叉车节温器的检查要检查哪些?

来源:/ 日期:2019-09-25 发布人:admin

  1. 发动机起动后检查:打开散热器的加油口盖。如果散热器中的冷却水是平静的,这意味着恒温器工作正常;否则,这意味着恒温器不能正常工作。

  1. Check after engine start: Open the refueling cover of radiator. If the cooling water in the radiator is calm, it means that the thermostat works properly; otherwise, it means that the thermostat does not work properly.
  2. 这是因为当水温低于70时,恒温器膨胀缸处于缔约状态,主阀关闭;当水温高于80时,膨胀缸膨胀,主阀逐渐打开,散热器中的循环水开始流动。
  2. This is because when the water temperature is below 70, the expansion cylinder of the thermostat is in the Contracting State and the main valve closes; when the water temperature is above 80, the expansion cylinder expands, the main valve opens gradually, and the circulating water in the radiator begins to flow.
  三•●、当温度表指示温度低于70时,散热器进入管道内如有水流,温度较暖,则表温调温器主阀关闭不严格,使冷却水过早循环。
  3. When the temperature indicated by the thermometer is below 70, if the radiator enters the pipeline with water flow and the temperature is warmer, the main valve of the thermostat is not closed strictly, which makes the cooling water circulate prematurely.
  四•●、水温升高后检查:发动机运行初期水温在1000元以上。当温度表显示80时,温升速度减慢,说明温控器工作正常。反之,如果水温一直在迅速上升,当内部压力达到一定水平时,沸水突然溢出,说明主阀卡住了,突然打开。
  4. Check after the water temperature rises: the initial water temperature of the engine is over 1000 yuan. When the thermometer shows 80, the speed of temperature rise slows down, indicating that the thermostat works normally. Conversely, if the water temperature has been rising rapidly, when the internal pressure reaches a certain level, the boiling water suddenly overflows, indicating that the main valve is stuck and suddenly opened.

  5. 当水温表指示70-80时,打开散热器盖和散热器排水开关,处理水温。如果温度很高,恒温器就会正常工作。如果散热器入口水温较低,没有水流出或散热器上腔入口管道流出的水很少,则恒温器的主阀无法打开。
  5. When the thermometer indicates 70-80, open the radiator cover and the radiator drain switch to handle the water temperature. If the temperature is very high, the thermostat will work normally. If the inlet water temperature of the radiator is low, there is no water flow out or very little water flow out of the inlet pipe of the upper chamber of the radiator, the main valve of the thermostat can not be opened.
  水泵是冷却水在冷却系统中不断循环的动力,影响水泵的因素有叶轮和皮带,叶轮松动冷却水不能循环,造成水泵损坏。皮带过大,导致水温过高,过小会对泵轴承•●、发电机轴承造成损坏。
  Pump is the power of continuous circulation of cooling water in the cooling system. The factors affecting the pump are impeller and belt. The loosened impeller can not circulate cooling water, causing damage to the pump. The belt is too large, resulting in high water temperature, too small will cause damage to pump bearings, generator bearings.
  风机风量试验:散热器前可放置一张纸。发动机运转时,如果能吹纸,风量就足够了。这与前引擎吸进空气的汽车风扇不同。叶片不能向后安装,风机释放盖应完整有效。
  Fan air volume test: a sheet of paper can be placed in front of the radiator. When the engine runs, if you can blow paper, the air volume is enough. This is different from a car fan whose front engine sucks in air. Blades can not be installed backwards, fan release cover should be complete and effective.
  散热器,叉车底盘较低,散热器位于车辆后部。散热器表面容易积灰,如不及时清理,将严重影响散热效果。冷却水中严禁使用“硬水”,防止散热器产生水垢,导致冷却水添加不足。
  Radiator, forklift chassis is low, radiator is located in the rear of the vehicle. The surface of radiator is easy to accumulate dust. If it is not cleaned up in time, it will seriously affect the heat dissipation effect. It is strictly forbidden to use "hard water" in cooling water to prevent scaling of radiator, which leads to insufficient cooling water.
