Working Principle of Portable Handle Yn27c Drilling Rig
The internal combustion rock drill is a new type of rock drilling machine powered by a low-power internal combustion engine (mostly a two-stroke gasoline engine), which is suitable for field operations without a power supply and air compressor. According to the work needs, in addition to the rock drilling operation, the internal combustion type rock drill is generally equipped with more than ten kinds of tools (such as grinding wheels, picks, shovels, shovels, etc.), which can be used for crushing, shoveling, digging, splitting, tamping and other operations.
Description of Portable Handle Yn27c Drilling Rig

5. First-class level Drilling Tools, are suitable for sites without power or air pressure equipment, it has wide adaptability for high mountains and plains, and extreme temperature (±40ºC).
Causes of Oil Circuit Failure
The fuel used by the internal combustion rock drill is No. 70 gasoline and No. 15 gasoline engine lubricating oil. The two should be matched in strict accordance with the volume ratio of 12:1, and the fuel and fuel tank should be kept clean. When the machine fails, the first thing to check is the oil circuit. There are two reasons for too much oil intake: one is that the throttle needle valve is opened too much; the other is that the air filter is blocked by dust, the first check valve is too elastic or the throttle valve is opened too high.
