Selection, installation and maintenance of oxygen increasing machine

1. Selection of oxygen increasing machine according to the characteristics of various oxygen increasing machines and breeding objects

General penaeusvannameibonne pond using microporous tube type aerator or waterwheel type aerator, conventional fish farming can be used impeller aerator, seed breeding by jet aerator.

2. Determine the number of aerator according to the area of the pond

In general, 3~5 mu of water is equipped with an aerator, and the number of oxygen increasing machines should be calculated in the large area of the pond.

3, determine the placement position of the oxygen increasing machine

The aerator is installed in the central or windy position of the pond, usually about 5 meters from the pool bank. The aerator installation should avoid the grass in the crab breeding pond in the position. The resettlement leaf wheel type aerator should ensure that the flow of water produced by the oxygen increasing machine does not stir up the sludge at the bottom of the pool.

4. Safety operation of oxygen increasing machine

It should be assembled in accordance with the instructions of the use and fixed in the pond. If the working condition of aerator is poor, users should equip with thermal relay and phase protection device. When the aerator starts, we must closely observe the operation. If there is abnormal noise and unstable operation, we should shut down immediately and eliminate abnormal phenomena before starting.

Two. Maintenance of oxygen increasing machine

1, the daily maintenance of the oxygen increasing machine

In the daily use of oxygen increasing machine should be regularly checked and maintained to ensure normal and safe use. The motor is the heart of the aerator, when used to regularly check, turn any abnormal sound, bearing damage; the gear box has no leakage, it needs to be replaced; the impeller is not deformed or damaged; check the line without phase operation are affected by water erosion of the junction box need to be replaced.

2, the post season maintenance of the oxygen increasing machine

A season after using aerator should disassemble maintenance, parts of foot grease, placed in ventilated and dry place, need to install the use.
