  What are the importance of cylinders in the canning of liquefied petroleum gas cylinders

  Some people say that weighing is the starting point and stop of an enterprise, just like warehousing, raw materials and the market, it is closely related to the production and operation of the enterprise. Liquefied petroleum gas is a basic chemical raw material and a new type of fuel, and it is well-known that liquefied petroleum gas is filled in steel cylinders. But for a large liquefied petroleum gas filling company, the filling of Lpg Cylinder Gas is definitely a challenging "work". To fill all kinds of steel cylinders safely and accurately, an electronic cylinder scale is the most important thing.

The importance of steel cylinders in the canning of liquefied petroleum gas cylinders

  Electronic cylinder scales are mainly used in liquefied petroleum gas filling companies for two purposes, one is for the weight inspection of steel cylinders, and the other is for filling. "Liquefied Petroleum Gas Cylinders" lists 6 types of LPG cylinders, including YSP4.7/YSP12/YSP26.2/YSP35.5/YSP118/YSP118-II.

  In other words, there are mandatory standards for the filling weight of various volume steel cylinders. For example, the filling standard of YSP-15 series cylinders is 14.5 kg, with an error of 0.5 kg. These regulations are not difficult for small filling companies, because most of these small companies use a fully manual mode of operation, and the staff can adjust the filling scale at any time.

  However, for large and medium-sized filling companies that use semi-automatic assembly line systems to operate, there is a problem that lies ahead, that is, the country does not have a unified regulation on the weight of steel cylinders, and a part of residual liquid will accumulate inside the steel cylinder during the recycling process. As a result, the weight of steel cylinders is not uniform, which brings great inconvenience to daily filling production.

  Companies use many methods to deal with this problem: the first is gross weight filling and net weight filling. Net weight filling means that the weight of the steel cylinder after the scale is not counted, and only the specified weight is filled into the cylinder. This method has a big disadvantage, that is, the electronic scale cannot judge the weight of the residual liquid in the cylinder. As a result, after the specified 14.5kg of LPG is filled into the cylinder, the weight of the LPG in the cylinder is overweight. The gross weight filling refers to filling the appropriate amount of gas to make the overall weight of the cylinder reach the national standard. This method also has shortcomings. The electronic filling scale is still unable to judge the weight of the residual liquid in the cylinder, and the result is often that the filled liquefied gas is less than 14.5kg. Neither method can pass the random inspection of the State Bureau of Quality and Technical Supervision.

  At present, many large and medium-sized liquefied petroleum gas canning enterprises adopt the classified filling method. It is to accurately measure the weight of the cylinder itself before filling, and then mark the cylinder according to a certain weight range. In this way, the cylinder scales under different marks can be filled by simply adjusting the program of the filling scale. This method requires a lot of pre-weighing work and is also the main work link of the cylinder scale.

  The electronic cylinder scale can weigh steel cylinders of various specifications with a diameter of 0.41m. Companies can use the upper and lower limit alarm function of the cylinder scale to monitor the weight of the residual liquid in the cylinder. For example, the self-weight of the YSP-15 specification steel cylinder is 16kg, and the company can set the upper weighing limit to 1718kg. When the residual liquid in the cylinder exceeds 1 to 2 kilograms of the cylinder, an alarm will be issued immediately, and the staff can further process the cylinder with excessive residual liquid. .

  Now you have a deep understanding of the "importance of cylinders in the canning of LPG cylinders". If you have any other questions, you can call Tianlong LPG Cylinder Company. Thank you.
