The reason why roots blower can't rotate
1、 A brief introduction
When Roots blower This usually occurs when used in a relatively humid environment, or when the humidity in the medium conveyed by the fan is relatively high. Even in the printing and dyeing vacuum dehydration industry, there is a large amount of water entering the fan, and the internal appearance of the fan may rust during the fan shutdown. It is recommended that the user first drain the water in the fan to avoid the above situation.
1. Poor circuit - repair the circuit;
2. Motor failure repair motor;
3. The foreign matters in the cylinder of the inlet muffler fall into - remove the foreign matters in the cylinder;
4. If the rotor is stuck due to corrosion, clean the rust on the rotor;
5. If there are foreign matters on the gear meshing part, clean the foreign matters on the gear;
6. Roots blower Excessive pipe resistance at outlet - pipe blocked or inlet and outlet valves open.
2、 Detailed introduction
Today, I'll tell you how to use Roots blower You may encounter a situation where the master card of the host card does not move, usually on an old machine that has been running for more than a few years. In general, users of this kind of problem can contact the manufacturer and have professional technicians guide them to complete the inspection and guide the maintenance! Because each user has different reasons for not turning, the solutions are also different! The following Hongguang editor will analyze the detailed introduction of the causes of immobility and solve the problems according to the causes.
1: foreign body falling in
Roots blower There are a lot of dust and impurities in the air intake, which is caused by the particles entering the impeller. The impeller is stuck! It is more likely to occur in the application of conveying fly ash and granular materials. When roots blower transports the gas containing large star dust impurities for a long time, these dust impurities will stick to the impeller or between the impeller and the blower shell, which is easy to cause Roots blower Blocked. If there are a lot of impurities in the transported impurities, the inlet dust filter should be installed at the inlet flange of Roots blower. At the same time, it is necessary to clean the filter cotton at the air inlet in time! If there are large particles in the cavity of the conveying medium, it is easy to block the gap between the components, thus causing Roots blower Cannot rotate. At this point, we need to clean up Roots blower For the foreign matter in the cavity, check the clearance between the impeller and impeller, and check the cause of the foreign matter falling in, so as to prevent the failure again.
2: pipe blockage
Blockage of the main pipe can also cause the fan to stop rotating. When the pipe is under pressure, the motor torque limit is reached. In this case, the damage to the motor is relatively large, and easy to burn the motor! This situation mainly occurs in Roots blower Runtime. If the pipeline is blocked, its pressure will rise sharply in a short time, and the noise equipment will suddenly stop running. stay Roots blower In order to ensure the normal operation of the fan, the condition of the pipeline and gate valve should be checked regularly, and the change of the pressure gauge of the fan should be monitored frequently. Users only need to check regularly to prevent such failures.
3: machining accuracy of impeller
When Roots blower When the machining precision of impeller is not enough, the material is unqualified and the debugging is not accurate, it is easy to cause adhesion between operation gaps. Our roots blower has passed a series of strict tests before leaving the factory. We use professional CNC machine tools with high machining accuracy, and the dynamic balance of impeller has been strictly tested before delivery!
4: gear engagement
In daily use, Roots blower The normal meshing area of impeller is about 2 / 3. If it is larger than the meshing area, the meshing force between the gears will be too large, leading to the main engine unable to rotate, and finally roots blower can not rotate. The main problem is that the user is easy to occur in the installation process after disassembly. Therefore, if the user does not have certain technical conditions, it is recommended that the manufacturer be contacted by professional technicians to complete the operation!
5: internal rust
Long time used Roots blower Improper installation environment, maintenance and repair or the medium contained in the conveying medium is easy to cause rust inside and outside the fan. Because the gap between impellers is very small, it will lead to rust between impeller and wall panel or cabinet. At the same time, if it is placed for a long time, a large area of corrosion will fall off and the impeller will be stuck. At this time, we can use kerosene immersion, gasoline flushing and other measures to deal with the fan rust, and then readjust the clearance to solve the problem.
6: impeller damaged
Roots blower Impeller damage, impeller and impeller mesh with each other and unable to rotate, which leads to roots blower can not rotate. In this case, we should recheck the blower casing.
7: the bearing is damaged
Roots blower The internal friction of the impeller may cause damage to the inner bearing of the blower. In severe cases, the blower may not rotate. This is the indirect reason for the change of impeller clearance and the common cause of impeller non rotation.
8: internal deformation
This situation is mainly due to the purchase of unqualified Roots blower A few wind turbine manufacturers blindly reduce the cost, resulting in the strength of parts does not meet the standard. In addition, the long-term placement of fan equipment will also cause some deformation of parts.
9: the motor is damaged
If it is not operated for a long time Roots blower In case of motor failure, the fan will not rotate. At this time, we should check the fan motor, and then troubleshooting.
The above is a brief introduction and detailed introduction of the fan that can not rotate normally. You can eliminate the fan fault according to your own actual situation. In combination with the detailed introduction, we can deal with the fault more quickly and accurately. If there is any problem in the process, we can contact the customer service of our professional manufacturer, no matter which blower we are, we will be patient Ask you to answer, until the troubleshooting, welcome to call.
