Q:Can I spray paint without an air pump?
Best not to spray, I borrowed a pump spray yourself a shoe and invisible door on their own, the effect is very poor, if there are ready-made can buy, or buy ready-made, unless you are confident of their own woodworking.
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:Air compressor, air pump room need to pay attention to what safety problems?
Depends on whether you are screw machine or piston machine. In short. Air compressor is to pay attention to drainage every day. More drainage in summer. Also, pay attention to the oil level of the observation machine. The check valve of the piston machine is relatively easy to break and consequently causes the motor to burn out. So don't be careful. Also pay attention to keep the room ventilation, so as not to lead to excessive temperature problems.
Q:How large air pump does 100W laser cutting machine use?
Add an adjustable switch
Q:How to install the inside and outside chamfer of piston ring of air pump?
The piston ring is chamfered outward, the piston ring is flat in the cylinder liner, and the interface must have a certain opening gap. The piston ring shall be mounted on the piston, and in the ring groove, there must be a certain clearance along the height. The chrome plated ring shall be in the first line, and the opening shall not be directed towards the eddy current pit at the top of the piston. Each piston ring opening is staggered at 120 degrees, and the piston pin hole is not allowed to be facing. Taper section piston ring, the cone shall be upward when installing. When installing the twist ring, chamfer or chamfer shall be upward. When installing the combined ring, the axial lining ring shall be installed, and then the flat ring and the wave ring shall be installed. The wave ring is provided with two flat rings, and a flat ring is arranged at the lower part, and the openings shall be staggered with each other.
Q:What kind of air pump is good?
Mute is the Shanghai Jaguar or Zhejiang's Austria (actually all the same, on the brand distinction). A while ago, I entered a Jaguar 2530 silent mute in Shanghai. It was very quiet indeed. In pursuit of small size, if it is mainly used for nailing, it is recommended that Jaguar 1509 (new model is FB-36/7) (motor 550 watts, cylinder 9 liters, gas production 102L/ minutes), enough nails. The model size of the gas cylinder is 1524 (motor 550 watts, cylinder 24 liters, gas production 102L/ minutes), nail and small area spray enough. I was 2530 (power 780W, 30 liters of gas cylinders, 165L/ minutes), a large area of painting is smaller, if not used in professional painting, with their own is enough. Another big number is 3540 (power 1100W, gas cylinder 40 liters, gas production 200L/ minutes), gas production is large, should be relatively cool with. The models listed above are for Jaguar in Shanghai. Buy air compressor, the most important thing is to look at gas production (and motor power related), followed by the volume of gas cylinders. Nail guns in pneumatic tools, the amount of gas consumption is minimal, so the general air compressor can do. Spray and spray gas consumption is great, the consumption of gas and spray nozzle diameter, large caliber high gas consumption, and professional paint, spraying with basic is the large diameter, so professional painting to large volume of air compressor. Own in home with fun, it is recommended to use the following 1 caliber spray gun, so you do not have to buy high-power air compressor. For example, if the amount of gas consumed by the nail gun is 20 litres per minute, and the amount of gas you buy is 80 litres, then nailing is enough. If you buy a 1 caliber gun, the gas consumption is 100 litres, compressor and gas production you buy is 80 liters, so when painting is very difficult, you have to wait for the process, if the compressor gas production is 120 liters, it is fully competent.
Q:Open oxygen pump goldfish why are you always floating in the water floating a few days and then he died.
First you fish disease, the disease is usually floating water, slows down the action, the latter will turn on the surface of the waterWhat's the matter? Water is the source of misfortune! The water was not taken care of, and many of the fish sold did not pay attention to the water quality, so he was sick when he was there! Why is it okay with him? When you buy fish, you don't see the fish well. Besides, the fish density is large and the oxygen supply is great. Sometimes you can't see the morbid state. And after you go home, you are a long-term farming, the environment has changed, morbid state emerged. Those traders will say what you don't have a good, what should be done, nonsense!Only a small part of the home is not good enough to catch the diseaseThe trick is to pick the fish! Carefully select, the owner of the real fish are bought in the fish shop when the fish just go, or a few days to observe the target fish shop fish, a week later found that the United States to buy the problemIs the control of water quality should be paid attention to in the home, the best is to change the water filtration system, 1/3 have no words for 35 days, don't put the amount of fish food, feed several times after You'll see. they eat much less, can do not much before the water goes bad easily. The fish must be disinfected first. Not only should the fish be isolated after the disease occurs, but the original tank must be thoroughly disinfected
Q:Where does the Audi A8 pump the fuse?
Landlord, ah, this is the other insurance together, in front of the copilot, you can look at.
Q:Do you need filters and oxygen pumps for small tanks?
Small tanks require the use of filters and oxygen pumps. This can greatly reduce the artificial burden of feeding. Let's take a look at what these two things play in a small fish tank:1, small fish in normal life will continue to breathe, reduce the dissolved oxygen content in water, in natural waters, because the surface area of water contact with the air, oxygen can quickly dissolved into the water to supplement. But in a small bowl, because the water and air contact area is small, and the feeding density is relatively high, so the content of dissolved oxygen decline will be relatively fast, once dropped to below 3ppm, the fish will continue to float, did not improve the fish will die. Oxygen pumps can increase water contact with air, increasing the rate of oxygen dissolution.2, the residual fish food, fish feces will decompose and decay under the action of microorganisms, forming ammonia and nitrite substances which are toxic to fish. When the concentration of ammonia nitrogen is greater than 0.02ppm or the concentration of nitrite is greater than 0.2ppm. Fish die of poisoning. The filter allows the flow of water to pass through the filter material, so that the nitrifying bacteria on the filter material oxidize the substance to form a basically non-toxic nitrate.If you do not have these two devices we can only rely on water for fish, more frequent to hypoxia and harmful substance accumulation, with these two devices can greatly reduce the frequency of the water, reduce the burden of artificial feeding.
Q:How do you set the air pump to 4 pressure?
Air compressor can generally set the minimum Qidong pressure and the maximum stop pressure, directly on the top of the tune on the line, and adjust the side of the bleeding, as set to 4 pressure.Working principleThe working principle of the air pump is that the engine drives the air pump crankshaft through two triangle belts, thereby driving the piston to pump up air, and the produced gas is introduced into the air storage tank through the air guide pipe. On the other hand, the air reservoir is introduced into the pressure regulating valve of the air pump through a guiding pipe to control the air pressure in the air storage tank. When the air pressure in the air cylinder to the pressure regulating valve to adjust the pressure, from the gas cylinder gas pressure valve can not enter the open top pressure regulating valve; when the air pressure in the air cylinder to the pressure regulating valve setting pressure, inlet gas pressure regulating valve from the gas cylinder top mixing pressure valve valve into the airway pressure valve and communicated with the transfer pump, and the normally open airway control pump inlet, so that the air pump load operation, to reduce the loss of power, to protect the pump. When the pressure in the air storage tank is lower than the pressure regulated by the pressure regulating valve because of the loss, the valve in the regulating valve is brought back by a return spring, and the control air path of the air pump is disconnected, and the air pump starts to inflate again.
