With the maturity of the mud-free market, more and more customers are using GN solid-control vertical cutting dryers. Since the dryer is a high-speed operation equipment like decanter centrifuge, it requires high internal parts and it is especially important to carry out necessary maintenance and maintenance on a regular basis. The following is a brief introduction to the daily maintenance and maintenance of the dryer.

 

After the first use of the dryer for half a month, the new oil should be replaced. Every other month, the oil filter net is cleaned with kerosene once, and the oil contamination and deterioration are checked. The oil change time is determined according to the oil quality. The maximum length cannot exceed six. Months. When replacing the new oil, the oil pipe, oil filter net and fuel tank should be cleaned. If the oil filter net is worn or damaged, replace the new oil filter net and check the tightness of the oil pipe. Check the oil level every two weeks (through the oil mark), and add new oil when the oil quantity is insufficient.

The main motor and oil pump motor are lubricated separately with grease. The motor grease is replenished every 2,500 hours. The grease is recommended according to the manual.

During the working process, if the oil temperature is too high, the oil pressure is low or high, and the oil quality is deteriorated, stop the machine immediately.

Inspection and routine maintenance

Daily routine inspection content:

 

  1. Whether the vibration of the dryer is abnormal;
  2. The temperature of the main bearing, normal temperature T ≤ 90 ° C;
  3. Whether the screws of each component are loose;
  4. Whether the slagging and slurrying conditions and the slurry line leak slurry, and whether the inlet and outlet are blocked;
  5. Whether the lubrication system has oil leakage or abnormality.

If there is any abnormality in the above inspection, it should be stopped immediately for processing.

 

Check the content regularly:

 

  1. Check the tightness of the narrow V-belt every 1000 hours of operation, too loose to adjust; wear should be replaced;
  2. Every 1000 hours of operation or excessive vibration, check whether the parts of the equipment are loose, check whether the sensors are connected reliably;
  3. Every other month, the oil filter is cleaned with kerosene once, and the oil contamination and deterioration are checked. The oil change time is determined according to the oil quality, and the maximum time cannot exceed six months;
  4. Check the oil level every two weeks (through the oil mark), and add new oil when the oil quantity is insufficient;
  5. Push and pull the scraper handle every two hours to prevent slag.

In addition, if there are special circumstances, it is necessary to stop the inspection in time to find the cause of the problem and avoid further spread.
