In such conditions, the load on the engine is minimal, and wear of the drill bits occurs slowly. Operators note the smooth operation and absence of jerks during feeding, which has a positive effect on the quality of the drilled well.
The situation changes dramatically when reaching boulder deposits or rock formations. This is where the overload protection system comes into play, automatically releasing pressure at critical resistance. Some users complain about frequent stops of the automation when drilling in heterogeneous soils, considering this to be a drawback of sensitivity settings. Others, on the contrary, see this as an advantage, since the system prevents damage to expensive drilling tools and spindles.
To work in clayey, viscous soils, it is necessary to correctly select the parameters of the flushing fluid. Installation Burka prosp equipped with a pump for supplying flushing, the performance of which is usually sufficient for standard tasks. However, when deep drilling in sticky clays, artificial liquefaction of the solution or the use of an air hammer is sometimes required, if the equipment of the machine provides for this. Experienced drillers recommend not to force the feed in such soils to avoid tool jamming.
Frequent malfunctions and methods for eliminating themDuring long-term operation, owners Burka prosp Selmash 2 encounter a number of typical faults, knowledge of which helps to minimize downtime. The most common problem is overheating of the hydraulic oil, especially in hot weather or when operating at maximum speed. Often the reason lies in contamination of the cooling radiator or failure of the thermostat. Regularly cleaning the radiator and replacing the fluid will help avoid loss of performance and damage to the seals.
Another vulnerable point is the oil seals and rotator seals, which are subject to intense wear due to the abrasive effects of drilling dust. When the first signs of oil leakage appear, it is necessary to replace the cuffs, otherwise dust will get inside the mechanism, which will lead to scuffing of the shafts. In the model Selmash 2 Access to these units is somewhat difficult, which requires special tools and qualified maintenance personnel.
Problems with the electrical part are most often associated with oxidation of contacts in conditions of high humidity or dust. Pressure and position sensors may give incorrect readings, which leads to incorrect operation of the automation. For diagnostics, you must have a multimeter and an electrical connection diagram on hand. Regular tightening of terminals and the use of protective sprays on contacts significantly reduce the risk of sudden electronic failures.
☑️ Diagnostics before shift
⚠️ Attention: If metal shavings are detected in the hydraulic oil, immediately stop work and troubleshoot the pump group, as this indicates the beginning of destruction of the friction pairs.
