Roots blower is a type of displacement fan. There are two three blade impellers that rotate relatively in the space sealed by the casing and wall panel. Since each impeller is involute or the envelope of the epicycloid, the three blades of each impeller are identical, and the two impeller are also identical, which greatly reduces the processing difficulty. Numerical control equipment is used during impeller processing to ensure that a certain minimum clearance can be maintained no matter where the two impellers rotate, under the condition that the center distance between the two impellers is constant, so as to ensure that the gas leakage is within the allowable range.
Smooth oil If the smooth oil of equipment is short, the fan will continue to operate without oil. Impellers will collide, gears will wear each other, and then increase the load of the motor. It will only increase the load of the motor to accelerate the loss.
The problem of Roots blower itself is the quality problem of the factory. When installing the fan, many parts are poorly combined, which will constitute a rating conflict. Rules for maintenance and parts replacement of Roots blower consumer manufacturers, based on the preparatory work of blower fault analysis, confirm the repair location and scope, and prepare parts that may need to be replaced. Prepare suitable inspection items and measuring tools according to the structure of parts. According to the quality of the fan, the overhaul plan is formulated.
Implement safety measures. When removing precautions, the size of important parts and the direction of equipment shall be marked so that the check mark can be reset during assembly to avoid the occurrence of hidden drops. For example, measure the thickness of various shims and stop recording, measure the local clearance of the rotor and stop recording, and summarize the corresponding symbols on the main gear, driven gear and tooth slot.
Before installing Roots blower, clean and check the parts to be used. The appearance of disassembled parts shall be maintained and placed according to certain rules. Parts in the same part, such as bearing seat, bearing gland and conditioning washer of the same part, shall be placed together. The lost parts shall be included in the special equipment. Matched applications should be stored together.
During the operation of Roots blower, the current is too high and the motor is overloaded. There are many reasons for the high current of Roots blower. The common causes of pipe blockage are mainly pipe blockage, unstable fan outlet, unstable wind, pressure rise, motor caused overpressure overload, and then led to the rise of Roots blower ammeter.
Cause of lubricating oil If the Roots blower is short of lubricant, the blower will continue to operate without oil. Impeller failure conflicts and gear wear will be added, which will add motor load, which will only add motor wear and accelerate loss. Misoperation During operation, current overload may also be a problem.
If the check valve is reversely installed and the gate valve is not fully opened, this operation may lead to instantaneous burning of the motor, and should be carried out according to regulations during operation. Don't make unnecessary trouble at will. The fan factory has its own quality problems. When installing the fan, the clearance of many parts is poor, which will lead to the conflict of rating. In addition, some components may be damaged. If the motor is added with negative load, the fuse will blow.
If the current is too high, the roots blower motor is in overload operation condition, regardless of the fan's own reason or operation fault. In daily operation, we follow the correct operation in order to effectively prevent the problems of Roots blower. The application method and application process shall be frequently suspended and checked, and protection and defect elimination shall be carried out. This is an indispensable and useful approach.
I believe that after reading the above contents, you should also have a better understanding of the parts to be cleaned during the installation of Roots blower. I hope it will be helpful to you.
