What is the reason that the oil temperature of DTH Hammer is too high? There are two parts to the overheating of the drilling machine: the oil temperature is too high; the water temperature is too high. Let's talk about these two situations together today. Let's take a look at it together.

　　 The hydraulic oil temperature of the crawler drilling rig is too high:

　　 First, let me talk about the hydraulic oil temperature being too high. According to hydraulic theory and recent repair experience, the main reason for the hydraulic oil temperature being too high is excessive heat generation and slow heat dissipation. The hydraulic pump oil inlet pipeline and hydraulic oil tank are not tightly sealed, the oil inlet filter element is blocked, the hydraulic system pipeline is not dredged, and the internal leakage of the hydraulic pump will cause the hydraulic oil to generate a lot of heat, and the temperature of the hydraulic oil will rise rapidly due to overheating.

　　 The internal passage of the hydraulic oil radiator is blocked, the external dust of the radiator is too large, the wind is not working, and the hydraulic oil does not pass through the hydraulic oil radiator, etc., which may cause the hydraulic oil to heat up too slowly and high temperature.

　　 Crawler drilling rig engine water temperature is too high:

　　 Let me talk about the problem of high engine water temperature. Prohibition of incineration timing, lack of engine power, and failure of the cooling system will cause excessive engine water temperature. On the excavator before the common rail EFI diesel engine, because the hydraulic oil radiator is installed upstream of the cooling air of the water tank, the overheating of the hydraulic oil will also cause the water temperature to be too high. Here are a few examples to illustrate.

　　 In addition, deformation of the crankshaft of the engine and too small crankshaft clearance will also cause high temperature due to the excessive power consumption of the engine itself. Failure of the hydraulic variable control system can also cause excessive engine water temperature.

　　 The temperature of DTH Bit is too high. This is the content mentioned above. You can pay more attention to it in normal use to avoid this situation.
