There are many problems with the vibrating screen machine. Today, I will tell his family the key points of maintenance and repair.
Weekly inspection, monthly inspection and annual inspection can be carried out.
Weekly inspection
Check whether there are cracks in the welding parts or other parts of the screen body, the mesh of the sieve plate is blocked, and the sieve plate is worn, if any problem is found, it should be handled in a timely manner.
Monthly inspection
Check whether the screen frame component itself or the welding part has cracks. If there are cracks, the surface shall be cleaned. Drill holes at crack ends Φ 5 mm. The groove shall be chipped out and preheated before repair welding. The penetration shall be ensured. After welding, the weld shall be ground flat, and then the reinforcement plate shall be added.
yearly inspection
The exciter shall be cleaned and overhauled. When disassembling, pay attention to making the same mark on the inner ring of the bearing and the bearing body, and strictly prevent the inner ring from being mistaken with the original bearing during assembly after cleaning, to keep the original clearance of the bearing. If bearing pitting is found, replace the complete set of bearings.
lubrication
The vibration exciter is lubricated with thin oil, and the oil shall be changed after 40 hours of initial operation. The oil change cycle is 120 hours in normal use.
The oil filling quantity can refer to the vibrator oil filling gauge. A small amount of oil can be continuously dripped out. The lubricating oil is GB13895-1992 heavy load vehicle gear oil with the brand of GL-5.
Inject GB7324-1994 general lithium base grease into the labyrinth groove between the sealing plate of the vibrator and the isolation ring. The grease brand is No. 3. During grease injection, aim the grease gun at the oil cup and inject grease every 15 days. Inject 50-100ml at each point.
According to different types of vibration exciters and bearings, oil shall be injected regularly as required, and the vibration exciter bearings shall be cleaned once a year to ensure good lubrication.
The side plate of TSX vibrating screen is designed with seamless hydraulic tension, which is not easy to crack. The vibration exciter uses SKF special bearing, which has long service life and smooth operation
