Pond aerator is a type of positive displacement fan in which two impellers rotate relative to each other in a sealed space between the enclosure and the wall panel. Because each impeller adopts the involute or cycloid envelope for the impeller processing line. The three blades of each impeller are completely the same, and the two impellers are also completely the same, which can greatly reduce the processing difficulties. Impeller in the processing of CNC equipment, to ensure that the two impellers will not change in the distance. Below, no matter what position the two impellers rotate to, they can maintain a certain small interval and do not touch each other when running.

The clearance between impeller and impeller, impeller and shell, impeller and wallboard is very small, so the air inlet forms a vacuum state, and the air enters the air inlet under the action of atmospheric pressure. Then, the two blades of each impeller, the wall panel and the shell form a sealed cavity, and the air in the inlet is continuously transported from the inlet to the outlet by the two blades while the impeller rotates.

Simply put, the pond aerator relies on a pair of impellers to force the gas from one end to the other for the purpose of the tuyere. What should be reviewed and maintained in the routine maintenance process?

1. Cooling: When the fan is running at high temperature and expired load, it is easy for the whole machine to overheat, the failure rate to increase and the airflow to decline. To this end, their own planning and production of simple water equipment. Take one-sided heat from above through the surface of the fan shell to achieve cooling intent, so that the fan can safely pass the high temperature season. The facility is simple and is open only during the hot season each year.

2. Air cleaning and regular inspection: in terms of air cleaning, use sponge as a filter screen, timely finishing, and cooperate with the cleaning of the blower, to meet the cleaning requirements of the fan and production requirements. The rule is to make hourly inspections, look, listen, feel, and check the outlet temperature, pressure and ammeter for overruns.

3. Add lubricating oil to the gear parts: butter on one side of the fuselage with a single tank, lubricating oil on one side, or lubricating oil on both sides if using a machine with two tanks. It's easy to maintain.
