Default Bearing the structure improvement of urea granulator

Once change the sealing ring to laminate and an increase in the thickness of the ring, aiming at the problem of the original seal ring.Bearing the structure improvement of urea granulator
But did not receive the desired effect. To do this, change the seal plate to carbon fiber ptfe sealing packing.

Use the outline of belt pulley device packing gland, granulator's bottom sealing structure to upper packing seal structure.
Such as for observation, the running status and facilitate maintenance, mostly used the compression packing seal, effectively prevent the leakage of urine.
2.2 hollow shaft
Design of a hollow shaft, in order to meet the requirements of sealing structure.Bearing the structure improvement of urea granulator
The SKF Bearings adopts a 127 0 crl7nil4mo2 mm17mm data high pressure tube processed (figure 4 upper pulley and the shaft seal packing, lower through the screw thread connection a convex flange with type I shower nozzle is linked together, thus turns the nozzle, this not only ensure the nozzle rotating coaxial degree, and ensure the nozzle flange sealing is reliable. Bearing type query software
2.3 the bearing arrangement
Pelleting machine design at the bottom of the device is a 8222 thrust ball bearing, in order to improve the force of the rolling bearing.
Through it to accept the center pipe, pulley, nozzle, and urine of axial load.

In top and bottom of the pelleting machine design at the same time the two bearing seat, the two bearing seat connected with the body fit, replaced the original bearing end cover, both to ensure the bearing with the device, and ensure that the whole of the granulator with assembly, as well as storage of lubricating oil.Bearing the structure improvement of urea granulator
2.4 lubrication structure
Pelleting machine design of the assembly, the upper and lower two oil due to adding the upper and lower bearing seat. Combination of upper and lower bearing seat. Bearing the navigation

On the upper and lower bearing seat design respectively for two with the same lubricating oil filling joints, when the lubricating oil by oil gun from injection, oil injection joint through the lubricating oil into the bearing seat, with the rotation of the bearing, bearing and lubrication.
Considering the lubricating oil will continue to drain, felt seal instead of the original bearing end cover skeleton oil seal, greatly reduce the loss of the lubricating oil, to ensure the long term operation of the equipment.Bearing the structure improvement of urea granulator
