Road roller, also called soil compactor, is a kind of road repairing equipment. However, in daily operations, different environmental weather will bring different effects, especially in low temperature and cold weather, may reduce the driving ability of the roller. In this article, the editor of Xianji.com takes everyone to understand.
The low temperature makes it difficult to start the engine. The main reasons are the increased viscosity of the lubricating oil, the decrease in the working capacity of the battery and the poor fuel atomization.
As the temperature decreases, the viscosity of the engine oil increases, and the flow performance deteriorates, thereby deteriorating the lubrication conditions of the engine and increasing the rotational resistance of the crankshaft.
When the battery is at a low temperature, the viscosity of the electrolyte also increases, the penetration capacity decreases, and the increase in internal resistance significantly reduces the battery capacity and terminal voltage, and even cannot discharge. The voltage drop prevents the starter from getting the required output power, making it difficult to achieve the starting speed requirement.
Due to the low temperature, the crankshaft speed of the engine starting is not high, the temperature of the intake pipe and the gas flow rate are low, and the atomization quality of the fuel is poor, which further increases the difficulty of starting the engine.
Under low temperature conditions, various oils have high viscosity and poor fluidity, which brings difficulties to the operation of the roller and aggravates the wear of the machine parts.
The viscosity of the lubricating oil is large, the loss of stirring power during the operation of the mechanism is increased, the engine power is reduced, and the efficiency of the transmission system is low, thereby reducing the driving ability of the roller walking and vibration excitation mechanism.
The poor fluidity of lubricating oil increases the difficulty of lubricating certain components and reduces the lubricating effect, thereby aggravating the wear of the engine and transmission components.
The high viscosity of the working oil also increases the resistance of the pipeline, making it difficult to control the hydraulic steering, the efficiency of the hydraulic drive brake is deteriorated, and the difficulty of driving is increased, which has an adverse effect on safe driving.
In the cold season, there are also widespread freezing hazards, such as: the electrolyte of the battery will freeze and it will stop working; the freezing of the cooling water of the water-cooled engine will freeze and crack the radiator and the cylinder block.
