The effect of low temperature on the work of the roller:
Low temperature makes it difficult to start the engine, mainly due to the increase in the viscosity of the lubricating oil, the decrease in the working capacity of the battery and the poor atomization of the fuel. The viscosity of the oil increases as the temperature decreases, and the flow performance deteriorates, thereby making the engine lubricating conditions worse, and the rotational resistance of the crankshaft increases. When the battery is at a low temperature, the viscosity of the electrolyte also increases, the permeability decreases, and the internal resistance increases, which significantly reduces the battery capacity and terminal voltage, and even cannot be discharged. The voltage reduction makes the starter unable to obtain the required output power, and it is difficult to meet the requirements of the starting speed. Due to the low temperature, the crankshaft speed of the engine 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 road roller and aggravates the wear of the parts. The viscosity of the lubricating oil is large, the oil churning power loss increases when the mechanism is running, the engine power is reduced, and the efficiency of the transmission system is low, thereby reducing the driving ability of the road roller and the vibration excitation mechanism. The poor fluidity of the lubricating oil makes it difficult to lubricate some parts and reduces the lubricating effect, thereby aggravating the wear of the engine and transmission parts. The viscosity of the working oil is high, which also increases the resistance of the pipeline, making the hydraulic steering difficult to control, and the performance of the hydraulic drive brakes deteriorates, which increases the difficulty of driving and has an adverse effect on safe driving. There are also common freezing hazards during construction in cold seasons. For example, the freezing of the electrolyte of the battery will cause it to stop working; the freezing of the cooling water of the water-cooled engine will freeze the radiator and the cylinder block.
