Drum in a vacuum oil filter

Drum is an important part of vacuum oil filter. And during the design, the screen quality and logistics quality in the drum will be stressed with the centrifugal force of high-speed rotation. The circumferential stress caused by centrifugal force caused by its own mass when the drum rotates at the same time. Rotary drum is also a key factor affecting the performance of vacuum oil filter.

In the vacuum oil filter, the impeller part of the drum is designed integrally. The original impeller USES a closed impeller composed of blades, front and rear leaf covers, the impeller has a high efficiency, but it is difficult to manufacture, and can only transport clean liquid without particles with small viscosity, such as clean water and solution. There is a kind of impeller is half open impeller, it is the disadvantage of: also can only transport less viscous liquid, and the work efficiency is not very high. If you want to transport high viscosity hydraulic oil and other liquids, open blade is a good first choice, can open impeller also less, low efficiency, less application. To sum up, on the basis of the original design of a impeller group containing the upper and lower two impeller, the upper impeller played a secondary transport, secondary separation effect, the coordination of the two impeller also greatly improved the tightness, but also can improve the work efficiency, can also ensure the quality of work.

And vacuum filter oil machine for the design of the blade is optimized, and changed from the original straight blade to now after the curved blade, and from the original type cylindrical to distort, through many experiments and compares with the original, proved that after bending type is twisted blades to improve efficiency, reduce the load of the blade plays a big role, at the same time we also found that inhaled can also increase.
