What factors affect the lifespan of steel wire braided rubber hoses
Time:2024-01-24Page views:1166Steel wire braided rubber hoses are mainly used for soft connections between various equipment, with high bending performance and a wide range of applications. It can be used not only in industry and agriculture, but also in many fields such as chemical engineering. At the same time, it has relatively low requirements for the working environment, so it often replaces traditional rubber hoses for more complex and harsh environments. So what are the factors that affect its service life?
1. Rubber hose material
Generally speaking, rubber hoses made of natural rubber have a longer service life, followed by EPDM rubber, and then nitrile rubber. If you want to extend the service life of the hose, you need to choose the appropriate material according to your usage needs.
2. Transmission medium
In addition to the compatibility of the conveyed medium, the temperature of the medium also affects the lifespan of the hose. If the temperature is too high, the service life of the hose will be reduced due to accelerated aging. Therefore, during use, it is necessary to determine the operating temperature of the rubber hose.
3. Compression method
In terms of the degree of damage to the rubber hose during the compression process, the larger the diameter of the pressure roller, the better, but the degree of damage to the smaller diameter is also significantly lower than that of the sliding shoe. Of course, compressive strength is also an important factor affecting the service life of rubber hoses. Excessive compression usually increases the load on the bearing and consumes more energy, while insufficient compression can cause internal leakage and backflow, while reducing volumetric efficiency. According to statistics, as long as one centimeter is excessively compressed, the service life of the hose will be reduced by 25%.
4. Pump speed and lubricant usage
This mainly applies to the rubber hoses used in industrial hose pumps, and the pump speed is one of the important factors affecting the service life of steel wire braided rubber hoses. Generally speaking, doubling the speed will reduce the service life by half, and vice versa. Of course, regularly adding lubricants can also increase the service life of the hose.
Many conditions are not like this, and there are still many conditions that determine the length of its service life, such as whether the steel wire braided rubber hose is frequently bent during use, which can also affect its service life. In addition, with the increase of compression times and long-term wear of the hose, it will also be unable to continue using due to excessive fatigue.
