LSY 219mm Diameter Seamless Pipe Tubular Screw Conveyor With Hanger Bearing
Screw conveyor, commonly known as auger conveyor, is a kind of conveying equipment with a wide range of uses in the mining, feed, grain and oil, and construction industries. It is divided from the perspective of the displacement direction of the conveyed material. The screw conveyor is divided into horizontal screw conveyor and vertical screw conveyor. There are two main types of machines, mainly used for horizontal conveying and vertical lifting of various powder, granular and small lumps and other loose materials.
Characteristics are below:
1. Large bearing capacity, safe and reliable
2. Strong adaptability, convenient installation and maintenance and
long service life
3. The whole machine is small in size and high in speed, ensuring fast
and uniform delivery.
4. The discharge end is equipped with cleaning device, which has
low noise, strong adaptability and flexible layout of inlet and
outlet
5. Good sealing, the shell is made of seamless steel pipe, and the
ends are connected with each other by flanges, and the rigidity is
good.
The screw conveyor uses the rotating screw to move the conveyed material along the fixed casing to carry out the conveying work. The head and tail bearings are moved to the outside of the casing. The hanging bearing adopts a sliding bearing and is equipped with a dust-proof sealing device. The bearing bush is generally used Powder metallurgy, the conveying cement adopts felt bearing bushes, and the suspension shaft and the screw shaft are connected by sliding blocks.
1. The center line of the trough and the screw shaft should
maintain good coaxiality.
2. The joints between the sections of the trough should be tight
and there should be no misalignment. Gaskets can be added between
the sections and between the top cover and the trough to ensure the
sealing of the trough. At the same time, the length error of the
trough can also be adjusted.
3. The gap between the inner wall of the trough and the spiral body
should be equal.
4. The drive shaft and the screw shaft should maintain good
coaxiality. When adjusting, the height of the drive device can be
adjusted with the help of a spacer.
5. After the spiral body is installed, a static balance test should
be carried out.
6. The intermediate suspension bearing should reliably and properly
support the connecting shaft to avoid radial deformation of the
screw shaft. The installation can be achieved by adjusting the
gasket between the bearing bushes.
7. After the whole machine is installed, check whether there is any
sundries in the machine and whether all lubricating places are
filled with enough lubricating oil.
8. During the no-load test run, the bearing should not leak oil,
and the bearing temperature rise should not exceed 20°C. During the
load test, the bearing temperature rise shall not exceed 30°C.
