| CHARACTERISTICS |
| 1.Arcuate-bevel gears are used instead of worm gears, thereby economizing on energy with high efficiency,and saving over 20% electric energy over traditional models. |
| 2. The arcuate-bevel gear is made of chromium-manganese-titanium with carbon-nitride surface treatment. Ensuring long usage life spans and high rigidty. |
| 3. Mechanical seal is available to prevent oil leakage. |
| 4. Inside protectors are avaible to avoid the motor being accidentally burnt out. |
| 5.High effciency oxygen transferring ability with 3.5kgs O2/h. |
| 6.Have good water current circulation as the making of large aera water wave |
| 7. Easy assetment,Operation and mainteinance |
All parts of "YIYUAN" paddlewheel aerators are under remarkable design, strict quality control and long-term testing before putting them into the market.Following are the characteristics of the paddlewheel aerators :
1. Impeller
The specific gravity between frame and blade of impeller is 1:1.3 which centrifugal force will added to make great power of operating water current ourspecial impeller to enhance more oxygenation and stronger water length.
2. Motor Cover
One-piece blow molded HDPE motor cover or steen steel for weather protection, allow better heat dissipation of motor and easy for delivery.
3. Floater
One-piece blow molded of reinforced HDPE floater that could resist against acid-alkalinity and sun exposure, crack-free and no water seeping problem. Easy for delivery and installation. It never break even if throwing it down to the ground from the 3th floor.
5. Heavy-duty reducer
3phase 1:13 or 1:14 or 1:16 / 50hz/60hz area.
1phase 1:14 or 1:16/50hz/60hz area .
** With rust-inhibiting primer.
2.2 liters of #50 gear oil. Low resistance reducer assure best quality and low power consumption
6. Bearing
Special synthetic rubber bush of block-bearing could withstand higher temperature and resistance against continuous friction.
7. Perfect design of machine to create water circulation and excellent oxygenation.
Except for Paddlewheel Aerators, What Other Aquaculture Machineries does "YIYUAN" have ?
Not only paddlewheel aerators of YIYUAN have been ranking good reputation but other machineries are popularly being used by farmers. Other main products are specified as follows:
1. Paddlewheel aerators for shrimp cultured : 1HP / 2HP/3HP/4HP
2. Long-arm ( multi-impeller ) paddlewheel aerator for large area shrimp cultured : 3HP/4HP
3. Rotation Paddlewheel Aerator for cultured Fish : ( 2HP )
4. Air-O2 aerator : 1HP / 2HP
5. Automatic Feeder
6. Submersible water pump for aquaculture
7. Impeller Aerator
8. Airjet Aerator
** How is the directly effective depth and effective water length of the "YIYUAN" paddlewheel aerators?
1. Directly effective depth :
1HP paddlewheel aerator is 0.8M from the water level
2HP paddlewheel aerator is 1.2M from the water level
2. Effective water length :
1HP/ 2 impellers : 40 Meters
2HP/ 4 impellers : 70 Meters
During the strong water circulation, oxygen can be dissolved into the water to 2-3 meters water depth. The paddlewheel could also concentrate the waste, splash out the gas, adjust the water temperature and help the decomposition of organic matters.
** How many units of paddlewheel aerators to be used in the shrimp ponds ?
1. According to the stocking density :
1HP should be used 8 units in one HA pond if the stocking is 30 pcs / square meter.
2. According to the harvesting tons :
If the harvest expected is 4 Tons per HA should be installed in the pond 4 units of 2hp paddle wheel aerators ; the other words is 1 Ton / 1 unit.
** How to maintain the paddlewheel aerator ?
MOTOR:
1. After each harvest, sand off and brush away the rust on the surface of motor and repaint it. This is to prevent corrosion and enhance heat dissipation.2. Make sure the voltage is stable and normal when the machine is in operation. This is to prolong the life of motor.
REDUCER:
1. Replace gear lubrication oil after the machine being used for the first 360 hours and once every other 3,600 hours later. This is to reduce the friction and prolong the life of reducer. Gear oil #50 is being used and standard capacity is 2.2 liters. ( 1 gallon = 3.8 liters )
2. Maintain surface of the reducer as that of motor.
HDPE FLOATERS:
Clean off the fouling organisms on the floaters after each harvest. This is to maintain the normal submergance depth and optimal oxygenation.
** We also offer 18months warranty and conditions are as follows:
We provide repair and/or adjustment service for one year from the date of delivery ( B/L date ) against defects in workmanship and materials subject to the following requirements :
1. Motor damage by high/low voltage and/or short of electric phases which is incurred by power is not covered.
2. Part damage caused by buyer's failure to replace the gear oil in the reducer as detailed in the clause entitled "Recommended Maintanance Procedures" is not covered.
3. Evidence of impact and/or mishandling, tampering, chemical corrosion, use contrary to the applicable operation and/or installation instructions, or damage resulting from repair performed by other service shop.
