FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served

Q: i want to make a bulb on and off at intervals of say half an hour. readymade timers available in shops(india) costs much and does not support shorter intervals like half an hour. any cheaper electronic circuit which can do this control? from where can i get the circuit or its diagram?: Depending on your skills, a CMOS 555 timer chip could probably drive a solid state switch (triac) for this interval although a more reliable timing, especially if you want exactly a 50% duty cycle, by feeding the timer output into a counter, so that the 555 cycles say 32 times (once a minute about) for each change of state of the selected output. Smaller cycle times are more stable.

Q: I would like a serious answer from a professional who would know about these things from being part of the military or etc.When the air burst missile exploded, everything electrical stopped working. At the end of the movie, the girl asked if the phones are working and the guy replied Are you kidding, they'll never be phones again.Is that a true statement? Can anything electrical ever work again?? Or did he say that because the world at the time in their point of view looked unrepairable ?Also, if I was in a well constructed fallout shelter with all my stuff and I wanted to save Computers, TV etc. will it get affected from the outside air burst missile? (I know a lot of people are gonna yell why keep those when you can't use electricity again after a nuclear war 1, I just wanted to know, 2 I could use them in the shelter if I have Generator batteries for room lighting and everything else): You are referring to electromagnetic pulse. The strongest part of the pulse lasts for only a fraction of a second, but any unprotected electrical equipment — and anything connected to electrical cables, which act as giant lightning rods or antennas — will be affected by the pulse. Older, vacuum tube (valve) based equipment is much less vulnerable to EMP than newer solid state equipment; Soviet Cold War–era military aircraft often had avionics based on vacuum tubes due both to limitations in Soviet solid-state capabilities and a belief that the vacuum gear would survive better. On the other hand, the solid state PRC-77 VHF manpack radio survived extensive EMP testing. The earlier PRC-25, nearly identical except for a vacuum tube final, had been tested in EMP simulators but was not certified to remain fully functional.

Q: examples of electrical equipment in which insulators and conductors are used.and give reasons for their usethxthe one that answers will get 10 points: insulators are used on wires and places you don't want electricity to flow conductors are used in circuit boards and almost every electrical component. conductors are used to carry the flow of electricity.

Q: Hi, I have an interview for an electrical engineering position with my city water district. I have a power and drives background but I am pretty sure that they are not a utility company. What exactly do electrical engineers do at the water cleaning districts? I appreciate anything response I can get. Thanks in advance.: The water district is a public utility. If they did not need someone with your skills, they would not have asked you for an interview. They use a lot of pumps, motors, and other electrical equipment. good luck with your interview.

Q: I 'll be close to Main Station Cornavin in Geneve: Check okorder

Q: direct tv came to the house we just moved into and the power went out when he was hooking up a reciever and turns out all our outlets are messed up except two. one is completely dead. one was red on his tester thing and he said that is dangerous--forgot what he said about it and all the other are open ground i guess, and the fuse keeps blowing. is there any way to fix it without an electrician??? my husband knows some electrical stuff thanks: You should get a electrician. It is a fire hazard and nothing to fool around with.

Q: How long did it take you to complete? What job do you have now? I am interested in going to school for that and wondering what type of jobs I might have.: I am currently studying to be an electrical engineer. It takes on average 5 years to get a Bachelor's degree. However some schools offer yu the chance to also obtain your masters in 5 years (requires alot of extra work). Electrical engineers have a wide gambit of job options. Often they involve jobs with heavy analytical problem solving, you also will be very fluent in mathematics as you will probably be required to maintain an astute understanding of calculus and physics. My father was is/was and electrical engineer who fixed medical equipment at hospitals, a field engineer. You may also be hired for you ability to solve problems rather than technical skills. It all depends what ou want to do though. My major electrical engineering with a robotics focus, so there are alot of jobs for electrical engineers.

Q: I don't know a lot about electricity, but I know that on earth we ground our outlets, computers, etc. Do they have a means of grounding electricity in space? Are electrical systems more dangerous on spacecraft?: We do not ground all electrical equipment. Much of it is double insulated. Grounding simply connects the chassis to Earth, so that if there is an electrical fault that makes the chassis live this is short to Earth and a person, who we might expect to be standing on Earth and not hovering, will hence be at the same potential as the chassis. The actual circuit is not grounded - its return path conencts to neutral. Precisely the same principle can be used in space, but in light of the fact that people in space may actually be floating, double insulation is safer.

Q: If an electrical equipment is designed for 220V at 60Hz, can it be used in a country which uses an electrical system of 240V at 50Hz. I'm not sure how true is this, but I've heard that the voltage would not be a problem but if the frequency is less, electrical equipments with motors will not be able to run at 100% performance which means the efficiency drops. Please enlighten me~Thank you: YES,it did. 50 hz AC motor becomes less torque while running with 60 hz power,because it has too much reactance (more turns of coil). Whereas 60 hz AC motor is running faster with 50 hz power and its life is shorten,because it has not enough turns of coil.

Q: anyone knows some practical situation when a resistance maybe used to model part of a circuit, a component or electrical equipment: english.cxem /infrared/ir3-5.g Anita
