Characteristics of the external injection single hydraulic prop: The external injection single hydraulic prop has the characteristics of simple structure, convenient maintenance, large initial support force, reliable performance, fast column lifting speed, high working stroke, large working resistance, high working resistance, and good maintenance conditions. When the initial support force of the pump station is ~, the rated working hydraulic pressure is ~ and the rated working resistance is ~. The working medium used is ~ (No.) emulsion. Common faults and treatment methods of external injection single hydraulic props. See the faults. The primary issue in prop maintenance is to ensure the sealing performance of the prop. Due to the influence of underground production conditions and environment, the coating on the sealing surface of the pillar is corroded. High coal dust and ash content cause contamination of the sealing surface or seals, resulting in seal failure and preventing the pillar from performing normal support performance. The three-purpose valve is the heart of the pillar. All functions of the pillar such as lifting, loading, and unloading are guaranteed by the three-purpose valve. Therefore, failure of the three-purpose valve will affect the normal operation of the pillar.
