Q:Which is better, the gasket?
You use this environment should be said to belong to the general conditions, not high pressure, high temperature and no corrosion, a lot of gaskets are met.
Q:What is the function of the washer between the end cap and the case?
Buffer, the amount of thermal deformation reserved.
Q:What is the difference between the sealing ring and the dust cap on the bearing?
Dust cover: an annular ring made of thin metal plates, fixed to a ring or washer of the bearing, which covers the inner space of the bearing but does not come into contact with the other ring or washer.
Q:How do you get that washer in the lid of the beauty cooker?
Try to buy a beautiful electric cooker. Ask the waiter and let her show you
Q:That's good. I know that. I just don't know what the machine is made of. Can you explain it in detail?Chasing the answerThere is a press, you go to the machinery factory to ask, you know
This mainly depends on what the medium in the tubing is and how much pressure it is.
Q:Why should the washer be fitted when the screws are installed?
Washers are divided into flat washers and spring washers. After the screws are tightened, because of the small contact area with the base, the installation of flat washers can increase the pressure area of the base and tighten the base, which will not cause the damage or sliding of the base. The spring washer increases the stress of the buckle and makes the fastening of the screw more fastening
Q:Where can I get the golf 7 taillight GASKET?
Hello, look at Taobao. [car has a problem, ask the car master. 4S shop professional technicians, 10 minutes to solve. ]
Q:304 stainless steel gasket, how sealed?
Hello, 304 stainless steel ring gasket if made, the sealing performance in general, sealed liquid should also improvise, but the sealing gas on the more difficult.
Q:Engine oil tank seal is not strict, how to do the oil spill?
Excessive exhaust emissions and three yuan catalytic converters have a lot to do, you can first clean the catalytic converters, try. The outer circulation air volume is small, may clean up the air conditioning filter element, the filter element plug can cause the incoming air volume to become smaller. The car door lock work is bad, you can first clean it, try, if the cleaning is not improved, then it can only be replaced by a new lock block. I hope my answer will be of some help to you. BITAUTO friends
Q:What gasket does the 9.8MPa pressure vessel flange seal?
You do not know what is the form of flange flange is not installed if ah, then I suggest you install the octagon gasket, see if the installation is a concave convex surface or two convex concave convex surface, if the installation of 10Mpa band steel ring graphite spiral wound gasket, if the steel ring with inner and outer two convex installation 10Mpa the graphite spiral wound gasket
