How to maintain a down-hole drilling truck? The editor of Hunan Ruisheng Mechanical and Electrical Equipment told you that the down-hole drilling truck should clean the oil mist and add lubricating oil in a timely manner. The down-hole drilling truck uses an impactor to achieve impact drilling, and good lubrication is a necessary condition to ensure the normal operation of the impactor. Compressed air is usually damp, and pipelines cannot be cleaned properly. After use, a certain amount of water and impurities are left at the bottom of the oil mist atomizer, which affects the lubrication and lifespan of the impactor. If it is found that the oil or oil contains moisture and impurities, it must be removed over time. When adding lubricant, to prevent injury, the entire intake valve must be closed first, and then the collision gas valve must be opened to remove residual gas from the pipe. Lubrication not allowed!

Nowadays, there are a wide variety of washing machines on the market, with varying prices. However, the quality of washing machines produced by different manufacturers varies. So what kind of washing machine do customers need to purchase? When purchasing a washing machine, remember the following points:

DTH drill truck is a semi hydraulic press truck, that is, except for the impact using compressed air, other functions are achieved through the hydraulic system, so the quality of hydraulic oil is crucial to the normal operation of the hydraulic system.
