Check whether the oil content in the condensate discharged from the drain valve of the Kaishan air compressor is too high, whether the oil level of the compressor is too high, whether the opening pressure of the small pressure valve is normal, whether the return oil pipe is blocked, and whether the oil separation core is blocked.
[pdf] The reasons for the high exhaust temperature of screw air compressors : 1. High return air temperature; 2. The motor has a large heating capacity; 3. High compression ratio; 4. High condensation pressure; 5. Improper selection of refrigerant.
[pdf] Sonic drilling employs a high frequency, rotary vibratory drill that is designed to fluidize, overburden, and fracture rock faces. This process results in seamless casing advancement or continuous core samples that can be accessed without the application of drilling fluids.
