3. The speed of the pump is too high, in the metallurgical industry or heavy medium coal preparation containing large particles, the speed is too high, which will greatly shorten the service life of the pump flow parts, cause the user to increase the cost, on-site maintenance frequency and other problems.
4. Reliability Built with robust components, portable rotary air compressors are designed to withstand tough working conditions. They require less maintenance and have longer service lives, resulting in cost savings over time for users.
2. Acier allié Pour des applications nécessitant une résistance accrue à la fatigue et à la corrosion, des barres de forage en acier allié peuvent être utilisées. Ces alliages contiennent des éléments tels que le nickel, le chrome et le molybdène, qui augmentent leur résistance et leur longévité.
