The air compressor that has been used for so long， How is your Air tank？
Many people may be familiar with air compressors,But may have been confused Why is there always such a big air tank connected behind the air compressor,What is the use of air tank?Here is a little bit of knowledge about air tanks for everyone
Why Named Air Tank?
One is the function of storing gas to prevent the system pressure from falling when the load increases sharply, so it is called a air tank. The second is to play a buffering role, reducing the air flow pulsation at the outlet of the air compressor, also called a buffer tank
What is the function of the Air tank?
1.Dewatering and degreasing function
The large surface area of the air tank can initially cool the compressed air, so that part of the water and oil are condensed and precipitated, which has a certain effect of dewatering and degreasing; reducing the load of subsequent drying and degreasing equipmen
2.energy saving effect
The air tank has the effect of stabilizing and maintaining pressure. When the system pressure is above the start pressure of the air compressor, the air compressor will be in a shutdown state, which can avoid the frequent start and stop of the air compressor and waste electric energy
3.Protect air compressor
As a power equipment, if the air compressor is frequently started and stopped during work, it will increase the wear of the valve. On the other hand, the oil circuit and the gas circuit are unstable, which will cause damage to the equipment parts. If the air tank is configured, it can be avoided The frequent start and stop of the air compressor can protect the air compressor
4.Provide a stable air source
The air tank can ensure that the gas source is maintained within a certain pressure setting range, and the back-end gas system can obtain a constant pressure, which is essential for the gas supply in the factory
Precautions of when using air tanks
1.Clarify theme materials and specifications
When purchasing a air tank, you must select the type according to the gas volume and pressure level, choose products from regular manufacturers, ensure the quality of the main materials of the air tank, and prevent uneven steel plate thickness, substandard mechanical properties, and welding defects that directly affect the storage. The safe use of air tanks.
2.Equipped with necessary safety accessories
According to the requirements of safety inspection regulations, the pressure vessel must be equipped with an overpressure relief device (safety valve or bursting disc) and a pressure gauge according to the design requirements; in addition, for the air tank behind the piston machine, it should be placed between the piston machine and the air tank. Install a check valve; between the compressor and the check valve, a vent pipe should be installed, and a muffler should be installed on the vent pipe; a shut-off valve should not be installed between the piston air compressor and the air tank; but the air tank and the gas supply A shut-off valve should be set between the main pipes.
3.Prevent pipe vibration
The suction and discharge process of the air compressor is intermittent, causing the pressure and speed of the airflow in the pipeline to be pulsating and periodic, which will cause the pipeline to vibrate. If the air tank is installed improperly, the base is not fixed, and the installation distance between the tank body and the air compressor is not installed according to the design requirements, the pipeline vibration will be aggravated, which will cause the various connection parts to become loose due to repeated vibrations and other hazards, and at least leaks. Heavy will cause an explosion
4.Prevent oil accumulation in the tank
The front air source uses an oil-lubricated air compressor, which will bring in a large amount of grease with the compressed air, and particles such as rust or dust will easily form sediments in the air tank and cause oil accumulation. Accumulation of static electricity or other improper operation may cause spontaneous combustion and explosion. Therefore, it is necessary to do a good job in the drainage of the gas storage tank, strictly control the discharge temperature of the compressor, set up grounding protection, and strengthen the compressor suction filter and compressor Back-end pipeline oil removal filter, etc.
