Direct Coupling Positive Roots Blower

The Yinchi direct connected Roots blower consists of five core components, none of which are indispensable. Firstly, the sturdy shell not only supports other components, but also serves a fixing role, ensuring the stability of the overall structure. Secondly, as a bridge connecting the casing and impeller, the wall panel not only supports the rotation of the impeller, but also achieves end face sealing, ensuring airtightness. The impeller, as the core rotating component of Roots blower, is divided into two types: two blades and three blades. However, considering the many advantages of three blade Roots fans, such as low outlet pulsation, low noise, and smooth operation, three blade Roots fans have gradually become the mainstream in the market. In addition, the role of the oil tank cannot be ignored. It stores lubricating oil for the gears and bearings, providing assurance for the long-term operation of the unit. Finally, the function of the muffler is to reduce the noise generated by the pulsation of the inlet and outlet airflow of the Roots blower, ensuring quiet and comfortable operation.

Directly connected fans may experience relative displacement of the coupling during transportation and installation due to various factors. In order to ensure the normal operation of the fan, the coupling must be inspected and calibrated before the fan runs. The following are several important precautions about couplings:

Firstly, the deviation or radial displacement of the coupling should not exceed the specified value to avoid affecting its transmission performance. Once exceeding the standard is found, it must be adjusted in a timely manner.

Secondly, the bolts of the coupling must be tightened without any looseness or damage. Once any problems are found with the bolts, they should be dealt with immediately to avoid causing larger malfunctions.

In addition, the coupling itself must not have cracks. If there are cracks, they should be replaced immediately to avoid using damaged couplings. You can determine whether there are cracks in the coupling by tapping.

In addition, the keys of the coupling should fit tightly and there should be no looseness. Once the key is found to be loose, it should be repaired or replaced immediately.

Finally, if the elastic ring of the column pin coupling is damaged or aged, it should be replaced in a timely manner. Elastic rings are crucial for the performance of couplings and must be kept intact and undamaged.

Following these precautions can ensure the normal operation of the coupling, thereby ensuring the stable operation of the fan.
