Howo nx dump truck hydraulic oil replacement cycle
Howo nx tipper hydraulic oil replacement cycle needs to be comprehensively judged based on frequency of use, environment and workload, and common recommendations are as follows:
1. First replacement: It is recommended to replace the hydraulic oil of the new howo nx tipper 3 months or half a year after the first use.
2. Subsequent replacement
By time: Under normal use, it is recommended to replace once a year; if the frequency of use is low, the longest shall not exceed 1.5-2 years.
By working time: The life of hydraulic oil is usually 4000-6000 hours (about 2 years), and the replacement cycle can be adjusted according to the actual working time.
By oil quality: If the hydraulic oil turns black, impurities or white foam appear, it needs to be replaced immediately.
3. Special environment: If the working environment of dump trucks sinotruck is dusty, high temperature or high humidity, it is recommended to shorten the replacement cycle to 6-8 months.
4. The difference between synthetic oil and ordinary oil: Ordinary hydraulic oil is recommended to be replaced once a year, while synthetic hydraulic oil can be extended to 3 years.
Five major hidden dangers of not changing hydraulic oil overtime
1. Decreased system efficiency
The viscosity of the hydraulic oil is abnormal after oxidation, which leads to increased pump load or insufficient lubrication, reduced hydraulic system response speed and stability, and increased energy consumption.
2. Impurity accumulation causes failures
If the hydraulic oil of the howo dump truck has not been replaced for a long time, it will accumulate tiny particles such as metal debris and dust, block the filter element and valve core, cause poor oil absorption, component wear and even jam.
3. Aggravate corrosion and wear of components
The acidic substances and oxides in the deteriorated oil will corrode metal parts, accelerate the wear of key components such as cylinders and valve cores, and shorten the life of the howo nx tipper truck.
4. Decreased sealing performance
Aging hydraulic oil of the howo nx dump truck will cause the seals to harden or swell, causing system leakage and increasing maintenance costs.
5. Abnormal oil temperature rise
Dyed or abnormally viscous hydraulic oil will increase system friction, causing the oil temperature of the howo nx tipper truck to remain high, further accelerating oil oxidation and equipment aging.
Maintenance recommendations
1. Regular inspection
Determine whether it needs to be replaced by visually inspecting the color of the howo nx tipper, feeling impurities, or professional oil quality inspection.
2. Adjust the cycle as needed
Shorten the replacement interval under high-load operation or harsh environment, and use synthetic oil to extend the cycle.
3. Clean the system in time
When changing the oil, the sludge must be thoroughly cleaned, and a high-precision oil filter must be used to extend the oil life.
If you need more detailed operating instructions or oil quality inspection standards, please refer to the equipment manual or consult professional maintenance personnel.
In summary, regular replacement of hydraulic oil and strengthening the maintenance of the hydraulic system are key measures to ensure the normal operation and extend the service life of the howo nx dumper truck.
