Crawler transporters also become crawler dump truck, it is very much used, some more complex terrain is used by the crawler transporters. That crawler truck use more, there may be a case of tank fluid overheating, crawler truck tank fluid overheating factors and damage what are they? Let's take a look!

I. Factors of oil heating of crawler transporters

(1) The quantitative pump oil supply system which selects the oil pump capacity according to the fast-forward speed will have most of the remaining flow under high pressure from the overflow valve to overflow back and heat up during operation.

(2) The volume of the oil tank of the crawler truck is too small, the cooling area is not enough, there is no cooling equipment, or there is cooling equipment but its capacity is too small.

(3) High temperature of climate and operating environment, resulting in increased oil temperature.

(4) The unloading circuit in the system is faulty or not set up unloading circuit, the oil pump cannot unload when it stops working, and all the flow of the pump overflows under high pressure, resulting in the loss of overflow and heat, causing the oil to heat up.

(5) The system pipeline is too thin and too long, too many twists and turns, partial pressure loss and large pressure loss along the range.

(6) The hydraulic system operating pressure is adjusted higher than the actual need. Sometimes it is because the seal is too tight, or because the seal is damaged, leakage increases and has to adjust the pressure to work.

(7) Component precision and poor installation quality, the loss of mechanical conflict between the relative motion.

(8) The cooperation gap of the cooperation parts is too small, or the use of wear and tear resulting in excessive gaps, internal and external leakage, resulting in volume loss, such as the volume power of the pump decreased, heating fast.

(9) The selection of oil viscosity is not appropriate, viscosity viscosity resistance is large, viscosity is too small leakage increases, both conditions can form the oil fever.

II. Damage of high temperature of crawler transporters

(1) The viscosity of the oil decreases, leakage increases, and the volume power of the pump and the power of the whole system will drop significantly. Because the viscosity of the oil decreases, the oil film of the sliding valve and other moving parts becomes thin and is cut, and the conflict resistance increases, resulting in increased wear.

(2) Make the rubber seal of crawler truck deformed, accelerate the aging failure, reduce the sealing performance and service life, and form leakage.

(3) Make the crawler truck suffer from thermal deformation, and the moving parts with different thermal expansion coefficients in the hydraulic components become stuck due to the small gap in their cooperation, resulting in action failure, affecting the transmission accuracy of the hydraulic system, resulting in poor quality of operation of the components.

(4) Make the air separation pressure of the oil drop, the dissolved air in the oil escape, the onset of cavitation, resulting in a decline in the operating performance of the hydraulic system.

(5) Accelerate the oxidation and metamorphosis of the oil, and the separation of asphalt substances, reducing the service life of the hydraulic oil. The separation of the material blocked damping pores and gap-type valve mouth, resulting in pressure valve stuck and can not move, metal pipe elongation and bending dian, and even rupture.
