We are specialized in making single hydraulic prop. We not only have advanced production equipment, perfect processing technology, and responsible staff, we can work together to ensure the quality of single hydraulic prop. Our personnel have high professional knowledge. I will give you this article. Introduce the management method of the single hydraulic prop.
1. First, train a full-time team for the use, handling, management, and maintenance of suspension hydraulic prop, improve management procedures, and establish a management responsibility system and inspection system. Carry out the count and verify the quantity carefully, and prosecute and punish those who cause serious damage or loss during use and disposal.
2. In the course of use, if there are the following situations, the suspension hydraulic prop must be repaired and immediately lifted: automatic unloading of the descending hydraulic acrow props, the pillars will not fall after the active pillars; the unloading mechanism has been built; the hydraulic acrow props are significantly deformed or significantly damaged; the bottom row is lowered The living pillars contract and the pillars form a support to die.
3. The hydraulic acrow props used in the working face should be intact, and the completion rate should not be less than 90%.
4. After use for more than 8 months, for maintenance and lifting of the well and lowering the suspension hydraulic prop; once the props are damaged or temporarily downhole, the well will be delivered to the well for maintenance and repair in time to increase the use turnover rate and reduce the production cost.
5. All single hydraulic prop must be cleaned, cleaned, repaired and cleaned of coal dust, etc., corroded by pitted pillars, galvanized and phosphated: the three-purpose valve that has been used for a long time, the sealing ring is aging, and there is serious leakage, it must be removed for inspection and replacement Seal ring.
6. After maintenance, the single hydraulic prop is used for high and low voltage, voltage test, and after the acceptance criteria, it can be put into use again.
7. In order to ensure the normal production of the working face, there must be spare coal hydraulic acrow props in the working face, and the total coal pillar usage must reach more than 10% of the total working face stars. It is neat and safe, dry, and Qingpu near the working face. Where: The mining height of the working face is quite different, and the coal reserves and coal twisting specifications increase correspondingly.
8. Idle speed can not be repaired in the open storage of the support pole to store in a sorted air-drying at higher than 0cI = repair shop or warehouse at room temperature.
9. When maintaining a single hydraulic prop, follow the single hydraulic prop maintenance regulations.
