Rotary blower the 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.
