Shandong Chang Sheng Machinery | cement plant roots blower | Roots Blower Weifang detailed description: The Roots blower test, you should start at low speed, and check the direction of rotation is correct; it must be the starting speed to the fan still before starting to Anti-speed reverse rotation, causing the switch to trip and motor damage. Roots blower is a positive displacement blower, his mechanical cavity contains a lot of space, whenever he was at work when there exist a lot of gas chamber, the air volume delivered can be controlled, and the mechanical and air volume is the number of revolutions proportional to the blower impeller is between the front and rear face and the fan cover and fan impeller by keeping this small gap, which would allow the flow of air change, Roots blower is very widely used in the market, his low noise , vibration, gas flow is strong and stable performance, smooth operation, the effect is very obvious, and take advantage of them will soon be known to the public, and has been put to good use. Centrifugal fan works: Due to the low gas flow rate, pressure changes little, generally do not need to consider the specific volume of gas changes, namely the gas as an incompressible fluid handling. When the motor driven rotation of the fan impeller rotates, the gas between the impeller blades also followed rotary blower smelting and casting, and throw these gases, the gas flow rate is increased under the action of centrifugal force, so that the gas in the flow kinetic energy is converted to static pressure energy, and then as a special gas pressurized fluid delivery Roots blower, so that the speed of static pressure can also be converted to energy, exhaust gases through the exhaust port, and in the middle of the formation of a certain impeller suction blower, due to Entrance negative pressure, so that the outside air at atmospheric pressure immediately fill the role in the continuous rotation of the impeller discharge and fill the gas constant, so as to achieve a continuous blast. The same power, wind pressure is inversely proportional to the amount of general process. The same power, high pressure, air flow will be relatively low aquatic oxygen blower, and large amount of wind, air pressure will be lower, so as to take full advantage of the power efficiency of the motor. The first time you use the first blower fan blower air load commissioning ⑴ new installation or repair should be through an empty load after commissioning. ⑵ blower concept empty load operation are: intake and exhaust valves under conditions of full operational. ⑶ no abnormal smell or smoke phenomenon and impact or friction sound, vibration velocity radial bearing parts is not greater than 6.3mm / s. ⑷ empty load running 30 minutes or so, as in the case of normal blower models, can be put into operation with a load, such as the discovery is not operating properly, check the load test run after exclusion still short. This is the first use of the blower should Precautions
