强夯机厂家分享冬季保养必备技巧!

随着冬季来临,低温环境对强夯机的发动机和液压系统带来了考验。低温直接导致液压油及机油粘度增加,从而导致流动性变差、阻力增大、工作效率低等现象。
With the coming of winter, the low temperature environment brings test to the engine and hydraulic system of dynamic compaction machine. Low temperature directly leads to the increase of viscosity of hydraulic oil and engine oil, resulting in poor liquidity, increased resistance and low work efficiency.
发动机低温冷启动各零部件未能得到充分润滑,带负载工作损伤发动机部件,从而影响发动机寿命。
As a result, the engine parts are not fully lubricated under cold load, which affects the working life of the engine.
对于液压系统,液压油温低于20℃,急速运转甚至会损坏泵、马达、阀等液压元件。为提升强夯机工作效率及使用寿命,强夯机进行冷启动预热是非常必要的。
For the hydraulic system, the hydraulic oil temperature is lower than 20 ℃, and the rapid operation may even damage the pump, motor, valve and other hydraulic components. In order to improve the working efficiency and service life of dynamic compaction machine, it is very necessary to preheat the dynamic compaction machine during cold start.

强夯机冬季施工前必须按步骤预热,待液压油温度达到20℃以上,发动机冷却水温达到60℃以上才能开始施工。接下来为您呈上一份强夯机预热指导手册,请各位收好查看~
The dynamic rammer must be preheated step by step before winter construction. The construction can be started only when the hydraulic oil temperature reaches above 20 ℃ and the engine cooling water temperature reaches above 60 ℃. Next, I'd like to present a warm-up instruction manual of dynamic compaction machine for you~
1、用车前检查:检查发动机冷却液液位、机油液位及液压油液位,保证液量充足,检查油水分离器积水情况并及时放水。
1. Inspection before use: check the engine coolant level, oil level and hydraulic oil level to ensure sufficient liquid volume, check the water accumulation in the oil-water separator and drain the water in time.
2、预热前准备: 夯锤从脱钩器上脱下(整机无负载),插入钥匙上电不启动发动机。检查驾驶室内显示屏信息无故障报警,确保车辆周边无行人和障碍物,并鸣笛示意。
2. Preparation before preheating: the hammer is removed from the uncoupling device (the whole machine has no load), the key is inserted, and the engine is not started when it is powered on. Check the display screen information in the driver's cab to ensure that there are no pedestrians and obstacles around the vehicle, and whistle to indicate.
3、扭动点火开关启动发动机,发动机无负荷怠速(800转左右)运转约3分钟(不进行操作动作),对发动机进行预热,让发动机各零部件充分润滑。
3. Turn the ignition switch to start the engine. The engine runs at idle speed (about 800 RPM) for about 3 minutes without any operation. Warm up the engine to make all parts of the engine fully lubricated.
4、踩油门踏板(或者调节手油门),逐步提升发动机转速至1500转左右,无负荷状态(不进行操作动作)运行约5分钟。
4. Step on the accelerator pedal (or adjust the hand accelerator), gradually increase the engine speed to about 1500 rpm, and run for about 5 minutes under no-load condition (no operation).
5、保持发动机转速1500转左右,向上打开先导开关,操作主卷扬手柄,进行空钩提升、下放动作,使液压油进行快速预热。
5. Keep the engine speed about 1500 rpm, turn on the pilot switch upward, operate the main winch handle, lift and lower the empty hook to preheat the hydraulic oil quickly.
6、观察显示屏信息,液压油温达到20℃,发动机水温达到60℃即可停止预热,进行正常施工。
6. Observe the information on the display screen, when the hydraulic oil temperature reaches 20 ℃ and the engine water temperature reaches 60 ℃, the preheating can be stopped and normal construction can be carried out.
对于不同环境温度及使用条件,需使用特定型号的液压油及发动机燃油。
For different ambient temperatures and service conditions, specific types of hydraulic oil and engine fuel should be used.
