Freshwater fish farming machinery - aerator (2)

Third, the aerator safety operation method In order to normal operation of the aerator, we should pay attention to the safe operation method. 1. Cut off the power supply during installation. The cable cannot be pulled as a rope in the pool. Use the lock clip to be fixed on the rack and do not drop into the water. The remaining parts are led to the shore power supply according to the electrician's relevant regulations. 2. After the aerator is switched on, the torsion is large and it must be fixed. When rotating, the waves produced are large and must not be observed in front of the aerator with floats. 3. When the aerator is working, if a “click” sound is issued, the line should be checked to see if there is any missing phase operation. If there is any, the power should be cut off immediately, and then the fuse should be connected and then restarted. 4. The shield is a device that protects the power supply from rain and should be properly installed; the junction box is vulnerable to water erosion and should be protected. 5. When the aerator is started, it is necessary to observe the steering and running conditions. If there is abnormal noise, reverse direction of rotation, and unsteady operation, stop the machine immediately and remove the abnormal phenomenon before turning on the machine. 6. The working conditions of aerators are poor. Users should provide their own thermal relays, temperature relays, thermistor protectors and electronic protection devices. 7. Pay attention to whether there are any windings or attachments on the impeller at ordinary times, and if necessary, remove them in time. The floating body should be inspected once a year to avoid lowering the buoyancy due to wear of the floating body, resulting in increased load and burning of the motor. 8. When the aerator is launched into the water, the whole should be kept horizontally moved into the water to prevent the reducer vent hole from spilling oil. At the same time, it is strictly forbidden for the motor to come into contact with water, so as to avoid burning out the motor due to flooding. 9. The aerator must be in charge of the person responsible. Responsible personnel should enhance safety awareness and record the operation and maintenance of the aerator. Fourth, aerator energy-saving measures Select the best boot time, can be efficient, high quality, low consumption, increase production, and promote the development of fisheries. According to experience, the following three hours boot, can be reduced from 6 hours to 10 hours to 3 hours to 5 hours, saving about 60% of electricity, but also to ensure the normal consumption of oxygen fish. 1, before dawn, when the pressure is low, fish and various animals and plants have consumed oxygen overnight, boot 1 hour to 2 hours to make the pool of water dissolved oxygen returned to 4 mg or more. 2. 8:30 to 10:30 in the morning. At this time, it is the best time of daylight illumination. After being turned on for 1 hour to 2 hours, it can not only add oxygen to the water, but also promote pool water exchange and use photosynthesis of phytoplankton to increase the amount of dissolved oxygen in the pool. 3, from 15:00 to 17:00 in the afternoon. At this time, the temperature is higher and the water temperature rises. The amount of dissolved oxygen in the pool decreases as the water temperature increases. The metabolism of fish in the body is high and the oxygen consumption increases. At this point, the system is turned on for 1 hour to 2 hours, and in addition to supplying oxygen directly to meet the needs of the water, the most important thing is to store large quantities of oxygen to ensure night-time needs. To master the correct use of methods, in addition to taking the above measures to choose the best boot time, but also because of the season, due to the weather, flexible use of the weather. For example, during the fish production season, when it is turned on for 0.5 hours to 1 hour at noon on sunny days, you can collect water and improve the water quality. If it is rainy or cloudy, it will not be opened during the day, which can prevent and solve the problem of floating heads.
