The purpose of setting up the air storage tank is as follows: (1) to store air volume, on the one hand, to solve the contradiction of air consumption that may occur in the system in a short period of time, on the other hand On the one hand, it can be used temporarily when the air compressor fails or other emergencies (such as power failure); (2) Eliminate or weaken the pulsation of the air compressor output airflow, stabilize the air source pressure, and ensure the continuous and stable output airflow; (3) ) to provide a more stable system capacity and pressure, prolong the "start-stop" or "load-unload" cycle of the air compressor, and reduce the switching frequency of electrical equipment and valves.

As we all know, the air contains moisture. After the air is compressed by an air compressor, the moisture in the air will have an aggregation effect, forming water droplets or even stagnant water. The compressed air produced by the air compressor is used by various equipment, and the air with moisture will affect the life of the equipment, so it is necessary to dehumidify the compressed air. In the existing compressed air supply system, a cold dryer is generally installed behind the air compressor to dehumidify the compressed air, and the compressed air dehumidified by the cold dryer is stored in an air storage tank for use by subsequent equipment. This kind of dehumidification equipment consumes a lot of energy, and has a complex structure, which is prone to failure.

Due to the different density of water droplets and gas, under the action of centrifugal force , the water droplets are thrown to the cylinder wall and slide down to achieve the purpose of dehydration. At the same time, the cylindrical cylinder is fixed on the lower head through the fixed bracket to avoid the movement or deformation of the dehydrator due to the impact of high-pressure gas, which affects the use effect; in addition, the inner wall of the tank A ceramic protective film is attached to enhance the corrosion resistance of the tank.

Since the outer wall of the tank is provided with reinforcing ribs, the strength of the tank body is enhanced.

Because there is a pressure sensor on the upper head, and the pressure sensor is connected to an audio alarm device, when the pressure reaches the set value, a sound prompt will be issued to notify the staff to close the inflation valve, and because the top of the upper head is equipped with a safety valve, When the set pressure value is exceeded, the safety valve will automatically open to play a role of safety protection.
