Is designed with ac/dc motor cooling products, the advantages of small volume,
good cooling effect, low noise, small vibration, maintenance, easy installation,
energy saving, especially suitable for lack of water and dust environment.
Working principle:
ZTL knapsack type air - air cooler is a cooling of the independent components,
and motor installed it into a whole, to form a closed cooling system, through
the circulation fan and cooling fan run to the hot air through the cooling pipe,
motor, a constant cold air cooled by the outside world, thus ensuring motor
safe and reliable operation under the rated conditions.
Motor cooler is the main heat transfer components, is one of the important products
to maintain motor operation, a direct impact on the rise of temperature of the motor,
the output, and life, all of the steam turbine generator, hydraulic generator, ac/dc
motor use cooler, application scope is extremely broad, play an important role in the
national economy and people's livelihood.
An electric motor exhaust air cooler is 20 M ^ 3 / MIN cross-sectional area is 0.085 M ^ 3
wind speed can reach?Through air volume equal to 20/60 = 0.33 cubic meters per second.
By the cross-sectional area is equal to 0.085 square meters.So a second average wind speed
is equal to the ventilation rate divided by the cross-sectional area is equal to 0.33/0.085 = 4 m/s.
- Q:I am a mechanical engineer with limited EI information. In general terms, could someone succinctly describe the following terms: (a) HMI; (b) Gen-set; (c) PLC; (d) UPS; (e) SCADA / Citect; (f) MCC; (g) E-Stop; (h) PCS/SIS; (i) Murphy switch. I know it's a lot, so relatively short answers should be fine - just summed up concisely and correctly. Thanks in advance all you electrically-savvy people!
- HMI Human Machine Interface Gen-set Engine generator set for generating electricity PLC Program able Logic Controller used in factory automation UPS Uninterruptible Power Supply SCADA Supervisory Control And Data Acquisition industrial control system using HMI and PLCs Citect the software company that specilized in SCADA control MCC Motor Control Center E-Stop Emergency Stop Stop Control PCS/SIS PCS (Process Control Systems) and SIS (Safety Instrumented Systems) Murphy switch shutdown switch actuated when process parameters are not correct, like shutting down an engine when engine oil level is critically low.
- Q:I recently came across an article that many Jews are now reevaluating whether electricity really is tantamount to lighting a fire, a forbidden act on the Jewish Sabbath, due to advances in our understanding of electricity through modern science. Is anyone aware of changing opinions on the use of electricity on the Jewish Sabbath? Are some Orthodox groups really changing their position?
- There's a difference between changing your opinion and changing your position. Not all electrical devices create a spark when they are turned on, but some do (incandescent light bulbs, for one obvious example). But because it has become accepted practice that observant Jews don't turn any electric devices on or off on the Sabbath, I am pretty sure that barring a new technology replacing electricity, it will continue to be prohibited. A parallel example is that of kitniyot on Passover. There is absolutely no Torah basis to conclude that corn, rice, etc., are chametz. The reason that they were classed along with chametz as forbidden grains had to do with the way mills worked at the time of the Talmud - that since they could all be ground into flour, and mills often ground every type of flour, they could become corrupted with chametz. Nowadays, it is rare to find a mill that grinds all types of grains into flour indiscriminately, and beyond that, FDA regulations require flours to be properly labelled - especially in this era of severe allergies. So there is no longer any logical reason to forbid eating kitniyot on Passover. And Sephardic Jews (depending on the community) do eat many of them. But even though this is accepted wisdom and has been for years, nevertheless, the laws are not being negated. After a certain period of time, the practice becomes the law. And once it's the law, it stays that way.
- Q:I'm a student looking for things that are involved in R and D aside from Scopes, Logic and Spectrum analyzers, Signal and Waveform generators and VNAs. Things outside of what Tektronix, Agilent and Lecroy would be involved with.
- You will be constructing experimental devices, for which you will need a complete machine shop and a selection of hand tools. Sooner or later you will need a good cappuccino machine, or at least a drip coffee maker.
- Q:I quest it will be a big surprise to everybody. a) He will make a big party on earth. b) It will be a new beginning. c) It is the end of the happy moment on earth.
- hes going to update his facebook: Im back yall!! 2 billions christians like this
- Q:i dont understand this, every surge protector claims to protect phone lines from surges but why?
- Because DLS and phone lines operate on voltages and currents and are susceptible to lags/spikes. GL
- Q:I own a manufacturing facility in NJ, I have an electrician on staff. does he need to be licensed? can he run new wires and install panels if inspected? it is only work within our building.
- As long as the work meets the NJ building codes, is inspected passed, I think you're OK. Personally, I would want my staff electrician to hold a valid license.
- Q:during line to ground fault, is there really a current that will flow in the ground, how will the grounding rod help if there is no connection back to the source? please explain how grounding aids tripping of C.B's
- In maximum mainscontinual distribution structures, the impartial is grounded at the substation transformer and usually at the get right of entry to element to human being premises. If a fault takes position which leads to a stay conductor entering touch with an uncovered conductive section of the package, any cutting-edge will bypass to floor and holiday a circuit breaker.
- Q:hiwhenever there are clouds, lightning or clouds sparks strikes my house and damage my electrical equipments like tv, fan, lights. my house has an entrance from south side and have windows, doors openings from this side, i also have openings in north direction to access to my back verandah but no sparks fall from this side. The house have 3' high iron bars fencing at front wall of 5' height as well as on rear wall of 5'-6 height. Do i need to put one 1'-6 high lightning rod made up of copper and aluminium and placed it on the roof top of my house to arrest these lightning sparks whenever they fall or some lightning arrester or you have any good solution of my problem. my house is 39' wide and 52' in length and 33' high(including ground floor,first floor, second floor) and have flat roof top and its in haryana region. please suggest me what to do? i will be really grateful to youthanksbye
- You Have the answer in your question you basically have to use a lightning arrestor an top of your house. But make sure that the earthing of it must be separate from your house earthing and try to maintain a earth voltage around 1Vlts preferably below 1 Volt. For more information on lightning arrestors go to the link below.
- Q:does adjusting the router's position about an inch or adjusting the direction of the antenna affect my laptops browsing speed?
- Not so much. But moving it away from other electrical equipment will make the signal travel farther. Also keep it as far from the cordless phone and things like that. Other digital devices, and concrete/brick walls really break it down. If you are connected to the access point at even a fair signal, you will probably be using all your internet connection speeds' bandwidth. Having a better signal wont make it faster, unless it is actually disconnecting on you.
- Q:I need the data for our researchif possible the producer price index for electrical equipments like transformers.
- sry my friend! have you looked it up through online?
