  造成二手洒水车柴油机散热水箱漏水,除机械损伤外,多由腐蚀引起。
  Causes the second-hand sprinkler diesel engine radiator leakage, in addition to mechanical damage, mostly caused by corrosion.
  检查水箱的散热器密封性能,水箱的进出水口可以堵塞,水箱内充满0.05 ~ 0.1mpa的压缩空气,并将其溢出到水中,检查有无气泡流出。哪里有泡沫,哪里就有漏洞。应做烫印。
  Check the sealing performance of the radiator of the water tank. The water inlet and outlet of the water tank can be blocked. The water tank is filled with 0.05 ~ 0.1MPa compressed air, and it overflows into the water. Check whether there are bubbles flowing out. Where there is a bubble, there are loopholes. Hot stamping should be done.
  二手洒水车水箱散热器断漏部分,目前采用焊锡焊接方法进行修复。但对于铝材料的散热器,用锡进行热漂是非常困难的。原因是当铝表面暴露在空气中时,它会迅速形成一层薄薄的氧化膜,使得锡无法附着。如果采用下列焊接方法,操作将会成功。操作步骤为:
二手洒水车
  At present, the broken part of radiator of used sprinkler tank is repaired by soldering. But it is very difficult to use tin for heat bleaching of aluminum radiator. The reason is that when the aluminum surface is exposed to the air, it will quickly form a thin oxide film, so that tin can not adhere. If the following welding methods are used, the operation will be successful. The operation steps are as follows:
  (1)去污:先将裂缝周围的油土清理干净,然后用平铲沿裂缝挖沟。
  (1) Decontamination: first, clean up the oil and soil around the crack, and then use a flat shovel to dig a trench along the crack.
  (2)将松香粉与锏端混合(锏块锉可用作锉),洒于需焊槽上。
  (2) Mix rosin powder and mace end (MACE block file can be used as file) and sprinkle it on the groove to be welded.
  (3)加热铝散热器水室很大,烙铁的热量很容易传播,失去了在焊接过程中,焊接部分不能达到所需的温度,所以水箱应放置在炉子取暖,这样它就可以被维持在60 ~ 70°C。然后将熨斗加热到400°C左右,将tin或blanching粘在边缘,将pine powder和mace powder加热,融化混合。
  (3) The water chamber of the heating aluminum radiator is very large, and the heat of the soldering iron is easy to spread. In the process of welding, the welding part cannot reach the required temperature, so the water tank should be placed in the furnace for heating, so that it can be maintained at 60 ~ 70 ° C. Then heat the iron to about 400 ° C, stick tin or blanching on the edge, heat pine powder and mace powder, melt and mix.
  (4) hang tin的烙铁在焊接部位不断摩擦,松香中的mace末端不断去除铝表面的氧化层,使铝没有机会再生。同时,锡会趁机附着在铝的表面上。这一步是成功和失败的区别。耐心地反复摩擦,直到你挂一层锡。挂起锡后,当松香没有凝固时,用抹布迅速擦去松香和锏的末端,在烫印上留下一层锡。如果某些地方没有挂锡,应按照上述方法继续操作。
  (4) The soldering iron of Hang tin is constantly rubbing at the welding position, and the oxide layer on the aluminum surface is constantly removed at the end of mace in rosin, so that the aluminum has no chance to regenerate. At the same time, tin will adhere to the surface of aluminum. This step is the difference between success and failure. Rub patiently until you hang a layer of tin. After suspending the tin, when the rosin is not solidified, wipe off the end of the rosin and mace quickly with a rag and leave a layer of tin on the hot stamping. If there is no tin hanging in some places, continue to operate as above.
  (5)所有焊缝均挂锡后,按常规方法进行焊接,直至裂纹完全填满。
  (5) After all welds are hung with tin, the welding shall be carried out according to the conventional method until the cracks are completely filled.
  实践证明,当水箱裂缝在0.3mm左右时,可用水箱堵剂进行修补。该方法操作简单,特别适合在施工现场进行维修。而这种堵剂,在一般的化学试剂商店都有供应。堵剂的操作方法可按以下步骤进行:
  The practice shows that when the water tank crack is about 0.3mm, the water tank plugging agent can be used for repairing. This method is easy to operate and is especially suitable for maintenance on the construction site. And this kind of plugging agent is available in general chemical agent stores. The operation method of plugging agent can be carried out as follows:
  (1)清洗水箱的散热器。水箱冷却清洗是堵塞过程的重要组成部分,它直接影响着堵塞效果。
  (1) Clean radiator of water tank. Cooling and cleaning of water tank is an important part of the plugging process, which directly affects the plugging effect.
  清洗方法是在热循环状态下使用2%的纯碱水,对散热器水箱内壁、裂缝表面和水循环通道进行清洗。加入纯碱水后,柴油机应在80℃左右的温度下运行5 ~ 10min,并在高温时放出碱水。然后灌满清水,启动柴油发动机,当温度上升到80°C时,将其全部释放。如果水是脏的,再用清水冲洗。
  The cleaning method is to clean the inner wall, crack surface and water circulation channel of radiator water tank by using 2% soda water in the thermal cycle state. After adding soda water, the diesel engine shall be operated for 5-10min at a temperature of about 80 ℃, and alkali water shall be discharged at a high temperature. Then fill with clean water, start the diesel engine, when the temperature rises to 80 ° C, release it all. If the water is dirty, rinse with clean water.
  (2)拆卸恒温器。
  (2) Remove the thermostat.
  (3)在冷却系统中加入堵剂。堵剂与水的比例为1:20。
  (3) Add plugging agent into the cooling system. The ratio of plugging agent to water is 1:20.
  (4)启动柴油机,将水温调至80 ~ 85℃,保持30分钟左右。
  (4) Start the diesel engine, adjust the water temperature to 80 ~ 85 ℃, and keep it for about 30 minutes.
  (5)待散热器水箱完全冷却后,重新启动柴油机,加热至80 ~ 85℃,保持10 ~ 15min。这一步更好在第二天完成,之后就可以投入使用了。
  (5) After the radiator water tank is completely cooled, restart the diesel engine, heat it to 80 ~ 85 ℃, and keep it for 10 ~ 15min. It's better to finish this step the next day and then put it into use.
  (6)堵剂应在散热器水箱内存放3 ~ 5天,不要轻易拖延。存放时间越长越好。
  (6) The plugging agent shall be stored in the radiator water tank for 3-5 days, and shall not be delayed easily. The longer the storage time, the better.
