oil temp and pressure gauge

• 2022-02-23

The oil temperature gauge and oil pressure gauge of loader are the same as the oil temperature gauge and oil pressure gauge of automobile: the measurement unit of oil temperature gauge is expressed in degrees, and the scale is generally between 50 ~ 150 degrees; The oil pressure gauge is expressed in kilogram or bar (MPA) of gravity unit, and the scale is generally between 0 and 1.0 degrees.

Oil temperature and oil pressure are indicators that reflect the condition of the engine. From the oil temperature and pressure, we can know the condition of the oil, the working condition of the engine and so on. It can be seen that the oil temperature gauge and oil pressure gauge are very helpful to judge the vehicle condition.Engine oil, i.e. engine lubricating oil, is known as the "blood" of automobile, which can lubricate, clean, cool, seal, reduce wear, prevent rust, prevent corrosion and so on.

Oil temperature and oil pressure are indicators that reflect the condition of the engine. From the oil temperature and pressure, we can know the condition of the oil, the working condition of the engine and so on. It can be seen that the oil temperature gauge and oil pressure gauge are very helpful to judge the vehicle condition.The oil temperature gauge reflects the temperature of the lubricating oil when the engine is running.Oil pressure gauge, commonly known as oil gauge, indicates the lubricating oil pressure of the main oil passage of the lubricating system when the engine is running.

The oil temperature reflects the lubricating effect of the oil on the engine. When the oil temperature is too high, it will accelerate the aging of the engine and reduce the service life of the engine. If the oil temperature is too high, the viscosity of the oil will decrease, the oil film will be difficult to establish, and the oil pressure will decrease, resulting in accelerated wear of the moving pair. The engine oil often works at high temperature, which will accelerate the aging of the engine oil and reduce the service life of the engine oil itself. If the oil temperature is too high, it will also cause the rubber sealing ring to age and fail at high temperature, resulting in oil leakage.

When the oil pressure is too low, the following engine faults will be caused:
1) The oil viscosity is too low;
2) The filter screen of the oil filter collector or the filter element of the oil filter is blocked;
3) The spring force of the pressure limiting valve and the oil return valve is weakened or broken, or the sealing of the valve joint surface is not tight, resulting in oil leakage and pressure relief;
4) The clearance of main bearing or connecting rod bearing is too large;
5) The oil pump is not working properly.
