焦化發(fā)電機(jī)組發(fā)動(dòng)機(jī)機(jī)體是由灰口鑄鐵原材料筑成的殼體，工作上承擔(dān)各種各樣里外負(fù)載，一般情形下機(jī)體毀壞有下列幾類方式：

The engine body of coking generator set is a shell made of gray cast iron raw materials, which bears various internal and external loads. Generally, the body is damaged in the following ways:

1、凍破。這也是冬天發(fā)動(dòng)機(jī)非常容易產(chǎn)生的毀壞。機(jī)體發(fā)生的裂紋僅有在沒(méi)有承受力的位置才可以用噴焊法修復(fù)。更先在裂紋兩邊打止孔裂，隨后沿裂紋栽多個(gè)顆釘子，再垂直平分裂紋方位補(bǔ)板若干塊，用低碳鋼焊條沿裂紋和補(bǔ)板焊牢。留意邊焊邊用鐵錘輕拍焊接，所有焊過(guò)后再用火苗糾正。

1. Frozen. This is also very easy to cause damage to the engine in winter. The cracks of the engine body can only be repaired by spray welding at the position without bearing force. First, drill holes on both sides of the crack to stop the crack, then plant several nails along the crack, and then vertically divide several pieces of repair plates along the crack direction, and use low-carbon steel welding rod to weld firmly along the crack and the repair plate. Pay attention to tap welding with hammer while welding, and correct with flame after all welding.

2、左右平衡軸端205軸承孔損壞。這樣的事情務(wù)必立刻維修。軸承孔損壞比較輕時(shí)，可以用增加205軸承外圓法修復(fù)，在軸承外側(cè)用氧焊將剛絲對(duì)稱點(diǎn)在個(gè)小一點(diǎn)，用銼調(diào)整一下，隨后壓進(jìn)軸承孔就可以應(yīng)用。另一種方式是用2mm厚的不銹鋼板做一個(gè)內(nèi)螺紋為50mm的大平墊圈，在平墊和機(jī)體上做三個(gè)絲孔，用平頭螺釘固定不動(dòng)上來(lái)。當(dāng)軸承孔損壞比較嚴(yán)重時(shí)，可以鏜大原孔鑲套，并在嵌入的軸套和機(jī)體交接處做三個(gè)小絲孔，用螺絲固定不動(dòng)。

2. The left and right balance shaft ends 205 bearing holes are damaged. Such things must be repaired immediately. When the bearing hole is slightly damaged, it can be repaired by adding 205 bearing outer circle. Use oxygen welding on the outside of the bearing to make the symmetrical point of the rigid wire smaller, adjust it with a file, and then press it into the bearing hole. Another way is to use 2mm thick stainless steel plate to make a large flat washer with internal thread of 50mm, make three wire holes on the flat washer and the body, and fix it with flat head screws. When the bearing hole is seriously damaged, the original hole insert sleeve can be bored, and three small wire holes can be made at the junction of the embedded shaft sleeve and the body, and fixed with screws.

3、缸頭地腳螺栓孔滑絲或損壞。這樣的事情是因?yàn)榕ぞo缸頭螺帽時(shí)用勁過(guò)大或搗缸導(dǎo)致。如果是某些絲孔滑絲，可再次改絲，并生產(chǎn)加工一個(gè)與該絲孔配套設(shè)施的缸頭地腳螺栓就可以。假如絲孔損壞或好幾個(gè)絲孔滑絲則不可以修復(fù)。

3. The cylinder head anchor bolt hole is slipping or damaged. This kind of thing is caused by too much force when tightening the cylinder head nut or tamping the cylinder. If some thread holes are slippery, the thread can be changed again, and a cylinder head anchor bolt supporting the thread hole can be produced and processed. If the wire hole is damaged or several wire holes are slippery, it cannot be repaired.

4、砂眼。先用剛絲錐鉆孔，隨后用鋁絲塞住，或用焊接法塞住就可以。

4. Trachoma. First drill with a steel tap, and then plug with aluminum wire, or plug with welding method.
