When starting the aerator, the steering and sound of the aerator should be checked in advance. If abnormal motor noise, reverse steering and unstable operation occur, the cause of the motor should be checked to eliminate the fault. For example, when you start the aerator, you hear a buzzing sound, then cut off the power in time, check if the motor circuit is running, if there is a defect, it should be repaired in time, after insurance, and then start running.
When working in harsh environments, the oxidizer should be equipped with thermal relays, thermal resistance protectors, temperature relays, electronic protection devices, etc.
During the operation of the aerator, it is necessary to observe whether there are any windings or accessories on the impeller at any time. If the motor load is removed in time to ensure normality; if it is found that the aerator is gradually sinking and the floating hopper leaks and ruptures, it should be repaired or replaced in time; If abnormal sound is found in the aerator, the reasons for the failure of gears and bearings should be checked and replaced in time; the power supply of the displacement aerator is cut off, and it is strictly forbidden to move the aerator by ropes and traction cables.
①In the high temperature weather in summer, the aerator should be started at noon in order to exert the best aeration effect. Since the photosynthesis of plants is the strongest at noon, the dissolved oxygen on the surface of the water body is the highest. If the aerator is used to stir, the saturated dissolved oxygen on the surface will be poured into the bottom layer, so that the dissolved oxygen in the upper and lower layers of the water body is uniform, thereby greatly improving the Total dissolved oxygen in the pond.
② When using the impeller type aerator, do not start the aerator in the evening. At that time, the phytoplankton in the water body stopped photosynthesis and could not increase the oxygen in the water body. After the aerator is started, the dissolved oxygen in the upper layer is injected into the lower layer, the dissolved oxygen in the upper layer is not replenished, and the dissolved oxygen in the lower layer is rapidly consumed. As a result, dissolved oxygen in the fish pond as a whole naturally increases and depletes without compensation. The best time to use the peroxidizer is to start the peroxidizer 1 hour before or 1 hour after the feed. Because the impeller aerator stirs the water, the water is circulating. The first is to increase the oxygen effect; the second is to transmit the taste of the feed to the surrounding areas of the pond, which plays a role in attracting food; the third is to make the fish form a conditioned reflex to eat and play a habitual role.
③ Fish floating heads often appear in fertilizers and pools in summer. At this time, the aerator should not be activated during the day. If the aerator is activated, the oxygen from the upper water body will enter the lower water body, and the fish head will die sooner. Therefore, only when the aerator is turned on between 2:00 pm and 8:00 am the next morning can the fish sink into the water without a floating head. 4 The best starting time during the day is: 2 hours before dawn to restore the dissolved oxygen in the pool water to more than 4mg/l; 8 hours and 2 hours in the morning to promote water exchange and continuously increase the dissolved oxygen in the pool water; 3 hours and 2 hours in the afternoon, for the direct demand at night. Oxygen stores large amounts of oxygen.
