Effect Of Low Temperature On Road Roller

Summary: Winter has arrived, have you taken well-prevented for the road roller cold-proof ? Today, I will share with you some of the adverse effects of roller compactors at low temperatures. These effects are mainly reflected in the impact on the roller, the engine, the lubricating oil, etc. details as follows:
Winter has arrived, have you taken well-prevented for the  road roller cold-proof ? Today, I will share with you some of the adverse effects of roller compactors at low temperatures. These effects are mainly reflected in the impact on the roller, the engine, the lubricating oil, etc. details as follows:

The low temperature makes the engine difficult to start, mainly due to the increased viscosity of the lubricating oil, the reduced 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 properties decrease, thereby deteriorating the engine lubrication conditions and increasing the rotational resistance of the crankshaft.

When the battery is at a low temperature, the viscosity of the electrolyte also increases, the magnetic permeability decreases, and the increase in internal resistance causes a significant drop in battery capacity and terminal voltage, and even discharge. The voltage drop prevents the initiator from achieving the required output power and it is difficult to meet the startup speed requirements.

The low temperature blast, the engine crankshaft speed is not high, the intake pipe temperature and gas flow rate are low, and the atomization quality of the fuel is poor, which further increases the difficulty of starting the engine.

At low temperatures, various oils have high viscosity and poor flow, which makes handling of the rolls difficult and exacerbates machine wear.

The viscosity of the lubricating oil is large, the power loss of the agitating oil increases during the operation of the mechanism, the engine power is reduced, and the efficiency of the transmission system is lowered, thereby reducing the driving ability and the excitation mechanism of the roller traveling.

The poor fluidity of the lubricating oil increases the difficulty of lubricating certain components and reduces the lubrication, which in turn increases the wear of the engine and transmission components.

The viscosity of the working oil is large, the resistance of the pipeline is increased, the hydraulic steering gear is difficult to operate, the performance of the hydraulic brake is lowered, the driving difficulty is increased, and the safety driving is adversely affected.

Cooling of the battery electrolyte will cause it to stop working; freezing of the water-cooled engine cooling water will freeze the radiator and cylinder block.


It is now winter. The roller in operation should be drained in time or replaced with antifreeze. The engine should be replaced with winter oil to avoid unnecessary losses due to sudden changes in the weather. Do not rush to open the vibration during the winter use. After static pressure for 20 minutes, the vibration will be turned on again until the vibration is stable.
