What is the reason for the high oil temperature in the drill
The high temperature in the drilling rig is generally divided into the high temperature of the gearbox, the high temperature of the hydraulic oil, and some are the high temperature of the engine cooling liquid. In fact, the reason for the high temperature of the gearbox is very simple. The main reason is that the size and shape of the bearing or gear and housing are not standard or the oil is unqualified. Now let's give you a detailed analysis.
First of all, the temperature of hydraulic oil is too high. According to hydraulic theory and maintenance experience in recent years, the main reason for the high temperature of hydraulic oil is too fast heat generation and too slow heat dissipation. The oil inlet pipeline and hydraulic oil tank of the hydraulic pump are not sealed tightly, the oil inlet filter element is blocked, the hydraulic system pipeline is not unblocked, and the internal leakage of the hydraulic pump will cause a large amount of heat to be generated in the hydraulic oil, so that the temperature of the hydraulic oil will rise rapidly due to excessive heat generation.
