I. Safe Operation of Aerator
1. When installing the aerator, be sure to cut off the power supply. The cable should not be affected by the tension in the pool. Never use the cable as a rope. The cable should be fixed on the bracket with a locking clip. Do not drop it into the water. Press the rest The regulations lead to the shore power supply.
2. After the aerator is put into the pool, the torque is large and it must be fixed. When the aerator is rotating, the waves generated are very large. Do not take a floating body and observe it in front of the aerator.
3. The position of the impeller in the water should be aligned with the "waterline". If there is no “waterlineâ€, the upper end surface should be parallel to the water surface in order to prevent overloading and damage to the motor. The impeller blades are immersed in water with a depth of 4 cm. Too deep will increase the motor load and damage the motor.
4. When the aerator is working, it will check the line to see if there is any missing phase operation. If there is a need to cut off the power supply, connect the fuse and restart it.
5. The protective cover is a device that protects the motor from being wetted by water and must be properly installed.
6. When the aerator is started, it is necessary to closely observe the steering and operation conditions. If there is abnormal noise, reverse steering, unstable operation, etc., the machine shall be shut down immediately, and the abnormal phenomenon shall be eliminated before starting the machine.
7. The working conditions of aerators are poor. Users should provide their own thermal relays, temperature relays, thermistor protectors and electronic protection devices.
8, usually pay attention to whether there is a winding on the impeller or attachments, if any should be promptly removed. Every year, check the floating body so as not to reduce the buoyancy caused by the wear of the floating body, resulting in increased load and burning of the motor.
9. When the aerator is put into the water, the whole should be kept horizontal or moved into the water with little angle to prevent the vent hole of the reducer from spilling oil. At the same time, it is forbidden to contact the motor with water so as to avoid burning the motor due to flooding.
10. The oxygen aerator should be specially responsible for it. The responsible person should enhance safety awareness and make a record of the operation and maintenance of the aerator.
2. Maintenance of aerators After the aerator has been used for a period of time, its motors, gearboxes, impellers, buoys, and lines are vulnerable to damage and must be inspected and repaired. So, how to maintain the aerator?
1, the motor. The motor is the heart of the aerator. After a certain period of use, it is difficult to avoid dampness or bruising. When checking, rotate the rotor by hand and hear no friction or collision noise in the machine. If the fan blade collides with the casing, or if the stator and the rotor are rubbed, it must be repaired to adjust the gap. Check if the bearing is damaged. If it is not damaged, it should be removed and cleaned. If it is damaged, it should be replaced with a new one. Check if the carbon brush is worn, and polish the rust on the surface of the commutator to remove the dirt from the groove. It is necessary for the stator and rotor. Low-temperature baking removes moisture.
2, gear box. The reduction gear box is a heavy cast iron body and should be inspected. If the oil in the box has deteriorated, replace the oil that has been deteriorating, and wash the sand in the box to inject new oil. Check if the gasket is damaged. If the gasket leaks due to damage to the gasket, replace the new gasket.
3, impeller and buoy. Check whether the impeller is deformed or damaged, correct the deformed impeller, replace the damaged impeller, and check whether the weld of the pontoon is rusted or leaking. If the rust leaks, weld it.
4, line. Check whether the circuit is running in the missing phase. Check the junction box. If it is exposed to water, it should be replaced and waterproof protection of the junction box should be made. (Sichuan Wang Shoucheng)
