Scientific installation and use of aerators Turning on the aerators can not only increase the amount of dissolved oxygen in the water, but also expose harmful gases. The impeller aerator can also agitate the water body and promote the exchange of the upper and lower water bodies. The scientific installation and use of aerator manufacturers can ensure the safety of water production.

1. Installation method

Generally, it is advisable to install two aerators per acre of water surface. The method is:

⑴ The two aerators should be installed on equidistant diagonal lines.

⑵ The aerator can be fixed on two floating buckets or cement piles so as not to affect the normal operation of the aerator.

⑶ The position of the impeller in the water should be aligned with the "waterline". If there is no "waterline", generally the upper end surface should be parallel to the water surface. The impeller blade is immersed in the water to a depth of 4 cm. Too deep will increase the load of the motor and damage it.

⑷ When the aerator is working, the agitating pool water spray should be even, and the coverage area should be 6-8 square meters.

2. Safe operation

⑴ Cut off the power supply during installation. The cable should be fixed on the rack with a lock clip and should not be allowed to hang into the water.

⑵ After the aerator enters the pool, the torque is very large and needs to be fixed. When the impeller rotates, the waves generated are very large, so you must not take a floating object to the aerator for observation.

⑶ If the aerator makes a "buzzing" sound when it is working, check the circuit. If there is a lack of phase operation, immediately cut off the power supply, connect the circuit and restart it.

⑷ The shield is a device that protects the power supply from rain and should be installed correctly; the junction box is susceptible to water erosion, so pay attention to protection.

⑸ When the aerator starts, if there are abnormal noises, reverse rotation, unstable operation, etc., it should be shut down immediately, and the abnormality should be eliminated before the machine is turned on again.

⑹ The aerator should be equipped with thermal relays, temperature relays, thermistor protectors and electronic protection devices.

⑺ Remove the windings or attachments on the impeller in time. The floating body should be inspected once a year, so as not to reduce the buoyancy due to the abrasion of the floating body, which may cause the motor load to increase and burn out.

⑻ When the aerator is launched into the water, the whole should be kept level and moved into the water to prevent oil from leaking from the air vent of the reducer. The motor is strictly forbidden to come into contact with water.

3. Energy-saving measures

Turn on the machine according to the following 3 time periods, which can save about 60% of electricity.

⑴ Turn on before dawn, when the air pressure is low, fish and various animals and plants have consumed oxygen overnight, and the dissolved oxygen in the pool can be restored to more than 4 mg/L within 1-2 hours of turning on.

⑵ Boot from 8:30 to 10:30 in the morning. This period is the time when the sun is relatively good throughout the day. Starting for 1-2 hours, in addition to adding oxygen to the water, it can also promote the exchange of water in the pool, and use the photosynthesis of phytoplankton to increase the amount of dissolved oxygen in the pool water.

⑶ Boot from 3pm to 5pm. At this time, the temperature is higher and the water temperature rises, the dissolved oxygen in the pond water decreases with the increase of the water temperature, and the fish's metabolism is vigorous, and the oxygen consumption increases accordingly. At this time, it can be turned on for 1-2 hours. In addition to directly supplying oxygen to the water to meet the growth needs of fish, the most important thing is to store a large amount of oxygen to ensure night needs.
