The relationship between tank pressure and volume

The relationship between tank pressure and volume

In the last article, we introduced the Maintenance method of low temperature storage tank. Today, we will talk about the relationship between the gas pressure and the gas volume of the storage tank. The gas storage tank can be divided into many kinds according to the different pressure, including low, medium, high, negative pressure, etc. There is no direct relationship between the volume of gas in a tank and the pressure, but they complement each other. The capacity selection of the gas storage tank brand mainly has the following two bases:



1, according to the air output of the air compressor to determine: because the gas storage tank if it is directly connected to the back of the air compressor, its role is to play a buffer role. At this time, the size of the gas storage tank can be calculated according to the exhaust volume of the air compressor. Usually, the volume of the gas storage tank is equal to one third to one fifth of the exhaust volume of the air compressor.

2. According to the gas consumption of the gas equipment, the capacity of the gas storage tank is determined: the larger the gas storage tank is, the longer it can be maintained. This is mainly to consider that when the air compressor fails or is repaired, the gas volume of the gas storage tank should be maintained to maintain the normal work of the gas equipment and ensure the normal operation of the production. According to the unit time consumption and to maintain the time to determine the capacity of the gas tank.



The pressure of the gas tank is equal to or greater than the pressure of the air compressor. For example, the air compressor with 12 kilograms of pressure should be equipped with 12 kilograms of gas storage tank. Or 15KG can also be done, but it can not be too large, otherwise it will cause unnecessary waste and damage to the air compressor. It is an indispensable part of the air compressor system, and there are many points to be noted when installing the gas storage tank. The brand of gas storage tank belongs to special equipment pressure vessel, mainly including simple pressure vessel and fixed pressure vessel. The installation instructions of the two types of products are also different, of course, the installation costs are also different.

Simple pressure vessel gas storage tank refers to the gas storage tank with simple structure and relatively small risk. It does not need to be registered for use, and it is also simple to be installed. It does not need to be inspected regularly in accordance with the pressure vessel regular inspection rules during the recommended service life. The gas storage tank pressure vessel certificate should be taken to the local special equipment inspection institute for testing.
