Roots blowers, rotary blowers are the property of volume, with two leaf rotor relative motion within the cylinder to compress and transport gas rotary compressor. This blower is simple structure, easy to manufacture high pressure blower, for low pressure gas delivery and pressurized situations, also be used as a vacuum pump. Its features are as follows: 1, due to the impeller operation without friction in the body, does not require lubrication, making the exhaust gas is not oil. Chemical, food and other industries ideal pneumatic conveying gas source. 2, blowers belong volume blower operation. When in use, along with changes in pressure, flow rate changes very little. However, as the speed and flow changes. Thus, the choice of pressure service a wide range, the flow rate can be achieved by selecting the speed and achieve the desired selection. Clover Roots blower is a dual impeller synchronous compression machines, each with two clover-type rotor bearing blower, using a pair of synchronized gears, the relative position of the two rotors remain unchanged. Fans empty load test run: (1) a new installation or fan should be overhauled after the load test run; (2) an empty load operation is under the intake, the exhaust valve is fully open conditions put into operation; (3) no abnormal smell or smoke phenomenon and impact or friction sound, vibration radial bearing parts is not greater than 6.3mm / s; (4) run about 30min empty load energy efficient blower, as in the case of normal small saving blower can be put into operation with a load, such as the discovery is not operating properly, immediately shut down for inspection, after the exclusion still as empty load operation.
