The running-in pad is widely used in mining lifting equipment. So, what is the role of block objects of different colors in lifting equipment? The following import liner manufacturers talk about the role and importance of running-in liner.
Imported liner
a) Guarantee factor
The running-in lifting equipment uses the power of running-in and steel ropes to lift heavy objects and people. The coefficients vary depending on the pad material. It is an important part of running-in lifting equipment. The weight of all ropes, the weight of the container, the load weight, the weight of the balance tail rope, and the various loads and shock loads during operation must have sufficient compressive strength. In order to prevent slippage during hoisting, there must be sufficient coefficient with the steel rope.
b) Protect the steel rope
It has a good protective effect on the steel rope. Macroscopically, the imported liner manufacturers believe that on the premise of ensuring the support strength, the softer the material is, the more favorable it is for the steel rope.
The coefficient is the most important factor for the sliding interaction with the steel rope. After the wrong coefficient of running-in is selected, the interaction force decreases, resulting in relative sliding, and at the same time, the loss of the steel rope is too fast. Imported gasket manufacturers consider loss as a variety of factors, and analyze the influence of coefficients on coefficients to better prevent and reduce loss, thereby prolonging service life.
The coefficients are divided into coefficients when the rope is dry, coefficients when wet, and coefficients when lubricated. The coefficient on the capstan is related to the rope pressure of the steel rope. The imported pad manufacturers believe that the various coefficients are also different when the pressure of the steel rope is different. Our company's long-term tests and experience show that the coefficient value of WK868 high-performance friction lining can reach 0.41 in a dry environment, and can reach 0.6 in the state of water and grease. The coefficient of 0.25 required by the running-in type lifting equipment can always keep the coefficient of the running-in type lifting equipment above 0.25. Therefore, the imported pad manufacturers believe that accidents such as slipping ropes are not easy to occur.
Improper use of the coefficient will cause the container to enlarge and slip, so the running-in pad with the appropriate coefficient must be used according to the working conditions.
Imported gasket manufacturers share the following features:
1. The coefficients under various working conditions are all greater than 0.25. It fully meets the use requirements of multi-rope running-in lifting equipment.
2. The liner is a material with high mechanical strength and will not damage the steel rope, and it is easy to machine the groove of the rope on site.
3. The test results show that the heat resistance, melt resistance and loss are better than those of the K25 import, and the equal power loss is the same as that of the K25 import.
4. Good compatibility with running-in grease. Both imported and domestic running-in grease are applicable.
5. The skywheel has stable guiding performance, strong reliability and reasonable price, which can bring considerable economic benefits to users.
