Q:How large air pump does 100W laser cutting machine use?
Add an adjustable switch just fine, size oneself can adjust!
Q:Is it better to use air blower or air pump hot air gun for mobile phone?
Classification of hot air grab:1, ordinary typeThe hot air gun is mainly temperature instability, fluctuated, cool instability. The scale of the wind gun is only adjusted to its power size, so the temperature is very slow when it is turned on for several minutes, and then the temperature rises linearly, and it will burn out if you don't pay attention. Such as public square, CPU, circuit board and so on. Although it also has temperature detection, it seems to be used only to protect the temperature, but not to adjust the temperature. I suggest that you do not often lose money in order to save money.2, standard typeThe hot wall of the real scale is used to adjust the temperature, heating up fast startup, tens of seconds to reach, and the temperature will not rise, in the range of similar adjustment, the air volume is relatively stable, suitable for mobile phone repair, I use the air gun is very good, such as the 3508 CPU not in more than 90% burn.3, several sub temperature displayThe performance of second, with basically the same, is a digital temperature display, some is very accurate. However, some display temperature is not allowed, it is prone to sleep. In addition, according to manufacturers and production sooner or later, long ago may not be practical.Add a point, digital thermometer measured, the actual use temperature is: (small head wind mouth) at the tuyere 350-400 degrees, a centimeter of about 300-350 degrees, 2 cm 260-300 degrees. A network of thermometers with digital thermometers can be tested.At the same time, some of the machines have power or other voltage and current indicating dials. Some parts can be replaced.If you're using a hot air gun without digital temperature, you can blow a piece of paper at 3 centimeters with the wind gun to estimate that if the paper doesn't get dark very quickly, it will be yellow as soon as possible.
Q:Domestic aquarium, air pump, oxygen pump, oxygen pump, what brand, good quality?
The quality of the general brand is very good, you can look at my information, according to the index index, I can provide you with a very good choice
Q:The family has a high pressure air pump that has been used to inflate tires
There is a gun head for car washing. The pressure driven water can be changed into high-pressure aerosol and can be used as a high-pressure water gun. And more water saving.I also saw this item at this year's auto show. I don't remember the exact name
Q:The bell is sounding in a glass enclosure, and gradually to glass pump pumping air
Is the bell sound, bell vibration. Air and glass is less, the bell sound more and more small, the air is completely out, when a vacuum is drawn, the sound will disappear; the ACD does not meet the B. problem;
Q:Do not let fish hypoxia, in addition to oxygen pumps and plants, what else?
You simply build a small fish pond, and want to make up the oxygen, only those two methods, and then higher point estimate in the future will appear...... Can you get some weed and mud in the river? Isn't it convenient? I keep it that way
Q:How to use vacuum compressor bag air pump
Method for using vacuum compressor pump:I. charging method:1. connect the pump to the 220V power supply.2. connect the inflatable fittings to the inflatable opening and turn on the switch to start charging ("-" means open, start charging, "O" means closing, stop inflating).3., pay attention to the inflatable valve should not be blocked, otherwise, the pump may be damaged by overheating.4., be careful not to use the air to inflate, please close to see our baby show in the suction port and inflatable mouth position.Two 、 evacuation method:1. open the air outlet for pumping the gas2. connect the right sized fittings to the suction port of the vacuum pump (if the suction port of the pump is just the right size, you don't need the three fittings). Connect the interface, then turn on the switch and start pumping ("-" means open, start pumping, "O" means "stop", "stop pumping").3., pay attention to the air valve should not be blocked, otherwise, the pump may be damaged by overheating.
Q:Which account should be included in the packaged air pump and circular saw?
1, packed with the air pump and the circular saw, if used for production, should be included in the "raw materials, production of materials"; if used for other purposes, and the value of 2000 yuan, it shall be included in the "low value consumable" or "management fees". If the value is more than 2000 yuan, it is directly included in the fixed assets". 2, the accountant's entry is as follows: Borrow: under construction, --XX projectCredit: raw materials / low value Consumables / fixed assetsCredit: taxes payable - VAT should be paid - the input tax should be paid out
Q:Does the oxygen pump for fish keep running?
If it's dense, it should be turned on
Q:How can the oxygen pump in the tank be out of oxygen, or pumping water, but without oxygen?
There's a good chance you're out of gas. It's blocked up. Just get a wire through it......
