The disadvantages of traditional automatic refueling:
1. Refueling is not in place. The traditional way of refueling cannot directly add oil to the inner bladder and chute of the core part of the rotary hook.
2. The fuel flow cannot be precisely controlled. Too much will be thrown on fabrics, machines, and ground to cause pollution.
3. Uneven distribution of fuel. The distribution of each head from the head to the tail is not in place, the amount of organic head oil is too much, the amount of organic head oil is too small, and individual heads may even not produce oil. The more the number of heads, the greater the problem.
4. Oil leakage. The aging of the filler pipe joint or installation problems will cause oil leakage for a long time, directly causing the function to be unavailable.
5. Blockage. Long-term storage of oil in oil pipes and oil tanks will deteriorate, and the deteriorated oil will block the oil holes like sludge.
