  1. 当机器停机时,水排得太早或没有放冷却水。机器停机前,应以空速运转。如果冷却水排出过早,当温度较高时,机体会在冷空气的冲击下突然收缩开裂。排水时,应将体内残留的水分全部排出,避免冻结和膨胀,使机体爆裂。

  1. When the machine is stopped, the water is discharged too early or the cooling water is not discharged. Before the machine is shut down, it should run at idle speed. If the cooling water is discharged too early, when the temperature is high, the machine will contract and crack suddenly under the impact of cold air. During drainage, the residual water in the body shall be discharged completely to avoid freezing and expansion, so as to burst the body.

  2. 用明火点燃,不要拆下空气滤清器,将棉纱浸在柴油中点燃

  2. Ignite with open fire, do not remove the air filter, and soak the cotton yarn in diesel oil to ignite

  点火器被放置在进气管内以开始燃烧。这样在起动过程中,外界的粉尘空气就不会过滤而直接进入气缸,造成活塞、气缸等部件的异常磨损,还会造成柴油机工作粗糙,损坏机器。

  The igniter is placed in the intake pipe to start combustion. In this way, in the process of starting, the outside dust air will not be filtered directly into the cylinder, causing abnormal wear of the piston, cylinder and other components, and also causing rough operation of the diesel engine, damaging the machine.

  3、用明火烘烤油底壳,以免使油底壳变质,甚至烧焦、润滑

  3. Bake the oil pan with open fire to avoid deterioration, even scorch and lubrication of the oil pan

  减少或完全失去,从而增加机器磨损。冬季应选用低凝固点油。启动时可采用外置水浴提高油温。

  Reduce or completely lose, thus increasing machine wear. Low freezing point oil should be used in winter. External water bath can be used to increase oil temperature during startup.

  4、启动方法不合适,有些用户可以快速启动柴油机,经常不用水。启动(先启动,然后加入冷却水)的异常启动方法。这将对机器造成严重的损害,应该被禁止。

  4. The starting method is not suitable. Some users can start the diesel engine quickly without water. Abnormal start-up method of starting (start first, then add cooling water). This will cause serious damage to the machine and should be banned.

  5、低温负荷运行时,柴油机启动起火后,有些司机迫不及待地立即投入负荷运行。不久就着火的柴油机,由于机体温度低,油粘度大,油不易填满运动副的摩擦面,会导致机器严重磨损。此外,柱塞弹簧、阀弹簧和喷射器弹簧也容易因“冷脆”而断裂。因此,柴油机在冬季点火后,应在中低转速下怠速几分钟,待冷却水温度达到60℃后再投入负荷运行。

  5. During low-temperature load operation, some drivers can't wait to put into load operation immediately after the diesel engine starts fire. Because of the low temperature of the engine block and the high viscosity of the oil, it is not easy for the oil to fill the friction surface of the moving pair, which will cause serious wear of the engine. In addition, plunger spring, valve spring and ejector spring are easy to break due to "cold brittleness". Therefore, after ignition in winter, the diesel engine should idle for several minutes at low and medium speed, and then put into load operation after the temperature of cooling water reaches 60 ℃.

  6、不注意机体保温,冬季温度低,容易使柴油机工作时过度冷却。因此,低温条件下柴油机的保温是柴油机良好使用的关键。在北方,冬季使用的柴油机应配备保温罩和保温帘等冷态设备。

  6. Do not pay attention to the heat preservation of the engine body, and the temperature is low in winter, which is easy to cause excessive cooling of the diesel engine during operation. Therefore, the heat preservation of diesel engine at low temperature is the key to the good use of diesel engine. In the north, diesel engines used in winter shall be equipped with cold equipment such as heat shield and heat curtain.

  7. 鉴于各地天气逐渐降温,提醒用户全面检查开关、电源、阀门,确保绝对安全;

  7. In view of the gradual cooling of the weather around, remind the user to check the switch, power supply and valve comprehensively to ensure absolute safety;

  8. 检查温度和冷却剂与防冻剂的比例是否符合当地的温度;

  8. Check whether the minimum temperature and the ratio of coolant and antifreeze meet the local minimum temperature;

  9. 检查燃油情况,如将原来的0#柴油更换为-10#或-20#柴油(根据当地气候选择);

  9. Check the fuel condition, such as replacing the original 0 × diesel with - 10 × or - 20 × diesel (selected according to the local climate);

  10. 建议在重要机房安装温度计,保证机组运行时进排气顺畅。北方较冷地区对机房进行绝缘,必要时进行整改。
