Features of Turbo Blower

Important points for operating
When the turbo type blower is in operation, its pressure has an inverse ratio to the current. If the current is too high, the contactor will trip. In order to avoid tripping or for saving power, when the pipe is very short, or the resistance is very less, please use wind regulating disc. The total section area of the air hole should be less than 70% of the section area of the blower mouth.
A. For feeding air - Wind regulating disc is included under normal situation.
B. For inhaling air - CX-3 and CX-5 can be installed a muffler if necessary.
Inspection
When you receive the blower, please check following items ?
1. Do the contents on the label conform to what you order ?for example, voltage, hertz and power (KW).
2. Are there any damages during the transportation.
INSTALLATION
(1) Installation Site
Ambient Temperature and humidity should meet the following conditions:
■ Single phase - 5 ~ 40°C
■ There phase - 10 ~ 40°C
■ Select site with good ventilation and less dust and humidity.
■ Please use umbrella when installation is made on an open space.
(2) Methods of Installation:
1. Secure the installation with screw on leveling and hard foundation or base. Standard basic weight is generally about 3 times of blower. If the base is uneven, the blower stand may be deformed during fixing of screw. It is therefore that special attention should be made to install additional vibration control unit to reduce its noise.
2. Blower is normally designed to make bearing on axial leveling position. When suction inlet is upward or downward during application, the weight of impeller and rotor shaft are added on one side bearing to enlarge over load and thus reducing life of bearing. Please contact our business department first when vertical site is used.
WIRING
1. The system rated voltage and frequency The record value same as those indicated on the rating plate.
2. Voltage variance should be kept within +5% of a rated voltage, +10% is sometime used, but it is better not to use as its voltage is too big and is liable to be broken down.
3. Due to blower has no over load heat protection fixture, it is unable to control heat. Therefore, please install overload protective magnetic switch of same horsepower and safe current is adjusted below same value of nameplate.
4. Select enough thickness of electric wire according to horse power of motor and electric working methods in accordance with European Union Safety information can be obtained from such as: EN60204-1 ; EN60034 ; EN292 ; EN294 ; IEE Wiring regulations Particular industries and countries have further safety requirements. Refer to their trade & safety bodies.
5. Check direction of rotation .Turn on the switch for a while (twinkling) after completion of line connecting t check its rotation direction and noiseless. The arrow on blower indicates rotation direction. If rotation direction is wrong such as turning into 3 phase, just replace any 2 lines of 3 electric wires.
6. Grounding . Please install earth lines to prevent from electric leakage accident.
OPERATION
1.Part of blower
  (1) Overload will be happened when it is completely opened.
  (2) Avoid turn switch on and off repeatedly within one minute so as leading overheat of motor.
2.Control on frequency changer
  When frequency changer is used, power supply ripple is distorted, motor noise is loud , and vibration is big too.When using frequency changer for ooperation if leading to rise of temperature or vibration, please stop operation.
Please use it under following terms and conditions.
  (1) Maximum frequency (RPM) Must be kept within frequency as indicated and within rated amperage.
  (2) Minimum frequency (RPM) Must be kept over 30 Hz, and within a rated amperage
  (3) A single-phase motor can not be used to operate a frequency changer.
