叉車節溫器的檢查要檢查哪些?

  1. 發動機起動后檢查:打開散熱器的加油口蓋。如果散熱器中的冷卻水是平靜的,這意味著恒溫器工作正常;否則,這意味著恒溫器不能正常工作。

  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. 這是因為當水溫低于70時,恒溫器膨脹缸處于締約狀態,主閥關閉;當水溫高于80時,膨脹缸膨脹,主閥逐漸打開,散熱器中的循環水開始流動。
  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、當溫度表指示溫度低于70時,散熱器進入管道內如有水流,溫度較暖,則表溫調溫器主閥關閉不嚴格,使冷卻水過早循環。
  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、水溫升高后檢查:發動機運行初期水溫在1000元以上。當溫度表顯示80時,溫升速度減慢,說明溫控器工作正常。反之,如果水溫一直在迅速上升,當內部壓力達到一定水平時,沸水突然溢出,說明主閥卡住了,突然打開。
  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. 當水溫表指示70-80時,打開散熱器蓋和散熱器排水開關,處理水溫。如果溫度很高,恒溫器就會正常工作。如果散熱器入口水溫較低,沒有水流出或散熱器上腔入口管道流出的水很少,則恒溫器的主閥無法打開。
  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.
  水泵是冷卻水在冷卻系統中不斷循環的動力,影響水泵的因素有葉輪和皮帶,葉輪松動冷卻水不能循環,造成水泵損壞。皮帶過大,導致水溫過高,過小會對泵軸承、發電機軸承造成損壞。
  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.
  風機風量試驗:散熱器前可放置一張紙。發動機運轉時,如果能吹紙,風量就足夠了。這與前引擎吸進空氣的汽車風扇不同。葉片不能向后安裝,風機釋放蓋應完整有效。
  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.
  散熱器,叉車底盤較低,散熱器位于車輛后部。散熱器表面容易積灰,如不及時清理,將嚴重影響散熱效果。冷卻水中嚴禁使用“硬水”,防止散熱器產生水垢,導致冷卻水添加不足。
  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.
