　　1YN30A internal combustion rock drillintroduction：

　　Gasoline internal combustion rock drill is a handheld rock drilling tool powered by fuel combustion, which is composed of a small gasoline engine, compressor, and rock drill. It is mainly used for drilling boreholes with a downward, horizontal, and upward angle of less than 45 degrees, replacing a few parts, and can be changed to a crusher or compactor for various tasks such as shoveling, crushing, excavating, splitting, and compacting. Due to its inherent power, the machine produces compressed air to blow and clean the blast holes, making it particularly suitable for areas with high mountains, no power supply, no compressed air equipment, and temporary projects with high mobility.YN30A internal combustion rock drillWidely used in open-pit mining, excavating frozen soil, road construction, cable laying, and water conservancy construction.

　　IIYN27C internal combustion rock drillworking principle

　　YN27C internal combustion rock drillIt is a new type of rock drilling machinery powered by low-power internal combustion engines (mostly two-stroke gasoline engines), suitable for field operations without power and air compressors. According to work requirements, internal combustion rock drills are generally equipped with more than ten types of tools (such as grinding wheels, picks, shovels, shovels, etc.) in addition to rock drilling operations, which can be used for crushing, chiseling, excavating, splitting, compacting and other operations.

　　3、 YN30A internal combustion rock drillIt is a tool used for directly mining stone materials. It drills boreholes in rock layers to insert explosives to blast open rocks, thereby completing the extraction of stone or other rock engineering. In addition,YN30A internal combustion rock drillIt can also be used as a disruptor to break hard layers such as concrete.

　　4YN30A internal combustion rock drilltroubleshooting

　　The fuel used for internal combustion rock drills is 70 octane gasoline and 15 octane gasoline engine lubricating oil, which should be strictly matched in a volume ratio of 12:1, and the fuel and fuel tank should be kept clean. When the machine malfunctions, the first thing to check is the oil circuit.

　　There are two reasons for excessive fuel intake: one is that the throttle needle valve is too wide open; The second reason is that the air filter is clogged with dust, a check valve has too much elasticity, or the throttle valve opening is too high.

　　When starting according to the normal starting method and steps, if the rope cannot be pulled up several times and a lot of oil mist is sprayed from the exhaust pipe, it indicates that too much oil has been injected. At this point, the needle valve should be closed, the air blocking valve should be opened, and the power cord should be pulled up several times to drain the excess oil from the engine until the ignition makes a "bang bang bang" sound. Then, open the throttle and start the engine again. If there is still oil mist spraying out and it cannot be started, check whether the air filter is blocked and whether the elastic force of a check valve plate is too strong. Because this will reduce the intake of air into the engine and increase the intake of fuel, resulting in an improper mixture ratio of fuel and air, causing difficulty in starting or low engine speed, resulting in weak operation. At this point, the air filter should be cleaned, or the elasticity of the check valve plate should be appropriately reduced, and the sealing should be maintained.

　　The opening height of the throttle valve is too high, which will also cause improper mixing ratio of air and fuel, resulting in high engine speed, asynchronous movement of the upper and lower pistons, and uncoordinated work, reducing the rock drilling speed. It will also cause the engine to run intermittently. At this point, adjust the opening height of the throttle valve to 9-10mm.

　　In addition, excessive fuel intake not only causes fuel waste, but also accelerates carbon deposition inside the machine, increases machine temperature, reduces machine performance, or causes self parking, making it difficult to restart. So, the larger the oil intake of the internal combustion rock drill, the better. After starting, it is advisable to turn the throttle to about one circle.
