【文章內(nèi)容簡介】 he diesel engine, changing the oil properties, disrupt the normal lubrication, affect the normal operation of diesel engines. Visible, oil cooler repair is diesel engine lubrication system maintenance is the most important part of. The author thinks, oil cooler in addition to cleaning, assembly should pay attention to the following matters:ａ、 將冷卻器芯裝入冷卻器體，然后將冷卻器體放在平臺上，使其后端朝上。 A, the cooler core into the cooler body, and then the cooler body is placed on the platform, so that the rear end face. ?。狻⒆⒁庋b配記號。將冷卻器芯的裝配記號與冷卻器殼體上的裝配記號對準(zhǔn)，如圖１所示。另外，有些冷卻器具有兩個標(biāo)示記號，在管束端板有一個“V ”記號，在孔緣內(nèi)徑上切有缺口“ ”，如圖２所示。裝配時用缺口“ ”記號將冷卻器芯與殼體記號對準(zhǔn)。 B, note assembly mark. The cooler core assembly mark and the cooler housing assembly mark alignment, as shown in figure 1. In addition, some cooler has two mark mark, in tube end plate having a V mark, in diameter hole edge cutting notch , as shown in figure 2. When the assembly notch mark will be cooler core and shell alignment mark.圖１：管筒式機(jī)油冷卻器芯的裝配記號 圖２：冷卻器芯的標(biāo)示記號Figure 1: tube type oil cooler core assembly mark figure 2: cooler core mark mark ?。恪?一定要用植物油潤滑“O ”形密封圈。新型“O ”形密封圈有兩條紅帶，其材料接觸機(jī)油后會迅速脹大，難以順利裝入。然后將其推入冷卻器與冷卻器體之間，注意勿使“O ”形密封圈卷嵌在芯與體之間。該密封圈為一次性用品。C, must use vegetable oil lubricant O shaped sealing ring. Model O shaped seal ring has two red belt, the material of the contact after the oil could quickly swell, difficult to successfully mount. Then push into the cooler and the cooler body, pay attention not to make O shaped sealing ring is embedded in the core and the body volume. The sealing ring is a disposable items. ?。?、 裝上檔圈，應(yīng)使零件號朝上。D, put the ring, should make the part number is up. ?。?、將支蓋、新墊片支架和新墊片裝到冷卻器體上，將螺釘擰緊至41～ 47 N．m ，然后裝好所有螺釘。E, the supporting cover, new gasket bracket and a new gasket fitted into the cooler body, the screws are tightened to41～ 47 , and then install all bolts.?。ǎ矗┎裼蜋C(jī)冷卻通道(4) diesel engine cooling channel 在柴油機(jī)大修時，有的班組忽視對冷卻通道的徹底清洗，具體表現(xiàn)在，散熱器和缸蓋拆下后扔到一旁，到總裝時再將其表面擦拭干凈。這是造成冷卻系產(chǎn)生故障較多的原因之一。如裝6BT 系列柴油機(jī)，常常發(fā)生散熱器上水室頂部和氣缸蓋出水管一端的兩根除氣管都不通。這樣，在加注冷卻液時，積聚在氣缸體內(nèi)套的空氣和氣、水混合物就無法排出，冷卻液也無法充滿水套。柴油機(jī)在工作過程中，當(dāng)積滯的氣體達(dá)到一定程度時，還會造成水泵流量下降，結(jié)果是在氣缸體水套內(nèi)部產(chǎn)生局部高溫，最終造成氣缸體局部熱應(yīng)力猛增而使缸體局部破裂。因此，在柴油機(jī)大修或其產(chǎn)生高溫故障時，應(yīng)認(rèn)真清洗冷卻系，切不可馬虎了事。In the diesel engine overhaul, some teams neglecting cooling passages in the performance of specific, thorough cleaning, radiator and cylinder head removed aside, to the assembly when the surface is wiped clean. This is caused by the cooling system has more faults reasons. As of6BT series diesel engine, radiator water chamber top and often occurred in cylinder head outlet end of the two air out. Thus, in filling in coolant, accumulate in the cylinder sleeve, air and water mixture is unable to discharge, cooling liquid can filled with water jacket. Diesel engine in the course of work, when the accumulated gas to a certain extent, can also cause water pump flow decreased, the result is in a cylinder water jacket internally generated local high temperature, resulting in local thermal stress of cylinder body and the cylinder explosion partial rupture. Therefore, the diesel engine or the high temperature failure, should be carefully cleaning cooling system,
