Agricultural crawler truck is used for agricultural transport machinery and equipment, agricultural crawler truck is suitable for river banks, paddy fields, tropical rainforests, snow and ice and other complex road conditions, but agricultural crawler truck use for a long time, there will be some failures, some customers will ask, crawler truck hydraulic system overheating how to do? We first need to find the hydraulic system overheating factors. The following is a summary of the reasons for the overheating of the hydraulic system of the agricultural crawler truck.
1, Crawler truck hydraulic oil selection improper or poor oil quality leads to high oil temperature: oil viscosity is too high, resulting in excessive loss of fluid flow pressure, converted into heat, will lead to high temperature rise; oil viscosity is too low, will also lead to the operation of hydraulic pumps and hydraulic components within the leak large, heat; in addition, some poor quality fluid, viscosity temperature function is poor, easy to emulsify and produce cavitation, fold out bubbles, etc., will occur in the hydraulic oil high pressure local High temperature and aggravate the wear of components, so according to the system load and normal operating temperature requirements, choose the appropriate viscosity of the hydraulic fluid. Reasonable choice of hydraulic oil, especially the viscosity of the fluid, in the case of conditions, try to use a lower viscosity to reduce the loss of viscosity conflict.
2, Regularly check the height of the hydraulic oil in the hydraulic oil tank, long-term operation has some, always keep the hydraulic oil surface height in the normal oil level range, and then ensure the role of the oil tank heat dissipation.
3, Found that the cooler blockage, to be timely finishing to ensure the cooling effect of the cooler.
4, The hydraulic system is not smooth, the conflict formed by the large fever. Solution to add hydraulic oil, reduce conflict loss.
5, Environmental problems, the surrounding temperature is high so that the oil temperature starting point is high, and also not easy to dissipate heat. Solution to add heat dissipation efforts to progress the cooling effect, or increase the hydraulic oil tank.
6, Long-term use of hydraulic oil formation of impurities in the hydraulic oil, hydraulic oil pollution so that the motor, multiway reversing valve, hydraulic cylinder and other hydraulic components or seals to accelerate wear, and then the formation of hydraulic oil temperature rise. The solution is to replace the hydraulic oil regularly.
7, Crawler truck long-term operation, improper operation or long-term walking: continuous long-term operation under high pressure and power, the main safety valve or secondary overload relief valve is frequently open, the hydraulic system in the oil circuit and components due to long-term high pressure and the fluid heating.
These are the causes and solutions of the overheating of the hydraulic system of agricultural tracked transporters. I hope that when you encounter this situation, you can solve it by yourself and reply to the work of agricultural tracked transporters faster.
