M6-31、 7-16 type coal powder fan

The M6-3l and M7-16 coal powder centrifugal fans are newly sold products by our company, which have the advantages of energy saving, low noise, good airflow stability, flat performance curve, wide range, compact structure, and easy maintenance. Generally, the high temperature should not exceed 80 ℃. If the performance is suitable, it can also be used for other applications.

The M6-3l and M7-16 coal powder centrifugal fans are new products that replace the old fans M9-26, M7-29, and M9-27, and add high pressure zone performance for small and large flow rates.

structural characteristics

1、 Wide operating range

The M6-3l and M7-16 coal powder centrifugal fans consist of two series of products, M6-31 № 12-20D and M7-16 № 14-20D. Each series of products is standardized to have a machine number every 50mm, with a total of 30 specifications, making it easy to operate under different working conditions.

2、 Good flow stability

The M6-3l and M7-16 coal powder centrifugal fans have backward plate blades with good flow stability and the motor is not easily overloaded.

3、 Can it be good

The M6-3l and M7-16 coal powder centrifugal fans have good flow stability, reducing the impact of airflow and medium on the blades.

4、 New type bearing box

The bearing box is lubricated with a thin oil pool, using a lap type oil slinger ring, a semi open aluminum oil seal, and a ventilation cover to reduce the slight positive pressure inside the bearing box and prevent oil leakage.

5、 Attachment matching

M6-3l and M7-16 coal powder centrifugal fans are equipped with inlet and outlet pipe side flanges, coupling guards, and foundation bolts for fans and motors.

6、 Regarding parameter provision

Fan rotor, overall weight, static and dynamic loads, rotor moment of inertia, and external dimensions. Holding the sample is sufficient for construction.

7、 There are few molds used for fan manufacturing and maintenance.

8、 Adopting new achievements has improved the service life of the fan.

l、 The welding electrode specially developed for fans has been tested by a wear tester and is 3-5 times higher than 16Mn material.

2. This welding rod is very convenient to operate, and the base material does not need to be heated. It can be formed by welding with a general electric welding machine.

3. Due to the different processes of each system, the wear parts are also different. Therefore, before the fan leaves the factory, the general parts are welded (if the user specifies the accurate wear parts, the fan can also be arranged before leaving the factory). After a period of on-site operation and maintenance, the user will weld according to the actual wear parts to extend the service life of the fan.

9、 Strong processing

When the working condition medium causes severe wear on the fan, special negotiations can be made to use spraying, chemical treatment, or materials such as silicon carbide and limestone for treatment.

10、 Simple manufacturing and easy maintenance

Due to the straight blades, flat front disc or conical disc, and conical air inlet, the straight air inlet makes manufacturing and maintenance very convenient. Repair materials can also be provided.
