1. Protect the engine
Reduce start-up wear: At low temperatures, the viscosity of the lubricating oil increases, the fluidity deteriorates, and the lubrication effect decreases. Preheating can make the lubricating oil reach a suitable temperature and reduce the wear of the engine when starting.
Improve start-up efficiency: In a low temperature environment, the engine is difficult to start, and preheating can make the engine easier to start and reduce the start-up time.
2. Protect the hydraulic system
Reduce the viscosity of the hydraulic oil: The viscosity of the hydraulic oil is higher at low temperatures. Preheating can increase the temperature of the hydraulic oil, reduce the viscosity, and reduce the wear of the hydraulic system components.
Improve the efficiency of the hydraulic system: After preheating, the hydraulic oil has better fluidity, the hydraulic system has higher working efficiency, and reduces hydraulic system failures.
3. Improve the overall performance of the equipment
Reduce component wear: Preheating can make the various components of the equipment operate at normal temperature, reducing component wear caused by low temperature.
Improve work efficiency: After preheating, the equipment can enter the working state faster and reduce the power drop caused by insufficient temperature.
4. Ensure safe operation
Avoid operational difficulties: The viscosity of hydraulic oil is high at low temperatures, and the hydraulic system is difficult to operate. Preheating can avoid this problem and ensure operational flexibility.
Reduce braking risks: Preheating can ensure the effectiveness of hydraulic drive brakes and avoid the degradation of braking performance due to low temperatures.
5. Prevent equipment damage
Avoid freezing of the cooling system: In cold areas, the water in the cooling system may freeze. Preheating can prevent the cooling system from freezing and avoid equipment damage.
Reduce freezing hazards: Preheating can prevent the freezing of battery electrolytes and avoid equipment failures due to low temperatures.
6. Extend equipment service life
Reduce the impact of low-temperature startup on equipment: When starting at low temperatures, the engine and hydraulic system are under greater pressure. Preheating can reduce this impact and extend the service life of the equipment.
Keep the equipment in good condition: Preheating can enable the equipment to operate within the optimal temperature range and reduce equipment failures caused by temperature changes.
7. Improve construction quality
Ensure compaction effect: After preheating, the equipment can better perform the compaction function and improve construction quality.
Specific operation suggestions for preheating
Idle operation: When cold starting, the engine should be allowed to idle for 3 to 5 minutes, and the operation should be started after the hydraulic oil temperature rises to above 30°C.
No-load operation: After preheating, let the equipment run without load for 5 to 15 minutes to ensure that all components are fully preheated.
