Advantages and disadvantages of submersible booster

Diving pusher is one of mixed stirring and low-speed pushing, and it is an important equipment of activated sludge process. Submerged pusher produces strong turbulent flow which can be used to create water flow in the water circulation and nitrification, nitrogen removal and phosphorus removal stages in the pool.

Diving pushers have the following features:

one. Compact structure, small size, light weight;

two. Simple operation and maintenance, convenient installation and long service life;

three. The blade has a self-cleaning function;

four. Motor windings are Class F insulation, protection class IP68;

Fives. The friction material of the mechanical seal is made of corrosion-resistant tungsten carbide. All fasteners are made of stainless steel.

In addition, the depth of a pool equipped with a diving booster can be deepened up to a depth of 7m, which can reduce the floor area of ​​the pool and reduce the investment cost of the civil works.

The disadvantage of the submerged ejector is that after the equipment is used for a period of time, the seal may be easily burned due to wear of the motor, and the fixed guide rod may cause fatigue damage or underwater foot due to the great alternating stress generated when the flow guide works. The bolts are loose and damaged.
