For us, regarding the daily maintenance of the negative pressure fan, this is also an important task and content, because it is related to the use effect and service life of the product, so it can not be sloppy to avoid problems. And brings bad or serious consequences, so that the negative pressure fan can not be used normally.

The negative pressure blower, its daily maintenance work mainly has the following content, its concrete is:

Work content 1: Clean the protective net in the negative pressure blower. If there are impurities on it, it should be promptly removed.

Work content two: Inspect the belt in the negative pressure fan, mainly to see if the tightness is appropriate. If it is not appropriate, it should be adjusted in time to make it suitable.

Job Description 3: Check motor bearings for vibration or noise during operation. In addition, whether it is sufficient and in place in lubrication.

1. Maintenance and repair of negative pressure blower damper

(1) For the damper in the negative pressure blower, the following maintenance and repair work will be carried out by the Wuxi negative pressure blower manufacturer Hulin, so that everyone can master it well.

(2) Check the tightness of the belt. Turn the wind wheel by hand to see if it turns smoothly. In addition, necessary inspections and replacements are performed for gaskets and seal packings on each joint surface.

(3) For motor rotors, filters, and interiors, check and cleaning work should be performed. If there is rust, or paint is peeled off, it should be repaired in time. In addition, for the rotating parts of the negative pressure fan, sufficient lubrication should be performed to ensure the stability and flexibility of the coupling and the bearing.

2. Maintenance of electrical circuit in negative pressure fan

For this, the recommendations of the vacuum fan manufacturers are:

For the mechanical opening and closing of the regulating valve, check whether it is flexible and whether the corresponding mark is clear. For instrumentation, it is to see if it can be used and displayed normally. For components in the control box, see if there is an exception. In addition, the suction fan was commissioned for two hours to check if the temperature rise of the bearings and the motor was normal.
