聽(tīng)力每日練習(xí) listen 2757 Mechanical?problem

1-- Why have you stopped production?
 
2-- We've had a few problems. One of the bolts has worked loose and a blade has snapped off.
 
1--OK. Make sure the power is switched off then tighten up all the bolts on the unit and replace the broken blade. Why is there oil all over the floor?
 
2--I think the valve is faulty. J^couldn't regulate the pressure and the seal burst.I tried opening the emergency valve but it was jammed.
 
1-- Clean up the mess first, then fit a new seal and check the valve.
 
===================================
注解：
 
1.production生產(chǎn)
2.blade刀片
3.burst爆裂
 
===================================
譯文：
 
1--你為什么停產(chǎn)？
2--有點(diǎn)問(wèn)題。有個(gè)螺栓松了，一個(gè)刀片折斷了。
1--哦。一定要關(guān)掉電源后旋緊所有的螺栓并更換刀片。為什么地上到處都是油？
2--我想是閥門的故障吧。我沒(méi)法調(diào)節(jié)壓力，墊圈破了，我試著打開(kāi)應(yīng)急閥，但是堵了。
1--首先清除臟物，然后換一個(gè)新的墊圈并檢查一下閥門。
