听力每日练习 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.

译文：
 
1--你为什么停产？
2--有点问题。有个螺栓松了，一个刀片折断了。
1--哦。一定要关掉电源后旋紧所有的螺栓并更换刀片。为什么地上到处都是油？
2--我想是阀门的故障吧。我没法调节压力，垫圈破了，我试着打开应急阀，但是堵了。
1--首先清除脏物，然后换一个新的垫圈并检查一下阀门。
