Roots fan in the maintenance process there are some details that you need to know, about this issue Roots fan editor to take you to understand. 1. High current If the mechanical part of the Roots fan rattling, temperature, vibration is normal, just some dull, high current, generally in and out of the wind is unfavorable, the inlet filter, the shell set of ash, out of the pipeline valves are not fully open and clogging of the main reason. 2. Transmission belt abnormalities Transmission belt if wear slag, may be the belt and the bottom of the groove contact, the two belt theory is not parallel or the corresponding groove is not in a plane, the wheel is rough, and so on. 3. Bearing heat Roots fan bearing heat in operation is mostly due to bearing damage or poor lubrication and belt tension...

For Roots fan in the process of high temperature use of what details are you need to understand and know? On this issue Roots fan editorial take you to understand.

Roots blower in the use of the process can not be separated from the maintenance, then Roots blower should be how to carry out routine maintenance? On this issue Roots blower small make up take you to understand. When the fan is equipped with an outdoor unit, a rain shelter should be installed. It is not necessary to install the fan in a place where people often pay to prevent injuries and burns. Depending on the direction of the air intake and exhaust ports and the need for maintenance, the bottom perimeter of the root...

Three-leaf Roots blower in the use of the process of shedding, so what is the cause of three-leaf Roots blower shedding? On this issue of three-leaf Roots blower editorial take you to understand. 1. What should I do if I fall into the foreign matter? If we have to dismantle the inlet and outlet muffler or perform maintenance on the inlet muffler, certain accessories or sundries will fall into the fan. At this time, we need to remove the muffler of the fan, and then remove the foreign matter from the inside of the fan. And clean the inside. 2. Maintaining the inlet muffler in the right way When we maintain the inlet muffler, it is recommended to disassemble the inlet muffler separately and then maintain it. After disassembling, if there is in the impeller...

Roots blower in the use of the process of vibration, so what are the reasons that lead to the vibration of the Roots blower? On this issue Roots blower small make up to take you to understand. 1. Design reasons: Roots blower design is generally based on the fan's use of the environment, temperature, air volume, wind pressure, media, etc. to design, and Roots blower selection of some companies are not fully based on these factors, resulting in the existence of the following factors: fan design is not appropriate, the dynamic characteristics of the poor, vibration occurs in operation; structural irrationality, stress concentration; design of the working speed is close to or fall into the critical speed zone Thermal expansion calculation is not allowed, resulting in poor thermal alignment....

Roots blower in the process of using what are the common failures? On this issue Roots blower editorial take you to understand. First, the root cause of the operation failure Roots blower is through the two impeller engagement and work. The active impeller is dragged by the coupling (or belt drive) device connected with the motor, and the driven impeller is dragged by the synchronous gear mesh on the master and slave shafts. Therefore, the gear mesh is good or bad, the blower's safety and smooth operation plays an extremely important role. -Once the gears are damaged, it will lead to the damage of other parts. The rotor assembly is supported by bearings in the wall plate. The position of the support point, the size of the bearing clearance, the mounting accuracy, the bearing seat fit precision...

Roots fan in the process of using how to adjust the gap between them? On this issue Roots fan editorial take you to understand. 1. Adjust the gap between the shell: through the shell and the wall plate positioning pin holes to ensure that, because when dismantling the fan, must not damage the positioning pin holes. Impeller chassis 0.20-0.395 2. Adjust the impeller-impeller clearance: rotate the impeller to the position shown in the clearance schematic, press the driven gear to the mark of the active gear, then press it on the shaft, install the gear ring, stop the washer and lock Tighten the nuts in turn and lock the lock. Tighten the nut slightly. Rotate the impeller one turn. If it fails to rotate, turn the impeller to make contact with its upper part. ...

Roots fan in the use of the process of pneumatic noise is too large, so what is the reason for this situation? How should it be solved? On this issue Roots fan editorial take you to understand. 1, the installation of muffler In general, the aerodynamic noise radiated from the fan air intake and exhaust port is 10~20dB(A) higher than the noise radiated from other parts, therefore, when controlling the fan noise, the first thing to do is to install appropriate muffler on the air intake and exhaust official channel. The muffler is used on the fan, at present, both at home and abroad tend to use the resistive muffler, and the muffler with larger volume and narrower muffling channel has been seldom used, of course, the muffler...

Roots fan in the process of using the bearings appeared high temperature, then the main island Roots fan bearing temperature is too high for what reason? On this issue Roots fan editorial take you to understand eh a little. 1. Simple and practical is to add a sunshade on the outside of the fan, which is one of the direct methods of cooling. 2. If the axial fan, wear-resistant fan and other fan temperature is too high, it is likely that the fan is driving into, out of the gas pipeline gate is not closed. Solution: close the inlet and outlet pipe gate on the line. 3. In addition, due to the box caused by severe vibration, shaft and rolling bearing installation skewed, before and after the two bearings are not concentric, fan rolling bearing damage or shaft ...

Roots fan parts used in the process of wear and tear is unavoidable, about the Roots fan parts wear the following Roots fan editorial take you to understand eh a little. 1. Initial wear stage initial wear stage for the material wear stage, at this time between the blower parts on the surface of the unevenness and oxidation layer, decarburization layer, due to the operation of the Roots fan parts, the role of mutual friction is quickly smoothed. Roots fan due to the impeller in the body running without friction, do not need lubrication, so that the discharged gas does not contain oil. It is the ideal pneumatic conveying gas source for chemical, food and other industries. At this time, the equipment can show high productivity, although this is a short period of time...
