Q:Is the Ronshen refrigerator made of brass tubes or made of aluminium tubes?!
In general, the condenser in the box is straight seam welded steel pipe, and the evaporator is made of copper tube and aluminium pipe. I hope it works for you.
Q:What material can be used for welding aluminum copper tube?
Now there is a new type of copper aluminum welding technology!M5151 is a universal design for repair welding alloy, all white metal, including zinc die castings, aluminum, lead, copper lead alloy and tin antimony lead alloy, can be any of the above types of metal and copper, brass, steel, stainless steel or bronze and other metal welding. The utility model can be used at ultra low temperature at 179 DEG C and hardly needs preheating. Tensile strength up to 13 kg / mm2.
Q:How long can the air conditioning aluminum tube take?
The sky see now actually used outside heat shrinkable tubes of the copper tube, do not look carefully thought is copper
Q:Eddy current demonstrator's working principle: why does the magnet fall at different speeds in different aluminum tubes, while the aluminum tubes are the same?
This is eddy current resistance. Used in a vibration system, that is, electromagnetic damping. The permanent magnet moves in the aluminum tube, and the magnetic field produced by the eddy current in the aluminum tube will resist the change of the magnetic field, that is to impede the movement of the magnet.
Q:Is the tube of LED lamp all plastic tube well or half plastic half aluminium tube?
All plastic tube is one of the most widely used early, because the main use of non isolated power supply, in order to avoid electric shock problems, so I hope to use more plastic tube. Which is used with Phi 5 straw hat tube LED. The fluorescent lamp is the biggest problem due to the heat radiating, all sealed in the tube, unable to escape, life is very serious, coupled with the straw tube had life is very short, less than 2000 hours on the bad.Semi plastic half aluminum LED fluorescent lamps sold on the market are basically the half PC Aluminum Alloy, in the half light of the use of plastic in need not pervious to light and need the half cooling on the use of Aluminum Alloy.
Q:What happened to the mold sticking when drawing the aluminum pipe? How do you make the mold?
1. apply mold release agent on the mold.2. the necessary taper shall be taken into account in the design of the die.3. punch opening and exhaust hole.4. charging and discharging device.5. improve the mold finish.6. mold surface treatment of titanium.The main purpose of the mold surface treatment is to improve the surface hardness, wear resistance and corrosion resistance, etc., so as to improve the quality of mold products, and extend the service life of the die. Reasonable application of surface treatment technology to obtain high precision mold surface is the necessary condition of high precision and good surface quality products. The cost of the surface strengthening process is lower, but the service life of the die can be improved by 5~10 times or even several times, and the economic benefits are obvious.According to the present application status of China's mold surface treatment technology, I published by the user survey found that, at present, surface treatment technology of mold manufacturing enterprises mainly used or in surface hardening, carburizing / traditional nitrogen technology, electroplating and chemical plating technology, and these technologies have varying degrees of surface hardness distribution all the heat treatment deformation and other aspects of the problem difficult to solve. For the future technological transformation, the common concern is the application of new technologies, such as surface coating technology, TD coating treatment technology, laser surface strengthening technology and electron beam strengthening technology. Below we specially invited several industry technical experts, respectively, the user's attention to these deep into the discussion, and hope to benefit the general mold enterprise technical upgrading.
Q:Does the refrigerator pipe system leakage within the snow, what glue trap.... I am not burning burning aluminum.
I used AB glue, repair it for a few years, no problem, it is on the low pressure sideAskUsed at high voltage, OK?Chasing the answerNo way
Q:Haier refrigerator is now using aluminum tube material,
The best thing about a refrigeration pipe (household system) is a copper tube. They replaced the copper tubes with aluminium tubes because the aluminum tubes were cheap and the oldest refrigerators and freezers were all copper. Trachoma basically does not have unless the welding mouth is not welded well.
Q:How can the refrigerator be welded with copper aluminum tube?
Welding powder, copper electrode can be used welding!
Q:Can 304 stainless steel aluminum pipe be welded with 6061?
304 stainless steel tube 6061 aluminum tubes, dissimilar metal welding.Method for welding friction welding, stainless steel tubes are respectively fixed on the friction welding of two fixed chuck open welder for rotation, two workpiece contact surface friction heat, through the pressurizing the two dissimilar metal contact oxidation layer is damaged, is to continue to operate a two joint welding effect metal.
