To prevent the gearbox from leaking oil again, you can replace the two-part skeleton seals. In addition, check whether the gearbox and the lubricating oil meet the specified requirements, whether the oil level is too high, and whether the breather port is unobstructed. If no abnormalities are found, you can proceed with the normal replacement of the lubricant.

If the motor and gearbox temperatures are too high, it could be due to sluggish rotation of the scraper assembly or oil leakage. You can perform the troubleshooting steps described above.

If there’s a problem with the internal structure of the motor or reducer, you can consult us. Graphite flotation equipment Professional technicians from the manufacturer will carry out the repair.

Common faults of drying chambers

Common faults in the drying tank of graphite flotation equipment typically occur during the equipment installation phase—specifically, there may be some degree of leakage and water seepage at the fixing points, and in certain welded areas along the safety passages at the bottom of the tank.

Fault Detection and Removal:

1. The sealing gasket on the surface of the drying chamber’s connecting sleeve must be thoroughly secured and free from deformation. Apply sealant to the flange surfaces to enhance the seal. After ensuring a tight connection at the joint surface, tighten the torque bolts.

2. If you detect a leak in the gap of the well-connected drying chamber, first check whether the anchor bolts are loose and whether the rubber sleeves are damaged. Try loosening and tightening the anchor bolts to relieve stress, then reapply sealant around the screws, rubber sleeves, and inspection gaps, and finally retighten the anchor bolts.

3. If the location and direction of the leak are uncertain, or if the actual operation fails to produce satisfactory results, you can try fully sealing the area around the surface flow plate on the graphite flotation equipment, or continuously improve the weld quality around the leakage points at the joint surfaces to address the water leakage issue.

Common Faults of Gate Valves

The gate valve is located at Graphite flotation equipment At the tail end, the structure is relatively simple and is primarily used for level gauges in tank troughs. This equipment undergoes frequent installation, commissioning, and usage, making it prone to common failures such as main shaft damage and water leakage.

Fault Detection and Removal:

1. Under the condition that the lead screw lubrication is confirmed to be excellent and there is no damage to the rubber sleeve, pay special attention to the torque levels of special screws.

2. The rubber sleeve must be firmly bonded to the back side of the gate valve, with a smooth and even surface. Assemble the gate valve only after the rubber sleeve has completely dried.

3. The special screws are designed based on the selected options and cross-sectional dimensions. After tightening the torque, the natural axial force between the gate valve and the U-shaped plate of the drying chamber should meet the design specifications. If no unexpected situations arise, avoid making adjustments; otherwise, if the torque is too loose or too tight, it could lead to water leakage.

The above are the four most common types of equipment failures encountered in foot-operated flotation machines. In the actual production process, it is important to emphasize the cultivation of... Graphite flotation equipment Daily maintenance and maintenance awareness require maintenance personnel to master the principles of flotation machines and their troubleshooting characteristics, enabling them to carry out effective maintenance and extend the service life of flotation machines. It is recommended that mining sites, when making purchases, select flotation machine manufacturers that can provide equipment installation, commissioning services, and ongoing technical support, thereby preventing equipment failures from the very outset.
