Is timing required in the process of producing acetylene? Could someone explain to me the process involved in this timing, and how long it usually takes, for example, what changes occur and why.
Help you move to the specialized section to take a look
First of all, it should be noted that the meaning expressed by the original poster is not very clear. Based on my guess, what you mean by “timing” refers to the time required for one storage tank (or the upper storage tank) to be emptied. When calcium carbide enters one of the storage tanks through the feeding hopper, the acetylene gas in that tank needs to be replaced with nitrogen before calcium carbide can enter; otherwise, if the replacement is not proper, acetylene will mix with air and reach an explosive level； During the discharge process of calcium carbide, sparks are generated as a result of the collision between pieces of calcium carbide or between these pieces and the walls of the container; when the conditions for an explosion are met, an explosion will occur. Therefore, it is necessary to strictly control the replacement time, and strict control of this time is the most effective way to ensure safe production. -----I’m not sure if what I’m expressing is what the original poster wants to know.
“Could someone explain to me the process involved in this timing, and how long it usually takes, for example, what changes occur and why. ”------As for the time required, it depends on the size of the generator. In the past, when the generators were smaller and had lower capacity, as well as smaller storage bins, it was relatively easy to carry out the replacement process; I remember that it took 5–7 minutes for us to complete such replacements. If the generators have higher capacity, then the time required will be longer. In fact, the owner can determine the indicators based on experimental data, by conducting statistical analyses on samples taken at different times. When a pattern is identified – that is, when the sample values are always greater than 0.5% after a few minutes of replacement – the minimum target value can be determined. It would be even better if your facility has gas detectors; by using these detectors to take readings at different times at the sampling points, an empirical value can be obtained. In the future, as long as the replacement is done after this time period, it will be fine.
What’s needed is a professional answer like yours; thank you in advance. Generally, is it necessary to perform timing operations frequently during the acetylene production process? And how long does each timing operation usually last? Or what are the requirements for clocks and watches?
The requirement for clocks is that they function properly, with the error remaining within acceptable limits.
The error being within the allowable range – what exactly is that range? Is there a specific value? Thank you.
I’m not familiar with the industry standards for watches, so I can’t answer you.
