      珠海叉車水溫過高的原因有哪些?

      2022-09-2337次
      叉車淺談引起內燃叉車水箱高溫的原因及解決辦法: 駕駛員都知道,有時分,尤其在夏天,內燃叉車的水箱會有很高溫的時分,有必要停下來,這樣就影響了叉車作業,嚴峻時還會損壞零部件,那有哪些原因引起叉車水箱高溫的呢?該怎么解決呢?叉車告訴你:
      forklift brief talk about the causes and solutions of high temperature in water tank of internal combustion forklift truck: drivers know that sometimes, especially in summer, the water tank of internal combustion forklift truck will have a high temperature, and it is necessary to stop, which will affect the operation of forklift truck and damage parts in severe times. what causes the high temperature in water tank of forklift truck? how to solve this problem?
      叉車水溫過高的原因
      reasons for excessive water temperature of forklift trucks
      水溫高有許多原因:控溫開關、泵、子扇、水管銹了、回水不好等要素都會引起這樣的結現象。發動機水溫的凹凸主要是和節溫器是否正常作業、水泵能否建立滿足的壓力、冷卻電扇能否達到標準轉速有關。那怎么來查看叉車水溫不正常呢?冷卻系統一般由冷卻電扇、散熱器、節溫器等元件構成。冷卻電扇往往由發動機直接帶動,而且電扇轉速與發動機轉速一致。冷卻水溫的控制主要依托節溫器。
      there are many reasons for the high water temperature: temperature control switches, pumps, fans, rusted water pipes, poor backwater and other factors can cause such a knot phenomenon. the concave and convex of engine water temperature is mainly related to whether the thermostat is working properly, whether the pump can establish the satisfied pressure, and whether the cooling fan can reach the standard speed. how to check the temperature of forklift truck is abnormal? cooling system is generally composed of cooling fans, radiators, thermostats and other components. cooling fans are often driven directly by the engine, and the speed of the fan is the same as that of the engine. the control of cooling water temperature mainly relies on thermostat.
      節溫器的原理
      principle of thermostat
      節溫器又稱調溫器,功用是根據冷卻水溫度的凹凸主動調理進入散熱器的水量,改動水的循環范圍,以調理冷卻系的散熱能力,確保發動機在適宜的溫度范圍內作業。節溫器有必要堅持杰出的技能狀況,否則會嚴峻影響發動機的正常作業。如節溫器主閥門敞開過遲,就會引起發動機過熱;主閥門敞開過早,則使發動機預熱時刻延長,使發動機溫度過低。此時可判斷節溫器的作業狀況是否杰出,當發動機開端冷車運轉時,水箱的上水室進水管處如還有冷卻水流出,則闡明節溫器的主閥門不能封閉;當發動機冷卻水溫度超越70攝氏度時,水箱的上水室進水管處無冷卻水流出,則闡明節溫器主閥門不能正常敞開,這時就需求進行修理。
      the function of thermostat is to actively adjust the amount of water entering the radiator according to the concave and convex temperature of cooling water and change the circulation range of water to adjust the cooling capacity of the cooling system and ensure that the engine works in the appropriate temperature range. it is necessary for thermostats to adhere to outstanding technical conditions, otherwise it will seriously affect the normal operation of the engine. if the main valve of the thermostat is opened too late, the engine will be overheated; if the main valve is opened too early, the preheating time of the engine will be prolonged and the temperature of the engine will be too low. at this time, it can be judged whether the operation of thermostat is outstanding or not. when the engine starts running, if there is cooling water flowing out from the water inlet pipe of the water tank, the main valve of the thermostat can not be closed. when the cooling water temperature of the engine exceeds 70 degrees celsius, there is no cooling water flowing out from the water inlet pipe of the water tank, the main valve of the thermostat can not be opened normally. it needs to be repaired.
      節溫器的查看可在車上進行,辦法如下:
      the thermostat can be checked in the car by the following methods:
      一、發動機起動后的查看:打開散熱器加水口蓋,若散熱器內冷卻水平靜,則標明節溫器作業正常,否則,則標明節溫器作業失常。
      1. view after engine starting: open the radiator nozzle cover, if the cooling level is still, it indicates that the thermostat works normally, otherwise, it indicates that the thermostat works abnormally.
      二、這是因為,在水溫低于70℃時,節溫器脹大筒處于縮短狀況,主閥門封閉;當水溫高于80℃時,脹大筒脹大,主閥門漸漸打開,散熱器內循環水開端流動。
      2. this is because when the water temperature is lower than 70 c, the expanding cylinder of the thermostat is in a shortened state and the main valve is closed; when the water temperature is higher than 80 c, the expanding cylinder expands, the main valve gradually opens, and the circulating water in the radiator begins to flow.
      三、當水溫表指示70℃以下時,散熱器進水管處若有水流動,水溫溫熱,則表時節溫器主閥門封閉不嚴,使冷卻水過早大循環。
      3. when the water thermometer indic
