  The main components of the blast blower:

  Rotary blower structure compact, mainly consists of the following six parts:

  Motor, transition device, air blower, air chamber, the base of ontology () and fuel tank, drip nozzle.

  Rotary blower works:

  Blower run by cylinder offset in the rotor eccentricity, and between the blades of the rotor slot of volume change in air, compressed, spit out. Using the pressure difference between the blower in operation automatic lubrication to drip nozzle, drop into the cylinder to reduce friction and noise, and can keep the gas inside the cylinder does not return.

  The application of rotary blower use:

  Low water blast aeration low sewage of hospital, laboratory stirred aeration's vacuum paper printing industry low plating bath agitation aeration, industrial wastewater of low plastic welding, blowing air supply low burner spray, glass industry, and other.

  Why need to sewage treatment rotary blower:

  Activated sludge process is aerobic biological treatment method, in the process, in order to maintain life activities of microorganism, must make the pledge that we shall have a certain amount of dissolved oxygen in water. Rotary blower aeration effect.

  Rotary blowers, and other similar fan features and advantages:

  Low small volume, big air volume, low noise and save energy (rotary blower adopts the principle of operation of compressed air, although small, but large air volume, energy saving, mute function is unmatched by other forms of the fan.

  Stable running, convenient installation, small model as long as the place is in order when working with vibration is very small, do not need to add vibration control device, easy installation).

  Low resistance to the load change, the airflow stability (for example: sewage aeration tank pressure changes, load changes, but little air volume changes over pressure).

  With air chamber, smooth perforated (all models with air chamber, can prevent the air pulse, smooth perforated).

  Fine texture, structure, performance excellence (blower are all made of high quality materials, structure compact, strong and durable, performance is remarkable, the long-term use of less faults).

  Low maintenance is simple, less failure, long life, low speed, small abrasion, long service life).

  Rotary blower matters needing attention in the process of installation and commissioning:

  (a), the installation of rotary fan

  1, when transporting rotary blower please pay special attention to safety, to avoid rotary blower by collision and impact, and can't stand rotary blower handling, to prevent the oil from the tank to pour out.

  2, the wind room air vents shall be maintained and install exhaust fan, air vents to be located in the upper and lower two facilitating air convection, in order to prevent the engine temperature affect normal operation of rotary fan.

  3, the inner wall of the room around the best equipped with sound deadening materials to reduce noise.

  4, rotary fan should be installed.

  5, distribution pipe diameter should not less than rotary fan exhaust diameter, and pay attention to the pipe cleaning, send airway should be installed above the surface, in order to prevent the tube inlet starting when the pressure is too large.

  6, takeover attention don't pour the check valve twist (bumps on the check valve should be up).

  7, please correct answer the distribution lines and pay attention to the motor steering markers consistent with rotary fan rotation direction.

  8, using two rotary blower alternate runtime, avoid frequent exchange in a short time starting fan, hope a rotary blower of not less than 12 hours continuous running time.

  (2), rotary blower test run

  1, check the oil in the tank is up to standard (oil amount should be higher than the oil hole position).

  2, starting rotation before please take air inlet filter, blower to the host within 30 ml into the oil, the oil evenly distributed within the rotary blower (laps) by hand.

  3, check the firmness of V belt are appropriate, such as too loose, please adjust.

  4, check whether the valve is set at a specified pressure position, such as working pressure is 0.3 KGF/c ㎡; The relief valve opening pressure of 0.3 KGF/c ㎡. During commissioning, exhaust valve to the opening pressure of pressure can be adjusted manually, adjust the relief valve to just open (the pressure is 1.1 times of working pressure).

  5, starting fan power supply is connected, please pay attention to the following:

  A, rotary blower whether to agree with to mark directions, such as inconsistent to immediately stop the adjusting motor wiring.

  B, observe the pressure gauge with and without pressure indicator (sewage tank must be filled with water to run after rotary blower, or rotary blower outlet pressure, rotary blower no lubrication).

  C, observe the nozzle presence of oil drops out (10 to 12 drops/min), and observe whether there is oil inside the transparent return pipe flow.

  6, check the motor and rotary parts of the blower is normal operation, the temperature is normal, whether there is abnormal sound.

  Rotary blower factory should include the following:

  Each set including blower, motor, air filter, air chamber, drip nozzle, valve, check valve, outlet pressure gauge, the base and tank, shock absorber, gear, anchor bolt and bolt connection of the components and a lubricating oil.
