Four main factors affecting the service life of industrial hose
Nov 21, 2017

First, hose material. Generally speaking, the natural rubber material Hose service life is the longest, followed by EPDM, and finally nitrile. To prolong the life of the hose, you have to choose the right material as needed.

Second, the transmission medium. In addition to the compatibility of the transport medium will affect it, the temperature of the medium can also greatly affect the life of the hose. If the temperature is too high, the hose will reduce the service life due to accelerated aging. Therefore, the use of the process, to choose the appropriate temperature.

Third, the compression method. In terms of the degree of damage to the hose, the diameter of the pressure roller is good, but the damage degree of the small diameter is obviously lower than that of the Slipper. Of course, the intensity of compression is also an important factor affecting the service life of the hose. Excessive compression often increases the load on the bearing and consumes more energy. And the lack of compression will also generate internal leakage of the situation, while reducing the efficiency of the volume. According to statistics, only an excessive compression of one centimeter, will reduce the hose 25% service life.

IV. Pump speed and lubricant use. This is mainly aimed at the hose used in industrial hose pump, the speed of the pump is one of the most important factors affecting the service life of industrial hose. Generally speaking, increasing the speed of one-fold will reduce the service life of half, and vice versa. Of course, the regular replenishment of lubricants can also improve the service life of the hose.
