the equipment: observe whether there is ice or frost on the surface of the equipment, especially pipes, valves and joints.

2. Check the inside of the device: If possible, open the check port of the device to check whether the inside is frozen or the material is frozen.

3. Auditory inspection, listen to the sound of equipment operation: When starting the equipment, pay attention to whether there is abnormal noise or friction sound, which may be due to ice caused by the equipment parts stuck or wear.

4. Tactile inspection, touch the surface of the equipment: touch the surface and pipe of the equipment with your hand, feel its temperature, and determine whether there are signs of ice.

5. Instrument detection, the use of temperature sensors: Install temperature sensors for real-time monitoring of the equipment, when the temperature is lower than the set value, timely measures are taken.

6. Detect pressure and flow: Check the pressure gauge and flow meter of the equipment to see if there are abnormal readings, which may be due to blockage caused by ice.

7. Test the function of the equipment: carry out the functional test of the equipment, such as starting, running and stopping, etc., to see whether the equipment can work normally.

8. Regular inspection and maintenance: In winter, the frequency of inspection and maintenance of equipment should be increased to discover and deal with icing problems in a timely manner.

Through the above method, it can effectively detect whether the organic fertilizer equipment is damaged due to icing, so as to take timely measures to deal with it, and ensure the safety and normal operation of the organic fertilizer production line.
