Q:What does to dowel an equipment mean? (referred to rotation machinery)?
It is a process where a piece of rotating equipment is fixed to its base once it is fully aligned. This is over and above the use of anchor bolts. It is not always done and some believe it is an unnecessary step in equipment alignment. Typically a hole is drilled through the equipment and the base. The hole is tapered and a tapered rod or dowel is driven into the hole. With two dowels, a pump or compressor can be held so it will not slide around and if moved can be put back in the exact place it should be.
Q:How to detect any problem in used machinery?
When you go out to buy a used machinery, try to search for the sites online which offer quality services and affordable deals. As these sites would guide you throughout the buying process. You would get solutions to all your problems from an expert.
Q:List four fundamental differences between bacterial and eukaryotic transcription machinery.?
Bacterial - RNAp is only of 1 type and has 5 subunits. - Sigma factor does the promoter recognition. - alphaCTD is not involved in the RNAp control, but instead binds UP elements - Poly(A) tail is not added to the RNA produced. - No introns are present, hence no splicing machinery. - GTFs are absent. - The process is relatively simple. Eucaryotes - RNAp is of more than 4 types and has about 12 subunits. - TFIIB and many other factors do the promoter recognition. - CTD of RNAp plays important role in regulation and elongation and many other processes. - Poly(A) tail is added to the RNA produced. - Splicing machinery is present due to need for intron splicing - GTFs are present. - The process is relatively very complex.
Q:How to prevent engineering machinery failure
Before the inspection and maintenance: radiator water level; engine oil pan; fuel tank oil, hydraulic oil quantity, gearbox oil, brake fluid; sealing the tubing, pipe, pipe and other components; battery terminal; foot brake, hand brake lever of the reliability of the work; is flexible and placed in a neutral position; the tire pressure is normal; rim bolt, bolt bridge, drive shaft bolts and other bolts are loose;
Q:Construction Machinery Help?
not me
Q:how much is a 2007, 13hp central machinery, gas engine cost?
Used, it is almost worthless. Not a name brand. 6 years old. Maybe $25.
Q:who is the real name of the machinery of death?
Say please. Then ask an understandable question..
Q:What is better Catapillar or Case machinery?
Driven Cat's in the mines (u/g artic trucks AD45, 55 and 55B, graders, 777 769). Proof of the pudding is in the tasting they say, and all mines are full of Cat gear. Im not sure about Case to be honest, but Cat gear is excellent.
Q:Which is better, motor or diesel, on construction machinery?
The working condition is relatively stable, and the matching motor or the diesel engine will be the same, better than the working conditions. Little effect on choice. In contrast, the purchase of motor driven construction machinery will also cost less.
Q:What are the advantages/disadvantages of using machinery in farms?
I find tractors a big help to carry heavy loads plough the fields cut the hay and carry big bales of hay/straw..so thats an advantage farm machinery make farming a bit easier and you are able to do work quicker (i.e harvesting) and with out the need of to many labourers and less physical strain... disadvantage: they can be dangerous if not used/handled properly they can be expensive to buy compare to employing workers need fuel and maintenence which can be expensive they are not environmentally friendly
