Principle
The gas it taken in through the inlet 1.As it enters the side channel 2,the rotating impeller 3 imparts velocity to the gas in the direction of rotation.Centrifugal force in the impeller blades aceelerates the gas outward and the pressure increase.Every accelerates the gas outward and the pressure increase.Every rotation adds kinetic energy resulting in the further increase of the pressure along the side channel.The side channel narrow at the rotor,sweeping the gas off the impeller blades and discharging it through the outlet silencer4 where it exits the side channel blower.

If the rated current of the motor is exceeded during operation, the voltage and frequency of the power supply should be checked and compared with data on the unit rating plate. Some blowers can’t be operated over the whole range of the performance curve.
Overload of the motor may occur due to excessive system back-pressure. In applications where over-pressure conditions may occur, a relief valve must be installed. The ring blower must not be subjected to shock or vibration loads.
The ring blower has a non-contact operation and does not normally require maintenance. Wearing parts are subject to the recommended maintenance intervals and are a constituent part of the applicable warranty claims. The service life of bearing parts depends on the operating hours, load, and other Influences such as temperature and operating pressure.
A. Transportation
Check all parts from damage during transport.
B. Installation assembly
The blowers are to be installed weather protected and are not to be stored outdoors unprotected. When the blowers are installed outdoors they must be covered. Install ring blower horizontally or vertically. Do not subject blowers to vibrations or shocks.Blower with base should be secured tightly at the site of operation on solid, even ground. The Ring Compressors can be installed in any direction, but when mounted vertically, the motor side should be upward.


Note! Work described here must be executed by a qualified electrician only. Connect the motor in accordance with the wiring diagram to be found in the terminal box. The blower has a single or three-phase motor as described on the motor plate. The motor should be protected with an overload switch.
D. Control of rotation direction
Startup the blower for a short moment, Check the rotation direction. The rotation direction on the impeller must be in accordance with arrows on the motor. If incorrect rotation is experienced, then check the wiring circuit in the terminal box.
Problem | Reason | Solutions |
Does not rotary | (1) Power system broke, the motor does not rotate (2) Exogenous impurity into the air pump (3) Water seeps into air pump bearings or bearings are rusted or bearing oil-free and then bearings are stuck (4) Bearing is damaged or bearing is oblique and then impeller and pump body are stuck. | (1) Check the power supply and motor to remove the fault ; (2) Decomposition air pump to eliminate exogenous impurity; (3) Clean or replace bearings and add grease ; (4) Disassemble and repair and replace the bearing; |
The motor is hot or burned | (1) Three-phase power is unbalanced or lack phase (2) The power plug is loose or the power plug is poor contact (3) The output tube is blocked, so the output pressure is extra high (it is higher than 80% of the highest pressure) | (1) Check the power voltage and power wiring; (2) Check the power wiring and replace the plug socket; (3) Check whether the diameter of the output pipe is reasonable, check whether there is foreign body clogging or the valve is closed |
Insufficient pressure-flow output, high air pump temperature, and excessive motor current. | (1) Air inlet filter is blocked by dust or foreign matter. (2)The foreign matter is blocked in the inlet of the pipe or the valve is closed. (3)There is a leak place in the outlet of the pipe. (4) The pressure relief valve is set too small (5) Wrong direction of air pump rotation | (1) Clean the filter element. (2) Clean and check the inlet of the pipe and open the valve (3) Check for leak places and take measures to plug them (4) Adjust the pressure relief valve (5) Change the three-phase connection of the power supply to make the pump rotate in the correct direction |
Sound abnormal and noisy | (1) Bearing wear, the impeller of the air blower is stuck (2) The foreign matter is in the air pump (3) There are loose parts in the air pump (4) The air pump is not properly placed on the land, it shakes during operation. The hard connection between the pump and the pipe, the angle of the pipe and the pump is not adjusted very well. | (1) Replace bearing or impeller. (2) Decompose and repair to remove foreign matter. (3) Check for looseness and tighten. (4) The Level place or fixed it in a more reliable place. (5) Using a hose to connect the air blower and hard pipe. |
