1. In the free state, the inner diameter of the oil seal lip is smaller than the shaft diameter and has a certain amount of interference.
2. After installation, the interference pressure of the oil seal edge and the contraction force of the self-tightening spring generate a certain radial pressure on the rotating shaft.
3. When working, the seal lip forms a 0.25 to 0.5 mm wide seal contact ring under radial pressure. Under the effect of lubricating oil pressure, oil penetrates between the edge of the oil seal and the shaft to form a very thin layer of oil film. The oil film is affected by the surface tension of the oil. A “crescent†surface is formed along the outer edge of the shaft and the edge of the oil seal to prevent the oil from overflowing and play a sealing role.
Pocket spring mattress making machine is fully automatic nc operation. As a result of the use of back sealing ultrasonic edge sealing.In the production of thicker steel spring can also be used in a thinner non-woven fabric. With empty cutting part length setting and cloth consumption automatic stop and other functions. Thus improves the intelligence of the machine, so that the production of the product cost is lower, less waste, the structure is more solid, is independent bag bed mesh and sofa seat package ideal equipment.
Features:
1.It can produce drum, straight drum spring.
2.Connection function of non-woven fabric, saving fabric and loading time.
3.Reliable heat treatment system, quick and convenient adjustment.
4.Each station is equipped with detection and alarm device, which makes the fault clear and convenient to deal with.
5.The spring relief system has been improved, compared with the same industry machine,more safe and reliable operation.
6.The wire delivery system has been improved, compared with the same industry machine, more safe and reliable, not easy to mess.
7.Full servo precision control, greatly reduce the amount of gas used and reduce the maintenance rate of pneumatic components, more stable operation.
8.More user-friendly procedures,more safe and stable operation.
