Q:When welding the refrigerator copper tube and iron pipe joint, what welding rod should be used?
My home two days ago on the repair of the refrigerator, but also welded copper pipe, the compressor is broken, to change, I see the master is used, the flame of the gun operation
Q:Why use copper tube for air conditioning?
Because the copper tube has better anti-aging property, it is not easy to oxidize in the air. The strength and toughness are better, and the adaptability of temperature is better than other materials. Weldable.
Q:How much is the copper tube for the air conditioner?
The copper tube in the air conditioner is good. Generally speaking, the meter is calculated. That is to say, how much is it per meter?. The price of one meter varies from 20 to 40 yuan.If it's a scrap, it's between 15 and 30 yuan.
Q:The air conditioner is not cool cool thin copper thick pipe room is going on is not cold air compressor bad again
This is obviously a lack of refrigerantFirst of all, to ensure that indoor and outdoor cleaning, ventilation smooth, but also to ensure that the normal work of air-conditioning basic conditions, including indoor filter screen, outdoor fins clean. Recommend cleaning at least 2 times a year, according to the use of it!In fact, air conditioning refrigeration is not good or not refrigeration, not necessarily is the lack of refrigerant, in the air quality is no problem, installed in place, the air-conditioning used more than the design life will not be lack of refrigerant.As a non professional, how to simply determine whether the air conditioning is lack of refrigerant, then observe and touch the outdoor machine, high and low pressure valve, frost situation and temperature bar.1, under normal circumstances, high pressure valve drying, and there is a certain Yu Wen (long working in refrigeration, there will be a small amount of condensate), low pressure valve moist and water dew, water dew according to the weather conditions.2, high pressure valve drying (long working in the refrigeration state, there will be a small amount of condensate), low pressure valve frosting, which is the lack of refrigerant.3, high pressure valve frosting, low pressure valve is frosted or dry, that is serious lack of refrigerant or system micro plug.4, high pressure valve drying is not cool, low pressure valve drying is not cool, the system is seriously leaking, or compressor does not work.
Q:The heat of copper in notebook is coated with thermal grease can reduce the temperature of it
The heat shield does not allow the surface of the uneven surface of the processor to contact the heat pipe. It has nothing to do with it. If you insist that it works, the radiator has a little more contact with the air
Q:What are the brass instruments for?
Recommendations to the piano for professional maintenance, if you insist on themselves to see you at what time, if the show will buy brightener (excellent maintenance expensive) if only their usual maintenance with YAMAHA brass maintenance oil (Shi Hui)
Q:How to spray metal paint on brass tube surface?
3, interval 3min spraying second times, and then use the cloth overall dust, second times don't mind the metal plaque, paint layer should be slightly thicker, spray area slightly expanded, not cover more than once4, spraying third times after the dust cloth dust, will spray paint quantity small, spray fan up, third times spraying, third times is to remove the metal plaque, slightly add some solvent to reduce the viscosity of paint
Q:Installation of air conditioners 19 and 10 copper tubes with 16 and 10 copper tubes can be used?
Well, the problem came out, we know that the liquid is compressed. When the liquid refrigerant from the suction port into the low-pressure compressor, will produce a "liquid hammer" phenomenon of compressor, this phenomenon is very serious damage to the compressor. This is a major problem, such as the rest will change the flow, increase the compressor noise and expansion valve and so on a series of problems.
Q:Outdoor air conditioner has two copper tubes, the two thicknesses are not the same, what are the tubes?
Compared with the size of two copper connecting pipe, thick thin tubular called bassoon, called, is connected inside and outside the machine, the inner and outer machine to form a closed system, the refrigerant inside and outside the machine can circulate normally go large gaseous refrigerant, go tubular liquid refrigerant as the root,, Flanagan, according to the air conditioning refrigeration and heating mode is differentIn the heating mode, the refrigerant enters the inner machine from the external machine through a big pipe and is returned to the external machine, the condenser and the compressor through a small tubeIn the refrigeration mode, the refrigerant enters the inner machine from the external machine through a small tube and is returned to the external machine through a big tube
Q:Tolerances for inner and outer dimensions of copper tubes? Fifty
Different copper tube standards, with different thickness and specifications of copper tube. The specifications of copper tubes include the thickness, length and length of the copper tubes. Purple copper tube thickness: general copper tube in engineering for water cooling more, need to consider the main water pressure, thermal properties. But the tolerance range will not be more than 0.5 millimeters, the inner and outer diameter of the copper tube is 1 millimeters.The characteristics of copper tube: light weight, good thermal conductivity, low temperature strength. Often used in manufacturing heat exchangers (e.g. condensers, etc.). It is also used for assembly of cryogenic pipes in oxygen making equipment. A brass tube of small diameter; used to transport pressure liquids (e.g., lubrication systems, oil pressure systems, etc.) and measuring tubes used as gauges.The copper pipe has a strong corrosion resistance, and has become the first choice for modern contractors in the installation of plumbing, heating and cooling pipes in all residential commercial premises.
