PTJ-120 Sprayer Machine hydraulic system oil temperature is too high, it will reduce the viscosity of the oil, increase the amount of leakage, damage the oil film of the lubricating parts, increase the wear of the parts. Damage Therefore, it is very important to control the proper oil temperature. When the oil temperature is too high, it must be stopped for inspection. In general, the following aspects can be considered:
Check whether the oil level in the fuel tank is too low. Experience has shown that excessive oil temperature is often caused by a lack of fuel in the fuel tank, so oil should be replenished in a timely manner.
Check the hydraulic oil filter element and circuit for blockage. Is the radiator normal? If there is a lot of dust attached to the radiator, it may cause poor heat dissipation. The temperature of the PTJ-120 Sprayer Machine will increase when the oil temperature increases. The radiator should be cleaned in time. The hydraulic oil quality is qualified, the refueling quality is unqualified, and the system oil temperature is too high.
Paver screw conveyor not working
Sometimes, due to the failure of the PTJ-120 Sprayer Machine fueling system, the pressure of the charge pump system is low due to the left and right spreaders not working: the charge pump inlet passage is not smooth; the charge pump relief valve pressure is low; the charge pump itself is faulty; the hydraulic motor Severe leaks In general, it is important to check the make-up pump and its relief valve.
